181-530: The Republic F-105 Thunderchief is an American fighter-bomber that served with the United States Air Force from 1958 to 1984. Capable of Mach 2, it conducted the majority of strike bombing missions during the early years of the Vietnam War ; it is the only American aircraft to have been removed from combat due to high loss rates. It was originally designed as a single-seat, nuclear- attack aircraft ;

362-583: A Boeing B-17 Flying Fortress or 10 five-inch (127 mm) High Velocity Aircraft Rockets . The first pilots to fly the Thunderbolt from England were Americans who had been flying Spitfires in the RAF before the U.S. joined the war. They were not impressed initially; the Thunderbolt lost out to the more nimble Spitfire so consistently in mock dogfights that these encounters were eventually banned. But by November 25, 1943 Thunderbolts had found their true niche, attacking

543-481: A terrain-avoidance radar capability, while a completely new instrument panel was fitted, replacing dial-type instrument with vertical tape instruments which were easier to read in combat. In order to accommodate the new radar, with a much larger radar dish, the forward fuselage was redesigned, increasing overall length by 16 inches (41 cm). The F-105D entered service with the 335th TFS in September 1960, although it

724-546: A $ 179.7 billion budget and is the second largest service branch of the U.S. Armed Forces, with 321,848 active duty airmen , 147,879 civilian personnel, 68,927 reserve airmen, 105,104 Air National Guard airmen, and approximately 65,000 Civil Air Patrol auxiliarists . According to the National Security Act of 1947 (61 Stat . 502), which created the USAF: Section 9062 of Title 10 US Code defines

905-528: A Luftwaffe airfield at Saint-Omer near Calais, France. On October 13, 1944, a Thunderbolt from 9th Air Force damaged the German Torpedoboot Ausland 38 (formerly the Italian 750 ton torpedo boat Spada) so badly near Trieste with gunfire alone that the ship was scuttled. The Vought F4U Corsair was built around the same Pratt & Whitney R-2800 Double Wasp engine as the Thunderbolt, but for

1086-600: A Red Cross flag painted on at least one funnel. The previous day the Captain of the Cap Arcona refused to take any more inmates on board. On return to shore in longboats they were gunned down by Hitler Jugend , SS Guards and German Marines . Of an estimated 14,500 victims in the area two days earlier only 1,450 survived. The Hawker Tempest was a development of the Typhoon using the thin wing with an aerofoil developed by NACA and

1267-664: A Soviet boycott of the United Nations , a vote was carried without Soviet veto, to intervene in support of the South. Most readily available were U.S. and British Commonwealth forces occupying Japan and the Pacific fleets. The first arrivals were fighter-bombers, which helped to repulse the Northern attack on the vital port of Pusan , the last small territory held by the South. Some strategists felt that air and battleship strikes alone could halt

1448-426: A broader dimension of time or space than do tactics; they provide the means by which tactical successes are exploited to achieve strategic and operational objectives. Tactical Level Command and Control is where individual battles and engagements are fought. The tactical level of war deals with how forces are employed, and the specifics of how engagements are conducted and targets attacked. The goal of tactical level C2

1629-438: A cleanup plan for drinking water around Tucson, Arizona after the region's groundwater was contaminated by PFAS runoff from nearby Air Force bases. The United States Air Force has been involved in many wars, conflicts and operations using military air operations. The USAF possesses the lineage and heritage of its predecessor organizations, which played a pivotal role in U.S. military operations since 1907: In addition since

1810-452: A commander in planning, directing, coordinating, and controlling forces and operations in the accomplishment of the mission" (JP 1-02). This core function includes all of the C2-related capabilities and activities associated with air, cyberspace, nuclear, and agile combat support operations to achieve strategic, operational, and tactical objectives. At the strategic level command and control,

1991-573: A crew of three, and its payload was just 1,200 lb (540 kg) of bombs. The Blenheim suffered disastrous losses over France in 1939 when it encountered Messerschmitt Bf 109s , and light bombers were quickly withdrawn. In contrast, the Vought F4U Corsair fighter —which entered service in December 1942—had in common with its eventual U.S. Navy stablemate, the Grumman F6F Hellcat and

2172-617: A dive bomber almost as fast as the Mustang itself. By April 1943 USAAF Apaches were in Morocco supporting Operation Torch , and they continued bombing trains and gun emplacements northwards through Italy. When Soviet-backed North Korea attacked South Korea on June 25, 1950, their forces quickly routed the South Korean army which lacked tanks, anti-tank and heavy artillery. Its Air Force had 22 planes, none of which were fighters, or jets. During

2353-601: A fighter bomber, where one tried skip-bombing a 1,000 lb (450 kg) bomb through the door of Field Marshal Günther von Kluge 's OB West HQ. A Lightning squadron also killed Admiral Isoroku Yamamoto over Bougainville in the Pacific acting on an Ultra intercept. The Republic P-47 Thunderbolt was a larger, evolutionary development of the P-43/P-44 fighter undertaken after the United States Army Air Forces observed Messerschmitt Bf 109s performing in

2534-791: A flag stuck into a shingle beach. Both WW1 fighter bombers were used with novice and experienced pilots. The best results were achieved with a vertical dive into the wind using the Aldis Sight to align the aircraft. But they were not considered good enough to justify the expected casualty rate. When war broke out in Europe, Western Allied Air Forces employed light twin-engined bombers in the tactical role for low-level attacks. These were found to be extremely vulnerable both to ground fire and to single-engine fighters. The German and Japanese Air Forces had chosen dive bombers which were similarly vulnerable. The Ilyushin Il-2

2715-894: A force multiplier. It allows air assets to more rapidly reach any trouble spot around the world with less dependence on forward staging bases or overflight/landing clearances. Air refueling significantly expands the options available to a commander by increasing the range, payload, persistence, and flexibility of receiver aircraft. Aeromedical evacuation is "the movement of patients under medical supervision to and between medical treatment facilities by air transportation" (JP 1-02). JP 4-02, Health Service Support, further defines it as "the fixed wing movement of regulated casualties to and between medical treatment facilities, using organic and/or contracted mobility airframes, with aircrew trained explicitly for this mission." Aeromedical evacuation forces can operate as far forward as fixed-wing aircraft are able to conduct airland operations. Global precision attack

2896-465: A larger airframe than the nimble Hurricane. At the prototype stage, there were problems with the new engines and stability of the aircraft itself, which led the Minister of Aircraft Production , Lord Beaverbrook to decree that production must focus on Spitfires and Hurricanes. The Typhoon disappointed as a fighter, especially at altitude but found its true niche as a fighter bomber from September 1942. It

3077-780: A last-ditch attempt to destroy Allied planes on the ground in support of the Battle of the Bulge . Allied fighter aircraft and fighter-bomber losses were downplayed, at the time. Seventeen airfields were targeted, of which seven lost many aircraft. The surprise was complete as the few Ultra intercepts had not been understood. At the worst hit, the Canadian base at Eindhoven , 26 Typhoons and 6 Spitfires were destroyed and another 30 Typhoons damaged. In total, 305 aircraft, mostly fighters, and fighter-bombers were destroyed and another 190 damaged. The Luftwaffe lost 143 pilots killed, 71 captured and 20 wounded, making

3258-475: A later version could carry eight rockets or 4,000 lb (1,800 kg) of bombs. The massive, powerful 18-cylinder Double Wasp engine weighed almost a ton—half as much again as the V12 Rolls-Royce Merlin and twice as much as the 9-cylinder Bristol Mercury that powered some heavy fighters . Increased engine power meant that many existing fighter designs could carry useful bomb loads, and adapt to

3439-526: A more powerful version of the Napier Sabre engine, giving a top speed of 432 miles per hour (695 km/h). At a low level, it was faster than any other Allied or German aircraft, but slower than the Spitfire above 22,000 ft (6,700 m). Fitted with four 20mm cannon it was a formidable fighter, respected even by Messerschmitt Me 262 jet fighter pilots as their most dangerous opponent. At its debut over

3620-520: A nation state, or non-state/transnational actor. The Air Force maintains and presents credible deterrent capabilities through successful visible demonstrations and exercises that assure allies, dissuade proliferation, deter potential adversaries from actions that threaten US national security or the populations, and deploy military forces of the US, its allies, and friends. Nuclear strike is the ability of nuclear forces to rapidly and accurately strike targets which

Air Interdiction is defined as "air operations conducted to divert, disrupt, delay, or destroy the enemy's military potential before it can be brought to bear effectively against friendly forces, or to otherwise achieve JFC objectives. Air Interdiction is conducted at such distance from friendly forces that detailed integration of each air mission with

