151-625: The Lockheed Martin EC-130 series comprises several slightly different versions of the Lockheed C-130 Hercules that have been and continue to be operated by the U.S. Air Force and, until the 1990s, the U.S. Navy . The EC-130E Airborne Battlefield Command and Control Center (ABCCC) was based on a basic C-130E platform and provided tactical airborne command post capabilities to air commanders and ground commanders in low air threat environments. The EC-130E ABCCC aircraft were retired in 2002 and
302-549: A Lockheed P2V Neptune . After the two prototypes were completed, production began in Marietta, Georgia , where over 2,300 C-130s have been built through 2009. The initial production model, the C-130A , was powered by Allison T56 -A-9 turboprops with three-blade propellers and originally equipped with the blunt nose of the prototypes. Deliveries began in December 1956, continuing until
453-527: A 3,200 nmi (5,900 km; 3,700 mi) range. A total of 154 Boeing 720s and 720Bs were built until 1967. Some 720s were later converted to the 720B specification. The 720 was succeeded by the Boeing 727 trijet. The 707-120 was the first production 707 variant, with a longer, wider fuselage, and greater wingspan than the Dash 80. The cabin had a full set of rectangular windows and could seat up to 189 passengers. It
604-531: A 5 percent-scale model of a widebody design with a 303,000 lb (137,000 kg) take-off gross weight and an " A400M -size" 158 in (4.0 m) wide cargo box. It would be powered by four IAE V2533 turbofans. In August 2011, the AFRL released pictures of the Lockheed Speed Agile concept demonstrator. A 23% scale model went through wind tunnel tests to demonstrate its hybrid powered lift, which combined
755-406: A Dutch roll incident he experienced as a passenger on an early commercial 707 flight. As the aircraft's movements did not cease and most of the passengers became ill, he suspected a misrigging of the directional autopilot (yaw damper). He went to the cockpit and found the crew unable to understand and resolve the situation. He introduced himself and relieved the ashen-faced captain who immediately left
906-451: A Hercules achieved and still holds the record for the largest and heaviest aircraft to land on an aircraft carrier . During October and November that year, a USMC KC-130F (BuNo 149798 ), loaned to the U.S. Naval Air Test Center, made 29 touch-and-go landings , 21 unarrested full-stop landings and 21 unassisted take-offs on Forrestal at a number of different weights. The pilot, Lieutenant (later Rear Admiral) James H. Flatley III , USN,
1057-500: A change from direct mechanical linkages assisted by hydraulic boost, to fully powered controls, in which the mechanical linkages from the flight station controls operated only the hydraulic control valves of the appropriate boost unit. The HTTB first flew on 19 June 1984, with civil registration of N130X. After demonstrating many new technologies, some of which were applied to the C-130J, the HTTB
1208-414: A convertible passenger–freight configuration, which became the most widely produced variant of the 707. The 707-320C added a strengthened floor and a new cargo door to the -320B model. The wing was fitted with three-section leading-edge flaps which allowed the removal of the underfin. A total of 335 of this variant were built, including some with JT3D-7 engines (19,000 lbf (85 kN) takeoff thrust) and
1359-454: A demonstration flight over Lake Washington outside Seattle , on August 7, 1955, test pilot Tex Johnston performed a barrel roll in the 367-80 prototype. Although he justified his unauthorized action to Bill Allen , then president of Boeing, as selling the airplane with a 1 'g' maneuver he was told not to do it again. The 132 in (3,400 mm) wide fuselage of the Dash 80 was large enough for four-abreast (two-plus-two) seating like
1510-399: A duct system to the control surfaces and flaps during landing. This greatly reduced landing speed to just 63 knots and cut landing distance in half. The system never entered service because it did not improve takeoff performance by the same margin, making the landing performance pointless if the aircraft could not also take off from where it had landed. An electronic reconnaissance variant of
1661-787: A family of other special missions aircraft. 37 of the earliest models currently operating with the Air Force Special Operations Command (AFSOC) are scheduled to be replaced by new-production MC-130J versions. The EC-130 Commando Solo is another special missions variant within AFSOC, albeit operated solely by an AFSOC-gained wing in the Pennsylvania Air National Guard , and is a psychological operations/information operations (PSYOP/IO) platform equipped as an aerial radio station and television stations able to transmit messaging over commercial frequencies. Other versions of

Three C-130Ks (Hercules C Mk.1P) were upgraded and sold to the Austrian Air Force in 2002. The MC-130E Combat Talon was developed for the USAF during the Vietnam War to support special operations missions in Southeast Asia, and led to both the MC-130H Combat Talon II as well as
1963-544: A four-turboprop Douglas design. The Lockheed design team was led by Willis Hawkins , starting with a 130-page proposal for the Lockheed L-206 . Hall Hibbard , Lockheed vice president and chief engineer, saw the proposal and directed it to Kelly Johnson , who did not care for the low-speed, unarmed aircraft, and remarked, "If you sign that letter, you will destroy the Lockheed Company." Both Hibbard and Johnson signed
2114-484: A fuselage 55 feet (17 m) longer than the 707-320B, to 208.6 feet (63.6 m) in length. This second model would have carried 225 passengers in mixed-class configuration and 279 passengers in all-economy configuration. Like the 707-620, the 707-820 was also set to compete with the stretched DC-8-60 Super Series models. The design was being pitched to American, TWA, BOAC, and Pan Am at the time of its proposal in early 1965. The 707-820 would have cost US$ 10,000,000. Like
2265-492: A half hours at low altitude in the dark, they arrived over the target and the sensor pallets were dropped by parachute near Anxi in Gansu province. After another six and a half hours of low-altitude flight, they arrived back at Takhli. The sensors worked and uploaded data to a U.S. intelligence satellite for six months before their batteries failed. The Chinese conducted two nuclear tests, on 22 September 1969 and 29 September 1969, during
2416-682: A higher gross weight. Australia took delivery of 12 C130E Hercules during 1966–67 to supplement the 12 C-130A models already in service with the RAAF. Sweden and Spain fly the TP-84T version of the C-130E fitted for aerial refueling capability. The KC-130 tankers , originally C-130F procured for the US Marine Corps (USMC) in 1958 (under the designation GV-1 ) are equipped with a removable 3,600 US gallons (14,000 L) stainless steel fuel tank carried inside
2567-565: A joint rescue mission that used the C-130s to drop, air-land, and air-lift a force of Belgian paratroopers to rescue the hostages. Two missions were flown, one over Stanleyville and another over Paulis during Thanksgiving week. The headline-making mission resulted in the first award of the prestigious MacKay Trophy to C-130 crews. In the Indo-Pakistani War of 1965 , the No. 6 Transport Squadron of
