252-570: A Boeing B-29 Superfortress and a second aircraft lost when its arrestor hook failed to extend. The Seafire proved more vulnerable to the stresses of carrier operation with many aircraft suffering wrinkling of the rear fuselage brought about by heavy landings. Following the end of operations, when peacetime airworthiness rules were re-imposed, all but three of 800 Squadron's Seafires were declared unserviciable owing to wrinkling. The Royal Canadian Navy and French Aviation Navale obtained Seafires to operate from ex-Royal Navy aircraft carriers following

378-543: A Commander Ermen to fly a Spitfire I. After his first flight in R6718 , Ermen soon learned that Joseph Smith , Chief Designer at Supermarine, had been instructed to fit an "A-frame" arrestor hook on a Spitfire and that this had flown on 16 October; a drawing of this aircraft had been shown to the FAA on 27 October. After further discussions, Supermarine submitted a drawing of a Spitfire with folding wings and an arrestor hook. In this case,

504-508: A Joint Security Area at Panmunjom . The conflict caused more than 1 million military deaths and an estimated 2 to 3 million civilian deaths, a larger proportion of civilian deaths than in World War II or the Vietnam War . Alleged war crimes include the mass killing of suspected communists by Seoul and the torture and starvation of prisoners of war by Pyongyang. North Korea became one of

630-561: A Spitfire F Mk.21 prototype by Cunliffe-Owen and featured a "sting" arrestor hook. Because this version was considered to be an "interim" type the wing, which was unchanged from that of the Spitfire Mk.21, was non-folding. The fuel capacity of this variant was 120 imp gal (550 L) in two main forward fuselage tanks: the lower tank carried 48 imp gal (220 L) while the upper tank carried 36 imp gal (160 L; 43 US gal), plus two fuel tanks built into

756-506: A 10 ft 5 in (3.18 m) Rotol propeller. Designed in response to Specification N.4/43 this appeared to be a naval Spitfire F Mk.XII ; in reality the Mk.XV was an amalgamation of a strengthened Seafire III airframe and wings with the wing fuel tanks, retractable tailwheel, larger elevators and broad-chord "pointed" rudder of the Spitfire VIII. The engine cowling was different from that of

882-465: A 22.5 imp gal (102 L) combat tank carried underneath each wing. In addition a 50 imp gal (230 L) drop tank could be carried under the fuselage. In April 1947, the Griffon 61s or 64s driving a five bladed Rotol propeller unit were replaced with Griffon 85s or 87s driving two three bladed Rotol contra-rotating propellers . All but the first few incorporated larger tail units from

1008-508: A 30 imp gal (140 L) "slipper" fuel tank under the fuselage. In June 1942, the first deliveries of the Seafire took place to 807 Squadron . Another front line unit, 801 Squadron operated this version on board HMS  Furious from October 1942 through to September 1944. The second semi-naval variant of the Seafire and the first to be built as such, was the Seafire F Mk.IIc which

1134-425: A Spitfire F Mk.22 modified to naval standard and featured the cut down rear fuselage and "teardrop" canopy. Again the wing had not been modified to fold. The electrical equipment was changed from a 12 volt system to 24 volts. The fuel system was modified over that of the Seafire 45 to incorporate an extra 32 imp gal (150 L) fuel tank in the rear fuselage, while the wings were plumbed to allow for

1260-459: A Type 72 homing beacon. In these and all subsequent Seafires the instruments were re-calibrated to read kn and nmi rather than mph and mi. The fixed armament was the same as that of the Spitfire Vb; two 20 mm (0.79 in) Hispano Mk.II cannon with 60 rpg fed from a "drum" magazine and four .303 in (7.70 mm) Browning machine guns with 350 rpg. Provision was also made to carry

1386-487: A considerable increase of performance compared to their Merlin-engined predecessors but had serious faults, mainly a result of the increased power of the new engine. The concomitant increase in torque meant the pilot had to continuously correct the flight of the aircraft to prevent the frame of the aircraft rotating in the other direction to that of the propeller. This was a considerable problem when attempting to take off and land from an aircraft carrier. The torque also affected

1512-557: A future independent state. Due to political disagreements and influence from their backers, the zones formed their own governments in 1948. The DPRK was led by Kim Il Sung in Pyongyang , and the ROK by Syngman Rhee in Seoul ; both claimed to be the sole legitimate government of all of Korea and engaged in border clashes as internal unrest was fomented by communist groups in the south. On 25 June 1950,

1638-501: A general attack across the 38th parallel, rather than a limited operation in Ongjin. Kim was concerned that South Korean agents had learned about the plans and that South Korean forces were strengthening their defenses. Stalin agreed to this change. While these preparations were underway in the North, there were clashes along the 38th parallel, especially at Kaesong and Ongjin, many initiated by

1764-526: A meeting with Richard Fairey (of Fairey Aviation ), Fairey proposed that his company could design and build such an aircraft. The idea met with a negative response and the matter was dropped. As a result, the Fleet Air Arm (FAA), at that point still part of the Royal Air Force, was forced into having to order Blackburn Rocs and Gloster Sea Gladiators , both of which proved to be woefully inadequate in

1890-579: A national political constitution on 17 July and elected Syngman Rhee as president on 20 July. The Republic of Korea (South Korea) was established on 15 August 1948. In the Soviet-Korean Zone of Occupation, the Soviets agreed to the establishment of a communist government led by Kim Il Sung. The 1948 North Korean parliamentary elections took place in August. The Soviet Union withdrew its forces in 1948 and

2016-470: A new form of "sting" type arrestor hook was used; this version was attached to the reinforced rudder post at the rear of the fuselage and was housed in a fairing below the base of the shortened rudder. A vee-shaped guard forward of the tailwheel prevented arrestor wires getting tangled up with the tailwheel. 390 Seafire XVs were built by Cunliffe-Owen and Westland from late 1944. Six prototypes had been built by Supermarine. One problem which immediately surfaced

2142-492: A pressing need to replace various obsolete types in the Fleet Air Arm (FAA), some opposed the idea, including as Winston Churchill , although these disputes were often a result of the overriding priority for land-based Spitfires instead. During 1941 and early 1942, the Admiralty again requested naval Spitfires, resulting in an initial batch of Seafire Mk.Ib fighters in late 1941, which were mainly used to gain experience operating

