199-824: The North American F-82 Twin Mustang is the last American piston-engined fighter ordered into production by the United States Air Force . Based on the North American P-51 Mustang , the F-82 was originally designed as a long-range escort fighter for the Boeing B-29 Superfortress in World War II . The war ended well before the first production units were operational. In the postwar era, Strategic Air Command used
398-462: A twin-fuselage design, parallel to the experimental German Messerschmitt Bf 109Z "Zwilling." Although based on the lightweight experimental XP-51F, which would later become the P-51H Mustang, it was actually a new design. North American Design Chief Edgar Schmued incorporated two P-51H Mustang fuselages lengthened by the addition of a 57 in (1,400 mm) fuselage plug located behind
597-677: A "systemic problem" in the USAF's management of the nuclear mission. Rolls-Royce Merlin The Rolls-Royce Merlin is a British liquid-cooled V-12 piston aero engine of 27-litre (1,650 cu in) capacity . Rolls-Royce designed the engine and first ran it in 1933 as a private venture. Initially known as the PV-12 , it was later called Merlin following the company convention of naming its four-stroke piston aero engines after birds of prey . The engine benefitted from
796-479: A "universal" propeller shaft, allowing either de Havilland or Rotol manufactured propellers to be used. The first major version to incorporate changes brought about through experience in operational service was the XX, which was designed to run on 100- octane fuel. This fuel allowed higher manifold pressures , which were achieved by increasing the boost from the centrifugal supercharger . The Merlin XX also utilised
995-535: A 40 mm (1.6 in) cannon was considered, but was never built. The outer wings were reinforced to allow the addition of hard points for carrying additional fuel or 1,000 lb (450 kg) of ordnance. The two vertical tails were also from the XP-51F, but incorporated large dorsal fillets for added stability in case of an engine failure. The aircraft had conventional landing gear with both wheels retracting into bays under each fuselage center section. The XP-82
1194-940: A Merlin X with a two-speed supercharger in high gear generated 1,150 hp (860 kW) at 15,400 feet (4,700 m) and 1,160 hp (870 kW) at 16,730 feet (5,100 m). From late 1939, 100-octane fuel became available from the U.S., West Indies , Persia , and, in smaller quantities, domestically, consequently, "... in the first half of 1940 the RAF transferred all Hurricane and Spitfire squadrons to 100 octane fuel." Small modifications were made to Merlin II and III series engines, allowing an increased (emergency) boost pressure of +12 pounds per square inch (183 kPa; 1.85 atm). At this power setting these engines were able to produce 1,310 hp (980 kW) at 9,000 ft (2,700 m) while running at 3,000 revolutions per minute. Increased boost could be used indefinitely as there
1393-581: A North Korean Yak-11 downed over Gimpo Airfield by the USAF 68th Fighter Squadron . Initially intended as a very long-range (VLR) escort fighter , the F-82 was designed to escort Boeing B-29 Superfortress bombers on missions exceeding 2,000 mi (3,200 km) from the Solomon Islands or Philippines to Tokyo, missions beyond the range of the Lockheed P-38 Lightning and conventional P-51 Mustangs. Such missions were part of

Tactical Level Command and Control is where individual battles and engagements are fought. The tactical level of war deals with how forces are employed, and the specifics of how engagements are conducted and targets attacked. The goal of tactical level C2
1791-621: A build-up of lead in the combustion chambers, causing excessive fouling of the spark plugs . Better results were achieved by adding 2.5% mono methyl aniline (M.M.A.) to 100-octane fuel. The new fuel allowed the five-minute boost rating of the Merlin 66 to be raised to +25 pounds per square inch (272 kPa; 2.7 atm). With this boost rating the Merlin 66 generated 2,000 hp (1,500 kW) at sea level and 1,860 hp (1,390 kW) at 10,500 ft (3,200 m). Starting in March 1944,
1990-503: A center wing mounted pod housing an array of recon cameras, and was assigned to the 3200th Photo Test Squadron, being designated, unofficially, the RF-82B. On 27 February 1947, P-82B, named Betty Jo and flown by Colonel Robert E. Thacker , made history when it flew nonstop from Hawaii to New York without refueling, a distance of 5,051 mi (8,129 km) in 14 hr 32 min. It averaged 347.5 mph (559.2 km/h). This flight tested

The slower F-82s had a longer range than the F-94s, and the Twin Mustangs constantly patrolled over many Alaskan villages and towns. Periodically, the F-82s were used for long-range visual reconnaissance near several known rough airstrips on the Chukchi Peninsula that the Soviets had used during World War II as landing fields for lend-lease aircraft and checking for any activity. In addition, flights around

On 30 June, FEAF requested HQ USAF for an additional 21 F-82 aircraft, which was denied. In addition, the projected level of support which could be provided at the level of combat usage FEAF was experiencing was no more than 60 days due to a shortage of parts. The fact was that, when F-82 production ended in April 1948, no provision had been made for an adequate supply of spare parts, as
3184-894: A force multiplier. It allows air assets to more rapidly reach any trouble spot around the world with less dependence on forward staging bases or overflight/landing clearances. Air refueling significantly expands the options available to a commander by increasing the range, payload, persistence, and flexibility of receiver aircraft. Aeromedical evacuation is "the movement of patients under medical supervision to and between medical treatment facilities by air transportation" (JP 1-02). JP 4-02, Health Service Support, further defines it as "the fixed wing movement of regulated casualties to and between medical treatment facilities, using organic and/or contracted mobility airframes, with aircrew trained explicitly for this mission." Aeromedical evacuation forces can operate as far forward as fixed-wing aircraft are able to conduct airland operations. Global precision attack

On 5 July, the 339th Squadron was pulled out of combat and returned to Johnson AB. Shortly afterwards, the 4th Squadron returned to Okinawa, with the 347th Provisional Group being inactivated and control of the 68th Squadron being turned over to the 8th Fighter Group . The 339th had been in combat

In addition, the licensing costs paid to Rolls-Royce for each V-1650 were being increased by Britain after the war. It therefore negotiated in August 1945 with the Allison Division of the General Motors Corporation for a new version of the Allison V-1710 -100 engine. This forced North American to switch subsequent production P-82C and later models to

On 26 January, the armed reconnaissance missions were discontinued and the F-82s were placed on continuous combat air patrols over Kandong Airfield near Pyongyang and over both of Pyongyang's main airfields, ( K-23, Pyongyang and K-24, Pyongyang East ) to monitor enemy air activity. This
13930-435: The ADC interceptor mission. Available F-61s were war-weary and night fighter F-82C/D models were modified into all-weather interceptors to replace them. The production interceptor versions of the Twin Mustang were designated the F-82F and F-82G; the distinguishing feature between the F and G models was largely the nacelle beneath the center-wing that housed radar equipment (F-82F's AN/APG-28 and F-82G's SCR-720C18). In addition,
14129-422: The Air Force's readiness to carry out the nuclear strike operations mission as well as from specific actions taken to assure allies as a part of extended deterrence. Dissuading others from acquiring or proliferating WMD and delivering them contributes to promoting security and is also an integral part of this mission. Moreover, different deterrence strategies are required to deter various adversaries, whether they are