3982-483: A rapid cessation of hostilities. Post-conflict, regeneration of a credible nuclear deterrent capability will deter further aggression. The Air Force may present a credible force posture in either the Continental United States , within a theater of operations, or both to effectively deter the range of potential adversaries envisioned in the 21st century. This requires the ability to engage targets globally using

4163-431: A redesign of the fuselage to conform to the area rule , giving it a characteristic "wasp waist". The F-105's reworked air intake was designed with a unique forward-swept shape, which was derived from Antonio Ferri 's work on the proposed Republic XF-103 ramjet-powered interceptor. In combination with the distinctive forward-swept variable-geometry air intakes, which regulated airflow to the engine at supersonic speeds, and

4344-747: A sharp reduction in flight hours for crew training since 2005 and the Deputy Chief of Staff for Manpower and Personnel directing Airmen's Time Assessments. On 5 June 2008, Secretary of Defense Robert Gates accepted the resignations of both the Secretary of the Air Force , Michael Wynne , and the Chief of Staff of the Air Force , General T. Michael Moseley . In his decision to fire both men Gates cited "systemic issues associated with... declining Air Force nuclear mission focus and performance". Left unmentioned by Gates

4525-587: A single nuclear weapon internally. First flown in 1955, the Thunderchief entered service in 1958. The single-engine F-105 could deliver a bomb load greater than some American heavy bombers of World War II such as the Boeing B-17 Flying Fortress and Consolidated B-24 Liberator . The F-105 was one of the primary attack aircraft of the Vietnam War, with over 20,000 Thunderchief sorties flown. Out of

4706-484: A single, internally carried nuclear bomb. The emphasis was placed on low-altitude speed and flight characteristics, range, and payload. The aircraft would be fitted with a large engine, and a relatively small wing with a high wing loading for a stable ride at low altitudes, and less drag at supersonic speeds. Traditional fighter attributes such as maneuverability were a secondary consideration. During April 1952, Republic made its contractor proposal, which contained many of

4887-693: A smoke generator, briefly flew with the United States Air Force Thunderbirds demonstration team. After only six shows, a fatal accident from overstressing the airframe led to the reintroduction of the F-100 Super Sabre. By 1964, the F-105B was relegated to USAF Air National Guard (ANG) squadrons. It was replaced in frontline service by the definitive F-105D whose advanced NASARR R-14A radar and AN/ASG-19 Thunderstick fire-control system gave it all-weather capability. The R-14A radar also added

5068-482: A specific prescribed role. Engine power grew dramatically during the early period of the war, roughly doubling between 1939 and 1943. The Bristol Blenheim , a typical light bomber of the opening stages of the war, was originally designed in 1934 as a fast civil transport to meet a challenge by Lord Rothermere , owner of the Daily Mail . It had two Bristol Mercury XV radial engines of 920 hp (690 kW) each,

5249-513: A stable aircraft like the Typhoon. But soft targets were simpler. When the 51st Highland Division moved to block German panzers reaching Antwerp in the Battle of the Bulge Tommy Macpherson saw a half-track full of SS soldiers. All were uninjured, powerful men over 6 ft (180 cm) tall. All were dead, killed by the air blast from a Typhoon rocket. The Bristol Beaufighter was a long-range twin-engine heavy fighter derived from

5430-448: A strong focus on the improvement of Basic Military Training (BMT) for enlisted personnel. While the intense training has become longer, it also has shifted to include a deployment phase. This deployment phase, now called the BEAST, places the trainees in a simulated combat environment that they may experience once they deploy. While the trainees do tackle the massive obstacle courses along with

5611-534: A target tug role, where it could match the speed of the German bombers whilst towing a drone. In 1934, the British Air Ministry called for a carrier aircraft that could combine the roles of the dive bomber and fighter, to save limited space on small carriers. The Blackburn Skua was not expected to encounter land-based fighters but was to intercept long-range bombers attacking the fleet and also to sink ships. As

5792-528: A two-seat Wild Weasel version was later developed for the specialized Suppression of Enemy Air Defenses (SEAD) role against surface-to-air missile sites. The F-105 was commonly known as the "Thud" by its crews. As a follow-on to the Mach 1 capable North American F-100 Super Sabre , the F-105 was also armed with missiles and a rotary cannon; however, its design was tailored to high-speed low-altitude penetration carrying

5973-627: A two-seater, it could not fight the Messerschmitt Bf 109 on equal terms. But the second seat carried a radio operator with a homing device that could find the carrier even when it had moved, in foul North Sea weather. It achieved one of the first kills of the war, when three from HMS Ark Royal downed a German Dornier Do 18 flying boat over the North Sea. On April 10, 1940, 16 Skuas operating from RNAS Hatston in Orkney under Commander William Lucy sank

6154-510: A variety of methods; therefore, the Air Force should possess the ability to induct, train, assign, educate and exercise individuals and units to rapidly and effectively execute missions that support US NDO objectives. Finally, the Air Force regularly exercises and evaluates all aspects of nuclear operations to ensure high levels of performance. Nuclear surety ensures the safety, security and effectiveness of nuclear operations. Because of their political and military importance, destructive power, and

6335-421: A very fast radial engine fighter over France. First thought to be captured French Curtiss 75 Mohawks , they turned out to be Focke-Wulf Fw 190s , slightly faster and more heavily armed than the current Spitfire V. Kurt Tank had designed the aircraft when the Spitfire and Bf 109 were the fastest fighters flying; he called them racehorses, fast but fragile. As a former World War I cavalryman, Tank chose to design

6516-443: A warhorse. With a BMW 801 radial engine , wide-set undercarriage, and two 20mm cannons as well as machine guns it became a better fighter-bomber than either of the pure fighters. By mid-1942, the first of these "Jagdbombers" (literally "fighter" or "hunter" bomber, known for short as "Jabos") was operating over Kent . On October 31, 60 Fw 190s bombed Canterbury with only one aircraft lost, killing 32 civilians and injuring 116, in

OCA is the preferred method of countering air and missile threats since it attempts to defeat the enemy closer to its source and typically enjoys the initiative. OCA comprises attack operations, sweep, escort, and suppression/destruction of enemy air defense. Defensive Counter-Air (DCA)

7783-899: Is one of the eight uniformed services of the United States . Originally created on 1 August 1907, as a part of the United States Army Signal Corps , the USAF was established as a separate branch of the United States Armed Forces in 1947 with the enactment of the National Security Act of 1947 . It is the second youngest branch of the United States Armed Forces and the fourth in order of precedence .

The origins of the United States Air Force can be traced back to the Union Army Balloon Corps of the American Civil War . The Union Balloon Corps, established by aeronaut Thaddeus S. C. Lowe , provided aerial reconnaissance for the Union Army . This early use of balloons for military purposes marked

8507-509: The 8th Tactical Fighter Wing converting from 1963. Like the F-105B, the F-105D's early career was plagued with maintenance problems and in-flight failures. The origins of the nickname "Thud" were obscure; some claim that it stood for the sound of an F-105 crashing into the ground. The entire F-105D fleet was grounded in December 1961 and then again in June 1962. Many of the issues were worked out during

8688-414: The Battle of Britain . It was a massive aircraft built around the powerful Pratt & Whitney R-2800 Double Wasp engine and weighed up to eight tons with ordnance. The P-47 was twice as heavy and had four times the fuselage size of a Spitfire. Armed with eight .50 in (12.7 mm) M2 Browning machine guns it could outshoot any enemy fighter, and as a fighter-bomber, it could carry half the bomb load of

By late 1942 the Beaufighter was also capable of carrying torpedoes or rockets. The main user was RAF Coastal Command although it was also used in the Royal Australian Air Force with some aircraft assembled in Australia and by

9231-615: The German cruiser Königsberg which was tied to a mole in Bergen harbour. The Germans recorded five hits or near misses and as the ship started to sink, electric power failed, dooming the ship. The German cruiser Köln had departed during the night. With the failing of the Hawker Henley and the gradual fading of the Hawker Hurricane 's performance compared to the latest German fighters, it

9412-600: The Gestapo HQ in Oslo was attacked by four de Havilland Mosquitoes , which had flown over the North Sea below 100 ft (30 m) by dead reckoning navigation from RAF Leuchars , Scotland, carrying four 500 lb (230 kg) bombs each. The next day the RAF unveiled its new fast bomber. On December 31, 1944, the same aircraft was used against the same target, this time from RAF Peterhead in Scotland, flying high and diving onto