2718-648: A joint venture with Seven Q Seven (SQS) and Omega Air, selected the JT8D-219 low-bypass turbofan as a replacement powerplant for Boeing 707-based aircraft, calling their modified configuration a 707RE. Northrop Grumman selected the -219 to re-engine the US Air Force's fleet of 19 E-8 Joint STARS aircraft, which would allow the J-STARS more time on station due to the engine's greater fuel efficiency. NATO also planned to re-engine their fleet of E-3 Sentry AWACS aircraft. The -219
2869-463: A kink in the trailing edge to add area inboard. Takeoff weight was increased to 302,000 lb (137,000 kg) initially and to 312,000 lb (142,000 kg) with the higher-rated JT4As and center section tanks. Its first flight was on January 11, 1958; 69 turbojet 707-320s were delivered through January 1963, the first passengers being carried (by Pan Am) in August 1959. The 707-420 was identical to
3020-439: A lighter short-range variant, was also introduced in 1960. Powered by Pratt & Whitney JT3D turbofans, the 707-120B debuted in 1961 and the 707-320B in 1962. The 707-120B typically flew 137 passengers in two classes over 3,600 nautical miles [nmi] (6,700 km; 4,100 mi), and could accommodate 174 in one class. With 141 passengers in two classes, the 707-320/420 could fly 3,750 nmi (6,940 km; 4,320 mi) and
3171-436: A longer fuselage and wing meant a painstaking redesign of the wing and landing-gear structures. Rather than spend money on upgrading the 707, engineer Joe Sutter stated the company "decided spending money on the 707 wasn't worth it". The project was cancelled in 1966 in favor of the newer Boeing 747. The 707-820 was a proposed intercontinental stretched variant of the 707-320B. This 412,000-pound MTOW (187,000 kg) variant

#17330849184303322-476: A low drag airframe with simple mechanical assembly to reduce weight and improve aerodynamics. The model had four engines, including two Williams FJ44 turbofans. On 26 March 2013, Boeing was granted a patent for its swept-wing powered lift aircraft. In January 2014, Air Mobility Command , Air Force Materiel Command and the Air Force Research Lab were in the early stages of defining requirements for
3473-588: A multitude of worldwide standards throughout the TV VHF/UHF ranges. Secondary missions include command and control communications countermeasures (C3CM) and limited intelligence gathering. The three variants are EC-130 ABCCC, EC-130E Commando Solo, and the EC-130J Commando Solo. The version currently in service is the EC-130J, as the last EC-130E was retired from service in 2006. The USAF plans to begin replacing
3624-450: A range of 1,100 nmi (1,270 mi; 2,040 km) and it could operate from short and unprepared strips. Fairchild, North American, Martin, and Northrop declined to participate. The remaining five companies tendered a total of ten designs: Lockheed two, Boeing one, Chase three, Douglas three, and Airlifts Inc. one. The contest was a close affair between the lighter of the two Lockheed (preliminary project designation L-206) proposals and
3775-534: A redesigned outer wing , updated avionics, and other minor improvements. Later H models had a new, fatigue-life-improved, center wing that was retrofitted to many earlier H-models. For structural reasons, some models are required to land with reduced amounts of fuel when carrying heavy cargo, reducing usable range. The H model remains in widespread use with the United States Air Force (USAF) and many foreign air forces. Initial deliveries began in 1964 (to
3926-650: A stronger structure to support a maximum takeoff weight increased by 19,000 lb (8,600 kg), along with modifications to the wing. The 707-320B series enabled nonstop westbound flights from Europe to the West Coast of the United States and from the US to Japan. The final 707 variant was the 707-320C, (C for "Convertible"), which had a large fuselage door for cargo. It had a revised wing with three-sectioned leading-edge flaps, improving takeoff and landing performance and allowing
4077-588: A takeoff weight of 335,000 lb (152,000 kg). Most -320Cs were delivered as passenger aircraft with airlines hoping the cargo door would increase second-hand values. The addition of two additional emergency exits, one on either side aft of the wing raised the maximum passenger limit to 219. Only a few aircraft were delivered as pure freighters. One of the final orders was by the Iranian Government for 14 707-3J9C aircraft capable of VIP transportation, communication, and in-flight refueling tasks. The 707-700
4228-580: A threat to the 757 and 767 programs. The information gathered from testing led to the eventual retrofitting of CFM56 engines to the USAF C-135/KC-135R models, and some military versions of the 707 also used the CFM56. The Douglas DC-8 "Super 70" series with CFM56 engines was developed and extended the DC-8's life in a stricter noise regulatory environment. As a result, significantly more DC-8s remained in service into
4379-456: A viable option because the installation of larger, more powerful engines would need a larger undercarriage, which was not feasible given the design's limited ground clearance at takeoff. Boeing's answer to the problem was the first wide-body airliner—the Boeing 747 . The 707's first-generation engine technology was also rapidly becoming obsolete in the areas of noise and fuel economy, especially after
4530-517: A year. The only rival in intercontinental jet aircraft production at the time was the British de Havilland Comet. However, the Comet series had been the subject of fatal accidents (due to design flaws) early in its introduction and withdrawn from service; virtually redesigned from scratch, it was still smaller and slower than the 707 when reintroduced as version -4. In addition, airlines and their passengers at
4681-463: Is a reconnaissance version developed during the Cold War. Sometimes called "ferret" aircraft, these planes were initially retrofitted standard C-130s. The Lockheed L-100 (L-382) is a civilian variant, equivalent to a C-130E model without military equipment. The L-100 also has two stretched versions. In the 1970s, Lockheed proposed a C-130 variant with turbofan engines rather than turboprops, but

4832-588: Is an American four-engine turboprop military transport aircraft designed and built by Lockheed (now Lockheed Martin ). Capable of using unprepared runways for takeoffs and landings, the C-130 was originally designed as a troop, medevac , and cargo transport aircraft . The versatile airframe has found uses in other roles, including as a gunship ( AC-130 ), for airborne assault , search and rescue , scientific research support, weather reconnaissance, aerial refueling , maritime patrol , and aerial firefighting . It

Additional aircraft were modified for electronics intelligence work and assigned to Rhein-Main Air Base , Germany while modified RC-130As were assigned to the Military Air Transport Service (MATS) photo-mapping division. The C-130A entered service with the U.S. Air Force in December 1956. In 1958, a U.S. reconnaissance C-130A-II of the 7406th Support Squadron