14328-617: The Alaska Air Defense mission. The Twin Mustang was well-suited for the air defense mission in Alaska due to its long-range flying ability. In March 1949, the squadron was reassigned to Ladd AFB , near Fairbanks , where an additional eight (14 total) arrived. In Alaska, the squadron would patrol over wide areas of Alaska as the Soviets flying from airfields in Siberia would often test the air defenses. Beginning in August 1950,
14527-547: The BEAST, the other portions include defending and protecting their base of operations, forming a structure of leadership, directing search and recovery, and basic self aid buddy care. During this event, the Military Training Instructors (MTI) act as mentors and opposing forces in a deployment exercise. In November 2022, the USAF announced that it will discontinue BEAST and replace it with another deployment training program called PACER FORGE. In 2007,
14726-518: The Bentley marque and the factory. Today it is known as Bentley Crewe. Hives further recommended that a factory be built near Glasgow to take advantage of the abundant local work force and the supply of steel and forgings from Scottish manufacturers. In September 1939, the Air Ministry allocated £4,500,000 for a new Shadow factory. This government -funded and -operated factory was built at Hillington starting in June 1939 with workers moving into
14925-915: The Continental United States, the Caribbean Air Command 319th FIS at France Field in the Panama Canal Zone received 15 F-82Fs in December 1948 to replace Black Widows for defending the Panama Canal but remained there only briefly before being reassigned to McChord AFB in May 1949. The Twin Mustang was replaced in ADC service during 1950–1951 by the Lockheed F-94 Starfire , the last being with
15124-459: The F-82 for escorting B-26 Invaders deep into North Korea and for searching out ground targets along the Han River . Making do with what they had was the order of the day, and maintenance crews were cannibalizing everything in sight in order to keep the maximum number of F-82s airborne. During the period 26–30 June, the 68th squadron flew 35 combat sorties, averaging five hours per sortie, with
15323-703: The F-82Es were largely surplus, with the last examples being phased out by September. A few were sent to Far East Air Forces for combat in Korea and some were sent to Alaska for bomber escort missions over the Arctic from Ladd AFB until 1953. The majority went to reclamation and were gone by 1952. With the appearance of the Mikoyan-Gurevich MiG-15 over North Korea in late 1950, the B-29, as well as all of
15522-604: The F-82G Twin Mustang was seen as the interim solution. The last operational P-61s were sent by the 68th and 339th Fighter (All Weather) Squadrons to the reclamation yard at Tachikawa Air Base in February 1950, with Twin Mustangs arriving as replacement aircraft. In Far East Air Forces, there were three squadrons operating the Twin Mustang, consisting of 45 aircraft. The 4th Fighter (All Weather) Squadron
15721-421: The Merlin 130/131 versions specifically designed for the de Havilland Hornet . Ultimately, during tests conducted by Rolls-Royce at Derby , an RM.17.SM (the high altitude version of the Merlin 100-Series) achieved 2,640 hp (1,970 kW) at 36 lb boost (103"Hg) on 150-octane fuel with water injection. With the end of the war, work on improving Merlin power output was halted and the development effort
15920-462: The Merlin 60 series gained 300 hp (220 kW) at 30,000 ft (9,100 m) over the Merlin 45 series, at which altitude a Spitfire IX was nearly 70 mph (110 km/h) faster than a Spitfire V. The two-stage Merlin family was extended in 1943 with the Merlin 66, which had its supercharger geared for increased power ratings at low altitudes, and the Merlin 70 series that were designed to deliver increased power at high altitudes. While
16119-476: The Merlin 66-powered Spitfire IXs of two Air Defence of Great Britain (ADGB) squadrons were cleared to use the new fuel for operational trials, and it was put to good use in the summer of 1944 when it enabled Spitfire L.F. Mk. IXs to intercept V-1 flying bombs coming in at low altitudes. 100/150 grade fuel was also used by Mosquito night fighters of the ADGB to intercept V-1s. In early February 1945, Spitfires of
16318-408: The Merlin X. The later Merlin XX incorporated the two-speed drive as well as several improvements that enabled the production rate of Merlins to be increased. The low-ratio gear, which operated from takeoff to an altitude of 10,000 ft (3,000 m), drove the impeller at 21,597 rpm and developed 1,240 hp (920 kW) at that height; while the high gear's (25,148 rpm) power rating
16517-553: The Merlin ran only on 100-octane fuel, and the five-minute combat limitation was raised to +18 pounds per square inch (224 kPa; 2.3 atm). In late 1943 trials were run of a new "100/150" grade (150-octane) fuel, recognised by its bright-green colour and "awful smell". Initial tests were conducted using 6.5 cubic centimetres (0.23 imp fl oz ) of tetraethyllead (T.E.L.) for every one imperial gallon of 100-octane fuel (or 1.43 cc/L or 0.18 U.S. fl oz/U.S. gal), but this mixture resulted in
16716-543: The Merlin was largely superseded by the Rolls-Royce Griffon for military use, with most Merlin variants being designed and built for airliners and military transport aircraft . The Packard V-1650 was a version of the Merlin built in the United States. Production ceased in 1950 after a total of almost 150,000 engines had been delivered. Merlin engines remain in Royal Air Force service today with
16915-521: The Merlin's components itself. Hillingdon required "a great deal of attention from Hives" from when it was producing its first complete engine; it had the highest proportion of unskilled workers in any Rolls-Royce-managed factory”. Engines began to leave the production line in November 1940, and by June 1941 monthly output had reached 200, increasing to more than 400 per month by March 1942. In total 23,675 engines were produced. Worker absenteeism became
17114-425: The Merlin's technical improvements resulted from more efficient superchargers , designed by Stanley Hooker , and the introduction of aviation fuel with increased octane ratings . Numerous detail changes were made internally and externally to the engine to withstand increased power ratings and to incorporate advances in engineering practices. The Merlin consumed an enormous volume of air at full power (equivalent to
17313-797: The Navy , and the newly created Department of the Air Force. Prior to 1947, the responsibility for military aviation was shared between the Army Air Forces and its predecessor organizations (for land-based operations), the Navy (for sea-based operations from aircraft carriers and amphibious aircraft), and the Marine Corps (for close air support of Marine Corps operations). The 1940s proved to be important for military aviation in other ways as well. In 1947, Air Force Captain Chuck Yeager broke
17512-539: The North Korean aircraft. For some reason, the North Korean leader fired while too far away, with his bullets falling short of the F-82s which then pulled up into the clouds and above the overcast, putting them in a position to return fire if the North Koreans followed them. However, they did not, and no further contact was made for the rest of the day. The evacuation at Inchon was successfully carried out with
17711-627: The P-82 pre-production aircraft already manufactured went into storage, with an uncertain future. However, during the 1947 Soviet Aviation Day display at Tushino Airport , a surprise appearance was put in by what looked like three Boeing B-29s, followed by a fourth, passenger version, the Tu-70. The first three were examples of the Tupolev Tu-4 , which was a reverse-engineered B-29 Superfortress, three examples of which were known to have been interned in
17910-435: The P-82's range. The aircraft carried a full internal fuel tank of 576 US gal (2,180 L; 480 imp gal), augmented by four 310 US gal (1,200 L; 260 imp gal) tanks for a total of 1,816 US gal (6,870 L; 1,512 imp gal). Colonel Thacker did not drop three external tanks when their fuel was expended, either because of an oversight, or because they were stuck due to