9593-488: The McDonnell Douglas F-4 Phantom II and the swing-wing General Dynamics F-111 Aardvark . However, the "Wild Weasel" variants of the F-105 remained in service until early 1984, at which point they were replaced by the specialized F-4G "Wild Weasel V" . Republic Aviation started work on what would become the Thunderchief during 1951. It was conceived of as an internal project to produce a replacement for

9774-603: The Normandy Beaches on D-Day +2, Tempests shot down three German fighters, without loss. Tempests supported the ambitious attempt to capture the bridge at Arnhem in Operation Market Garden in mid-September 1944. David C. Fairbanks , an American who joined the Royal Canadian Air Force was the top Tempest ace with 12 victories including an Arado Ar 234 jet bomber. General Henry H. Arnold , Chief of

An example of a modern purpose-designed fighter bomber is the Sukhoi Su-34 . United States Air Force The United States Air Force ( USAF ) is the air service branch of the United States Armed Forces , and

10136-623: The North American F-86 Sabre was rushed to Korea to combat the MiG-15s. There is much debate as to which was the better fighter. Recent research suggests a 13-10 advantage to the Sabre against Russian pilots, but the US pilots were mostly WWII veterans whilst the Russians were often “volunteers” with only a few hours aloft. The Australians converted from Mustangs to Gloster Meteor fighter-bombers,

10317-488: The RF-84F Thunderflash , which first used the characteristic wing-root air intakes to make room for cameras in the nose section. The design team led by Alexander Kartveli examined some 108 configurations before settling on a large, single-engine AP-63FBX (Advanced Project 63 Fighter Bomber, Experimental), specifically AP-63-31. The new aircraft was intended primarily for supersonic, low altitude penetration to deliver

10498-416: The Royal Australian Air Force soon also flew across from Japan. Vought F4U Corsairs and Hawker Sea Furys from U.S., British and Australian carriers in the Yellow Sea and later from Korean airfields, also attacked the Pusan perimeter. The Sea Fury, a development of the Hawker Tempest had a Bristol Centaurus engine of 2,480 hp (1,850 kW) giving a 485 mph (781 km/h) top speed, one of

10679-437: The Soviet -built S-75 Dvina ( NATO reporting name : SA-2 Guideline ) surface-to-air missiles. Two Wild Weasel pilots were awarded the Medal of Honor for attacking North Vietnamese surface-to-air missile sites, with one shooting down two MiG-17s the same day. The dangerous missions often required them to be the "first in, last out", suppressing enemy air defenses while strike aircraft accomplished their missions and then left

10860-431: The Tactical Air Command 's 335th Tactical Fighter Squadron of the 4th Tactical Fighter Wing in August 1958, although the squadron did not become fully operational until 1959. On 11 December 1959, an F-105B piloted by Brig Gen Joseph Moore (commander of the 4th Tactical Fighter Wing) set a world record of 1,216.48 miles per hour (1,958 km/h) over a 62 miles (100 km) circuit. Difficulties with its avionics and

11041-428: The Thanh Hoa Bridge , nicknamed "Dragon's Jaw". The next day, enemy MiGs were encountered during a second run upon the bridge; a total of eight MiG-17s faced 46 F-105s escorted by a MiGCAP flight of 21 F-100 Super Sabres. The MiG-17s evaded the escorts using altitude and cloud cover, instead focusing upon the bomb-laden Thunderchiefs. Two Thunderchiefs were lost to the MiG-17s; a third, thought to be lost to ground fire,

11222-427: The U.S. Navy . Difficulties with carrier landings meant that the first aircraft were used by the United States Marine Corps from Henderson Field, Guadalcanal from February 12, 1943. In its first combat action, the following day over Kahili airfield two Corsairs and eight other aircraft were lost when attacked by 50 Mitsubishi A6M Zeros . This became known as the St Valentine's Day massacre. Despite this initiation

11403-444: The USAAF . Over 30 Beaufighters flying from RAF Dallachy in Scotland from Australian, British, Canadian, and New Zealand squadrons attacked the German destroyer Z33 sheltering in Førde Fjord Norway. They were escorted by only 10 to 12 North American P-51 Mustangs . German destroyers escorted convoys of Swedish iron ore, which in winter were forced to creep along the Atlantic Coast by night, hiding deep inside fjords by day. Z33

11584-403: The United States Army Air Forces , urged the adoption of the Mosquito by the U.S. but was overruled by those who felt that the as yet untried Lockheed P-38 Lightning also twin-engined, could fulfill the same role. Although Lightning got its name from the RAF, the British eventually rejected it. Too slow and cumbersome to match Bf 109s as an escort fighter over Germany, it did fly over Normandy as

11765-449: The 1950s and 1960s, as new jet engines dramatically improved the power of even the smallest fighter designs. Many aircraft initially designed as fighters or interceptors found themselves in the fighter-bomber role at some point in their career. Notable among these is the Lockheed F-104 Starfighter , first designed as a high-performance day fighter and then adapted to the nuclear strike role for European use. Other U.S. examples include

11946-433: The 230 mph (370 km/h) range. The spoilers provided good roll control at all speeds and the distinctive four-petal airbrakes (which also opened slightly when the afterburner was engaged to allow for the larger flow of exhaust gases) were highly effective even at supersonic speeds. Loss of control due to a spin or complications of adverse yaw required deliberate effort from the pilot and spontaneous spin recovery

12127-437: The 833 produced, 382 aircraft were lost, including 62 operational (non-combat) losses. Although less agile than smaller MiG fighters, USAF F-105s were credited with 27.5 kills. During the conflict, the single-seat F-105D was the primary aircraft delivering heavy bomb loads against the various military targets. Meanwhile, the two-seat F-105F and F-105G Wild Weasel variants became the first dedicated SEAD platforms, fighting against

12308-428: The Air Force and the Chief of Staff of the Air Force retain administrative authority over their members. Along with conducting independent air operations, the United States Air Force provides air support for land and naval forces and aids in the recovery of troops in the field. As of 2020 , the service operates approximately 5,500 military aircraft and approximately 400 ICBMs . The world's largest air force, it has

12489-411: The Air Force is the Chief of Staff of the Air Force , who exercises supervision over Air Force units and serves as one of the Joint Chiefs of Staff . As directed by the Secretary of Defense and Secretary of the Air Force, certain Air Force components are assigned to unified combatant commands . Combatant commanders are delegated operational authority of the forces assigned to them, while the Secretary of

12670-410: The Air Force states as global vigilance, global reach, and global power. Air superiority is "that degree of dominance in the air battle of one force over another which permits the conduct of operations by the former and its related land, sea, air, and special operations forces at a given time and place without prohibitive interference by the opposing force" (JP 1-02). Offensive Counter-Air (OCA)

12851-422: The Air Force's readiness to carry out the nuclear strike operations mission as well as from specific actions taken to assure allies as a part of extended deterrence. Dissuading others from acquiring or proliferating WMD and delivering them contributes to promoting security and is also an integral part of this mission. Moreover, different deterrence strategies are required to deter various adversaries, whether they are

13032-535: The BEAST, the other portions include defending and protecting their base of operations, forming a structure of leadership, directing search and recovery, and basic self aid buddy care. During this event, the Military Training Instructors (MTI) act as mentors and opposing forces in a deployment exercise. In November 2022, the USAF announced that it will discontinue BEAST and replace it with another deployment training program called PACER FORGE. In 2007,

13213-716: The Corsair soon proved to be an effective fighter bomber, mostly flown by the Marine Corps, but also by the United States Navy , Fleet Air Arm and Royal New Zealand Air Force in the Pacific theater. When the British Purchasing Commission invited James H. Kindelberger , President of North American Aviation , to assemble the Curtiss P-40 Warhawk in an underutilized plant, he promised a better fighter on

13394-707: The Dien Ben Phu munitions storage depot and the Lang Chi munitions factory west of Hanoi. One was shot down and three were damaged by SA-2 missiles. After two days, President Johnson gave the order to attack all known SA-2 positions which had been discovered outside the 30-mile exclusion zone. On the morning of 27 July, 48 F-105s participated in the Operation Spring High attack. But the Vietnamese knew U.S. aircraft were coming and set up many 23mm and 37mm anti-aircraft guns at