5889-456: The 377 Stratocruiser , quickly faded with only 56 examples sold and no new orders as the 1940s drew to a close. That venture had netted the company a $ 15 million loss. During 1949 and 1950, Boeing embarked on studies for a new jet transport and saw advantages with a design aimed at both military and civilian markets. Aerial refueling was becoming a standard technique for military aircraft, with over 800 KC-97 Stratofreighters on order. The KC-97

These improvised bombers were used to hit Indian targets such as bridges, heavy artillery positions, tank formations, and troop concentrations, though weren't that successful . In October 1968, a C-130Bs from the 463rd Tactical Airlift Wing dropped a pair of M-121 10,000 pounds (4,500 kg) bombs that had been developed for
6644-583: The RNZAF ), remaining in production until 1996. An improved C-130H was introduced in 1974, with Australia purchasing 12 of the type in 1978 to replace the original 12 C-130A models, which had first entered Royal Australian Air Force (RAAF) service in 1958. The U.S. Coast Guard employs the HC-130H for long-range search and rescue, drug interdiction, illegal migrant patrols, homeland security, and logistics. C-130H models produced from 1992 to 1996 were designated as C-130H3 by

Announced in July 1957 as a derivative for shorter flights from shorter runways, the 707-020 first flew on November 23, 1959. Its type certificate was issued on June 30, 1960, and it entered service with United Airlines on July 5, 1960. As a derivative, the 720 had low development costs, allowing profitability despite few sales. Compared to

The 707-620 was to carry around 200 passengers while retaining several aspects of the 707-320B. It would have been delivered around 1968 and would have also been Boeing's answer to the stretched Douglas DC-8 Series 60 . Had the 707-620 been built, it would have cost around US$ 8,000,000. However, engineers discovered that

The current cost per aircraft is US$ 14 million , although Boeing expects that this price will drop to US$ 7 million for the 69th aircraft. In the 2000s, Lockheed Martin and the U.S. Air Force began outfitting and retrofitting C-130s with the eight-blade UTC Aerospace Systems NP2000 propellers. An engine enhancement program saving fuel and providing lower temperatures in
9513-816: The C-130 in the 1970s through the Advanced Medium STOL Transport project, which resulted in the C-17 Globemaster III that instead replaced the C-141 Starlifter . The Air Force Research Laboratory funded Lockheed Martin and Boeing demonstrators for the Speed Agile concept, which had the goal of making a STOL aircraft that could take off and land at speeds as low as 70 kn (130 km/h; 81 mph) on airfields less than 2,000 ft (610 m) long and cruise at Mach 0.8-plus. Boeing's design used upper-surface blowing from embedded engines on
9664-408: The C-130B was designated C-130B-II. A total of 13 aircraft were converted. The C-130B-II was distinguished by its false external wing fuel tanks, which were disguised signals intelligence (SIGINT) receiver antennas. These pods were slightly larger than the standard wing tanks found on other C-130Bs. Most aircraft featured a swept blade antenna on the upper fuselage, as well as extra wire antennas between
9815-430: The C-X next generation airlifter program to replace both the C-130 and C-17. The aircraft would be produced from the early 2030s to the 2040s. The first production batch of C-130A aircraft were delivered beginning in 1956 to the 463d Troop Carrier Wing at Ardmore AFB , Oklahoma, and the 314th Troop Carrier Wing at Sewart AFB , Tennessee. Six additional squadrons were assigned to the 322d Air Division in Europe and
9966-460: The DC-8, such as United , Delta , and Eastern , were left without jets until September and lost market share on transcontinental flights. Qantas was the first non-US airline to use the 707s, starting in 1959. The 707 quickly became the most popular jetliner of its time. Its success led to rapid developments in airport terminals, runways, airline catering, baggage handling, reservations systems, and other air transport infrastructure. The advent of
10117-435: The EC-130 Commando Solo was instrumental in the success of coordinated psychological operations in Operation Just Cause , again broadcasting continuously throughout the initial phases of the operation to help end the Manuel Noriega regime. In 1990, the EC-130E joined the newly formed Air Force Special Operations Command ( AFSOC ) and has since been designated Commando Solo, with no change in mission. More recently, in 1994,
10268-437: The EC-130E Commando Solo was used to broadcast radio and television messages to the citizens and leaders of Haiti during Operation Uphold Democracy . The EC-130s deployed early in the operation, highlighting the importance of PSYOP in avoiding military and civilian casualties. President Aristide was featured on the broadcasts which contributed significantly to the orderly transition from military rule to democracy. The aircraft
10419-433: The EC-130Q was replaced by the U.S. Navy's current TACAMO platform, the Boeing 707 -based E-6 Mercury . in December 2020 ( Fiscal Year 2021), the US Navy announced that it awarded a contract to Lockheed Martin for the purchase the C-130J-30 Hercules as testbed for the TACAMO mission The aircraft selection represents a return to the C-130 platform by the Navy, which for years used the EC-130Q (an older variant despite
10570-437: The Stratocruiser. Answering customers' demands and under Douglas competition, Boeing soon realized this would not provide a viable payload, so it widened the fuselage to 144 in (3,660 mm) to allow five-abreast seating and use of the KC-135's tooling. Douglas Aircraft had launched its DC-8 with a fuselage width of 147 in (3,730 mm). The airlines liked the extra space and six-abreast seating, so Boeing increased
10721-628: The T56 engine has been approved, and the US Air Force expects to save $ 2 billion (~$ 2.58 billion in 2023) and extend the fleet life. In 2021, the Air Force Research Laboratory demonstrated the Rapid Dragon system which transforms the C-130 into a lethal strike platform capable of launching 12 JASSM-ER with 500 kg warheads from a standoff distance of 925 km (575 mi). Future anticipated improvements support includes support for JDAM-ER , mine laying, drone dispersal as well as improved standoff range when 1,900 km (1,200 mi) JASSM-XR become available in 2024. In October 2010,
10872-481: The U.S. Air Force preferred the takeoff performance of the existing aircraft. In the 1980s, the C-130 was intended to be replaced by the Advanced Medium STOL Transport project. The project was canceled and the C-130 has remained in production. Building on lessons learned, Lockheed Martin modified a commercial variant of the C-130 into a High Technology Test Bed (HTTB). This test aircraft set numerous short takeoff and landing performance records and significantly expanded