2268-834: A result, the handling of the aircraft suffered. Eventually most of these problems were resolved in Seafire 47 when the six-bladed contra-rotating propeller was adopted. During 1942 and into 1943, FAA squadrons progressively converted to the Seafire, eventually replacing the Sea Hurricane in front-line service. In the Fleet Air Arm, Spitfires and Seafires were used by a number of squadrons, the Spitfires used by training and land based squadrons. Twelve 800 series squadrons used Spitfires and Seafires (Numbers 801 NAS , 802 NAS , 808 NAS , 809 NAS , 879 NAS , 880 NAS , 884 NAS , 885 NAS , 886 NAS , 887 NAS , 897 NAS and 899 NAS ). Several units of

2394-598: A telegram. Mao accepted the decision made by Kim and Stalin to unify Korea but cautioned Kim over possible US intervention. Soviet generals with extensive combat experience from World War II were sent to North Korea as the Soviet Advisory Group. They completed plans for attack by May and called for a skirmish to be initiated in the Ongjin Peninsula on the west coast of Korea. The North Koreans would then launch an attack to capture Seoul and encircle and destroy

2520-556: A total of 48 Spitfire Mk.Vb were converted by Air Training Service Ltd. at Hamble to become "hooked Spitfires". This was the Seafire Mk.Ib and would be the first of several Seafire variants to reach the Fleet Air Arm. This version of the Seafire was mainly used to allow the Royal Navy to gain experience in operating the Spitfire on aircraft carriers . The main structural change was made to

2646-512: Is overrun by unprovoked armed attack would start a disastrous chain of events leading most probably to world war." While there was hesitance by some in the US government to get involved, considerations about Japan fed into the decision to engage on behalf of South Korea. After the fall of China to the communists, US experts saw Japan as the region's counterweight to the Soviet Union and China. While there

2772-474: The L Mk.IIc powered by a low altitude Merlin 32 specifically manufactured for naval use. This version of the Merlin used a "cropped" supercharger impellor to provide greater power at low altitudes than the standard engines; delivering 1,585 hp (1,182 kW) at 2,750 ft (840 m). Both engines drove a four bladed 10 ft 9 in (3.28 m) diameter Rotol propeller. Because this version used

2898-470: The Cold War between the Soviet Union and US. Fighting ended in 1953 with an armistice but no peace treaty , leading to the ongoing Korean conflict characterized by phases of diplomacy and confrontation. After the end of World War II in 1945, Korea, which had been a Japanese colony for 35 years, was divided by the Soviet Union and the US into two occupation zones at the 38th parallel , with plans for

3024-639: The Fairey Firefly following the outbreak of the Korean War , HMS Triumph was diverted to operations to try to stem the North Korean offensive, Seafires were engaged in performing ground attack and combat air patrols from July until September 1950, when HMS Triumph was replaced by HMS  Theseus , equipped with the newer Hawker Sea Furys . During operations off Korea, Seafires flew 360 operational sorties, losing one aircraft shot down by friendly fire from

3150-685: The German battleship Tirpitz . In June 1944, multiple Seafire squadrons were used during the Normandy landings for the purpose of locating in-land targets for naval gunnery batteries to attack; during this operation, these aircraft had been placed under RAF control and were operated from shore bases, these were returned to FAA control in July 1944. In August 1944, Seafires were used to support Allied ground forces during Operation Dragoon in Southern France. During

3276-526: The Korean People's Army (KPA), equipped and trained by the Soviets, launched an invasion of the south. In the absence of the Soviet Union's representative, the UN Security Council denounced the attack and recommended member states to repel the invasion. UN forces comprised 21 countries, with the US providing around 90% of military personnel. Seoul was captured on 28 June, and by early August,

3402-660: The Republic of Korea Army (ROKA) and its allies were nearly defeated, holding onto only the Pusan Perimeter in the peninsula's southeast. On 15 September, UN forces landed at Inchon near Seoul, cutting off KPA troops and supply lines. UN forces broke out from the perimeter on 18 September, re-captured Seoul, and invaded North Korea in October, capturing Pyongyang and advancing towards the Yalu River —the border with China. On 19 October,

3528-589: The Royal Naval Volunteer Reserve also flew Seafires postwar, including 1831, 1832 and 1833 squadrons. In November 1942, the first combat use of the Seafire occurred during Operation Torch , the Allied landings in North Africa , from the decks of several escort and fleet carriers; unusually, Seafires flew with American star markings during the operation, these were removed following their withdrawal from

3654-464: The Spiteful and Seafang . These two changes transformed the handling by eliminating the swing to starboard of previous Griffon engined variants. 200 of the Mk.46s were ordered but only 24 were built, all by Supermarine. The final version of the Seafire was the Seafire F Mk.47 and FR Mk.47 . There was no true prototype, instead the first production aircraft PS944 and PS945 served as trials aircraft. As

3780-701: The Supermarine Spitfire fighter adapted for operation from aircraft carriers . It was analogous in concept to the Hawker Sea Hurricane , a navalised version of the Spitfire's stablemate, the Hawker Hurricane . The name Seafire was derived from the contraction of the full name of Sea Spitfire . A carrier-capable version of the Supermarine Spitfire had been proposed by the Admiralty in May 1938. Despite

3906-588: The Viet Minh before being withdrawn from combat operations in January 1949. After returning to European waters, the Seafire units were re-equipped with Seafire XVs but these were quickly replaced by Grumman F6F Hellcats from 1950. The Irish Air Corps operated Seafires for a time after the war, despite having no naval air service nor aircraft carriers. The aircraft were operated from Baldonnel (Casement Aerodrome) with most of their naval equipment removed, but retaining

4032-654: The atomic bombing of Hiroshima . By 10 August, the Red Army had begun to occupy the north of Korea. On 10 August in Washington , US Colonels Dean Rusk and Charles H. Bonesteel III were assigned to divide Korea into Soviet and US occupation zones and proposed the 38th parallel as the dividing line. This was incorporated into the US General Order No. 1 , which responded to the Japanese surrender on 15 August. Explaining