18109-836: The P-for-pursuit category with F-for-fighter. All P-82s were then re-designated F-82. The F-82E was the first operational model and its initial operational assignment was to the Strategic Air Command 27th Fighter (later Fighter-Escort) Wing at Kearney Air Force Base , Nebraska in March 1948. During World War II, the P-51 Mustang had escorted Boeing B-17 Flying Fortress and Consolidated B-24 Liberator bombers from bases in England and Southern Italy to targets in Nazi-occupied Europe. However,
18308-402: The Peregrine and Vulture were both cancelled in 1943, and by mid-1943 the Merlin was supplemented in service by the larger Griffon . The Griffon incorporated several design improvements and ultimately superseded the Merlin. Initially the new engine was plagued with problems such as failure of the accessory gear trains and coolant jackets. Several different construction methods were tried before
18507-461: The ROMO. The purpose of nuclear deterrence operations (NDO) is to operate, maintain, and secure nuclear forces to achieve an assured capability to deter an adversary from taking action against vital US interests. In the event deterrence fails, the US should be able to appropriately respond with nuclear options. The sub-elements of this function are: Assure/Dissuade/Deter is a mission set derived from
18706-576: The Spitfire used a variation of this exhaust system fitted with forward-facing intake ducts to distribute hot air out to the wing-mounted guns to prevent freezing and stoppages at high altitudes, replacing an earlier system that used heated air from the engine coolant radiator. The latter system had become ineffective due to improvements to the Merlin itself which allowed higher operating altitudes where air temperatures are lower . Ejector exhausts were also fitted to other Merlin-powered aircraft. Central to
18905-566: The Twin Mustangs already built were seen as an interim solution to SAC's fighter escort mission for its strategic bomber force and also as an all-weather air defense interceptor. Early attempts to develop jet-powered all-weather fighters ran into a series of delays. The Curtiss-Wright XF-87 Blackhawk was ordered in December 1945, but it ran into development difficulties and the project was abandoned in October 1948. The Northrop P-89 Scorpion had greater promise, but it too had teething troubles and
19104-444: The U.S. became available, the engine was adapted to use a conventional liquid-cooling system. The Hart was subsequently delivered to Rolls-Royce where, as a Merlin testbed , it completed over 100 hours of flying with the Merlin C and E engines. In 1935, the Air Ministry issued a specification, F10/35 , for new fighter aircraft with a minimum airspeed of 310 mph (500 km/h ). Fortunately, two designs had been developed:
19303-543: The US determines national or multinational security objectives and guidance, and develops and uses national resources to accomplish these objectives. These national objectives in turn provide the direction for developing overall military objectives, which are used to develop the objectives and strategy for each theater. At the operational level command and control, campaigns and major operations are planned, conducted, sustained, and assessed to accomplish strategic goals within theaters or areas of operations. These activities imply
19502-514: The USAF dwarfs all other U.S. and allied air components, it often provides support for allied forces in conflicts to which the United States is otherwise not involved, such as the 2013 French campaign in Mali . The USAF has also taken part in numerous humanitarian operations. Some of the more major ones include the following: The culture of the United States Air Force is primarily driven by pilots, at first those piloting bombers (driven originally by
19701-464: The USAF established the nuclear-focused Air Force Global Strike Command on 24 October 2008, which later assumed control of all USAF bomber aircraft. On 26 June 2009, the USAF released a force structure plan that cut fighter aircraft and shifted resources to better support nuclear, irregular and information warfare. On 23 July 2009, The USAF released their Unmanned Aerial System (UAS) Flight Plan, detailing Air Force UAS plans through 2047. One third of
19900-509: The USAF undertook a Reduction-in-Force (RIF). Because of budget constraints, the USAF planned to reduce the service's size from 360,000 active duty personnel to 316,000. The size of the active duty force in 2007 was roughly 64% of that of what the USAF was at the end of the first Gulf War in 1991. However, the reduction was ended at approximately 330,000 personnel in 2008 in order to meet the demand signal of combatant commanders and associated mission requirements. These same constraints have seen
20099-577: The United States Air Force provides air support for land and naval forces and aids in the recovery of troops in the field. As of 2020 , the service operates approximately 5,500 military aircraft and approximately 400 ICBMs . The world's largest air force, it has a $ 179.7 billion budget and is the second largest service branch of the U.S. Armed Forces, with 321,848 active duty airmen , 147,879 civilian personnel, 68,927 reserve airmen, 105,104 Air National Guard airmen, and approximately 65,000 Civil Air Patrol auxiliarists . According to
20298-462: The United States Armed Forces and the fourth in order of precedence . The United States Air Force articulates its core missions as air supremacy , global integrated intelligence, surveillance and reconnaissance , rapid global mobility , global strike , and command and control . The United States Air Force is a military service branch organized within the Department of the Air Force , one of
20497-526: The ability to fulfill their primary mission. Rapid Global Mobility is essential to virtually every military operation, allowing forces to reach foreign or domestic destinations quickly, thus seizing the initiative through speed and surprise. Airlift is "operations to transport and deliver forces and materiel through the air in support of strategic, operational, or tactical objectives" (Annex 3–17, Air Mobility Operations). The rapid and flexible options afforded by airlift allow military forces and national leaders
20696-407: The ability to integrate, evaluate, and interpret information from available sources to create a finished intelligence product for presentation or dissemination to enable increased situational awareness. Dissemination and integration is "the delivery of intelligence to users in a suitable form and the application of the intelligence to appropriate missions, tasks, and functions" (JP 2-01). It provides
20895-425: The ability to present information and intelligence products across the ROMO enabling understanding of the operational environment to military and national decision-makers. Rapid global mobility is the timely deployment, employment, sustainment, augmentation, and redeployment of military forces and capabilities across the ROMO. It provides joint military forces the capability to move from place to place while retaining
21094-455: The ability to respond and operate in a variety of situations and time frames. The global reach capability of airlift provides the ability to apply US power worldwide by delivering forces to crisis locations. It serves as a US presence that demonstrates resolve and compassion in humanitarian crisis. Air refueling is "the refueling of an aircraft in flight by another aircraft" (JP 1-02). Air refueling extends presence, increases range, and serves as
21293-559: The aircraft as a long-range escort fighter. Radar-equipped F-82s were used extensively by the Air Defense Command as replacements for the Northrop P-61 Black Widow as all-weather day/night interceptors. During the Korean War , Japan-based F-82s were among the first USAF aircraft to operate over Korea. The first three North Korean aircraft destroyed by U.S. forces were shot down by F-82s, the first being
21492-525: The aircraft from either position, alternating control on long flights, while later night fighter versions kept the cockpit on the left side only, placing the radar operator in the right position. Although some P-82B airframes were completed before the end of World War II, most remained at the North American factory in California waiting for engines until 1946. As a result, none saw service during