13575-564: The F-100F. The first of these aircraft flew on 15 January 1966 and they began arriving in Southeast Asia in May, flying their first mission on 6 June 1966, with five assigned to the 13th TFS at Korat RTAFB and six more to the 354th TFS at Takhli RTAFB. In a typical early mission, a single EF-105F would accompany one or two flights of F-105Ds to provide protection from enemy ground fire. While this strategy

13756-497: The F-105's responsive controls, strong performance at high speed and low altitude, and its outfit of electronics won over some pilots. For some, "Thud" was a term of endearment; retroactively the RF-84F Thunderflash became known as "Thud's Mother". F-105 pilot Colonel Jack Broughton said of the nickname: "The Thud has justified herself, and the name that was originally spoken with a sneer has become one of utmost respect through

13937-610: The F-105C trainer variant were added to the procurement plan in June 1956, before being canceled during 1957. The RF-105 reconnaissance variant was canceled in July 1956. The first production F-105B was accepted by the USAF on 27 May 1957. In June 1957, Republic Aviation requested that the F-105 be named Thunderchief , continuing the sequence of the company's Thunder-named aircraft: P-47 Thunderbolt , F-84 Thunderjet , and F-84F Thunderstreak. The USAF made this name official one month later. To fulfill

14118-514: The F-105D featured vertical-tape instrument displays for adverse weather operation. The ability to carry the TX-43 nuclear weapon was also added. On account of these myriad changes, Republic noted the difficulty of using the same production line as had been used for the F-105B; production times would also be extended from 144 days to 214 days. Development of the RF-105 reconnaissance model was restarted during

14299-491: The F-105D, this model was 31 inches (79 cm) longer to provide room for the rear cockpit; otherwise, the aircraft had similar flight performance to the preceding F-105D. A total of 833 F-105s were completed before production ended in 1964. The F-105 had been designed for a short nuclear campaign, leading to shortcomings that became evident in a lengthy conventional war, such as a poor hydraulics layout and fuel tanks that were not self-sealing . Subsequent upgrades improved

14480-556: The F-105Ds was named Memphis Belle II after the famed World War II B-17 . In spite of a troubled early service life, the F-105 became the dominant attack aircraft early in the Vietnam War . The F-105 could carry more than twice the bomb load farther and faster than the F-100, which was used mostly in South Vietnam. In a foreshadowing of its Wild Weasel role, the first F-105D combat mission of

14661-635: The F-105F. It bounced voice communications over the radio channel back out after a delay, resulting in an obnoxious garble. However, the first time the Combat Martin was used, the US National Security Agency (NSA), in charge of US strategic signals intelligence , ordered the Air Force to cease and desist immediately, since the NSA believed that the intelligence obtained by monitoring the channels outweighed

14842-541: The French and Belgian coasts, targeting mostly oil and gas works. Losses were heavy, often more than the numbers of enemy fighters destroyed. By May 1942 Hurricane IICs with 40-imperial-gallon (180 L) drop tanks were intruding at night over France. On the night of May 4–5, Czech pilot Karel Kuttelwascher flying from RAF Tangmere with No 1 Squadron shot down three Dornier Do 17s as they slowed to land at Saint-André-de-Bohon after raiding England. On September 25, 1942,

15023-580: The Germans, only 10 were found to be due to rocket-firing Typhoons. At Mortain, where the German counter-offensive Operation Lüttich came within 2 miles (3.2 km) of cutting through US forces to Avranches , Typhoons destroyed 9 of 46 tanks lost but were more effective against unarmoured vehicles and troops and cause the armoured vehicles to seek cover. General Dwight D. Eisenhower , the Supreme Allied Commander, said "The chief credit in smashing

15204-445: The J75 engine, this redesign enabled the F-105B to attain Mach 2.15. During March 1956, the USAF placed a further order for 65 F-105Bs and 17 RF-105Bs. In order to conduct the nuclear mission, an MA-8 fire control system , AN/APG-31 ranging radar , and K-19 gunsight to allow for toss bombing were integrated. On 26 May 1956, the first pre-production YF-105B made its maiden flight. Five of

15385-460: The MA-8 fire-control system were experienced early on; typically the F-105 required 150 hours of maintenance for each flying hour. Most of these problems were addressed under Project Optimize . The lack of spares resulted in the entire F-105B fleet being briefly grounded in 1960. In 1964, modified F-105Bs with ballast replacing the cannon, fuselage and wing reinforcement for aerobatics, and the addition of

15566-545: The Mosquito I am yellow and green with envy. (The British) have the geniuses and we have the nincompoops.” Initially used for high-level photo-reconnaissance, the Mosquito was adapted to precision bombing, night fighter, and fighter bomber roles. It was built in Canada and Australia as well as the UK. Fitted with a British Army Ordnance QF 6 pounder (57 mm) gun it could sink U-boats found on

15747-770: The Navy , and the newly created Department of the Air Force. Prior to 1947, the responsibility for military aviation was shared between the Army Air Forces and its predecessor organizations (for land-based operations), the Navy (for sea-based operations from aircraft carriers and amphibious aircraft), and the Marine Corps (for close air support of Marine Corps operations). The 1940s proved to be important for military aviation in other ways as well. In 1947, Air Force Captain Chuck Yeager broke

15928-457: The ROMO. The purpose of nuclear deterrence operations (NDO) is to operate, maintain, and secure nuclear forces to achieve an assured capability to deter an adversary from taking action against vital US interests. In the event deterrence fails, the US should be able to appropriately respond with nuclear options. The sub-elements of this function are: Assure/Dissuade/Deter is a mission set derived from

16109-535: The Republic F-84 Thunderjet and F-84F Thunderstreak, nicknamed "Hog" and "Super Hog", respectively. According to F-105 pilots and crews, the "Thud" nickname was inspired by the character "Chief Thunderthud" from the Howdy Doody television series. The aircraft's offensive capabilities were sarcastically referred to as a "Triple Threat"—it could bomb you, strafe you, or fall on you. Positive aspects, such as

16290-543: The US determines national or multinational security objectives and guidance, and develops and uses national resources to accomplish these objectives. These national objectives in turn provide the direction for developing overall military objectives, which are used to develop the objectives and strategy for each theater. At the operational level command and control, campaigns and major operations are planned, conducted, sustained, and assessed to accomplish strategic goals within theaters or areas of operations. These activities imply

16471-519: The USAF began operating two-seat North American F-100F Super Sabres specially equipped for Suppression of Enemy Air Defenses (SEAD) missions in Vietnam. Nicknamed the Wild Weasel, these aircraft achieved a number of victories against North Vietnamese surface-to-air missile radars. The second crew member was a Navigator trained as an Electronic Warfare Officer (EWO) to decipher sensor information and guide

16652-510: The USAF dwarfs all other U.S. and allied air components, it often provides support for allied forces in conflicts to which the United States is otherwise not involved, such as the 2013 French campaign in Mali . The USAF has also taken part in numerous humanitarian operations. Some of the more major ones include the following: The culture of the United States Air Force is primarily driven by pilots, at first those piloting bombers (driven originally by

16833-464: The USAF established the nuclear-focused Air Force Global Strike Command on 24 October 2008, which later assumed control of all USAF bomber aircraft. On 26 June 2009, the USAF released a force structure plan that cut fighter aircraft and shifted resources to better support nuclear, irregular and information warfare. On 23 July 2009, The USAF released their Unmanned Aerial System (UAS) Flight Plan, detailing Air Force UAS plans through 2047. One third of

17014-509: The USAF undertook a Reduction-in-Force (RIF). Because of budget constraints, the USAF planned to reduce the service's size from 360,000 active duty personnel to 316,000. The size of the active duty force in 2007 was roughly 64% of that of what the USAF was at the end of the first Gulf War in 1991. However, the reduction was ended at approximately 330,000 personnel in 2008 in order to meet the demand signal of combatant commanders and associated mission requirements. These same constraints have seen

17195-590: The USAF's requirement for an all-weather attack aircraft, Republic proposed the F-105D variant during 1957. This version featured an enlarged nose and radome housing the AN/ASG-19 Thunderstick bombing/navigation system. The AN/ASG-19 was designed around the Autonetics R-14A radar, which operated in both air-to-air and air-to-ground modes, and the AN/APN-131 Doppler navigation radar. In the cockpit,

17376-586: The United Kingdom from September to December 1940. A larger fighter-bomber campaign was conducted against the UK from March 1942 until June 1943. These operations were successful in tying down Allied resources at a relatively low cost to the Luftwaffe, but the British Government regarded the campaign as a nuisance given the small scale of the individual raids. In August 1941, RAF pilots reported encountering