4158-690: The "C" wing the Hispano cannon were fed from a 120-round belt magazine, otherwise the armament was the same as that of the Ib; the FR also carried two F24 cameras . After trials of Rocket Assisted Take Off Gear ( RATOG - small solid-fuel rocket motors which could be attached to the fuselage or wings of aircraft to help shorten the take-off run) in February 1943, this equipment became a standard fitting available for all Seafires. However, many FAA pilots rarely used RATOG, in part as there

4284-476: The "definitive" carrier based Seafire, the Mk.47 incorporated several refinements over earlier variants. After the first four aircraft, with manually folded wings, the Mk.47 incorporated hydraulically powered wing folding, the outer wings folding upwards in one piece, without the folding wingtips of earlier marks. All Mk.47s adopted the Rotol contra-rotating propellers. The Mk.47 also featured a long supercharger air-duct,

4410-425: The "first generation" Griffon-engine Seafires were to use RATOG at sea unless they were ranged forward of the first crash barrier on deck. The Seafire F Mk.XVII was a modified Mk.XV; the most important change was the reinforced main undercarriage which used longer oleos and a lower rebound ratio. This went some way towards taming the deck behaviour of the Mk.XV, reduced the propensity of the propeller tips "pecking"

4536-639: The 38th parallel and establishing English as the official language during military control. On 8 September, US Lieutenant General John R. Hodge arrived in Incheon to accept the Japanese surrender south of the 38th parallel. Appointed as military governor, Hodge directly controlled South Korea as head of the United States Army Military Government in Korea (USAMGIK 1945–48). In December 1945, Korea

4662-468: The 38th parallel. Armistice negotiations began in July 1951, but dragged on as the fighting became a war of attrition and the north suffered heavy damage from U.S. bombing . Combat ended on 27 July 1953 with the signing of the Korean Armistice Agreement , which allowed the exchange of prisoners and created a 4-kilometre (2.5 mi) wide Demilitarized Zone (DMZ) along the frontline, with

4788-620: The Chinese People's Volunteer Army (PVA) crossed the Yalu and entered the war on the side of the north. UN forces retreated from North Korea in December, following the PVA's first and second offensive . Communist forces captured Seoul again in January 1951 before losing it to a UN counter-offensive two months later. After an abortive Chinese spring offensive , UN forces retook territory roughly up to

4914-687: The Chinese Civil War, while US forces remained stationed in South Korea. By spring 1950, he believed that the strategic situation had changed: PLA forces under Mao Zedong had secured final victory, US forces had withdrawn from Korea, and the Soviets had detonated their first nuclear bomb , breaking the US monopoly. As the US had not directly intervened to stop the communists in China, Stalin calculated they would be even less willing to fight in Korea, which had less strategic significance. The Soviets had cracked

5040-687: The Chinese PLA during the war. North Korea also provided the Chinese Communists in Manchuria with a safe refuge for non-combatants and communications with the rest of China. The North Korean contributions to the Chinese Communist victory were not forgotten after the creation of the People's Republic of China (PRC) in 1949. As a token of gratitude, between 50,000 and 70,000 Korean veterans who served in

5166-572: The German and Italian land-based fighters they were occasionally required to operate against; thus, the need for more capable aircraft was readily apparent. As the Hawker Hurricane had quickly proven to be adaptable to carrier-based operations, there was considerable interest in navalising the Spitfire as well. The matter of a seaborne Spitfire was raised again in November 1939 when the Air Ministry allowed

5292-601: The Griffon 87, but the rest of the 89 production aircraft (built by Supermarine at South Marston) were powered by the Griffon 88, which used a Rolls-Royce fuel-injection system instead of the carburettor used on earlier Spitfires and Seafires. The Seafire 47 saw action with 800 Squadron on board HMS  Triumph during the Malayan Emergency of 1949 and during the Korean War in 1950. However, in 1951 all Seafires were withdrawn from front-line service. In all 90 F Mk.47s and FR Mk.47s were built, all by Supermarine. VR971,

5418-702: The Hellcats and Corsairs of the Fleet) the Seafires were allocated the vital defensive duties of Combat Air Patrol (CAP) over the fleet. During May 1945, Seafires were used to cover the Allied landings at Rangoon for Operation Crimson . Seafires were thus heavily involved in countering the kamikaze attacks during the Okinawa landings and beyond. The Seafire was operational in the Pacific Fleet right up to VJ Day , being used off

5544-474: The North. On 28 June, Rhee ordered the massacre of suspected political opponents in his own country. In five days, the ROK, which had 95,000 troops on 25 June, was down to less than 22,000 troops. In early July, when US forces arrived, what was left of the ROK was placed under US operational command of the United Nations Command . The Truman administration was unprepared for the invasion. Korea

5670-622: The PLA were sent back along with their weapons, and they later played a significant role in the initial invasion of South Korea. China promised to support the North Koreans in the event of a war against South Korea. By 1948, a North Korea-backed insurgency had broken out in the southern half of the peninsula. This was exacerbated by the undeclared border war between the Koreas, which saw division-level engagements and thousands of deaths on both sides. The ROK

5796-547: The ROK had 98,000 soldiers (65,000 combat, 33,000 support), no tanks (they had been requested from the U.S. military, but requests were denied), and a 22-plane air force comprising 12 liaison-type and 10 AT-6 advanced-trainer airplanes. Large U.S. garrisons and air forces were in Japan, but only 200–300 U.S. troops were in Korea. At dawn on 25 June 1950, the KPA crossed the 38th parallel behind artillery fire. It justified its assault with

5922-524: The ROK. The final stage would involve destroying South Korean government remnants and capturing the rest of South Korea, including the ports. On 7 June 1950, Kim called for a Korea-wide election on 5–8 August 1950 and a consultative conference in Haeju on 15–17 June. On 11 June, the North sent three diplomats to the South as a peace overture, which Rhee rejected outright. On 21 June, Kim revised his war plan to involve

6048-418: The ROKA launched a three-pronged assault on the insurgents in South Cholla and Taegu . By March 1950, the ROKA claimed 5,621 guerrillas killed or captured and 1,066 small arms seized. This operation crippled the insurgency. Soon after, North Korea made final attempts to keep the uprising active, sending battalion-sized units of infiltrators under the commands of Kim Sang-ho and Kim Moo-hyon. The first battalion

