The Republic F-84 Thunderjet is an American turbojet fighter-bomber aircraft. Originating as a 1944 United States Army Air Forces (USAAF) proposal for a "day fighter," the F-84 first flew in 1946.  The aircraft was not considered fully operational until the 1949 F-84D model and the design matured only with the definitive F-84G introduced in 1951. In 1954, the straight-wing Thunderjet was joined by the swept-wing F-84F Thunderstreak fighter and RF-84F Thunderflash photo reconnaissance aircraft.
 
The Korean War
The Thunderjet had a distinguished record during the Korean War. After the entry of the People's Republic of China into the war in October 1950, the US Fifth Air Force requested that a wing of F-84s be sent to Korea.  While the F-84B and F-84C could not be deployed overseas because their J35 engines had a service life of only 40 hours, the F-84D and F-84E were more suitable, and so the F-84E-equipped 27th Fighter Escort Group was sent to the Far East aboard the aircraft carrier Bataan, which arrived in Japan on 30 November 1950.
 
After maintenance, the F-84s moved to Taegu airfield (known as K-2), flying its first operational missions on 7 December 1950.  The aircraft were initially tasked with escorting the B-29 Superfortress bombers. The first Thunderjet air-to-air victory was scored on 21 January 1951 at the cost of two F-84s. The F-84 was outmatched by the swept-wing Soviet Mikoyan-Gurevich MiG-15, which was both faster and more maneuverable, and the MiG counter-air mission was soon given to the F-86 Sabre.  The F-84 switched to the ground attack role at which it excelled.
 
The number of units operating the F-84 over Korea gradually increased, both by bringing over Air National Guard Groups from the US, and converting F-80 squadrons already in theater.   The F-84 flew a total of 86,408 missions, dropping 55,586 tons (50,427 metric tons) of bombs and 6,129 tons (5,560 metric tons) of napalm, and firing 22,154 rockets.  The USAF claimed F-84s were responsible for 60% of all ground targets destroyed in the war.  Notable F-84 operations included the 1952 attack on the Sui-ho Dam.  During the war, the F-84 became the first USAF fighter to utilize aerial refueling.  
 
In aerial combat, F-84 pilots were credited with eight MiG-15 kills against a Soviet-claimed loss of 64 aircraft. The total losses were 335 F-84D, E and G models. According to the USAF FY1953 statistical digest, during the Korean war, 305 F-84s were lost, including 249 in combat missions and 56 non-combat losses.
 
After 
The F-84 was the first production fighter aircraft to utilize inflight refueling and the first fighter capable of carrying a nuclear weapon, the Mark 7 nuclear bomb.  Modified F-84s were used in several unusual projects, including the FICON and Tom-Tom dockings to the B-29 Superfortress and B-36 bomber motherships, and the experimental XF-84H Thunderscreech turboprop.
 
The F-84F would continue in service with Air National Guard units until 1971, when corrosion forced them to be withdrawn from U.S. service.  The F-84F and RF-84F were both used by several foreign operators including Germany, The Netherlands, Belgium, France, Italy, Greece, Turkey, and Denmark (one squadron of RF-84F that were phased out in 1971).  The F-84F continued to serve in European air forces until the 1980s.
 
The Republic Aviation Corporation was an American aircraft manufacturer based in Farmingdale, New York, on Long Island.  Originally known as the Seversky Aircraft Company, the company was responsible for the design and production of many important military aircraft, including its most famous products: World War II's P-47 Thunderbolt fighter, the F-84 Thunderjet and F-105 Thunderchief jet fighters.
 
Of note, Nick wrote a story about his grandfather - a USAF fighter pilot - and his time in Korea, which included flying this very airframe.  Find the article here.