17557-516: The Weapon System designation WS-306A . On 22 October 1955, the YF-105A prototype made its maiden flight . After 22 hours of flight time, the prototype was returned to the factory for repairs after sustaining major damage. The second YF-105A made its first flight on 28 January 1956. Despite being powered by a less potent J57-P-25 engine with 15,000 pounds-force (67  kN ) of afterburning thrust,

17738-471: The Wild Weasel III standard. In an effort to thwart MiG attacks, several F-105Fs were also fitted with Hallicrafters QRC-128 communication jamming system under project Combat Martin . The North Vietnamese interceptor force followed Soviet air-defense doctrine, with pilots under rigid direction of ground controllers over radio links. The QRC-128, nicknamed "Colonel Computer", filled up the rear cockpit of

17919-718: The World's Aircraft 1969-70 General characteristics Performance Armament Avionics Related development Aircraft of comparable role, configuration, and era Related lists Fighter-bomber Although still used, the term fighter-bomber has less significance since the introduction of rockets and guided missiles into aerial warfare . Modern aircraft with similar duties are now typically called multirole combat aircraft or strike fighters . Prior to World War II , general limitations in available engine and aeronautical technology required that each proposed military aircraft have its design tailored to

18100-526: The ability to fulfill their primary mission. Rapid Global Mobility is essential to virtually every military operation, allowing forces to reach foreign or domestic destinations quickly, thus seizing the initiative through speed and surprise. Airlift is "operations to transport and deliver forces and materiel through the air in support of strategic, operational, or tactical objectives" (Annex 3–17, Air Mobility Operations). The rapid and flexible options afforded by airlift allow military forces and national leaders

18281-407: The ability to integrate, evaluate, and interpret information from available sources to create a finished intelligence product for presentation or dissemination to enable increased situational awareness. Dissemination and integration is "the delivery of intelligence to users in a suitable form and the application of the intelligence to appropriate missions, tasks, and functions" (JP 2-01). It provides

18462-425: The ability to present information and intelligence products across the ROMO enabling understanding of the operational environment to military and national decision-makers. Rapid global mobility is the timely deployment, employment, sustainment, augmentation, and redeployment of military forces and capabilities across the ROMO. It provides joint military forces the capability to move from place to place while retaining

18643-455: The ability to respond and operate in a variety of situations and time frames. The global reach capability of airlift provides the ability to apply US power worldwide by delivering forces to crisis locations. It serves as a US presence that demonstrates resolve and compassion in humanitarian crisis. Air refueling is "the refueling of an aircraft in flight by another aircraft" (JP 1-02). Air refueling extends presence, increases range, and serves as

18824-493: The air fraternity". The rear cockpits of several two-seat F-105Fs were modified under project Commando Nail with an R-14A radar and a radar scope that offered high resolution. These aircraft were used for all-weather and night low-level strikes against especially dangerous targets by a unit from the 13th Tactical Fighter Squadron (1966–1975) dubbed "Ryan's Raiders" starting in April 1967. Some of these aircraft were later converted to

19005-433: The area. When the Thunderchief entered service it was the largest single-seat, single-engine combat aircraft in history, weighing approximately 50,000 pounds (23,000  kg ). It could exceed the speed of sound at sea level and reach Mach 2 at high altitude. The F-105 could carry up to 14,000 lb (6,400 kg) of bombs and missiles. The Thunderchief was later replaced as a strike aircraft over North Vietnam by both

19186-430: The beginning of modern aerial warfare and set the stage for the development of the United States Air Force. The U.S. War Department created the first antecedent of the U.S. Air Force, as a part of the U.S. Army, on 1 August 1907, which through a succession of changes of organization, titles, and missions advanced toward eventual independence 40 years later. In World War II , almost 68,000 U.S. airmen died helping to win

19367-527: The benefits of jamming them. Experience in Vietnam demonstrated the need for a better visual and blind bombing capability. In March 1968, the Air Force ordered development of an upgraded bombing/navigation system, incorporating a Singer-General Precision inertial navigation system , improvements to the AN/APN-131 navigation radar, and solid-state circuitry for the R-14A radar, which was redesignated R-14K. Furthermore,

19548-469: The building. In February 1941 the Mosquito with two Rolls-Royce Merlin engines and a streamlined wooden fuselage achieved 392 mph (631 km/h), 30 mph (48 km/h) faster than the current Spitfire. It was used on all kinds of missions, including silencing Hermann Göring 's Berlin Nazi anniversary broadcast on January 20, 1943, leading him to tell Erhard Milch, Air Inspector General that “when I see

19729-411: The cost of 17 aircraft lost to enemy fighters (North Vietnamese pilots claimed to have shot down an additional 23 F-105s but none have been confirmed by USAF). All victories were against MiG-17s. Of these 24.5 were shot down with cannon fire (one victory was shared with an F-4), and three with AIM-9 Sidewinder missiles. One F-105F is unofficially credited with downing three MiGs—one by air-to-air missile,

19910-658: The cost of six aircraft and five pilots. In December 1966, the Vietnam People's Air Force (VPAF)'s MiG-21 pilots of the 921st Regiment claimed to have downed 14 F-105s without any losses. On a typical combat mission into North Vietnam, the F-105D carried two 450 US gal (1,700 L) wing-mounted fuel tanks, a 390 US gal (1,500 L) fuel tank in the bomb bay, and five 1,000 lb (450 kg) or six 750 lb (340 kg) bombs, and required inflight refueling going to and sometimes returning from Hanoi 700 mi (1,100 km) distant. F-105s flying in

20091-529: The definitive Wild Weasel Thunderchief, the F-105G. The F-105G incorporated a considerable amount of new SEAD-specific avionics, including an upgraded Radar Homing and Warning (RHAW) system which required a redesign of the wingtips. To free outboard hardpoints for additional weapons, the Westinghouse AN/ALQ-105 electronic countermeasures were permanently installed in two long blisters on the underside of

20272-594: The destruction of the Ban Ken bridge in Laos . In early 1965 additional F-105 squadrons were deployed to Korat and Takhli air bases in Thailand. At the start of Operation Rolling Thunder in March 1965, large numbers of F-105Ds were shipped to these bases to participate in intense bombing missions. On 3 April 1965, a total of 79 aircraft, including 45 F-105 Thunderchiefs, were sent against

20453-407: The digital AN/ARN-92 long-range navigation receiver replaced the problematic AN/ARN-85 receiver. The additional avionics were housed in a long, raised dorsal spine. The modified bombing/navigation system was known as Thunderstick II . F-105s with this system could achieve a bombing circular error of probability (CEP) of 50 feet (15 m) from an altitude of 15,000 ft (4,600 m). Although

20634-422: The enemy holds dear in a devastating manner. If a crisis occurs, rapid generation and, if necessary, deployment of nuclear strike capabilities will demonstrate US resolve and may prompt an adversary to alter the course of action deemed threatening to our national interest. Should deterrence fail, the President may authorize a precise, tailored response to terminate the conflict at the lowest possible level and lead to

20815-477: The enemy's spearhead, however, must go to the rocket-firing Typhoon aircraft of the Second Tactical Air Force . The result of the strafing was that the enemy attack was effectively brought to a halt, and a threat was turned into a great victory". The disparity between claims and actual destruction at about 25-1 owed much to the difficulty of hitting a fast-moving tank with an unguided rocket, even from

20996-489: The entire cadet wing, the superintendent and commandant of cadets of the USAFA, a representative of Republic Aircraft, members of the press, among others. To conclude the ceremony, a flight of four F-105s from McConnell AFB were to fly over in formation at 1,000 feet above the ground and then fly over singly at 250 feet. The formation portion happened as planned. But the flight leader, Lt Col James "Black Matt" Matthews, came back for

21177-531: The equipment to launch AGM-12 Bullpup air-to-ground missiles. In June 1961, an F-105D delivered 15,430 lb (7,000 kg) of conventional bombs during a USAF test—at the time, a record for a single-engine aircraft with a payload three times heavier than American four-engine heavy bombers of World War II, such as the Boeing B-17 Flying Fortress and the Consolidated B-24 Liberator , though aerial refueling would be required for long missions. One of

21358-482: The fastest piston-engined aircraft ever built. Initially, United Nations air forces using piston-engined fighter-bombers and straight wing jet fighters easily drove the North Koreans out of the sky and so disrupted logistics and hence the attack on Pusan. All changed when the Soviet Air Force intervened with swept-wing Mikoyan-Gurevich MiG-15s flown by Russian pilots on November 1. The planes had Korean markings and