6174-423: The Seafire provided air cover for the Allied invasion of Sicily , and again in September 1943 during the Allied invasion of Italy . During 1944, large numbers provided air support to ground forces during the Normandy landings and Operation Dragoon in southern France. During the latter half of 1944, Seafire joined the British Pacific Fleet , where it intercepted kamikaze attacks which had become common during

6300-428: The Seafires on landing. Many aircraft missed picking up the arrestor wires and flew into the crash barriers while others had their arrestor hooks pulled off the fuselage because they caught the wires at too high a speed. In spite of these problems, the Seafires (especially the L Mk.IIs and L Mk.IIIs, with their low altitude Merlin engines) patrolled over the carrier fleet as protection against low altitude attackers, while

6426-426: The South Korean interior intensified; persistent operations, paired with worsening weather, denied the guerrillas sanctuary and wore away their fighting strength. North Korea responded by sending more troops to link up with insurgents and build more partisan cadres; North Korean infiltrators had reached 3,000 soldiers in 12 units by the start of 1950, but all were destroyed or scattered by the ROKA. On 1 October 1949,

6552-422: The South from 5,000 to 1,000. However, Kim Il Sung believed widespread uprisings had weakened the South Korean military and that a North Korean invasion would be welcomed by much of the South Korean population. Kim began seeking Stalin's support for an invasion in March 1949, traveling to Moscow to persuade him. Stalin initially did not think the time was right for a war in Korea. PLA forces were still embroiled in

6678-435: The South, armed by the U.S. military with mostly small arms, but no heavy weaponry. Several generals, such as Lee Kwon-mu , were PLA veterans born to ethnic Koreans in China. While older histories of the conflict often referred to these ethnic Korean PLA veterans as being sent from northern Korea to fight in the Chinese Civil War before being sent back, recent Chinese archival sources studied by Kim Donggill indicate that this

6804-617: The South. The ROK was being trained by the US Korean Military Advisory Group (KMAG). On the eve of the war, KMAG commander General William Lynn Roberts voiced utmost confidence in the ROK and boasted that any North Korean invasion would merely provide "target practice". For his part, Syngman Rhee repeatedly expressed his desire to conquer the North, including when US diplomat John Foster Dulles visited Korea on 18 June. Though some South Korean and US intelligence officers predicted an attack, similar predictions had been made before and nothing had happened. The Central Intelligence Agency noted

6930-592: The Soviet Union would not move against US forces in Korea. The Truman administration believed it could intervene in Korea without undermining its commitments elsewhere. On 25 June 1950, the United Nations Security Council unanimously condemned the North Korean invasion of South Korea with Resolution 82 . The Soviet Union, a veto-wielding power , had boycotted Council meetings since January 1950, protesting Taiwan 's occupation of China's permanent seat . The Security Council, on 27 June 1950, published Resolution 83 recommending member states provide military assistance to

7056-432: The Spitfire XII series, being secured with a larger number of fasteners and lacking the acorn shaped blister behind the spinner. The final 30 Mk.XVs were built with the blown "teardrop" cockpit canopy and cut down rear fuselage introduced on the Spitfire Mk.XVI. On the first 50 aircraft manufactured by Cunliffe-Owen a heavier, strengthened A-frame arrestor hook was fitted to cope with the greater weight. On subsequent Mk.XVs

7182-428: The UK, and the US decided that "in due course, Korea shall become free and independent". At the Tehran Conference in 1943 and the Yalta Conference in February 1945, the Soviet Union promised to join its allies in the Pacific War within three months of the victory in Europe . Germany officially surrendered on 8 May 1945, and the USSR declared war on Japan and invaded Manchuria on 8 August 1945, two days after

7308-440: The US in 1949. With the end of the war with Japan , the Chinese Civil War resumed in earnest between the Communists and the Nationalist -led government. While the Communists were struggling for supremacy in Manchuria, they were supported by the North Korean government with matériel and manpower. According to Chinese sources, the North Koreans donated 2,000 railway cars worth of supplies while thousands of Koreans served in

7434-460: The USAMGIK declared martial law . Citing the inability of the Joint Commission to make progress, the US government decided to hold an election under UN auspices to create an independent Korea. The Soviet authorities and Korean communists refused to cooperate on the grounds it would not be fair, and many South Korean politicians boycotted it. The 1948 South Korean general election was held in May. The resultant South Korean government promulgated

7560-552: The aircraft's stall characteristics meant that it was difficult to land accurately on the carrier, resulting in many accidents. Other problems included the Spitfire's short range and endurance (acceptable for an interceptor but not for carrier operations), limited weapons load and that it was dangerous to ditching . The first Seafire variant to overcome many of these problems was the Mk.XVII with its new undercarriage design, reinforced structure and extra fuel tanks, although there were still some compromises and it entered service well after

7686-420: The area to that end. The Truman administration still refrained from committing troops on the ground, because advisers believed the North Koreans could be stopped by air and naval power alone. The Truman administration was uncertain whether the attack was a ploy by the Soviet Union, or just a test of US resolve. The decision to commit ground troops became viable when a communiqué was received on 27 June indicating

7812-428: The area". As Rusk's comments indicate, the US doubted whether the Soviets would agree. Joseph Stalin , however, maintained his wartime policy of cooperation, and on 16 August, the Red Army halted at the 38th parallel for three weeks to await the arrival of US forces. On 7 September 1945, General Douglas MacArthur issued Proclamation No. 1 to the people of Korea, announcing US military control over Korea south of

7938-417: The border, starting in May 1949. Border clashes between South and North continued on 4 August 1949, when thousands of North Korean troops attacked South Korean troops occupying territory north of the 38th parallel. The 2nd and 18th ROK Infantry Regiments repulsed attacks in Kuksa-bong, and KPA troops were "completely routed". Border incidents decreased by the start of 1950. Meanwhile, counterinsurgencies in