11023-636: The U.S. Air Force released a capability request for information (CRFI) for the development of a new airlifter to replace the C-130. The new aircraft was to carry a 190% greater payload and assume the mission of mounted vertical maneuver (MVM). The greater payload and mission would enable it to carry medium-weight armored vehicles and unload them at locations without long runways. Various options were under consideration, including new or upgraded fixed-wing designs, rotorcraft, tiltrotors , or even an airship . The C-130 fleet of around 450 planes would be replaced by only 250 aircraft. The Air Force had attempted to replace
11174-518: The USAF, with the "3" denoting the third variation in design for the H series. Improvements included ring laser gyros for the INUs , GPS receivers, a partial glass cockpit (ADI and HSI instruments), a more capable APN-241 color radar, night vision device compatible instrument lighting, and an integrated radar and missile warning system. The electrical system upgrade included Generator Control Units (GCU) and Bus Switching units (BSU) to provide stable power to
11325-552: The Vietnam War wound down, the 463rd Troop Carrier/Tactical Airlift Wing B-models and A-models of the 374th Tactical Airlift Wing were transferred back to the United States where most were assigned to Air Force Reserve and Air National Guard units. Another prominent role for the B model was with the United States Marine Corps , where Hercules initially designated as GV-1s replaced C-119s. After Air Force C-130Ds proved
11476-423: The aircraft a certificate of airworthiness, citing insufficient yaw control, excessive rudder forces, and the ability to over-rotate on takeoff, stalling the wing on the ground (a fault of the de Havilland Comet 1). Boeing responded by adding 40 in (100 cm) to the vertical stabilizer, applying full instead of partial rudder boost, and fitting an underfin to prevent over-rotation. These modifications except to
11627-430: The aircraft were upgraded and designated Commando Solo II. The EC-130E variants were replaced with new EC-130J Commando Solo III aircraft built by Lockheed Martin beginning in 2003. Highly specialized modifications have been made to the latest version of the EC-130J (Commando Solo III). Included in these mods are enhanced navigation systems, self-protection equipment, and the capability of broadcasting color television on
11778-444: The arrival of the turbofan-powered 707-120B. The 707-320 Intercontinental is a stretched version of the turbojet-powered 707-120, initially powered by JT4A-3 or JT4A-5 turbojets producing 15,800 lbf (70.3 kN) each (most eventually got 17,500 lbf (77.8 kN) JT4A-11s). The interior allowed up to 189 passengers, the same as the -120 and -220 series, but improved two-class capacity due to an 80-in fuselage stretch ahead of
11929-483: The cargo compartment. The two wing-mounted hose and drogue aerial refueling pods each transfer up to 300 US gallons per minute (1,100 L/min) to two aircraft simultaneously, allowing for rapid cycle times of multiple-receiver aircraft formations, (a typical tanker formation of four aircraft in less than 30 minutes). The US Navy 's C-130G has increased structural strength allowing higher gross weight operation. The C-130H model has updated Allison T56-A-15 turboprops,
12080-494: The case of USAF versions) aerial refueling of combat rescue helicopters, HC-130s are usually the on-scene command aircraft for combat SAR missions (USAF only) and non-combat SAR (USAF and USCG). Early USAF versions were also equipped with the Fulton surface-to-air recovery system , designed to pull a person off the ground using a wire strung from a helium balloon. The John Wayne movie The Green Berets features its use. The Fulton system
12231-399: The classic Hercules in general appearance, the J model has new turboprop engines, six-bladed propellers, digital avionics, and other new systems. In 2000, Boeing was awarded a US$ 1.4 billion contract to develop an Avionics Modernization Program kit for the C-130. The program was beset with delays and cost overruns until project restructuring in 2007. In September 2009, it was reported that
12382-416: The cockpit feeling ill. Johnston disconnected the faulty autopilot and manually stabilized the plane "with two slight control movements". Johnston recommended Boeing increase the height of the tail fin , add a boosted rudder as well as add a ventral fin . These modifications were aimed at mitigating Dutch roll by providing more directional stability in yaw . The initial 145-foot-long (44 m) 707-120
12533-417: The database for future derivatives of the C-130. Modifications made to the HTTB included extended chord ailerons, a long chord rudder, fast-acting double-slotted trailing edge flaps, a high-camber wing leading edge extension, a larger dorsal fin and dorsal fins, the addition of three spoiler panels to each wing upper surface, a long-stroke main and nose landing gear system, and changes to the flight controls and
12684-448: The design constraints imposed by limitations of late-1940s jet engines, developing a robust, safe, and high-capacity jet aircraft was within reach for Boeing. Boeing studied numerous wing and engine layouts for its new transport/tanker, some of which were based on the B-47 and C-97, before settling on the 367-80 "Dash 80" quadjet prototype aircraft. Less than two years elapsed from project launch in 1952 to rollout on May 14, 1954, with
12835-513: The fin under the tail became standard on all 707 variants and were retrofitted to all earlier 707s. The 37 -420s were delivered to BOAC, Lufthansa, Air-India , El Al , and Varig through November 1963; Lufthansa was the first to carry passengers, in March 1960. The 707-320B had the application of the JT3D turbofan to the Intercontinental, but with aerodynamic refinements. The wing was modified from
12986-978: The first Gulf War (Operation Desert Storm), Operation Uphold Democracy , the second Gulf War (Operation Iraqi Freedom ) and in Operation Enduring Freedom . The EC-130E was eventually replaced by the EC-130J Commando Solo and retired in 2006. Based on a C-130H airframe, the EC-130H Compass Call is an airborne communications jamming platform operated by the Air Combat Command 's (ACC) 55th Electronic Combat Group (55 ECG) at Davis-Monthan AFB , Tucson, Arizona . The EC-130 Compass Call aircraft attempts to disrupt enemy command and control communications and limits adversary coordination essential for enemy force management. The Compass Call system employs offensive counterinformation and electronic attack capabilities in support of U.S. and Coalition tactical air, surface, and special operations forces . The EC-130H
13137-478: The first Dash 80 flying on July 15, 1954. The prototype was a proof-of-concept aircraft for both military and civilian use. The United States Air Force was the first customer, using it as the basis for the KC-135 Stratotanker aerial refueling and cargo aircraft. Whether the passenger 707 would be profitable was far from certain. At the time, nearly all of Boeing's revenue came from military contracts. In
13288-633: The higher letter) for the TACAMO mission from 1963 until 1993. In October 2024, the US Navy announced that the new C-130J-30-based TACAMO mission aircraft will be designated E-130J . It will replace the currently operational E-6 Mercury in the near future. The EC-130E Commando Solo entered service in 1978 as the EC-130E Coronet Solo with the Tactical Air Command (TAC). In 1983 the Coronet Solo's mission