21539-511: The features that the United States Air Force (USAF) would have liked the RF-84F to have been outfitted with had it been technically possible; one month later, the Air Staff endorsed its development over that of further developing the RF-84F. The USAF promptly issued Republic with an initial contract covering preproduction engineering, tooling, as well as the production of 199 aircraft, the first of which

21720-558: The fighter-bomber role, especially where longer ranges were needed for naval strikes. Examples include the Lockheed P-38 Lightning , the Bristol Beaufighter (developed from a torpedo bomber ), and de Havilland Mosquito (developed from an unarmed fast bomber). The Beaufighter MkV had a Boulton-Paul turret with four 0.303 in (7.7 mm) machine guns mounted aft of the cockpit but only two were built. Bristol's Blenheim

21901-566: The fighter-bomber role. Notable examples include the Focke-Wulf Fw 190 , Hawker Typhoon and Republic P-47 Thunderbolt . Various bombing tactics and techniques could also be used: some designs were intended for high-level bombing , others for the low-level semi-horizontal bombing, or even for low-level steep dive bombing as exemplified by the Blackburn Skua and North American A-36 Apache . Larger twin-engined aircraft were also used in

22082-483: The fire and movement of friendly forces is not required" (Annex 3-03, Counterland Operations). Close Air Support is defined as "air action by fixed- and rotary-winged aircraft against hostile targets that are in close proximity to friendly forces and which require detailed integration of each air mission with the fire and movement of those forces" (JP 1-02). This can be as a pre-planned event or on demand from an alert posture (ground or airborne). It can be conducted across

22263-457: The first Allied jet fighter of WWII but no match for a MiG-15. It was pressed into combat but after four were lost when the squadron was bounced by 40 Mig-15s, reverted to ground attack, carrying 16 60 lb (27 kg) rockets. Although Meteors shot down 6 MiG-15s, 30 were lost, but mainly to ground fire. Both Corsairs and Sea Furies also shot down MiG-15s, but were vulnerable to the faster jet. Fighter-bombers became increasingly important in

22444-457: The first Thunderstick II aircraft flew in 1969, they were not used in Vietnam. A total of 30 F-105Ds received this modification. They were initially assigned to the 563TFS/23TFW at McConnell AFB. In the summer 1972, they were all transferred to the newly reactivated 457TFS (AFRES) at Carswell AFB. This remained the only unit to fly the Thunderstick II until its retirement in 1981–82. In 1965,

22625-582: The first of many successful attacks on the Paul Doumer bridge over the Red River. Flying low-altitude missions and conducting dive bombings forced the F-105s into range of North Vietnamese anti-aircraft guns, sometimes coming under heavy fire. USAF F-105s were escorted by F-4s to protect them against enemy fighters. However, the Thunderchief was officially credited with 27.5 air-to-air victories against VPAF aircraft at

22806-574: The first prototype attained the speed of Mach 1.2 on its maiden flight. (The J75 was expected to generate 24,500 lbf (109 kN) with afterburner.) Both aircraft featured conventional wing root air intakes and slab-sided fuselages typical of the early jets; Republic viewed the prototypes as not being representative of the true capability of the aircraft due to numerous changes that were enacted prior to production. Specifically, insufficient power and aerodynamic problems with transonic drag , as well as Convair 's experience with their F-102 , had led to

22987-460: The fuselage. Thirty aircraft were fitted with pylons to carry the AGM-78 Standard anti-radiation missile . On a typical mission, the F-105G carried two Shrikes on outboard pylons, a single Standard on an inboard pylon balanced by a 450 US gal (1,700 L) fuel tank on the other side, and a 650 US gal (2,500 L) centerline fuel tank. The F-105B entered USAF service with

23168-603: The globe to conduct current and future operations. Planning and directing is "the determination of intelligence requirements, development of appropriate intelligence architecture, preparation of a collection plan, and issuance of orders and requests to information collection agencies" (JP 2-01, Joint and National Intelligence Support to Military Operations). These activities enable the synchronization and integration of collection, processing, exploitation, analysis, and dissemination activities/resources to meet information requirements of national and military decision-makers. Collection

23349-442: The intention of taking the initiative" (JP 1-02). It includes detection and warning; chemical, biological, radiological, and nuclear defense; camouflage, concealment, and deception; hardening; reconstitution; dispersion; redundancy; and mobility, counter-measures, and stealth. Airspace control is "a process used to increase operational effectiveness by promoting the safe, efficient, and flexible use of airspace" (JP 1-02). It promotes

23530-619: The invasion. USAF North American F-82 Twin Mustangs had the range to reach the front line from Japanese bases. The last piston-engined aircraft, produced in the U.S., it looked like two Mustangs, with two pilots in separate fuselages, bolted together. Initially intended to escort bombers over Japan from remote Pacific island bases, hence its long-range, it missed WWII and first saw action in Korea. Plain North American P-51 Mustangs of

23711-762: The jets of its main British and US opponents, which used the older Rolls-Royce Derwent design. Only the Navy Grumman F9F Panther used a version of the Nene and could match the MiG-15, accounting for seven during November. Daylight heavy bomber raids over North Korea ceased and the Lockheed F-80 Shooting Star and its all-weather variant the Lockheed F-94 Starfire were focused on bombing missions whilst

23892-710: The largest raid since the Blitz . Flying at sea level, under the radar, these raids were hard to intercept. The Jabos reached the Eastern Front in time to bomb Russian positions in Stalingrad . By July 1943 Fw 190s were replacing the vulnerable Stukas over the Battle of Kursk : although winning the air war, they were unable to prevent subsequent Red Army advances. On New Year's Day 1945 in Operation Bodenplatte , over 1,000 aircraft (including more than 600 Fw 190s) launched

24073-424: The late 1950s, for a time based on the F-105D, before work on the model was cancelled for the final time on 23 December 1960. On 18 March 1959, the planned F-105E twin-seater was also cancelled due to its high cost; it was replaced on a one-to-one basis by additional F-105Ds. On 9 June 1959, the first F-105D took its maiden flight. Flight testing of the F-105D was somewhat less troubled than the less advanced F-105B, to

24254-523: The massive, seven-ton USAAF Republic P-47 Thunderbolt —a single Pratt & Whitney R-2800 Double Wasp radial engine of 2,000 hp (1,500 kW) in a much smaller, simpler and less expensive single-seat aircraft, and was the first aircraft design to ever fly with the Double Wasp engine in May 1940. With less airframe and crew to lift, the Corsair's ordnance load was either four High Velocity Aircraft Rockets or 2,000 lb (910 kg) of bombs;

24435-727: The mid-2030s. On 22 October 2023, the USAF conducted its first-ever trilateral exercise with the South Korean and Japanese air forces near the Korean Peninsula. On 29 November 2023, a USAF Bell Boeing V-22 Osprey crashed in the Japan island of Yakushima killing 1 airman. In 2024, citing the Supreme Court 's ruling in Loper Bright Enterprises v. Raimondo , the Air Force refused to comply with an EPA order that they develop

24616-454: The more powerful Pratt & Whitney J75 . Anticipating a protracted development of the engine, it was expected that the first aircraft would use the smaller Pratt & Whitney J57 . Near the end of 1953, the entire program was suspended by the USAF due to a number of delays and uncertainties regarding the aircraft. However, on 28 June 1954, the USAF officially ordered 15 F-105s (two YF-105As, four YF-105Bs, six F-105Bs, and three RF-105Bs) under

24797-546: The most successful Allied aircraft of the First World War with 1,294 enemy aircraft downed, was losing its edge by 1918, especially over 12,000 ft (3,700 m). During the final German offensive in March 1918, it dropped 25 lb (11 kg) Cooper bombs on advancing columns: whilst puny by later standards, the four fragmentation bombs carried by a Camel could cause serious injuries to exposed troops. Pilot casualties were also high. The Royal Aircraft Factory S.E.5 .