8064-443: The border, these guerrillas launched an offensive in September aimed at undermining the South Korean government and preparing the country for the KPA's arrival in force. This offensive failed. However, the guerrillas were now entrenched in the Taebaek-san region of the North Gyeongsang Province and the border areas of the Gangwon Province . While the insurgency was ongoing, the ROKA and KPA engaged in battalion-sized battles along

8190-487: The choice of the 38th parallel, Rusk observed, "Even though it was further north than could be realistically reached by U. S. [ sic ] forces in the event of Soviet disagreement ... we felt it important to include the capital of Korea in the area of responsibility of American troops". He noted that he was "faced with the scarcity of U.S. forces immediately available and time and space factors which would make it difficult to reach very far north before Soviet troops could enter

8316-418: The circumstances in which they were subsequently used. Upon the outbreak of the Second World War , many of the aircraft operated by the FAA had been designed on the assumption that, Germany possessing no aircraft carriers, overall performance was to be of a secondary nature compared to the other duties required, such as observation and spotting, but, by 1941, these aircraft had become obsolete in comparison to

8442-434: The claim ROK troops attacked first and that the KPA were aiming to arrest and execute the "bandit traitor Syngman Rhee". Fighting began on the strategic Ongjin Peninsula in the west. There were initial South Korean claims that the 17th Regiment had counterattacked at Haeju; some scholars argue the claimed counterattack was instead the instigating attack, and therefore that the South Koreans may have fired first. However,

8568-426: The coast of Japan during the final months of the war. The Seafires' best day was 15 August 1945, shooting down eight attacking aircraft for one loss. During the campaign 887 NAS claimed 12 kills and 894 NAS claimed 10 kills (with two more claims earlier in 1944 over Norway ). The top scoring Seafire pilot of the war was Sub-Lieutenant R.H. Reynolds DSC of 894, who claimed 4.5 air victories in 1944–5. During

8694-466: The codes used by the US to communicate with their embassy in Moscow , and reading dispatches convinced Stalin that Korea did not have the importance to the US that would warrant a nuclear confrontation. Stalin began a more aggressive strategy in Asia based on these developments, including promising economic and military aid to China through the Sino-Soviet Treaty of Friendship, Alliance and Mutual Assistance . In April 1950, Stalin permitted Kim to attack

8820-412: The communist victory in the Chinese Civil War, ethnic Korean units in the PLA were sent to North Korea. In the fall of 1949, two PLA divisions composed mainly of Korean-Chinese troops (the 164th and 166th ) entered North Korea, followed by smaller units throughout the rest of 1949. The reinforcement of the KPA with PLA veterans continued into 1950, with the 156th Division and several other units of

8946-406: The country. The Provisional Government of the Republic of Korea was founded in 1919 in Nationalist China . It failed to achieve international recognition, failed to unite the nationalist groups, and had a fractious relationship with its US-based founding president, Syngman Rhee . From 1919 to 1925 and beyond, Korean communists led internal and external warfare against the Japanese. In China,

9072-403: The deck during an arrested landing and the softer oleos stopped the aircraft from occasionally bouncing over the arrestor wires and into the crash barrier. Most production XVIIs had the cut down rear fuselage and teardrop canopy (the windscreen was modified to a rounded section, with narrow quarter windows, rather than the flat windscreen used on Spitfires) and an extra 33 gallon fuel tank fitted in

9198-619: The defense of Italy and Greece, and the country was first on the list of the National Security Council 's post-North Korea invasion list of "chief danger spots". Truman believed if aggression went unchecked, a chain reaction would start that would marginalize the UN and encourage communist aggression elsewhere. The UN Security Council approved the use of force to help the South Koreans, and the US immediately began using air and naval forces in

9324-419: The design was a compromise and suffered many losses through structural damage that was inflicted by heavy landings on carrier decks: a problem that continued even with the strengthening introduced by the Mk.II. The Seafire had a narrow undercarriage track, which meant that it was not well suited to deck operations. The many modifications had shifted the centre-of-gravity aft, making low-speed control difficult and

9450-509: The economic and military aid promised by the Soviets. Kathryn Weathersby cites Soviet documents which said Kim secured Mao's support. Along with Mark O'Neill, she says this accelerated Kim's war preparations. Chen Jian argues Mao never seriously challenged Kim's plans and Kim had every reason to inform Stalin that he had obtained Mao's support. Citing more recent scholarship, Zhao Suisheng contends Mao did not approve of Kim's war proposal and requested verification from Stalin, who did so via

9576-559: The end of the Second World War. Canada's Seafire Mk.XVs were flown from HMS  Warrior and then HMCS  Magnificent before being replaced by Sea Furies in 1948. France received 65 Seafire Mk.IIIs, 24 of these being deployed on the carrier Arromanches in 1948 when it sailed for Vietnam to fight in the First Indochina War , the Seafires operating from land bases and from Arromanches on ground attack missions against

9702-470: The final years of the Pacific War. The Seafire continued to be used after the end of the war, but the FAA withdraw all its Merlin -powered Seafires and replaced them with Griffon -powered counterparts. The type saw further combat use during the Korean War , in which FAA Seafires performed hundreds of missions in the ground attack and combat air patrol roles against North Korean forces in 1950. The Seafire

9828-468: The folding wings needed to allow them to be used on board some Royal Navy carriers, some of which had small aircraft elevators unable to accommodate the full wingspan of the Seafires. The Seafire F Mk.III was the first true carrier adaptation of the Spitfire design. It was developed from the Seafire Mk.IIc, but incorporated manually folding wings allowing more of these aircraft to be spotted on deck or in

9954-653: The folding wings. During the 1950s, an unsuccessful attempt to recycle the Merlin engines was made, by replacing the ailing Bedford engine in a Churchill tank with an engine from a scrapped Seafire. On 19 June 1954, the last Spitfire in Irish service was withdrawn.