21691-465: The aircraft pulled up for the last time, the mortar positions were silent and ground forces later showed over 300 enemy dead. Beginning in October 1950, F-82s would start flying weather reconnaissance pre-dawn missions over North Korea. At the same time, the squadron would also be responsible for keeping at least three aircraft on alert on airfields in the Seoul area ( K-13 (Suwon) and K-14 (Kimpo)) during
21890-491: The aircraft was not expected to remain in operational service once jet-powered aircraft were available. Further, the Air Force simply did not have that many F-82s in the first place (182 total operational aircraft), and did not want to weaken the F-82 units committed to the Pacific Northwest or Atlantic coast, or to draw from the fourteen F-82Hs in Alaska. This was a heavy blow to FEAF planners, as they wanted to use
22089-552: The aircraft's performance seriously. Additionally the unit could be jettisoned in an emergency, or for belly landings and was sometimes even lost during high-G maneuvers. F-82F models were designated for ADC units in the United States, while the F-82G models were deployed to Far East Air Forces for air defense of Japan and Okinawa . F-82s were not deployed to Europe. The first F-82Fs began reaching ADC squadrons in September 1948. By
22288-477: The altitude performance of the Merlin engine necessitated the employment of a two-stage supercharger. As the Merlin evolved so too did the supercharger; the latter fitting into three broad categories: The Merlin supercharger was originally designed to allow the engine to generate maximum power at an altitude of about 16,000 ft (4,900 m). In 1938 Stanley Hooker, an Oxford graduate in applied mathematics, explained "... I soon became very familiar with
22487-478: The basic design of the Merlin was set. Early production Merlins were unreliable: common problems were cylinder head cracking, coolant leaks, and excessive wear to the camshafts and crankshaft main bearings . The prototype, developmental, and early production engine types were the: The Merlin II and III series were the first main production versions of the engine. The Merlin III was the first version to incorporate
22686-430: The beginning of modern aerial warfare and set the stage for the development of the United States Air Force. The U.S. War Department created the first antecedent of the U.S. Air Force, as a part of the U.S. Army, on 1 August 1907, which through a succession of changes of organization, titles, and missions advanced toward eventual independence 40 years later. In World War II , almost 68,000 U.S. airmen died helping to win
22885-519: The bombers it was designed to protect. The first production F-82Es reached the 27th in early 1948, and almost immediately the group was deployed to McChord AFB , Washington , in June, where its squadrons stood on alert on a secondary air defense mission due to heightened tensions over the Berlin Airlift . It was also believed that the 27th would launch an escort mission, presumably to the Soviet Union, if conflict broke out in Europe. From McChord,
23084-436: The case when the aircraft refused to become airborne during its first flight attempt. After a month of work, North American engineers finally discovered that rotating the propellers to meet in the center on their upward turn created sufficient drag to cancel out all lift from the center wing section, one quarter of the aircraft's total wing surface area. The engines and propellers were then exchanged, with their rotation meeting on
23283-420: The clouds using radar and broke out at 2,000 ft (610 m), heading for Kimpo Airfield near Seoul . The pilots observed huge convoys of North Korean trucks and other vehicles, including 58 tanks, which had crossed into South Korea. The crews flew back through the clouds to Itazuke Air Base, where they were debriefed by a U.S. Army colonel from General Douglas MacArthur 's staff. This reconnaissance flight
23482-492: The cockpit where additional fuel tanks and equipment could be installed. These were mounted to a newly designed center wing section containing the same six .50 caliber (12.7mm) M3 Browning machine guns as a single-engine Mustang, but with more concentrated fire. The first XP-82 prototype was equipped with a removable centerline gun pod housing eight additional .50 caliber M2 Brownings, but this did not feature on production aircraft. An even more powerful centerline gun pod containing
23681-463: The command. With the outbreak of the Korean War in June 1950, the F-82 was pressed into combat duty. On 25 June 1950, 68th Fighter Squadron F-82 aircrews on alert at Itazuke Air Base were told that North Korea had crossed the 38th Parallel . They were ordered to fly to the area and report any activity on the main roads and railroads. They arrived to find overcast conditions, with cloud tops at 8,000 ft (2,400 m). The Twin Mustangs flew through
23880-470: The company convention of naming its piston aero engines after birds of prey, Rolls-Royce named the engine the Merlin after a small, Northern Hemisphere falcon ( Falco columbarius ). Two more Rolls-Royce engines developed just prior to the war were added to the company's range. The 885 hp (660 kW) Rolls-Royce Peregrine was an updated, supercharged development of their V-12 Kestrel design, while
24079-488: The construction of the Merlin supercharger and carburettor ... Since the supercharger was at the rear of the engine it had come in for pretty severe design treatment, and the air intake duct to the impeller looked very squashed ..." Tests conducted by Hooker showed the original intake design was inefficient, limiting the performance of the supercharger. Hooker subsequently designed a new air intake duct with improved flow characteristics, which increased maximum power at
24278-483: The design of the two-stage supercharger forged ahead, Rolls-Royce also continued to develop the single-stage supercharger, resulting in 1942 in the development of a smaller "cropped" impeller for the Merlin 45M and 55M; both of these engines developed greater power at low altitudes. In squadron service the LF.V variant of the Spitfire fitted with these engines became known as the "clipped, clapped, and cropped Spitty" to indicate
24477-556: The downward turn, and the problem was fully solved. The first XP-82 prototype ( 44-83886 ) was completed on 25 May 1945, and made the type's first successful flight on 26 June 1945. This aircraft was accepted by the Army Air Forces on 30 August 1945, whose officials were so impressed by the aircraft, while still in development, that they ordered the first production P-82Bs in March 1945, fully three months before its first flight. The XP-82 prototypes, and production P-82Bs and P-82Es, retained both fully equipped cockpits so that pilots could fly
24676-401: The end of September, ADC had 29 F-82Fs. By the middle of 1949 the F-82 was replacing Black Widows in service with Air Defense Command along the west coast at Hamilton AFB , California (317th FIS) and McChord AFB , Washington (318th FIS, 319th FIS). East coast defense was the mission of the Twin Mustangs assigned to McGuire AFB , New Jersey (2d FIS, 5th FIS). In addition to the forces in
24875-538: The end of its production run in 1950, 168,176 Merlin engines had been built; over 112,000 in Britain and more than 55,000 under licence in the U.S. The existing Rolls-Royce facilities at Osmaston, Derby were not suitable for mass engine production although the floor space had been increased by some 25% between 1935 and 1939; Hives planned to build the first two or three hundred engines there until engineering teething troubles had been resolved. To fund this expansion,
25074-479: The enemy holds dear in a devastating manner. If a crisis occurs, rapid generation and, if necessary, deployment of nuclear strike capabilities will demonstrate US resolve and may prompt an adversary to alter the course of action deemed threatening to our national interest. Should deterrence fail, the President may authorize a precise, tailored response to terminate the conflict at the lowest possible level and lead to