24978-477: The nose free for a radome housing the multi-mode radar. Its fuselage provided room for 1,184 US gallons (4,480  L ) of fuel and an internal bomb bay. The bomb bay measured 15 feet 10 inches (4.83 m) by 32 in (0.81 m) by 32 in (0.81 m); it was originally designed to carry a single nuclear weapon but typically held an additional 350 US gal (1,300 L) fuel tank. It featured four under-wing and one centerline pylon;

25159-423: The outer wing pylons. The F-105 was designed primarily for low-level interdiction and its low-altitude speed was its greatest asset when dealing with enemy fighters such as the MiG-17 / J-5s and MiG-21 . The F-105 managed 27.5 air-to-air victories. Based on combat experience, the F-105D was updated with a better ejection seat , additional armor, improved gun sights, and Electronic Counter Measures (ECM) pods on

25340-506: The pilot towards the targets. However, the F-100F was an interim solution, since its limited payload often required multiple aircraft to conduct a successful strike; it also lacked the speed and endurance to effectively protect the F-105. The resulting EF-105F Wild Weasel III (the EF designation was popularly used but unofficial) supplemented its sensors and electronic jamming equipment with AGM-45 Shrike anti-radiation missiles and conventional bombs, giving it an offensive capability lacking in

25521-450: The pilots had been taught a few Korean words, in a thin sham that the USSR was not fighting. The MiG-15 used captured German swept wing technology and tools and British jet engines, 25 of which had been a gift from Stafford Cripps the president of the Board of Trade and were quickly copied. Josef Stalin remarked “What fool will sell us his secrets?” The MiG's Rolls-Royce Nene had 5,000 lbf (2,300 kgf) thrust, twice as much as

25702-415: The planes that the USAF planned to buy in the future were to be unmanned. According to Air Force Chief Scientist, Greg Zacharias , the USAF anticipates having hypersonic weapons by the 2020s, hypersonic unmanned aerial vehicles (also known as remotely-piloted vehicles, or RPAs) by the 2030s and recoverable hypersonic RPAs aircraft by the 2040s. The USAF intends to deploy a Sixth-generation jet fighter by

25883-412: The point where the D-model was ready for operational service ahead of its predecessor. Category II flight testing in late 1959 identified various key deficiencies on the F-105B, particularly with the MA-8 fire control system and autopilot of this variant. While eventually rectified successfully, it took time to develop and deploy appropriate modifications, putting the production programme further behind. By

26064-486: The potential consequences of an accident or unauthorized act, nuclear weapons and nuclear weapon systems require special consideration and protection against risks and threats inherent in their peacetime and wartime environments. In conjunction with other entities within the Departments of Defense or Energy, the Air Force achieves a high standard of protection through a stringent nuclear surety program. This program applies to materiel, personnel, and procedures that contribute to

26245-483: The production of intelligence" (JP 2-01). It provides the ability to transform, extract, and make available collected information suitable for further analysis or action across the ROMO. Analysis and production is "the conversion of processed information into intelligence through the integration, evaluation, analysis, and interpretation of all source data and the preparation of intelligence products in support of known or anticipated user requirements" (JP 2-01). It provides

26426-481: The production run and by 1964, early F-105Ds were upgraded with these fixes under Project Look Alike , although engine failures and fuel system problems persisted until 1967. Meanwhile, the USAF was gradually changing the anticipated F-105 mission from nuclear interdiction to conventional bombing. The Look Alike upgrades increased the aircraft's capacity from four to 16 conventional 750 lb (340 kg) bombs on underwing and fuselage centerline hardpoints and added

26607-409: The purpose of the USAF as: The five core missions of the Air Force have not changed dramatically since the Air Force became independent in 1947, but they have evolved and are now articulated as air superiority, global integrated ISR (intelligence, surveillance and reconnaissance), rapid global mobility, global strike, and command and control. The purpose of all of these core missions is to provide what

26788-400: The reliability and weapons capacity of the existing F-105Ds. In response to the surface-to-air missile threat experienced in the skies above Vietnam, dozens of F-105Fs were converted into anti-radar "Wild Weasel" aircraft, culminating with the F-105G. The F-105 was a mid-wing monoplane with a 45° swept wing and tail surfaces. The single engine was fed by two intakes in the wing roots, leaving

26969-491: The safe, efficient, and flexible use of airspace, mitigates the risk of fratricide, enhances both offensive and defensive operations, and permits greater agility of air operations as a whole. It both deconflicts and facilitates the integration of joint air operations. Global integrated intelligence, surveillance, and reconnaissance (ISR) is the synchronization and integration of the planning and operation of sensors, assets, and processing, exploitation, dissemination systems across

27150-546: The safety, security, and control of nuclear weapons, thus assuring no nuclear accidents, incidents, loss, or unauthorized or accidental use (a Broken Arrow incident ). The Air Force continues to pursue safe, secure and effective nuclear weapons consistent with operational requirements. Adversaries, allies, and the American people must be highly confident of the Air Force's ability to secure nuclear weapons from accidents, theft, loss, and accidental or unauthorized use. This day-to-day commitment to precise and reliable nuclear operations

27331-419: The same timing. The resulting North American P-51 Mustang powered by a Packard-built Rolls-Royce Merlin engine became the outstanding long-range fighter of the war. When Lend-lease funding for the RAF Mustangs was exhausted, Kindleberger tried to interest the USAAC but no funds were available for a fighter; instead, the Mustang was fitted with dive brakes and emerged as the North American A-36 Apache ,

27512-438: The second by cannon fire and the third by jettisoning the centerline rack full of bombs directly into the path of a surprised MiG. On 31 May 1968, a dedication ceremony took place at the United States Air Force Academy to honor graduates who had served in Vietnam. An F-105, which had been assembled using parts from ten different F-105s that had seen service in Vietnam, was placed on permanent static display. The ceremony included

27693-402: The single-file pass and exceeded the speed of sound at less than 100 feet. The ensuing sonic boom broke hundreds of windows and fifteen people sustained cuts. Two Wild Weasel pilots received the Medal of Honor : As production of F-105s had ended, the type was replaced in the Vietnam War by other aircraft, primarily the F-4 Phantom II. In October 1970, the 355th Tactical Fighter Wing , which

27874-409: The site. These anti-aircraft guns were lethal at close range and the Vietnamese shot down six aircraft, while more than half of the remaining U.S. aircraft suffered damage from ground fire. Both surface-to-air missile sites were devoid of missiles and equipment, and the Vietnamese had substituted white-painted bundles of bamboo for the real SA-2s. Operation Spring High destroyed two worthless targets at

28055-402: The sound barrier in his X-1 rocket-powered aircraft, beginning a new era of aeronautics in America. The predecessor organizations in the Army of today's Air Force are: During the early 2000s, two USAF aircraft procurement projects took longer than expected, the KC-X and F-35 programs. As a result, the USAF was setting new records for average aircraft age. Since 2005, the USAF has placed

28236-496: The start of 1960, none of the 56 F-105Bs that had been delivered were considered to be operationally ready. At one point, there were plans in progress to procure in excess of 1,500 F-105Ds; however, production schedules continued to be missed, in part due to strikes by Republic's workforce, that impacted the USAF's plans for the type. Production of the F-105 was heavily impacted by the decision taken by Secretary of Defense Robert McNamara to equip no more than seven combat wings with

28417-416: The surface. On April 9, 1945, three were sunk en route to Norway, and in the following month, Mosquitos sank two more. The Hawker Typhoon was being designed as a replacement for the Hurricane in March 1937 before production had even started. The reason was to take advantage of the new 2,000 hp (1,500 kW) engines then being planned, either the Napier Sabre or Rolls-Royce Vulture which required

28598-415: The two inner wing and centerline pylons were capable of accepting fuel from 450 and 650 US gal (1,700 and 2,500 L) drop tanks . Two outer dry stations were wired for missiles or bombs. One M61 Vulcan (initially designated T-171E3 ) 20 mm 6-barrel Gatling-style cannon was installed in the left side of the nose. A short-range AIM-9 Sidewinder air-to-air missile could be carried on each of

28779-433: The type. During November 1961, production of the type was cut in favor of the USAF adopting the Navy's F-4 Phantom II, and in the longer term, the General Dynamics F-111 Aardvark of the TFX program. While considerations towards reopening production of the F-105 were discussed in 1967, this interest did not ultimately see any such revival. The final 143 Thunderchiefs built were of the two-seat F-105F trainer variant. Based on

28960-418: The vicinity of Hanoi would routinely travel around mountainous terrain nicknamed Thud Ridge to evade the air defenses surrounding the city. Colonel Jack Broughton , an F-105 pilot in Vietnam, noted the demands of flying close to Hanoi gave "simply no room for error". On 11 August 1967, F-105Ds from 335th Tactical Fighter Squadron with support from F-105 Wild Weasels from 338th Tactical Fighter Squadron made

