The Lockheed P-80 Shooting Star was the first operational jet fighter used by the United States Army Air Forces,[2] and saw extensive combat in Korea with the United States Air Force as the F-80. As one of the world's first successful turbojet-powered combat aircraft, it helped usher in the "jet age" in the USAF and other air forces worldwide. One of its claims to fame is in training a new generation of pilots, especially in its closely-related T-33 Shooting Star trainer development.

[edit] Design and development
Concept work began on the XP-80 in 1943 with a design being built around the blueprint dimensions of a British de Havilland H-1 B turbojet, a powerplant to which the design team did not have actual access. Lockheed's team, consisting of 28 engineers, was led by the legendary Clarence L. "Kelly" Johnson. This teaming was an early product of Lockheed's Skunk Works, which would surface again in the next decade to produce a line of high-performance aircraft beginning with the F-104 Starfighter.
The XP-80 was a conventional, all-metal airframe with a slim low wing and tricycle undercarriage (landing gear). The P-80 was the first operational jet fighter to have its engine integrated within the main fuselage, as pioneered by the earlier Gloster E.28/39 demonstrator. Other early jet fighters generally had two engines because of their power and mounted these in external pods for easier maintenance. With the advent of more powerful engines, fuselage mounting was more effective and would be used by nearly all subsequent fighter aircraft.
The first prototype (44-83020), nicknamed Lulu-Belle (and also known as "the Green Hornet" because of its green paint scheme), flew on 8 January 1944 with Lockheed test pilot Tony LeVier at the controls, just 143 days after design work commenced, which was a full 37 days ahead of schedule. Lulu-Belle was powered by a replacement Halford H1 (later Goblin) taken from the prototype de Havilland Vampire jet fighter and shipped to the States after the original flight engine was accidentally destroyed. Following its first flight, Johnson said, "It was a magnificent demonstration, our plane was a success -- such a complete success that it had overcome the temporary advantage the Germans had gained from years of preliminary development on jet planes.".
The second prototype, designated XP-80A, was designed for the larger General Electric I-40 (an improved Rolls-Royce Derwent engine, later produced by Allison as the J33) engine, with two aircraft (44-83021 and 44-83022) built. 44-83021 was nicknamed the "Gray Ghost" after its "pearl gray" paint scheme, while the second XP-80A, left unpainted for comparison of flight characteristics, became known as the "Silver Ghost". Its first test flight was unimpressive, but most of the problems with the design were soon addressed and corrected in the test program. Initial opinions of the I-40 powered P-80A were not positive, with Lockheed chief engineering test pilot Milo Burcham commenting an aircraft that he very much enjoyed (powered by the Halford engine) had now become a "dog." The XP-80As were primarily testbeds for bigger engines and intake duct design, and consequently were larger and 25% heavier than the XP-80.
The P-80 testing program proved very dangerous. Burcham was killed on 20 October 1944 while flying the third YP-80A produced, 44-83025. The "Gray Ghost" was lost on a test flight on 20 March 1945, although pilot Tony LeVier escaped. Newly promoted to chief engineering test pilot to replace Burcham, LeVier bailed out when one of the engine's turbine blades broke, causing structural failure in the airplane's tail. LeVier landed hard and broke his back, but returned to the test program after six months of recovery. Noted ace Major Richard Bong was also killed on an acceptance flight of a production P-80 in the United States on 6 August 1945. Both Burcham and Bong crashed as a result of main fuel pump failure. Burcham's death was the result of a failure to brief him on a newly installed emergency fuel pump backup system, but the investigation of Bong's crash found he had apparently forgotten to switch on the emergency fuel pump that could have prevented the accident. He bailed out when the aircraft rolled inverted but was too close to the ground for his parachute to deploy.
[edit] Navy usage
Several P-80A Shooting Stars[3] were transferred to the United States Navy beginning June 29, 1945, retaining their P-80 designations. At Naval Air Station Patuxent River, one Navy P-80 was modified (with required add-ons, such as a tail hook) and loaded aboard the aircraft carrier Franklin D. Roosevelt at Norfolk, Virginia, on October 31, 1946. The following day the aircraft made four deck-run takeoffs and two catapult launches, with five arrested landings, flown by Marine Major Marion Carl. A second series of trials was held November 11.[4]
The Navy had already begun procuring its own jet aircraft, but the slow pace of delivery was causing retention problems among pilots, particularly those of the Marines who were still flying Corsairs. To increase land-based jet transition training in the late 1940s, 50 F-80Cs were transferred to the Navy from the Air Force in 1949 as jet trainers. Designated TO-1 by the Navy (changed to TV-1 in 1950), 25 were based at Naval Air Station North Island, California, with VF-52, and 16 assigned to the Marine Corps, equipping VMF-311 at Marine Corps Air Station El Toro. These aircraft were eventually sent to reserve units. The success of these aircraft led to the procurement by the Navy of 698 T-33 Shooting Stars (as the TO-2/TV-2) to provide a two-seat aircraft for the training role. Lockheed went on to develop a carrier-capable version, the T2V SeaStar, which went into service in 1957.[5]