25273-472: The engine before discharging the exhaust stream on the outboard side of the UPP nacelle. As a result, sound levels were reduced by between 5 and 8 decibels . The modified exhaust also conferred an increase in horsepower over the unmodified system of 38 hp (28 kW), resulting in a 5 knot improvement in true air speed. Still-air range of the aircraft was also improved by around 4 per cent. The modified engine
25472-474: The fighter version. In 1948, the 3200th Proof Test Group at Eglin AFB , Florida, fitted the 4th F-82B Twin Mustang with retractable pylons under the outer wings capable of mounting 10 High-Velocity Air Rockets (HVAR) each, which folded into the wing undersurface when not in use. This installation was not adopted on later models, the standard "tree" being used instead. The 13th aircraft was experimentally fitted with
25671-483: The fire and movement of friendly forces is not required" (Annex 3-03, Counterland Operations). Close Air Support is defined as "air action by fixed- and rotary-winged aircraft against hostile targets that are in close proximity to friendly forces and which require detailed integration of each air mission with the fire and movement of those forces" (JP 1-02). This can be as a pre-planned event or on demand from an alert posture (ground or airborne). It can be conducted across
25870-451: The front lines and the 38th Parallel. Every F-82 which could be made ready for flight was pressed into combat service. Although Fifth Air Force needed every available aircraft to slow down the North Korean invasion force, it was hard to justify the release of all F-82s from their defensive responsibilities for the many key bases in Japan. It was decided to release all F-82s for combat except for
26069-428: The fuel supply line together with a diaphragm fitted in the float chamber, jocularly nicknamed " Miss Shilling's orifice ", after its inventor, went some way towards curing fuel starvation in a dive by containing fuel under negative G; however, at less than maximum power a fuel-rich mixture still resulted. Another improvement was made by moving the fuel outlet from the bottom of the S.U. carburettor to exactly halfway up
26268-449: The geography of the land. Most movements were up and down roads and paths and railroad rights-of-way. The F-82s would fly low along the terrain then pop up and initiate simulated strafing runs against them, causing the troops to take cover by hitting the muddy tundra. On occasions, the Twin Mustangs would also drop tear gas canisters, simulating gas attacks on the units. United States Air Force The United States Air Force ( USAF )
26467-603: The globe to conduct current and future operations. Planning and directing is "the determination of intelligence requirements, development of appropriate intelligence architecture, preparation of a collection plan, and issuance of orders and requests to information collection agencies" (JP 2-01, Joint and National Intelligence Support to Military Operations). These activities enable the synchronization and integration of collection, processing, exploitation, analysis, and dissemination activities/resources to meet information requirements of national and military decision-makers. Collection
26666-484: The great Ford factory at Manchester started production, Merlins came out like shelling peas ...". Some 17,316 people worked at the Trafford Park plant, including 7,260 women and two resident doctors and nurses. Merlin production started to run down in August 1945, and finally ceased on 23 March 1946. Total Merlin production at Trafford Park was 30,428. As the Merlin was considered to be so important to
26865-494: The group flew its Twin Mustangs on weather reconnaissance missions over the northwest Pacific, but problems were encountered with their fuel tanks. Decommissioned F-61 Black Widow external tanks were found at Hamilton AFB , California, which could be modified for the F-82; fitted on the pylons of the Twin Mustang, these solved the problem. With a reduction in tension, the 27th returned to its home base in Nebraska during September. Four F-82s were deployed from McChord to Alaska, where
27064-661: The hours of darkness and bad weather. This would become the main mission for the F-82s for the balance of 1950, as the F-51s, F-80s and F-84s took on most of the combat ground attack missions which the F-82s had been pressed into at the beginning of the war. With the entry of the Chinese Communist forces into the war, the situation on the ground began to deteriorate rapidly. By late December, the 68th had begun flying two-aircraft missions during daylight and single-aircraft missions at night from Kimpo AB. On 7 January, FEAF ordered

It includes detection and warning; chemical, biological, radiological, and nuclear defense; camouflage, concealment, and deception; hardening; reconstitution; dispersion; redundancy; and mobility, counter-measures, and stealth. Airspace control is "a process used to increase operational effectiveness by promoting the safe, efficient, and flexible use of airspace" (JP 1-02). It promotes
27462-441: The interceptor required numerous modifications. The right side cockpit was replaced with a radar operator's position without flight controls. A long radar pod, resembling a sausage and irreverently known as a "long dong", was attached to the underside of the wing center section, below the six .50 cal (12.7mm) machine guns and with its dish in front of the propellers to prevent interference. This unconventional arrangement did not affect
27661-498: The jet age. Its designed role as a long-range fighter escort was eliminated by the end of World War II. With the rapid draw-down of the armed forces after the war, the newly established United States Air Force had little money for new prop-driven aircraft, especially since jets, such as the Messerschmitt Me 262 , had been faster than P-51 Mustangs in the skies of Germany in late 1944. The completed airframes (minus engines) of
27860-487: The jet-powered F-94 Starfire. USAF claimed the Twin Mustangs destroyed 20 enemy aircraft, four in the air and 16 on the ground during the conflict. During the Korean war, 22 F-82s were lost, including 11 in combat missions and 11 non-combat losses. Modified F-82F/Gs for cold weather were designated as F-82H. Six were assigned initially to the 449th F(AW)S at Adak Island in December 1948 to replace their P-61 Black Widows in
28059-478: The last F-82G was sent for cold-weather modification, and then deployed to Alaska. By mid-April 1952, the F-82s in Okinawa were also sent to Japan for modification and were also sent to Alaska. All-weather responsibilities in FEAF were now in the hands of the F-94 and the jet era. F-82G operational losses during the Korean War 1951 was the last full year of F-82 operations in Korea, as they were gradually replaced by
28258-553: The last civilians out. Fearing that the North Korean Air Force might try to shoot down the transport (a C-54 had been destroyed on the ground at Kimpo by North Korean fighters on 25 June), the Air Force requested air cover to protect the aircraft during takeoff. Fortunately, 339th Fighter All Weather Squadron (F(AW)S) with their F-82Gs were based at Yokota AB and the 68th F(AW)S was based at Itazuke AB Japan. With Lieutenant Colonel John F. Sharp in command, 27 F-82Gs of
28457-428: The level maximum speed of the Spitfire by 10 mph (16 km/h) to 360 mph (580 km/h). The first versions of the ejector exhausts featured round outlets, while subsequent versions of the system used "fishtail" style outlets, which marginally increased thrust and reduced exhaust glare for night flying. In September 1937 the Spitfire prototype, K5054 , was fitted with ejector type exhausts. Later marks of
28656-502: The line was rapidly approaching for the F-82 in Korea. By the end of August 1951, there were only eight operational F-82s with the 68th, with its replacement, the Lockheed F-94 Starfire arriving in Japan, taking over missions previously flown by the Twin Mustangs. In March 1952, the Starfire-equipped 319th Fighter-Interceptor Squadron arrived from Moses Lake AFB , Washington and took up residence at K-13. On 28 March 1952,