10080-459: The former Fourth Field Army arriving in February; the PLA 156th Division was reorganized as the KPA 7th Division. By mid-1950, between 50,000 and 70,000 former PLA troops had entered North Korea, forming a significant part of the KPA's strength on the eve of the war's beginning. The combat veterans and equipment from China, the tanks, artillery, and aircraft supplied by the Soviets, and rigorous training increased North Korea's military superiority over

10206-512: The gap until the Fulmar's replacement (Specification N.5/40 – which would be the Fairey Firefly ) was able to enter service, it was decided to instead order a number of Grumman Wildcats from America to equip the FAA. These aircraft would enter service towards the end of 1940 as the Martlet . During late 1941 and early 1942, the Admiralty again assessed the Spitfire for possible conversion. In late 1941,

10332-519: The government and between 2,976 and 3,392 deaths. By May 1949, both uprisings had been crushed. Insurgency reignited in the spring of 1949 when attacks by guerrillas in the mountainous regions (buttressed by army defectors and North Korean agents) increased. Insurgent activity peaked in late 1949 as the ROKA engaged so-called People's Guerrilla Units. Organized and armed by the North Korean government, and backed by 2,400 KPA commandos who had infiltrated through

10458-576: The government in the South, under the condition that Mao would agree to send reinforcements if needed. For Kim, this was the fulfillment of his goal to unite Korea. Stalin made it clear Soviet forces would not openly engage in combat, to avoid a direct war with the US Kim met with Mao in May 1950 and differing historical interpretations of the meeting have been put forward. According to Barbara Barnouin and Yu Changgeng, Mao agreed to support Kim despite concerns of American intervention, as China desperately needed

10584-618: The government. At 02:00 on 28 June the ROK blew up the Hangang Bridge across the Han River in an attempt to stop the KPA. The bridge was detonated while 4,000 refugees were crossing it, and hundreds were killed. Destroying the bridge trapped many ROK units north of the river. In spite of such desperate measures, Seoul fell that same day. Some South Korean National Assemblymen remained in Seoul when it fell, and 48 subsequently pledged allegiance to

10710-462: The hangars below. Supermarine devised a system of two straight chordwise folds; a break was introduced immediately outboard of the wheel-wells from which the wing hinged upwards and slightly angled towards the fuselage. A second hinge at each wingtip join allowed the tips to fold down (when the wings were folded the wingtips were folded outwards). This version used the more powerful Merlin 55 ( F Mk.III and FR Mk.III ) or Merlin 55M ( L Mk.III ), driving

10836-495: The immediate post-war service, the Fleet Air Arm quickly replaced its Merlin-powered Seafires with Griffon-powered counterparts. Accordingly, the service initially adopted the Seafire Mk.XV and Mk.17; from 1948, the FAA began accepting the definitive model of the Seafire, the Mk.47. In 1950, HMS Triumph started a tour of the Far East, embarking 800 Naval Air Squadron with Seafire 47s along with 827 Naval Air Squadron equipped with

10962-749: The influence of China over Korea in the First Sino-Japanese War (1894–95), ushering in the short-lived Korean Empire . A decade later, after defeating Imperial Russia in the Russo-Japanese War , Japan made the Korean Empire its protectorate with the Eulsa Treaty in 1905, then annexed it with the Japan–Korea Treaty of 1910 . The Korean Empire fell, and Korea was directly ruled by Japan between 1910–45. Many Korean nationalists fled

11088-854: The insurgent war and border clashes. The first socialist uprising occurred without direct North Korean participation, though the guerrillas still professed support for the northern government. Beginning in April 1948 on Jeju Island , the campaign saw arrests and repression by the South Korean government in the fight against the South Korean Labor Party, resulting in 30,000 violent deaths, among them 14,373 civilians, of whom ~2,000 were killed by rebels and ~12,000 by ROK security forces. The Yeosu–Suncheon rebellion overlapped with it, as several thousand army defectors waving red flags massacred right-leaning families. This resulted in another brutal suppression by

11214-498: The intake of which started just behind the spinner and a modified curved windscreen, similar to that used on the Mk.XVII. Other features unique to the Mk.47s were spring-loaded elevator tabs, a large inertia weight in the elevator control system and beading on the trailing edges of the elevators. These changes improved longitudinal stability, especially when the aircraft was fully loaded. The modified windscreen proved to be unpopular with pilots because of continual problems with misting and

11340-493: The invasion force, the North had 114 fighters, 78 bombers, 105 T-34-85 tanks, and some 30,000 soldiers stationed in reserve in North Korea. Although each navy consisted of only several small warships, the North and South Korean navies fought in the war as seaborne artillery for their armies. In contrast, the South Korean population was estimated at 20 million, but its army was unprepared and ill-equipped. As of 25 June 1950,

11466-478: The last of the 22,000 aircraft built under the Spitfire/Seafire program, left the production line at Supermarine on 28 January 1949. The maximum level speed for this mark was: 451mph at 20,000ft or 433mph at 24,000ft, ceiling: 43,100ft, range: 405 miles plus 15 minutes combat. The Spitfire's original role, in which it proved formidable, was that of short-range land-based interceptor. As a carrier based fighter,

11592-735: The latter half of the war, the Seafire saw increasing service as part of Britain's contribution to the Far East Pacific campaigns, serving with No. 887 and 894 Squadrons, Fleet Air Arm , aboard HMS  Indefatigable and joining the British Pacific Fleet late in 1944. As range quickly became a detrimental factor in Pacific operations, Seafires in this theatre were often fitted with additional fuel tanks previously used by Curtiss P-40 Warhawks . Due to their good high altitude performance and lack of ordnance-carrying capabilities (compared to

11718-504: The leading edges of the wings with capacities of 12.5 and 5.5 imp gal (57 and 25 L) respectively. The Seafire F Mk.45 entered service with 778 Squadron in November 1946 and a few were modified to FR Mk.45s in March 1947 by being fitted with two F24 cameras in the rear fuselage. Fifty F Mk.45s were built by the Castle Bromwich factory. The Seafire F Mk.46 and FR Mk.46 was

11844-411: The lift of the right wing (the Griffon engines rotated anti-clockwise) which would lose lift and even stall at moderate speeds. The increased weight of the engine meant that the take-off had to be longer, which proved very dangerous from most British carriers. The increased weight of the engine further affected the centre of gravity that Mitchell had concentrated on so carefully in the original Spitfire. As