[edit] Operational history
The Shooting Star began to enter service in late 1944 with 12 pre-production YP-80A's one of which was destroyed in the accident that killed Burcham. A thirteenth YP-80A was modified to the only F-14 photo reconnaissance model and lost in a December crash), Four were sent to Europe for operational testing (two to England and two to the 1st Fighter Group at Lesina, Italy) but when test pilot Major Frederic Borsodi was killed in a crash caused by an engine fire on 28 January 1945, demonstrating YP-80A 44-83026 at RAF Burtonwood, the YP-80A was temporarily grounded. Because of the delay the Shooting Star saw no combat in World War II.
The initial production order was for 344 P-80As after USAAF acceptance in February 1945. Eighty-three (83) had been delivered by the end of July 1945 and 45 assigned to the 412th Fighter Group (later redesignated the 1st Fighter Group) at Muroc Army Air Field. After the war, production continued, although wartime plans for 5,000 were quickly reduced to 2,000 at a little under $100,000 a copy. A total of 1,714 single-seat F-80A, F-80B, F-80C and RF-80s were manufactured by the end of production in 1950, of which 927 were F-80Cs (including 129 operational F-80As upgraded to F-80C-11-LO standards). However, the two-seat TF-80C, first flown on 22 March 1948, became the basis for the T-33 trainer, of which 6,557 were produced.
The P-80B prototype, modified as a racer and designated XP-80R, was piloted by Colonel Albert Boyd to a world air speed record of 623.73 mph (1004.2 km/h) on 19 June 1947. The P-80C began production in 1948; on 11 June, now part of the United States Air Force, the P-80C was officially redesignated the F-80C.
The USAF Strategic Air Command had F-80 Shooting Stars in service from 1946 through 1948 with the 1st and 56th Fighter Groups. The first P-80s to serve in Europe joined the 55th Fighter Group (later redesignated the 31st FG) at Giebelstadt, Germany, in 1946, remaining eighteen months. When the Soviet Union blockaded Berlin, a squadron of the 56th FG led by Col. David C. Schilling made the first west-to-east Atlantic crossing by single-engined jets in July, flying to Germany for 45 days in Operation Fox Able I.[6] Replaced by the newly F-80-equipped 36th Fighter Group at Furstenfeldbruck, the 56th FG conducted Fox Able II in May 1949. That same year F-80s first equipped the 51st Fighter Group, based in Japan.
The 4th (Langley Air Force Base, Virginia), 81st (Kirtland Air Force Base, New Mexico), and 57th (Elmendorf Air Force Base, Alaska) Fighter Groups all acquired F-80s in 1948, as did interceptor squadrons of the Air Defense Command. The first Air National Guard unit to fly the P-80 was the 196th FS of the California ANG in June 1947.
[edit] Korea
Shooting Stars first saw combat service in the Korean War, employing both the F-80C variant and RF-80 photo-recon variants. The first jet-versus-jet aircraft battle took place on 8 November 1950 in which an F-80 piloted by Lieutenant Russell J. Brown shot down a MiG-15.[7] Despite the initial success, the straight-wing F-80s were inferior in performance to the MiGs and were soon replaced in the air superiority role by the swept-wing F-86 Sabre. When sufficient Sabres were in operation, the Shooting Star was assigned to ground attack missions, advanced flight training duties and air defense in Japan. By the end of hostilities the only F-80s still flying in Korea were photo-recon variants.
Four units of F-80s saw duty in Korea:
- The 8th Fighter-Bomber Wing (35th, 36th, and 80th Fighter-Bomber Squadrons), based at Suwon, was the longest-serving F-80 unit in Korea. It began missions from Japan in June 1950 and continued to fly the Shooting Star until May 1953, when it converted to F-86 Sabres.
- The 49th Fighter-Bomber Group (7th, 8th and 9th Fighter-Bomber Squadrons) deployed to Taegu, Korea, from Japan in September 1950 and continued fighter-bomber missions in the F-80C until spring 1952, when it converted to the F-84 Thunderjet.
- The 51st Fighter-Interceptor Wing (16th and 25th FIS) operated F-80Cs from Kimpo and Japan from September 1950 to November 1951 when it transitioned to F-86s.
- The 35th Fighter-Interceptor Group and two squadrons, the 39th and 40th FIS, went to Pohang, Korea in July 1950, but converted to P-51 Mustang before the end of the year.
One unit of RF-80A saw duty in Korea:
- The 8th Tactical Reconnaissance Squadron, later redesignated 15th TRS, served from 27 June 1950 at Itazuke, Japan, Taegu (K-2) and Kimpo (K-14), Korea, until after the armistice. The squadron also ulilized a few converted RF-80Cs and RF-86s.
Of the 277 F-80s lost in operations (approximately 30% of the existing inventory), 113 were destroyed by ground fire and 14 shot down by enemy aircraft.[1] F-80s are credited by the USAF with destroying 17 aircraft in air-to-air combat and 24 on the ground.[8] Major Charles J. Loring, Jr. was posthumously awarded the Medal of Honor for his actions while flying with the 80th Fighter-Bomber Squadron, 8th Fighter-Bomber Wing on 22 November 1952.

[edit] Derivatives
Lockheed also produced a two-seat trainer variant with a longer fuselage, the T-33, which remained in production until 1959 and was produced under license in Japan and Canada. The trainer was used by more than 20 different countries. A total of 6,557 T-33s were built and some are still flying.
Two TF-80Cs wre modified as prototypes for the F-94 Starfire, an all-weather fighter which was produced in three variants.