28855-400: The lower-powered engines. It was found that Allison-powered P-82 models demonstrated a lower top speed and poorer high-altitude performance than the earlier Merlin-powered versions. The earlier P-82B models were designated as trainers, while the "C" and later models were employed as fighters, making the P-82 one of the few aircraft in U.S. military history to be faster in its trainer version than
29054-481: The maximum boost pressure at which the engine could be run using 87-octane fuel was +6 pounds per square inch (141 kPa; 1.44 atm ). However, as early as 1938, at the 16th Paris Air Show , Rolls-Royce displayed two versions of the Merlin rated to use 100-octane fuel. The Merlin R.M.2M was capable of 1,265 hp (943 kW) at 7,870 feet (2,400 m), 1,285 hp (958 kW) at 9,180 feet (2,800 m) and 1,320 hp (980 kW) on take-off; while
29253-710: The mid-2030s. On 22 October 2023, the USAF conducted its first-ever trilateral exercise with the South Korean and Japanese air forces near the Korean Peninsula. On 29 November 2023, a USAF Bell Boeing V-22 Osprey crashed in the Japan island of Yakushima killing 1 airman. In 2024, citing the Supreme Court 's ruling in Loper Bright Enterprises v. Raimondo , the Air Force refused to comply with an EPA order that they develop
29452-578: The newly dedicated Idlewild Airport in New York City soon followed, with the aircraft flying non-stop from Kearney AFB. In March 1949, Kearney AFB was closed and the 27th FEW was reassigned to Bergstrom Air Force Base , Texas . Other long-range missions were flown cross-country, including simulated dogfights with Lockheed F-80 Shooting Stars . The 27th FEW began transitioning to the Republic F-84 Thunderjet in March 1950, and
29651-424: The number of required sub-contracted parts such as crankshafts, camshafts and cylinder liners eventually fell short and the factory was expanded to manufacture these parts "in house". Initially the local authority promised to build 1,000 new houses to accommodate the workforce by the end of 1938, but by February 1939 it had only awarded a contract for 100. Hives was incensed by this complacency and threatened to move
29850-476: The oil leaks that had been a problem with the early Merlin I, II and III series. The process of improvement continued, with later versions running on higher octane ratings, delivering more power. Fundamental design changes were also made to all key components, again increasing the engine's life and reliability. By the end of the war the "little" engine was delivering over 1,600 hp (1,200 kW) in common versions, and as much as 2,030 hp (1,510 kW) in
30049-400: The pilots provided transition training to the 449th Fighter (All Weather) Squadron, which used Twin Mustangs in the air defense mission. They remained in Alaska for about 45 days, returning to rejoin the rest of the group at the beginning of November 1948. In January 1949, Eighth Air Force planned a large celebration at Carswell Air Force Base . All of its assigned units were to participate in
30248-415: The planes that the USAF planned to buy in the future were to be unmanned. According to Air Force Chief Scientist, Greg Zacharias , the USAF anticipates having hypersonic weapons by the 2020s, hypersonic unmanned aerial vehicles (also known as remotely-piloted vehicles, or RPAs) by the 2030s and recoverable hypersonic RPAs aircraft by the 2040s. The USAF intends to deploy a Sixth-generation jet fighter by
30447-605: The planned U.S. invasion of the Japanese home islands , which was forestalled by the surrender of Japan after the atomic bombings of Hiroshima and Nagasaki and the opening of Soviet attacks on Japanese-held territory in Manchuria. In October 1943, the North American Aircraft design team began work on a fighter design that could travel over 2,000 mi (3,200 km) without refueling. It consisted of
30646-546: The potential consequences of an accident or unauthorized act, nuclear weapons and nuclear weapon systems require special consideration and protection against risks and threats inherent in their peacetime and wartime environments. In conjunction with other entities within the Departments of Defense or Energy, the Air Force achieves a high standard of protection through a stringent nuclear surety program. This program applies to materiel, personnel, and procedures that contribute to
30845-598: The premises in October, one month after the outbreak of war. The factory was fully occupied by September 1940. A housing crisis also occurred at Glasgow, where Hives again asked the Air Ministry to step in. With 16,000 employees, the Glasgow factory was one of the largest industrial operations in Scotland. Unlike the Derby and Crewe plants, which relied significantly on external subcontractors , it produced almost all
31044-483: The production of intelligence" (JP 2-01). It provides the ability to transform, extract, and make available collected information suitable for further analysis or action across the ROMO. Analysis and production is "the conversion of processed information into intelligence through the integration, evaluation, analysis, and interpretation of all source data and the preparation of intelligence products in support of known or anticipated user requirements" (JP 2-01). It provides
31243-473: The production of the Rolls-Royce Avon turbojet and others, the factory was closed in 2005. The Ford Motor Company was asked to produce Merlins at Trafford Park , Stretford , near Manchester , and building work on a new factory was started in May 1940 on a 118-acre (48 ha) site. Built with two distinct sections to minimise potential bomb damage, it was completed in May 1941 and bombed in
31442-537: The propeller-driven bombers in the USAF inventory, were rendered obsolete as strategic offensive weapons. The straight-winged F-84Gs were ineffective against the MiG, and it took the swept-wing North American F-86 Sabre to counter them. It would take a new generation of swept-wing jet bombers, able to fly higher and faster, to survive the MiG-15 and subsequent Soviet interceptors. The era of large formations of bombers flying to
31641-402: The prototype high-altitude Vickers Wellington V bomber, Rolls-Royce started experiments on the design of a two-stage supercharger and an engine fitted with this was bench-tested in April 1941, eventually becoming the Merlin 60. The basic design used a modified Vulture supercharger for the first stage while a Merlin 46 supercharger was used for the second. A liquid-cooled intercooler on top of
31840-475: The racing experiences of precursor engines in the 1930s. After several modifications, the first production variants of the PV-12 were completed in 1936. The first operational aircraft to enter service using the Merlin were the Fairey Battle , Hawker Hurricane and Supermarine Spitfire . The Merlin remains most closely associated with the Spitfire and Hurricane, although the majority of the production run
32039-449: The radomes were removed, turning the aircraft into day fighters. In the ground support role, the F-82s could reach any part of the Korean battlefield with a total ordnance load of over 4,000 lb (1,800 kg). Each of the six .50-inch machine guns carried 400 rounds. This firepower was well-used against numerous ground targets. The escort missions flown with the B-26s took F-82s deep into North Korea. Flying with external fuel tanks, it
32238-491: The safe, efficient, and flexible use of airspace, mitigates the risk of fratricide, enhances both offensive and defensive operations, and permits greater agility of air operations as a whole. It both deconflicts and facilitates the integration of joint air operations. Global integrated intelligence, surveillance, and reconnaissance (ISR) is the synchronization and integration of the planning and operation of sensors, assets, and processing, exploitation, dissemination systems across