12096-734: The longer range fighters, such as the Grumman F6F Hellcat , took on a similar role further out and at higher altitudes. The Seafire II outperformed the A6M-5 Zero at low altitudes when the two types were tested against each other. Contemporary Allied aircraft which had been specifically designed for carrier use, such as the Grumman F6F Hellcat, were considerably larger and more robust. The more powerful Seafire III enjoyed better climb rates and acceleration than these other fighters. Late-war Seafire models equipped with Griffon engines enjoyed

12222-610: The lower rear fuselage which incorporated an A-frame style arrestor hook and strengthened lower longerons . It was soon discovered that the fuselage, especially around hatches, was too weak for carrier operations. In an attempt to alleviate this condition, reinforcing strips were riveted around hatch openings and along the main fuselage longerons. A further 118 Seafire Mk.Ibs incorporating the fuselage reinforcements were modified from Spitfire Vbs by Cunliffe-Owen at Eastleigh and Air Training Service. These aircraft were equipped with Naval HF radio equipment and IFF equipment as well as

12348-429: The most heavily bombed countries in history, and virtually all of Korea's major cities were destroyed. No peace treaty has been signed, making the war a frozen conflict . In South Korea, the war is usually referred to as the "625 War" ( 6·25 전쟁 ; 六二五戰爭 ), the "625 Upheaval" ( 6·25 동란 ; 六二五動亂 ; yugio dongnan ), or simply "625", reflecting the date of its commencement on 25 June. In North Korea,

12474-465: The much lighter Merlin engined Spitfires, meaning that the swing was often accompanied by a series of hops. As an interim measure it was recommended that pilots avoid using full power on take-off (+10 lb (4.5 kg) "boost" maximum was recommended). There were also problems involved with this swing being strongly accentuated in the event of an asymmetric firing of the RATOG equipment. In the event, none of

12600-541: The nationalist National Revolutionary Army and the communist People's Liberation Army (PLA) helped organize Korean refugees against the Japanese military, which had also occupied parts of China. The Nationalist-backed Koreans, led by Yi Pom-Sok , fought in the Burma campaign (1941-45). The communists, led by, among others, Kim Il Sung , fought the Japanese in Korea and Manchuria . At the Cairo Conference in 1943, China,

12726-464: The operation was conducted under the auspices of the UN. It has been sometimes referred to in the English-speaking world as "The Forgotten War" or "The Unknown War" because of the lack of public attention it received during and afterward, relative to the global scale of World War II, which preceded it, and the subsequent angst of the Vietnam War , which succeeded it. Imperial Japan diminished

12852-440: The rear fuselage. The wings were reinforced, with a stronger mainspar necessitated by the new undercarriage, and they were able to carry heavier underwing loads than previous Seafire variants. 232 of this variant were built by Westland (212) and Cunliffe-Owen(20). The Seafire F Mk.45 and FR Mk.45 was the first to use a Griffon 60 series engine with a two-stage, two speed supercharger. The prototype TM379 had been modified from

12978-490: The report that contained the Haeju claim contained errors and outright falsehoods. KPA forces attacked all along the 38th parallel within an hour. The KPA had a combined arms force including tanks supported by heavy artillery. The ROK had no tanks, anti-tank weapons, or heavy artillery. The South Koreans committed their forces in a piecemeal fashion, and these were routed in a few days. On 27 June, Rhee evacuated Seoul with some of

13104-491: The same four-bladed propeller unit used by the IIc series; the Merlin 55M was another version of the Merlin for maximum performance at low altitude. Other modifications that were made on the Spitfire made their way to the Seafire as well including a slim Aero-Vee air filter and six-stack ejector type exhausts. The shorter barrelled, lightweight Hispano Mk.V cannon were introduced during production as were overload fuel tank fittings in

13230-494: The southward movement by the KPA but assessed this as a "defensive measure" and concluded an invasion was "unlikely". On 23 June UN observers inspected the border and did not detect that war was imminent. Chinese involvement was extensive from the beginning, building on previous collaboration between the Chinese and Korean communists during the Chinese Civil War. Throughout 1949 and 1950, the Soviets continued arming North Korea. After

13356-479: The term " Chosŏn War" ( Chinese : 朝鮮戰爭 ; pinyin : Cháoxiǎn Zhànzhēng ) is sometimes used unofficially. The term " Hán (Korean) War" ( Chinese : 韓戰 ; pinyin : Hán Zhàn ) is most used in Taiwan (Republic of China), Hong Kong and Macau . In the US, the war was initially described by President Harry S. Truman as a " police action " as the US never formally declared war on its opponents, and

13482-663: The theatre. In July 1943, the Seafire was used to provide air cover for the Allied invasion of Sicily ; and reprised this role in September 1943 during the subsequent Allied invasion of Italy , being used to maintain continuous air cover of the beachheads , the type being almost entirely responsible for this task. During the latter operation, around half of the taskforce's Seafires were inoperable within four days, primarily due to landing accidents. During 1944, Seafires were used for air cover in support of several aerial bombing missions against

13608-461: The thicker, repositioned frames obstructed visibility during deck landings. In spite of recommendations to change the windscreen back to a standard Spitfire 24 unit, this was never done. Performance tests showed that the Mk.47 was slightly slower than the Mk.46 in maximum and climbing speeds, mainly due to the long supercharger air intake, which was less efficient than the shorter type fitted to earlier Seafires. The first fourteen aircraft were powered by

13734-435: The type. There were concerns over weak undercarriages , which had not been strengthened to naval standards, but performance was acceptable. From 1942 on, further Seafire models were ordered, including the first operationally-viable Seafire F Mk.III variant. This led to widespread use with the FAA. In November 1942, the first Seafire combat occurred during Operation Torch , the Allied landings in North Africa . In July 1943,

13860-557: The war is officially referred to as the Fatherland Liberation War ( Choguk haebang chŏnjaeng ) or the " Chosŏn [Korean] War" ( 조선전쟁 ; Chosŏn chŏnjaeng ). In mainland China, the segment of the war after the intervention of the People's Volunteer Army is commonly and officially known as the "Resisting America and Assisting Korea War" ( Chinese : 抗美援朝战争 ; pinyin : Kàngměi Yuáncháo Zhànzhēng ), although