29141-476: The war involved an attack on 14 August 1964 against an anti-aircraft artillery site on Plaine des Jarres . This mission was carried out by aircraft of the 36th TFS, 6441st Tactical Fighter Wing deployed from Yokota Air Base , Japan to Korat Royal Thai Air Force Base , Thailand. The first Thunderchief lost in the war also occurred during this mission, although the pilot managed to return the aircraft to Korat. The first strike mission took place on 13 January 1965 with

29322-580: The war the USAF began transferring the remaining aircraft to Air Force Reserve (AFRES) and Air National Guard (ANG) units. By the late 1970s, these aging Thunderchiefs were becoming difficult to maintain. The last F-105Gs with the 128th Tactical Fighter Squadron of the Georgia ANG were retired on 25 May 1983. The last flight of the F-105 Thunderchief was by the AFRES 466th Tactical Fighter Squadron with F-105Ds on 25 February 1984. Data from The Great Book of Fighters , Quest for Performance , U.S. Standard Aircraft Characteristics: F-105D-31 , Jane's All

29503-417: The war, with only the infantry suffering more casualties. In practice, the U.S. Army Air Forces ( USAAF ) was virtually independent of the Army during World War II, and in virtually every way functioned as an independent service branch, but airmen still pressed for formal independence. The National Security Act of 1947 was signed on 26 July 1947, which established the Department of the Air Force , but it

29684-452: The wings. Former North American F-86 Sabre pilot Jerry Noel Hoblit recalled being in awe of the F-105's size after seeing it for the first time; he could not manage to reach the air intake lip even with a running jump. The F-105 had a spacious cockpit with good visibility and layout (particularly after the introduction of "tape" instruments); the advanced electronics were easy to learn and operate. Takeoffs and landings were often performed in

29865-518: The worst one-day loss in its history; it never recovered. The Bristol Blenheim and Douglas A-20 Havoc (which the RAF called Boston) were used as night fighters during the Blitz , as they could carry the heavy early airborne radars. The Hawker Henley , a two-seat version of the Battle of Britain -winning Hawker Hurricane , was designed as a dive bomber. It might have proved to be a capable fighter-bomber but overheating of its Rolls-Royce Merlin engine in this installation led to its relegation to

30046-522: Was based at Takhli RTAFB, Thailand, and was the last F-105D unit in Southeast Asia, began to return to the U.S. The F-105G Wild Weasel versions soldiered on until the end of the war. They were gradually replaced by F-4G Wild Weasel IVs. The Thunderchief was rapidly withdrawn from USAF service after the end of the Vietnam War. Of the 833 F-105s built, a combined 395 F-105s were lost in Southeast Asia, including 334 (296 F-105Ds and 38 two-seaters) lost to enemy action and 61 lost in operational accidents. Following

30227-458: Was damaged and February 9, 1945, became known as Black Friday . Typhoons were involved in one of the worst tragedies at the end of the war when four squadrons attacked the luxury liners SS Deutschland and the SS Cap Arcona and two smaller ships SS Athen and SS Thielbek moored off Neustadt in Lübeck Bay The Cap Arcona had 4,500 concentration camp inmates and the Thielbek another 2,800 as well as SS Guards. The Deutschland had

30408-428: Was effective in reducing F-105D losses, the Weasel aircraft suffered heavy casualties with five of the first 11 lost in July and August 1966. Attacks into high-risk environments saw the Weasels operating in "Iron Hand" hunter-killer flights of mixed single-seat and two-seat Thunderchiefs, suppressing sites during attacks by the strike force and attacking others en route. In the fall of 1967, EF-105Fs began to be upgraded to

30589-425: Was even pushed into service as a fighter during the Battle of Britain but it was not fast enough. Equipped with an early Airborne Interception (AI) radar set, however, it proved to be an effective night fighter. The first single-seat fighters to drop bombs were on the Western Front , when fighter patrols were issued with bombs and ordered to drop them at random if they met no German fighters. The Sopwith Camel ,

30770-491: Was fitted with racks to carry two 500 lb (230 kg) and then two 1,000 lb (450 kg) bombs. By September 1943 it was fitted with eight RP-3 rockets each with a 60 lb (27 kg) warhead, equivalent to the power of a naval destroyer's broadside. Claims of German tanks destroyed by rocket-armed Typhoons in Normandy after D-Day were exaggerated. In Operation Goodwood , the attempt by British and Canadian forces to surround Caen of 75 tanks recorded as lost by

30951-441: Was intended to have two machine guns jutting through the cockpit floor so as to spray trenches with bullets as it passed low overhead. But this did not work and it was fitted with four Cooper bombs, instead. It was ordered in very large numbers, but most were canceled after the Armistice . In February and April 1918 the Royal Flying Corps conducted bombing tests at Orfordness , Suffolk dropping dummy bombs at various dive angles at

31132-493: Was later claimed by the North as downed by a MiG-17. One F-105 piloted narrowly escaped. USAF Chief of Staff General John P. McConnell was "hopping mad" to hear that two F-105s had been shot down by Korean War-era subsonic North Vietnamese MiGs. The Thanh Hoa Bridge proved resistant to aerial bombing; multiple missions were flown to damage the bridge both by F-105s and U.S. Navy aircraft. On 24 July 1965, four U.S. Air Force McDonnell F-4C Phantoms took part in an airstrike against

31313-453: Was modified to carry four 20mm cannon and two 500 lb (230 kg) bombs; once bombs were jettisoned the aircraft could put up a reasonable fight. Inevitably the type became known in the RAF as the “Hurribomber”, reaching squadrons in June 1941. It was soon found that it was hardly possible to hit fast-moving Panzers in the Western Desert , with bombs and cannon fire-making little impact on their armour. Daylight bombing raids were made on

31494-415: Was moored close to the vertical cliffside of the fjords so Beaufighters had to attack singly with rockets without the normal tactic of having simultaneous attacks by other Beaufighters firing cannon at the numerous flak gunners. Twelve Focke-Wulf Fw 190s surprised the Mustangs and Norway's biggest ever air battle was soon raging. Nine Beaufighters and one Mustang were lost as were five Fw 190s. The destroyer

31675-459: Was not fully operational on the F-105D until early 1961. The first overseas F-105 units formed in West Germany in 1961, with the 36th Tactical Fighter Wing at Bitburg Air Base in May and the 49th Tactical Fighter Wing at Spangdahlem Air Base in October. Both wings had a primary tactical nuclear strike role for NATO . The F-105D was also deployed to the Pacific, with the 18th Tactical Fighter Wing at Kadena in Okinawa converting in 1962 and

31856-414: Was not until 18 September 1947, when the first secretary of the Air Force, W. Stuart Symington , was sworn into office that the Air Force was officially formed as an independent service branch. The act created the National Military Establishment (renamed Department of Defense in 1949), which was composed of three subordinate Military Departments, namely the Department of the Army , the Department of

32037-418: Was rapid. The initial reaction of the fighter pilot community to their new aircraft was lukewarm. Between its massive dimensions and troubled early service life, the F-105 had garnered a number of uncomplimentary nicknames. In addition to the aforementioned "Thud", nicknames included the "Squat Bomber", "Lead Sled", and the "Hyper Hog" and/or "Ultra Hog". The latter two names arose from the F-105's predecessors,

32218-429: Was that he had repeatedly clashed with Wynne and Moseley over other important non-nuclear related issues to the service. This followed an investigation into two incidents involving mishandling of nuclear weapons : specifically a nuclear weapons incident aboard a B-52 flight between Minot AFB and Barksdale AFB , and an accidental shipment of nuclear weapons components to Taiwan. To put more emphasis on nuclear assets,

32399-449: Was the first officer appointed to that position who did not have a background as a fighter or bomber pilot. The Washington Post reported in 2010 that General Schwartz began to dismantle the rigid class system of the USAF, particularly in the officer corps. In 2014, following morale and testing/cheating scandals in the Air Force's missile launch officer community, Secretary of the Air Force Deborah Lee James admitted that there remained

32580-414: Was to be operationally ready by 1955. However, by March 1953, the USAF had reduced the order to 37 fighter-bombers and nine tactical reconnaissance aircraft, citing the approaching end of the Korean War . In October 1953, the F-105 mock-up was inspected; no major changes were recommended. By this point, the aircraft had grown so large that the Allison J71 turbojet intended for it was abandoned in favor of

32761-412: Was used in the same role. The Royal Flying Corps received the first purpose-built fighter-bomber just as the war was ending. It was not called a fighter bomber at the time, but a Trench Fighter as that was what it was designed to attack. The Sopwith Salamander was based on the Sopwith Snipe fighter but had armour plating in the nose to protect the pilot and fuel system from ground fire. Originally it