32437-602: The safety, security, and control of nuclear weapons, thus assuring no nuclear accidents, incidents, loss, or unauthorized or accidental use (a Broken Arrow incident ). The Air Force continues to pursue safe, secure and effective nuclear weapons consistent with operational requirements. Adversaries, allies, and the American people must be highly confident of the Air Force's ability to secure nuclear weapons from accidents, theft, loss, and accidental or unauthorized use. This day-to-day commitment to precise and reliable nuclear operations
32636-473: The same month. At first, the factory had difficulty in attracting suitable labour, and large numbers of women, youths and untrained men had to be taken on. Despite this, the first Merlin engine came off the production line one month later and it was building the engine at a rate of 200 per week by 1943, at which point the joint factories were producing 18,000 Merlins per year. In his autobiography Not much of an Engineer , Sir Stanley Hooker states: "... once
32835-475: The shortened wingspan , the less-than-perfect condition of the used airframes , and the cropped supercharger impeller. The use of carburettors was calculated to give a higher specific power output, due to the lower temperature, hence greater density, of the fuel/air mixture compared to injected systems. Initially Merlins were fitted with float controlled carburettors. However, during the Battle of Britain it
33034-437: The side, which allowed the fuel to flow equally well under negative or positive g. Further improvements were introduced throughout the Merlin range: 1943 saw the introduction of a Bendix-Stromberg pressure carburettor that injected fuel at 5 pounds per square inch (34 kPa ; 0.34 bar ) through a nozzle directly into the supercharger, and was fitted to Merlin 66, 70, 76, 77 and 85 variants. The final development, which
33233-558: The sound barrier in his X-1 rocket-powered aircraft, beginning a new era of aeronautics in America. The predecessor organizations in the Army of today's Air Force are: During the early 2000s, two USAF aircraft procurement projects took longer than expected, the KC-X and F-35 programs. As a result, the USAF was setting new records for average aircraft age. Since 2005, the USAF has placed
33432-428: The start of the Cold War in 1948, led to the establishment of Air Defense Command (ADC) in the United States Air Force . In 1947, the embryonic ADC was not particularly effective. During a number of simulated raids on the United States carried out by Strategic Air Command during the period 1947–1949, defending F-51 Mustangs and F-47 Thunderbolts repeatedly failed to find the incoming bombers, and were seldom in
33631-413: The strategic bomber force, the 27th FEW was to fly these missions in F-82Es. The F-82E had a range of over 1,400 mi (2,300 km), which meant that with external fuel tanks it could fly from London to Moscow, loiter for 30 minutes over the target, and return, the only American fighter which could do so. It also had an operational ceiling of 40,000 ft (12,000 m), where it could stay close to
33830-431: The success of the Merlin was the supercharger. A.C. Lovesey , an engineer who was a key figure in the design of the Merlin, delivered a lecture on the development of the Merlin in 1946; in this extract he explained the importance of the supercharger: The impression still prevails that the static capacity known as the swept volume is the basis of comparison of the possible power output for different types of engine, but this
34029-425: The supercharger casing was used to prevent the compressed air/fuel mixture from becoming too hot. Also considered was an exhaust-driven turbocharger , but although a lower fuel consumption was an advantage, the added weight and the need to add extra ducting for the exhaust flow and waste-gates meant that this option was rejected in favour of the two-stage supercharger. Fitted with the two-stage two-speed supercharger,
34228-501: The three military departments of the Department of Defense . The Air Force through the Department of the Air Force is headed by the civilian Secretary of the Air Force , who reports to the Secretary of Defense and is appointed by the President with Senate confirmation . The highest-ranking military officer in the Air Force is the Chief of Staff of the Air Force , who exercises supervision over Air Force units and serves as one of
34427-408: The two-speed superchargers designed by Rolls-Royce, resulting in increased power at higher altitudes than previous versions. Another improvement, introduced with the Merlin X, was the use of a 70%–30% water-glycol coolant mix rather than the 100% glycol of the earlier versions. This substantially improved engine life and reliability, removed the fire hazard of the flammable ethylene glycol , and reduced
34626-630: The very latest version as used in the de Havilland Hornet over 2,000 horsepower (1,500 kW). One of the most successful aircraft engines of the World War II era, some 50 versions of the Merlin were built by Rolls-Royce in Derby , Crewe and Glasgow , as well as by Ford of Britain at their Trafford Park factory , near Manchester . A de-rated version was also the basis of the Rolls-Royce/Rover Meteor tank engine. Post-war,
34825-403: The volume of a single-decker bus per minute), and with the exhaust gases exiting at 1,300 mph (2,100 km/h) it was realised that useful thrust could be gained simply by angling the gases backwards instead of venting sideways. During tests, 70 pounds-force (310 N ; 32 kgf ) thrust at 300 mph (480 km/h), or roughly 70 hp (52 kW) was obtained, which increased
35024-643: The war effort, negotiations were started to establish an alternative production line outside the UK. Rolls-Royce staff visited North American automobile manufacturers to select one to build the Merlin in the U.S. or Canada. Henry Ford rescinded an initial offer to build the engine in the U.S. in July 1940, and the Packard Motor Car Company was selected to take on the $ 130,000,000 Merlin order (equivalent to $ 2.83 billion in 2023 dollars ). Agreement
35223-417: The war, with only the infantry suffering more casualties. In practice, the U.S. Army Air Forces ( USAAF ) was virtually independent of the Army during World War II, and in virtually every way functioned as an independent service branch, but airmen still pressed for formal independence. The National Security Act of 1947 was signed on 26 July 1947, which established the Department of the Air Force , but it
35422-404: The war. Like most versions of the P-51 Mustang, the first two prototype XP-82s as well as the next 20 P-82B models were powered by British-designed Rolls-Royce Merlin engines, re-engineered for increased durability and mass-production, and built under license by Packard . These provided the fighter with excellent range and performance; however, the Army had always wanted to give the Twin Mustang
35621-488: The whole operation, but timely intervention by the Air Ministry improved the situation. In 1940 a strike took place when women replaced men on capstan lathes , the workers' union insisting this was a skilled labour job; however, the men returned to work after 10 days. Total Merlin production at Crewe was 26,065. The factory was used postwar for the production of Rolls-Royce and Bentley motor cars and military fighting vehicle power plants. In 1998 Volkswagen AG bought
35820-426: Was 1,175 hp (876 kW) at 18,000 ft (5,500 m). These figures were achieved at 2,850 rpm engine speed using +9 pounds per square inch (1.66 atm ) (48") boost. In 1940, after receiving a request in March of that year from the Ministry of Aircraft Production for a high-rated (40,000 ft (12,000 m)) Merlin for use as an alternative engine to the turbocharged Hercules VIII used in
36019-522: Was 32,377. The original factory closed in March 2008, but the company maintains a presence in Derby. To meet the increasing demand for Merlin engines, Rolls-Royce started building work on a new factory at Crewe in May 1938, with engines leaving the factory in 1939. The Crewe factory had convenient road and rail links to their existing facilities at Derby. Production at Crewe was originally planned to use unskilled labour and sub-contractors with which Hives felt there would be no particular difficulty, but