13439-461: The inboard wing and blown flaps for circulation control on the outboard wing. Lockheed's design also used blown flaps outboard, but inboard used patented reversing ejector nozzles. Boeing's design completed over 2,000 hours of wind tunnel tests in late 2009. It was a 5 percent-scale model of a narrow body design with a 55,000 lb (25,000 kg) payload. When the AFRL increased the payload requirement to 65,000 lb (29,000 kg), they tested
13590-408: The initial 707's wing to help increase range and payload, giving birth to the 707-320. Pan Am inaugurated 707 service with a christening at National Airport on October 17, 1958, attended by President Eisenhower , followed by a transatlantic flight for VIPs (personal guests of founder Juan Trippe ) from Baltimore's Friendship International Airport to Paris. The aircraft's first commercial flight
13741-422: The installation of 1,360 US gallons (5,100 litres) Sargent Fletcher external fuel tanks under each wing's midsection and more powerful Allison T56-A-7A turboprops. The hydraulic boost pressure to the ailerons was reduced back to 2,050 psi (14.1 MPa) as a consequence of the external tanks' weight in the middle of the wingspan. The E model also featured structural improvements, avionics upgrades, and
13892-549: The introduction of the C-130B model in 1959. Some A-models were equipped with skis and re-designated C-130D . As the C-130A became operational with Tactical Air Command (TAC), the C-130's lack of range became apparent and additional fuel capacity was added with wing pylon-mounted tanks outboard of the engines; this added 6,000 pounds (2,700 kg) of fuel capacity for a total capacity of 40,000 pounds (18,000 kg). The C-130B model
14043-499: The jets would bear 700-series numbers, and the first would be the 707. The marketing personnel at Boeing chose 707 because they thought it was more appealing than 700. The project was enabled by the Pratt & Whitney JT3C turbojet engine, the civilian version of the J57 that yielded much more power than the previous generation of jet engines and was proving itself with the B-52. Freed from
14194-622: The last new-build 707 airframes built as E-3 and E-6 aircraft. Traces of the 707 are still found in the 737 , which uses a modified version of the 707's fuselage, as well as the same external nose and cockpit configurations as those of the 707. These were also used on the previous 727 , while the 757 also used the 707 fuselage cross-section. The 707's wings are swept back at 35°, and like all swept-wing aircraft, display an undesirable " Dutch roll " flying characteristic that manifests itself as an alternating combined yawing and rolling motion. Boeing already had considerable experience with this on
14345-428: The last scheduled 707 flight for passengers by a US carrier on October 30, 1983, although 707s remained in scheduled service by airlines from other nations for much longer. Middle East Airlines of Lebanon flew 707s and 720s in front-line passenger service until the end of the 1990s. Since LADE of Argentina removed its 707-320Bs from regular service in 2007, Saha Airlines of Iran was the last commercial operator of
14496-531: The later JT3D-3 version giving 18,000 lbf (80 kN). (This thrust did not require water injection, eliminating both the system and 5000–6000 lb of water.) The -120B had the wing modifications introduced on the 720 and a longer tailplane; a total of 72 were built, 31 for American and 41 for TWA, plus six short-bodied -138Bs for Qantas. American had its 23 surviving -123s converted to -123Bs, but TWA did not convert its 15 -131s. The only other conversions were Pan Am's five surviving -121s and one surviving -139,
14647-459: The launch order for 20 707-121 aircraft by Pan Am and an American Airlines order for 30 707-123 aircraft. The first revenue flight was on October 26, 1958; 56 were built, plus seven short-bodied -138s; the last -120 was delivered to Western in May 1960. The 707-138 was a -120 with a fuselage 10 ft (3.0 m) shorter than the others, with 5 ft (1.5 m) (three frames) removed ahead and behind
14798-407: The massive Convair B-36 Peacemaker bomber but had never been used. The U.S. Army and U.S. Air Force resurrected the huge weapons as a means of clearing landing zones for helicopters and in early 1969 the 463rd commenced Commando Vault missions. Although the stated purpose of Commando Vault was to clear LZs, they were also used on enemy base camps and other targets. During the late 1960s, the U.S.
14949-404: The maximum takeoff weight the same as that of the -120 (247,000 lb (112 t)), the -138 was able to fly the longer routes that Qantas needed. Braniff International Airways ordered the higher-thrust version with Pratt & Whitney JT4 A engines, the 707-220. The final major derivative was the 707-320, which featured an extended-span wing and JT4A engines, while the 707-420 was the same as
15100-456: The mission was 'migrated' to the E-8 JSTARS and E-3 AWACS fleets. The EC-130E Commando Solo was an earlier version of a U.S. Air Force and Air National Guard psychological operations (PSYOPS) aircraft and this aircraft also employed a C-130E airframe, but was modified by using the mission electronic equipment from the retired EC-121S Coronet Solo aircraft. This airframe served during
15251-658: The more sensitive upgraded components. The equivalent model for export to the UK is the C-130K , known by the Royal Air Force (RAF) as the Hercules C.1 . The C-130H-30 ( Hercules C.3 in RAF service) is a stretched version of the original Hercules, achieved by inserting a 100 in (2.5 m) plug aft of the cockpit and an 80 in (2.0 m) plug at the rear of the fuselage. A single C-130K
15402-462: The new jet service StarStream , launching its first jet service, between New York-Idlewild International Airport and San Francisco International Airport , on January 25, 1959. American Airlines was the first domestic airline to fly its own jets, on January 25, 1959. TWA started domestic 707-131 flights in March and Continental Airlines started 707-124 flights in June; airlines that had ordered only
15553-430: The operating life of the sensor pallets. Another mission to the area was planned as Operation Golden Whip, but it was called off in 1970. It is most likely that the aircraft used on this mission was either C-130E serial number 64-0506 or 64-0507 (cn 382-3990 and 382–3991). These two aircraft were delivered to Air America in 1964. After being returned to the U.S. Air Force sometime between 1966 and 1970, they were assigned
15704-435: The operator's insufficient system safety review failed to consider the consequences of the inadequate design to all operating regimes. A factor that contributed to the accident was the flight crew's lack of engineering flight test training. In the 1990s, the improved C-130J Super Hercules was developed by Lockheed (later Lockheed Martin). This model is the newest version and the only model in production. Externally similar to
