Description: The MiG-21F is a short-range day fighter-interceptor and the first major production version of the popular MiG-21 series. It is but one of many versions of this aircraft that have served in the air arms of many nations around the world. The E-5 prototype of the MiG-21 was first flown in 1955 and made its first public appearance during the Soviet Aviation Day display at Moscow's Tushino Airport in June 1956. During the Vietnam War, MiG-21s were often used against U.S. aircraft. Between April 26, 165, and January 8, 1973, USAF F-4s and B-52s downed 68 MiG-21s. More than 30 countries of the world-including nations friendly to the U.S. -have flown the MiG-21. At least 15 versions of the MiG-21 have been produced, some outside the Soviet Union. Estimates place the number built at more than 8,000, a production total exceeding that of any other modern jet aircraft. The Soviets licenced the manufacture of the MiG-21F and its engine to China in 1961, and assembly of the first J-7 (Jianjiji-7 Fighter aircraft 7) using Chinese-made components began early 1964. The first flight of the Shenyang-built J-7 came on 17 January 1966, and Chengdu production of the J-7-I began in June 1967. Neither version was produced in large numbers. Subsequent modifications included development of the J-7-II / J-7B which began in 1975 with production approved in September 1979. Development of F-7M and J-7 III started in 1981. The J-7 III is the Chinese equivalent of MiG-21MF. Substantially reworked from the J-7 II, the J-7 III first flight occured on 26 April 1984. Jointly developed by Chengdu and Guizhou (GAIC), the J-7 III entered PLA Air Force and Navy service beginning in 1992, with production continuing thereafter. Other development efforts extended through the F-7M Airguard which received a production go-ahead in December 1984. In 1988 China delivered the first 20 of 60 F-7M Skybolts to Pakistan. As upgrades, Karachi reportedly was leaning to a totally indigenous Chinese aircraft over the Grumman-influenced Sabre II, or F-7P. Development of the "Super 7" upgrade was terminated with the end of American technical assistance following the Tienanmen repression of 1989. The aircraft has mid-mounted delta wings with small square tips. There is one turbojet inside the body. There is a small round air intake in the nose. There is a single exhaust. The fuselage is a long, tubular body with a blunt nose and bubble canopy. There is one belly fin under the rear section. There is a large dorsal spine flush with the canopy. The tail fin swept-back and tapered with a square tip. The flats are mid-mounted on the body, swept-back, and tapered with square tips. The J-7FS modification adds a radar to a reconfigured air intake, while the "Super 7" upgrade would have completely reworked the front end of the aircraft, adding a much larger radar and ventral air inlets, along with various other less pronounced improvements. By 1989 Chinese production was running at a rate of as much as 14 aircraft per month, primarily for export. The J-7 aircraft was the most widely produced Chinese fighter, replacing older J-6 fighters, the Chinese version of the MiG-19. In 1995 it was projected that J-7 production would continue for at least another decade, resulting in a total inventory of nearly 1000 aircraft by 2005, but in fact the PLAAF inventory has remained static since then at about 500 aircraft, suggesting that production has either been suspended or terminated. MiG-21 aircraft acquired by the United States under the Foreign Materiel Acquisition/Exploitation program are designated as the YF-110.