36218-446: Was attached to the 51st Fighter-Interceptor Wing at Naha Air Base , Okinawa, tasked with providing air defense within the Twentieth Air Force's area of responsibility during darkness and inclement weather. The 68th F(AW)S area would cover southern Japan from their base at Itazuke and the 8th Fighter Bomber Wing , with the 339th F(AW)S covering Tokyo and northern Japan from Johnson Air Base . FEAF had about 40 Twin Mustangs assigned to
36417-559: Was concentrated on civil derivatives of the Merlin. Development of what became the "Transport Merlin" (TML) commenced with the Merlin 102 (the first Merlin to complete the new civil type-test requirements) and was aimed at improving reliability and service overhaul periods for airline operators using airliner and transport aircraft such as the Avro Lancastrian , Avro York (Merlin 500-series), Avro Tudor II and IV (Merlin 621), Tudor IVB and V (Merlin 623), TCA Canadair North Star (Merlin 724) and BOAC Argonaut (Merlin 724-IC). By 1951
36616-935: Was designated the "TMO" and the modified exhaust system was supplied as kit that could be installed on existing engines either by the operator or by Rolls-Royce. Power ratings for the civil Merlin 600, 620, and 621-series was 1,160 hp (870 kW) continuous cruising at 23,500 feet (7,200 m), and 1,725 hp (1,286 kW) for take-off. Merlins 622–626 were rated at 1,420 hp (1,060 kW) continuous cruising at 18,700 feet (5,700 m), and 1,760 hp (1,310 kW) for take-off. Engines were available with single-stage, two-speed supercharging (500-series), two-stage, two-speed supercharging (600-series), and with full intercooling, or with half intercooling/charge heating, charge heating being employed for cold area use such as in Canada. Civil Merlin engines in airline service flew 7,818,000 air miles in 1946, 17,455,000 in 1947, and 24,850,000 miles in 1948. From Jane's : Most of
36815-428: Was either dead or badly wounded, remained in the doomed aircraft. Parachuting down to Kimpo Airfield, the North Korean pilot was immediately surrounded by South Korean soldiers. Surprisingly, he pulled out a pistol and began firing at them. The South Korean soldiers returned fire, killing him. Moments later, Lt. Moran shot down an La-7 over the airfield, while a few miles away, Major James W. Little, commanding officer of
37014-400: Was essential as any Chinese aircraft operating out of these bases would be in easy range of the UN front lines. The 68th's efforts claimed 35 trucks destroyed, with damage to many others. As 1951 progressed, the F-82s of the 68th Squadron continued its mission of air defense over Seoul and flying weather reconnaissance flights; however, its combat duties became more and more limited. The end of
37213-409: Was fitted to the 100-series Merlins, was an S.U. injection carburettor that injected fuel into the supercharger using a fuel pump driven as a function of crankshaft speed and engine pressures. At the start of the war, the Merlin I, II and III ran on the then standard 87-octane aviation spirit and could generate just over 1,000 hp (750 kW) from its 27-litre (1,650-cu in) displacement:
37412-402: Was for the four-engined Avro Lancaster heavy bomber. The Merlin continued to benefit from a series of rapidly-applied developments, derived from experiences in use since 1936. These markedly improved the engine's performance and durability. Starting at 1,000 horsepower (750 kW) for the first production models, most late war versions produced just under 1,800 horsepower (1,300 kW), and
37611-462: Was found that if Spitfires or Hurricanes were to pitch nose down into a steep dive, negative g -force ( g ) produced temporary fuel starvation causing the engine to cut-out momentarily. By comparison, the contemporary Bf 109E , which had direct fuel injection , could "bunt" straight into a high-power dive to escape attack. RAF fighter pilots soon learned to avoid this with a "half-roll" of their aircraft before diving in pursuit. A restrictor in
37810-457: Was necessary on many occasions for the Twin Mustangs to drop tanks, owing to the risk of fire or explosion if enemy fire hit one of the empty tanks. On 10 July, F-82s from the 4th and 68th squadrons participated in one of the biggest strikes of the war against ground targets. Joined by B-26s and F-80s, the aircraft hit massive amounts of North Korean road traffic. An estimated 117 trucks, 38 tanks and seven personnel carriers were destroyed, along with
38009-430: Was no mechanical time limit mechanism, but pilots were advised not to use increased boost for more than a maximum of five minutes, and it was considered a "definite overload condition on the engine"; if the pilot resorted to emergency boost he had to report this on landing, when it was noted in the engine log book, while the engineering officer was required to examine the engine and reset the throttle gate. Later versions of
38208-410: Was not expected to enter service until 1952 at the earliest. Due to the lack of a suitable jet-powered replacement, the wartime Northrop P-61 Black Widow night fighter was forced into this role, and in order to fill in the gap until the Scorpion became available, night fighter adaptations of the Twin Mustang were developed and deployed. On 11 June 1948, the newly formed United States Air Force replaced
38407-414: Was not until 18 September 1947, when the first secretary of the Air Force, W. Stuart Symington , was sworn into office that the Air Force was officially formed as an independent service branch. The act created the National Military Establishment (renamed Department of Defense in 1949), which was composed of three subordinate Military Departments, namely the Department of the Army , the Department of
38606-415: Was refining the Merlin. As a result, the Peregrine saw use in only two aircraft: the Westland Whirlwind fighter and one of the Gloster F.9/37 prototypes. The Vulture was fitted to the Avro Manchester bomber, but proved unreliable in service and the planned fighter using it – the Hawker Tornado – was cancelled as a result. With the Merlin itself soon pushing into the 1,500 hp (1,100 kW) range,
38805-435: Was seen as proof of the F-82's capabilities in bad weather. In early 1949, the 27th began carrying out long-range escort profile missions. Flights to Puerto Rico , Mexico, the Bahamas and nonstop to Washington, D.C. were carried out. For President Truman 's 1949 inauguration, the 27th FEW launched 48 aircraft to fly in review, along with several other fighter units, in formation down Pennsylvania Avenue. Another flyover of
39004-427: Was sent to Inchon harbor to evacuate non-military personnel from Seoul, which lay directly in the invasion route. A flight of Twin Mustangs from the 68th F(AW)S was dispatched to the area, arriving at dawn to provide air protection for the evacuation. Two of the F-82s were dispatched to fly over the road from Seoul, while others flew top cover over the Inchon docks. The patrol went without incident until about 1300, when
39203-429: Was that he had repeatedly clashed with Wynne and Moseley over other important non-nuclear related issues to the service. This followed an investigation into two incidents involving mishandling of nuclear weapons : specifically a nuclear weapons incident aboard a B-52 flight between Minot AFB and Barksdale AFB , and an accidental shipment of nuclear weapons components to Taiwan. To put more emphasis on nuclear assets,
39402-449: Was the first officer appointed to that position who did not have a background as a fighter or bomber pilot. The Washington Post reported in 2010 that General Schwartz began to dismantle the rigid class system of the USAF, particularly in the officer corps. In 2014, following morale and testing/cheating scandals in the Air Force's missile launch officer community, Secretary of the Air Force Deborah Lee James admitted that there remained
39601-474: Was to be powered by two Packard-built Rolls-Royce V-1650 Merlin engines. Initially, the left engine was a V-1650-23 with an additional gear in the propeller reduction box to allow the left propeller to turn opposite to the right propeller, which was driven by the more conventional V-1650-25. In this arrangement both propellers would turn upward as they approached the center wing, which in theory would have allowed better single-engine control. This proved not to be