15855-411: The outer port (number 1) engine mount is distinctly different from the other three, as this engine is not fitted with a turbocompressor. Later-model 707s typically had this configuration, although American Airlines had turbocompressors on engines 2 and 3 only. Early 707 models often had turbocompressor fairings on all four engines, but with only two or three compressors installed. Pratt & Whitney, in
16006-456: The planned Avionics Modernization Program (AMP) upgrade to the older C-130s would be dropped to provide more funds for the F-35, CV-22 and airborne tanker replacement programs. However, in June 2010, Department of Defense approved funding for the initial production of the AMP upgrade kits. Under the terms of this agreement, the USAF has cleared Boeing to begin low-rate initial production (LRIP) for
16157-403: The production models from the prototype. A Krueger flap was installed along the leading edge between the inner and outer engines on early 707-120 and -320 models. This was in response to de Havilland Comet overrun accidents which occurred after over-rotating on take-off. Wing stall would also occur on the 707 with over-rotation so the leading-edge flaps were added to prevent stalling even with
16308-660: The proposal and the company won the contract for the now-designated Model 82 on 2 July 1951. The first flight of the YC-130 prototype was made on 23 August 1954 from the Lockheed plant in Burbank , California. The aircraft, serial number 53-3397 , was the second prototype, but the first of the two to fly. The YC-130 was piloted by Stanley Beltz and Roy Wimmer on its 61-minute flight to Edwards Air Force Base ; Jack Real and Dick Stanton served as flight engineers. Kelly Johnson flew chase in
16459-513: The second day of Operation Odyssey Dawn , an EC-130J warned Libyan shipping "Libyan ships or vessels do not leave port, the Gaddafi regime forces are violating a United Nations resolution ordering the end to the hostilities in your country. If you attempt to leave port, you will be attacked and destroyed immediately. For your own safety do not leave port." The unencrypted message in Arabic, French and English
16610-573: The serial numbers of C-130s that had been destroyed in accidents. 64-0506 is now flying as 62–1843, a C-130E that crashed in Vietnam on 20 December 1965, and 64-0507 is now flying as 63–7785, a C-130E that had crashed in Vietnam on 17 June 1966. The A-model continued in service through the Vietnam War , where the aircraft assigned to the four squadrons at Naha AB , Okinawa, and one at Tachikawa Air Base , Japan performed yeoman's service, including operating highly classified special operations missions such as
16761-437: The standard AM , FM , HF , TV and military communications bands. Missions are flown at the maximum altitudes possible to provide optimum propagation patterns. The EC-130J flies during either day or night scenarios with equal success, and is air-refuelable. A typical mission consists of a single-ship orbit which is offset from the desired target audience. The targets may be either military or civilian personnel. The Commando Solo
16912-443: The tail dragging on the runway. The initial standard model was the 707-120 with JT3C turbojet engines. Qantas ordered a shorter-bodied version called the 707-138, which was a -120 with six fuselage frames removed, three in front of the wings, and three aft. The frames in the 707 were set 20 in (510 mm) apart, so this resulted in a shortening of 10 ft (3.0 m) to a length of 134 ft 6 in (41.0 m). With
17063-427: The three aircraft delivered to the USAF as -153s and the seven short-bodied Qantas -138s (making 13 total 707s delivered to Qantas between 1959 and 1964). The first flight of the -120B was on June 22, 1960, and American carried the first passengers in March 1961; the last delivery was to American in April 1969. Maximum weight was 258,000 lb (117,000 kg) for both the long- and short-bodied versions. The 707-220
17214-468: The time preferred the more established Douglas Aircraft as a maker of passenger aircraft, and several major carriers committed only to the Douglas DC-8, delayed by Douglas' decision to wait for the larger and more fuel efficient ( Pratt & Whitney JT4A ) turbojet to design a larger and longer range aircraft around. Anticipating this advantage, Boeing made a late and costly decision to redesign and enlarge
17365-653: The transport became the fifth aircraft to mark 50 years of continuous service with its original primary customer, which for the C-130 is the United States Air Force (USAF). The C-130 is the longest continuously produced military aircraft, having achieved 70 years of production in 2024. The updated Lockheed Martin C-130J Super Hercules remains in production as of 2024 . The Korean War showed that World War II -era piston-engine transports— Fairchild C-119 Flying Boxcars , Douglas C-47 Skytrains and Curtiss C-46 Commandos —were no longer adequate. On 2 February 1951,
17516-518: The truck routes impassable. In November 1964, on the other side of the globe, C-130Es from the 464th Troop Carrier Wing but loaned to 322d Air Division in France, took part in Operation Dragon Rouge , one of the most dramatic missions in history in the former Belgian Congo . After communist Simba rebels took white residents of the city of Stanleyville hostage, the U.S. and Belgium developed
17667-548: The turboprop configuration chosen for the T56, with the propeller connected to the compressor, had the potential to cause structural failure of the aircraft if an engine failed. Safety devices had to be incorporated to reduce the excessive drag from a windmilling propeller. The Hercules resembles a larger, four-engine version of the Fairchild C-123 Provider with a similar wing and cargo ramp layout. The C-123 had evolved from
17818-515: The type's usefulness in Antarctica , the U.S. Navy purchased several B-models equipped with skis that were designated as LC-130s. C-130B-II electronic reconnaissance aircraft were operated under the SUN VALLEY program name primarily from Yokota Air Base, Japan. All reverted to standard C-130B cargo aircraft after their replacement in the reconnaissance role by other aircraft. The C-130 was also used in
17969-402: The ventral fin to be removed (although the taller fin was retained). The 707-320Bs built after 1963 used the same wing as the -320C and were known as 707-320B Advanced aircraft. In total, 1,010 707s were built for civilian use between 1958 and 1978, though many of these found their way to military service. The 707 production line remained open for purpose-built military variants until 1991, with
18120-480: The vertical fin and upper fuselage not found on other C-130s. Radio call numbers on the tail of these aircraft were regularly changed to confuse observers and disguise their true mission. The extended-range C-130E model entered service in 1962 after it was developed as an interim long-range transport for the Military Air Transport Service. Essentially a B-model, the new designation was the result of