13986-483: The war was over. The low point of Seafire operations came during Operation Avalanche the invasion of Salerno in September 1943. Of the 106 Seafires available to the British escort carriers on 9 September only 39 were serviceable by the dawn of D-Day plus Two (11 September). Part of this was attributed to the flat, calm conditions present, which meant that there had not been enough headwind in order to adequately slow down

14112-552: The wings This Mark was built in larger numbers than any other Seafire variant; of the 1,220 manufactured Westland built 870 and Cunliffe Owen 350. In 1947 12 Mk.IIIs were stripped of their naval equipment by Supermarine and delivered to the Irish Air Corps . After the Mk.III series, the next Seafire variant to appear was the Seafire F Mk.XV , which was powered by a Griffon VI – single-stage supercharger, rated at 1,850 hp (1,380 kW) at 2,000 ft (610 m) driving

14238-473: The wings had been designed with a fold just outboard of the undercarriage bays; as such, the outer wings would have swivelled and folded backwards to face parallel with the fuselage. On 29 February 1940, the Admiralty requested that the Air Ministry formally sanction the production of 50 folding-wing Spitfires, the first of which was to be delivered in July that year. For various reasons, Winston Churchill , who

14364-521: Was First Lord of the Admiralty , cancelled the order, writing to Lord Beaverbrook : "I regard it as of very great importance that the production of Fulmars should be kept going". At a time of considerable demand for land-based Spitfires, due to the Fall of France and the subsequent Battle of Britain , the diversion of resources to facilitate the development and manufacture of a naval variant would have naturally reduced Spitfire production. To partially cover

14490-597: Was administered by a US–Soviet Union Joint Commission , as agreed at the Moscow Conference , to grant independence after a five-year trusteeship. Waiting five years for independence was unpopular among Koreans, and riots broke out. To contain them, the USAMGIK banned strikes on 8 December and outlawed the PRK Revolutionary Government and People's Committees on 12 December. Following further civilian unrest,

14616-414: Was almost entirely trained and focused on counterinsurgency, rather than conventional warfare. They were equipped and advised by a force of a few hundred American officers, who were successful in helping the ROKA to subdue guerrillas and hold its own against North Korean military (Korean People's Army, KPA) forces along the 38th parallel. Approximately 8,000 South Korean soldiers and police officers died in

14742-587: Was an armed conflict on the Korean Peninsula fought between North Korea (Democratic People's Republic of Korea; DPRK) and South Korea (Republic of Korea; ROK) and their allies. North Korea was supported by the People's Republic of China and the Soviet Union , while South Korea was supported by the United Nations Command (UNC) led by the United States . The conflict was thus the first major proxy war of

14868-464: Was based on the Spitfire Vc . The Vc had several refinements over the Spitfire Vb. Apart from the modifications included in the main batch of Seafire Ibs this version incorporated catapult spools , and a single slinging lug on either side of the fuselage, just behind the engine bulkhead. Three subtypes were produced, the F Mk.IIc and FR Mk.IIc (fighter reconnaissance), powered by a Merlin 46 , and

14994-408: Was little need for it, and due to the risks posed by asymmetric ignition. The IIc model was the first of the Seafires to be deployed operationally in large numbers, Supermarine constructed 262 of this model and a further 110 being built by Westland , who also built 30 Seafire Mk.III (Hybrid) (Mk.IIIs without folding wings). Although developed for aircraft carrier use, this version still lacked

15120-493: Was no US policy dealing with South Korea directly as a national interest, its proximity to Japan increased its importance. Said Kim: "The recognition that the security of Japan required a non-hostile Korea led directly to President Truman's decision to intervene ... The essential point ... is that the American response to the North Korean attack stemmed from considerations of U.S. policy toward Japan." Another consideration

15246-401: Was not included in the strategic Asian Defense Perimeter outlined by United States Secretary of State Dean Acheson . Military strategists were more concerned with the security of Europe against the Soviet Union than that of East Asia . The administration was worried a war in Korea could quickly escalate without American intervention. Diplomat John Foster Dulles stated: "To sit by while Korea

15372-770: Was not the case. Rather, the soldiers were indigenous to China, as part of China's longstanding ethnic Korean community, and were recruited to the PLA in the same way as any other Chinese citizen. According to the first official census in 1949, the population of North Korea numbered 9,620,000, and by mid-1950, North Korean forces numbered between 150,000 and 200,000 troops, organized into 10 infantry divisions, one tank division, and one air force division, with 210 fighter planes and 280 tanks, who captured scheduled objectives and territory, among them Kaesong, Chuncheon , Uijeongbu , and Ongjin. Their forces included 274 T-34-85 tanks, 200 artillery pieces, 110 attack bombers, 150 Yak fighter planes, and 35 reconnaissance aircraft. In addition to

15498-498: Was reduced to a single man over the course of engagements by the ROKA 8th Division . The second was annihilated by a two-battalion hammer-and-anvil maneuver by units of the ROKA 6th Division , resulting in a toll of 584 KPA guerrillas (480 killed, 104 captured) and 69 ROKA troops killed, plus 184 wounded. By the spring of 1950, guerrilla activity had mostly subsided; the border, too, was calm. By 1949, South Korean and US military actions had reduced indigenous communist guerrillas in

15624-693: Was the Soviet reaction if the US intervened. The Truman administration was fearful a Korean war was a diversionary assault that would escalate to a general war in Europe once the US committed in Korea. At the same time, "[t]here was no suggestion from anyone that the United Nations or the United States could back away from [the conflict]". Yugoslavia —a possible Soviet target because of the Tito-Stalin split —was vital to

15750-408: Was the poor deck behaviour of this mark, especially on take-off. At full power the slipstream of the propeller, which swung to the left (as opposed to the Merlin, which swung to the right), often forced the Seafire to swing to starboard, even with the rudder hard over on opposite lock. This sometimes led to a collision with the carrier's island. The undercarriage oleo legs were still the same of those of

15876-490: Was withdrawn from service during the 1950s. In FAA service, the type had been replaced by the Hawker Sea Fury , the last piston engine fighter to be used by the service, along with the first generation of jet-propelled naval fighters, such as the de Havilland Sea Vampire , Supermarine Attacker , and Hawker Sea Hawk . The Admiralty first showed an interest in the idea of a carrier-borne Spitfire in May 1938 when, during