18271-512: The war, and these refueled both the Douglas A-4 Skyhawks and Navy Dassault-Breguet Super Étendards ; some C-130s were modified to operate as bombers with bomb-racks under their wings. The British also used RAF C-130s to support their logistical operations. Boeing 707 The Boeing 707 is an early American long-range narrow-body airliner , the first jetliner developed and produced by Boeing Commercial Airplanes . Developed from
18422-719: The way back, the aircraft refueled in Nairobi , Kenya). During the Falklands War (Spanish: Guerra de las Malvinas ) of 1982, Argentine Air Force C-130s undertook dangerous re-supply night flights as blockade runners to the Argentine garrison on the Falkland Islands . They also performed daylight maritime survey flights. One was shot down by a Royal Navy Sea Harrier using AIM-9 Sidewinders and cannon. The crew of seven were killed. Argentina also operated two KC-130 tankers during
18573-414: The wing (from 138 ft 10 in (42.32 m) to 145 ft 6 in (44.35 m) ), with extensions to the fin and horizontal stabilizer extending the aircraft's length further. The longer wing carried more fuel, increasing range by 1,600 miles (2,600 km) and allowing the aircraft to operate as true transoceanic aircraft. The wing modifications included outboard and inboard inserts, as well as
18724-768: The wing, giving increased range. Maximum takeoff weight was the same 247,000 lb (112,000 kg) as the standard version. It was a variant for Qantas, thus had its customer number 38. To allow for full-load takeoffs at the midflight refueling stop in Fiji, the wing's leading-edge slats were modified for increased lift, and the allowable temperature range for use of full takeoff power was increased by 10°F (5.5°C). Seven -138s were delivered to Qantas between June and September 1959, and they first carried passengers in July of that year. The 707-120B had Pratt & Whitney JT3D-1 turbofan engines, which were quieter, more powerful, and more fuel-efficient, rated at 17,000 lbf (75.6 kN), with
18875-499: The yaw damper was turned off to familiarize the new pilots with flying techniques, a trainee pilot's actions violently exacerbated the Dutch roll motion and caused three of the four engines to be torn from the wings. The plane, a brand new 707-227, N7071 , destined for Braniff, crash-landed on a river bed north of Seattle at Arlington, Washington , killing four of the eight occupants. In his autobiography, test pilot Tex Johnston describes
19026-508: Was shot down over Armenia by four Soviet MiG-17s along the Turkish-Armenian border during a routine mission. Australia became the first non-American operator of the Hercules with 12 examples being delivered from late 1958. The Royal Canadian Air Force became another early user with the delivery of four B-models (Canadian designation CC-130 Mk I) in October / November 1960. In 1963,
19177-484: Was June 1962, with Pan Am. The 707-320B Advanced is an improved version of the -320B, adding the three-section leading-edge flaps already seen on the -320C. These reduced takeoff and landing speeds and altered the lift distribution of the wing, allowing the ventral fin found on earlier 707s to be removed. From 1965, -320Bs had the uprated -320C undercarriage allowing the same 335,000 lb (152,000 kg) MTOW. These were often identified as 707-320BA-H. The 707-320C has
19328-646: Was a land-based naval aviation platform that served as a SIOP strategic communications link aircraft for the U.S. Navy's Fleet Ballistic Missile (FBM) submarine force and as a backup communications link for the USAF manned strategic bomber and intercontinental ballistic missile forces. To ensure survivability, TACAMO operated as a solo platform, well away from and not interacting with other major naval forces such as sea-based aircraft carrier strike groups and their carrier air wings or land-based maritime patrol aircraft. Operated by Fleet Air Reconnaissance Squadron THREE (VQ-3) and Fleet Air Reconnaissance Squadron FOUR (VQ-4),
19479-488: Was a test aircraft used to study the feasibility of using CFM International CFM56 engines on a 707 airframe and possibly retrofitting existing aircraft with the engine. After testing in 1979, N707QT , the last commercial 707 airframe, was restored to 707-320C configuration and delivered to the Moroccan Air Force as a tanker aircraft via a "civilian" order. Boeing abandoned the retrofit program, since they felt it would be
19630-458: Was also deployed during the 2010 Haiti earthquake , broadcasting a recording from Raymond Joseph (Haiti's ambassador to the United States) warning residents not to attempt to flee to the United States by sea. The aircraft also broadcast announcements of where earthquake victims can go for food and aid, news from Voice of America , and instructions on hygiene procedures to prevent disease. On
19781-616: Was awarded the Distinguished Flying Cross for his role in this test series. The tests were highly successful, but the aircraft was not deployed this way. Flatley denied that C-130 was tested for carrier onboard delivery (COD) operations, or for delivering nuclear weapons. He said that the intention was to support the Lockheed U-2 , also being tested on carriers. The Hercules used in the test, most recently in service with Marine Aerial Refueler Squadron 352 ( VMGR-352 ) until 2005,
19932-401: Was designed for hot and high operations with more powerful 15,800 lbf (70.3 kN) Pratt & Whitney JT4A-3 turbojets. Five of these were produced, but only four were ultimately delivered, with one being lost during a test flight. All were for Braniff International Airways and carried the model number 707-227; the first entered service in December 1959. This version was made obsolete by
20083-459: Was designed for transcontinental routes, and often required a refueling stop when flying across the North Atlantic. It had four Pratt & Whitney JT3C-6 turbojets, civilian versions of the military J57, initially producing 13,000 lbf (57.8 kN) with water injection . Maximum takeoff weight was 247,000 lb (112,000 kg) and first flight was on December 20, 1957. Major orders were
20234-543: Was developed to complement the A-models that had previously been delivered, and incorporated new features, particularly increased fuel capacity in the form of auxiliary tanks built into the center wing section and an AC electrical system. Four-bladed Hamilton Standard propellers replaced the Aero Products' three-blade propellers that distinguished the earlier A-models. The C-130B had ailerons operated by hydraulic pressure that
20385-802: Was eager to get information on Chinese nuclear capabilities. After the failure of the Black Cat Squadron to plant operating sensor pods near the Lop Nur Nuclear Weapons Test Base using a U-2, the CIA developed a plan, named Heavy Tea , to deploy two battery-powered sensor pallets near the base. To deploy the pallets, a Black Bat Squadron crew was trained in the U.S. to fly the C-130 Hercules. The crew of 12, led by Col Sun Pei Zhen, took off from Takhli Royal Thai Air Force Base in an unmarked U.S. Air Force C-130E on 17 May 1969. Flying for six and
20536-546: Was established at Ubon Royal Thai Air Force Base , Thailand. After the move to Ubon, the mission became a four-engine FAC mission with the C-130 crew searching for targets and then calling in strike aircraft. Another little-known C-130 mission flown by Naha-based crews was Operation Commando Scarf (or Operation Commando Lava), which involved the delivery of chemicals onto sections of the Ho Chi Minh Trail in Laos that were designed to produce mud and landslides in hopes of making
20687-464: Was from Idlewild Airport , New York, to Le Bourget , Paris, on October 26, 1958, with a fuel stop in Gander, Newfoundland . In December, National Airlines operated the first US domestic jet airline flights between New York/Idlewild and Miami, using 707s leased from Pan Am. In February 1956, rival global giant Trans World Airlines' then-President Howard Hughes ordered eight new Boeing 707-120, dubbing
20838-503: Was increased from 2,050 to 3,000 psi (14.1 to 20.7 MPa ), as well as uprated engines and four-blade propellers that were standard until the J-model. The B model was originally intended to have "blown controls", a system that blows high-pressure air over the control surfaces to improve their effectiveness during slow flight. It was tested on an NC-130B prototype aircraft with a pair of T-56 turbines providing high-pressure air through
20989-486: Was known for its military aircraft. The company had produced innovative and important bombers, from the B-17 Flying Fortress and B-29 Superfortress to the jet-powered B-47 Stratojet and B-52 Stratofortress , but its commercial aircraft were not as successful as those from Douglas Aircraft and other competitors. As Douglas and Lockheed dominated the postwar air transport boom, the demand for Boeing's offering,
21140-683: Was later removed when aerial refueling of helicopters proved safer and more versatile. The movie The Perfect Storm depicts a real-life SAR mission involving aerial refueling of a New York Air National Guard HH-60G by a New York Air National Guard HC-130P. The C-130R and C-130T are U.S. Navy and USMC models, both equipped with underwing external fuel tanks. The USN C-130T is similar but has additional avionics improvements. In both models, aircraft are equipped with Allison T56-A-16 engines. The USMC versions are designated KC-130R or KC-130T when equipped with underwing refueling pods and pylons and are fully night vision system compatible. The RC-130
21291-480: Was lost in a fatal accident on 3 February 1993, at Dobbins Air Reserve Base , in Marietta, Georgia. The crash was attributed to disengagement of the rudder fly-by-wire flight control system, resulting in a total loss of rudder control capability while conducting ground minimum control speed tests (Vmcg). The disengagement was a result of the inadequate design of the rudder's integrated actuator package by its manufacturer;
21442-482: Was not ideally suited for operations with the USAF's new fleets of jet-powered fighters and bombers; this was where Boeing's new design would win military orders. As the first of a new generation of American passenger jets, Boeing wanted the aircraft's model number to emphasize the difference from its previous propeller-driven aircraft, which bore 300-series numbers. The 400-, 500- and 600-series were already used by their missiles and other products, so Boeing decided that
21593-519: Was not the first commercial jetliner in service, the 707 was the first to be widespread, and is often credited with beginning the Jet Age . It dominated passenger air-transport in the 1960s, and remained common through the 1970s, on domestic , transcontinental , and transatlantic flights , as well as cargo and military applications. It established Boeing as a dominant airliner manufacturer with its 7x7 series . The initial, 145-foot-long (44 m) 707-120
21744-418: Was powered by Pratt & Whitney JT3C turbojet engines. The shortened, long-range 707-138 and the more powerful 707-220 entered service in 1959. The longer-range, heavier 707-300/400 series has larger wings and is stretched slightly by 8 feet (2.4 m). Powered by Pratt & Whitney JT4A turbojets, the 707-320 entered service in 1959, and the 707-420 with Rolls-Royce Conway turbofans in 1960. The 720,
21895-543: Was powered by Pratt & Whitney JT3C turbojet engines. The JT3D-3B engines are readily identifiable by the large gray secondary-air inlet doors in the nose cowl. These doors are fully open (sucked in at the rear) during takeoff to provide additional air. The doors automatically close with increasing airspeed. The 707 was the first commercial jet aircraft to be fitted with clamshell-type thrust reversers . The 707 uses engine-driven turbocompressors to supply compressed air for cabin pressurization . On many commercial 707s,
22046-504: Was purchased by the Met Office for use by its Meteorological Research Flight, where it was classified as the Hercules W.2 . This aircraft was heavily modified, with its most prominent feature being the long red and white striped atmospheric probe on the nose and the move of the weather radar into a pod above the forward fuselage. This aircraft, named Snoopy , was withdrawn in 2001 and was then modified by Marshall of Cambridge Aerospace as
22197-606: Was recorded by a ham radio operator in the Netherlands . The EC-130 has been flown in operations against the Islamic State in Iraq to jam their communications. Data from Jane's All the World's Aircraft 2010–11, US Air Force Factsheet General characteristics Performance Related development Related lists Lockheed C-130 Hercules The Lockheed C-130 Hercules
22348-494: Was to be designed specifically as a combat transport with loading from a hinged loading ramp at the rear of the fuselage. A notable advance for large aircraft was the introduction of a turboprop powerplant, the Allison T56 which was developed for the C-130. It gave the aircraft greater range than a turbojet engine as it used less fuel. Turboprop engines also produced much more power for their weight than piston engines. However,
22499-582: Was to be powered by four 22,500-pound-force thrust (100 kN) Pratt & Whitney JT3D-15 turbofan engines, and it would have had a nearly 10-foot (3.0 m) extension in wingspan, to 155.5 feet (47.4 m). Two variations were proposed, the 707-820(505) model and the 707-820(506) model. The 505 model would have had a fuselage 45 feet (14 m) longer than the 707-320B, for a total length of 198.6 feet (60.5 m). This model would have carried 209 passengers in mixed-class configuration and 260 passengers in all-economy configuration. The 506 model would have had
22650-527: Was transferred to the Military Airlift Command (MAC) and redesignated the EC-130E Volant Solo. With the formation of Air Force Special Operations Command , the mission was transferred to AFSOC and redesignated Commando Solo. Operations were consolidated under a single-AFSOC gained unit, the 193d Special Operations Wing (193 SOW) of the Pennsylvania Air National Guard . In the early 1990s
22801-539: Was used extensively in the Gulf War and Operation Iraqi Freedom , disrupting Iraqi communications at both the strategic and tactical levels. It has also been used in Operation Enduring Freedom in Afghanistan and Operation Inherent Resolve against the Islamic State . The EC-130J Commando Solo is a modified C-130J Super Hercules used to conduct psychological operations (PSYOP) and civil affairs broadcast missions in
