The Chengdu Jian-7 (; export versions F-7) is a People's Republic of China-built version of the Soviet Mikoyan-Gurevich MiG-21. Though production ceased in 2008 it continues to serve, mostly as an interceptor, in several air forces.
In the 1950s and early 1960s, the Soviet Union shared most of its conventional weapons technology with the People's Republic of China. One of these was the limited cooperation between the two countries in the early stage development of the famous MiG-21 short-range interceptor-fighter aircraft. Powered by a single engine and designed on a simple airframe, these fighters were inexpensive but fast, suiting the strategy of forming large groups of 'people's fighters' to overcome the technological advantages of Western aircraft. However, the Sino-Soviet split ended Chinese early participation in the developmental program of the MiG-21 abruptly, and from July 28 to September 1, 1960, the Soviet Union withdrew its advisers from China, resulting in the project being forced to stop in China.
However, Nikita Khrushchev suddenly wrote to Mao Zedong in February, 1962 to inform Mao that the Soviet Union was ready to transfer MiG-21 technology to China and asked the Chinese to send their representatives to the Soviet Union as soon as possible to discuss the details. The Chinese viewed this as a Soviet gesture to make peace, and were obviously suspicious, but they were extremely quick to take up on the Soviet offer for the aircraft deal. A delegation headed by Colonel General Liu Yalou (刘亚楼), the commander-in-chief of the PLAAF and a Soviet military academy graduate was dispatched to Moscow immediately and the Chinese delegation was even allowed to have three days to visit the production facility of the MiG-21, which was previously off limits to foreigners. The authorization was personally given by Nikita Khrushchev himself, and on March 30, 1962, the deal was signed. However, given the political situation and relationship between the two countries, the Chinese were not optimistic about gaining the technology and thus were prepared for reverse engineering.
Russian sources stated that complete examples of the MiG-21 were sent to China flown by Soviet pilots, and China did receive MiG-21Fs in kits along with parts and technical documents. Just as the Chinese had expected, when the Soviets delivered the kits, parts and documents to Shenyang Aircraft Factory five months after the deal was signed the Chinese discovered that the technical documents provided by the Soviets were incomplete and some of the parts could not be used. China set about to reverse engineer the aircraft for local production, and in doing so, succeeded in solving 249 major problems and came up with eight major technical documents that were not delivered. The effort was largely successful, as the Chinese design showed only minor differences from the original. In March, 1964, Shenyang Aircraft Factory began the first domestic production of the jet fighter, which they successfully achieved the next year. However, the mass production of the aircraft was severely hindered by an unexpected problem—the Cultural Revolution, which resulted in poor initial quality and slow progress, which in turn, resulted in full scale production only coming about in the 1980s, by which time the design was showing its age. However, the fighter is affordable and widely exported as the F-7, often with Western systems incorporated like the ones sold to Pakistan. Based on the expertise gained by this program, China later developed the Shenyang J-8 by utilizing the incomplete technical information of the Soviet Ye-152 developmental jet.
;Nigeria In early 2008, Nigeria procured 12 F-7NI fighters and three FT-7NI trainers to replace her existing stock of MiG-21 aircraft. The first batch of F-7s arrived in December 2009.
;Sudan Sudanese F-7Bs were used in the Sudanese Civil War against ground targets.
;Tanzania Tanzanian Air Force F-7As served in the Uganda–Tanzania War against Uganda and Libya in 1979. Its appearance effectively brought a halt to bombing raids by Libyan Tupolev Tu-22s.
;Zimbabwe During Zimbabwe's involvement in the DRC, six or seven F-7s were deployed to the Lubumbashi IAP and then to a similar installation near Mbuji-Mayi. From there, AFZ F-7s flew dozens of combat air patrols in the following months, attempting in vain to intercept transport aircraft used to bring supplies and troops from Rwanda and Burundi to the Congo. In late October 1998, F-7s of the No.5 Squadron were used in an offensive in east-central Congo. This began with a series of air strikes that first targeted airfields in Gbadolite, Dongo and Gmena, and then rebel and Rwandan communications and depots in the Kisangani area on November 21.
The role of the J-7 in the People's Liberation Army is to provide local air defence and tactical air superiority. Large numbers are to be employed to deter enemy air operations.
;Myanmar F-7Ms were planned to use for interception. But, they are now out of service and stored as reserve aircraft as new superior fighters arrived.
;Iran Although not in any known combat actions, it was in several movies portraying Iraqi MiG-21s during the Iran–Iraq War. One tells the story of an Islamic Republic of Iran Air Force strike on the Iraqi nuclear reactor at Osirak on September 30, 1980. Another "Attack on H3" tells the story of the 810 km-deep raids into the Iraqi heartland against Iraqi Air Force airfields on April 4, 1981, and other movies depicting the air combat in 1981 that resulted in the downing of around 70 Iraqi aircraft. However, unconfirmed reports claimed that during the later stages of the war, these aircraft were used for air-to-ground attacks. On July 24, 2007 an Iranian F-7 crashed in northern eastern Iran. The plane crashed due to technical difficulties.
;Iraq F-7Bs paid for by Egypt arrived too late for the aerial combat in the early part of the Iran–Iraq War, but later participated mainly in air-to-ground sorties.
;Pakistan Pakistan is currently the largest non-Chinese F-7 operator, with ~120 F-7P and ~60 F-7PG. The Pakistan Air Force is to replace its entire fleet of F-7 with the JF-17 multirole fighter, all F-7P are planned to be retired and replaced with JF-17 Thunder aircraft by 2015.
;Sri Lanka Sri Lanka Air Force currently uses three F-7BS and for ground attack missions against the LTTE and three FT-7 trainer. Due to the lack of endurance and payload, SLAF some times uses their F-7s for pilot training purposes.
Early 2008 the air force received six more advanced F-7Gs, these will be primarily used as interceptors. All The F-7G's, F-7BS's and FT-7s are flown by the No 5 Jet Squadron.
Sri Lankan officials reported that on 9 September 2008, three Sri Lankan Air Force F-7s were scrambled after two rebel flown Zlín-143 were detected by ground radar, two were sent to bomb two rebel airstrips at Mullaitivu and Kilinochchi areas, the government claims the third intercepting one ZLin-143 resulting in one LTTE Zlín-143 shot down by the chasing F-7G using air to air missiles while the rebel flown light aircraft was returning to its base at Mullaitivu after a bombing run against Vavuniya base. There is no public evidence for shooting down LTTE flight.

J-7IIH Improved J-7II variant with enhanced ground attack capability. First J-7 model to have a multi-function display, which is located to the upper right corner of the dashboard. J-7IIH is the first J-7 fighter that is capable of using PL-8 air-to-air missile.
J-7III Reverse-engineered copies of MiG-21MF "Fishbed-J," reportedly obtained from Egypt by Chengdu Aircraft Industry Corp. (CAC) with JL-7 fire-control radar (weight was 100 kg, maximum range is 28 km, and MTBF is 70 hours), Liyang WP-13 turbojet engine, new HUD/avionics, and improved fuel capacity. Limited production of 20-30.
J-7E Improved variant of the J-7II, developed in 1987 as a replacement for the J-7II/F-7B. A new double-delta wing, WP-13F turbojet engine, British GEC-Marconi Super Skyranger radar, increased internal fuel capacity, and improved performance. It is 45% more maneuverable than the J/F-7M, while the take-off and landing distance is reduced to 600 meters, in comparison to the 1,000 meter take-off distance and 900 meter landing distance of earlier versions of the J-7. J-7E is the first of the J-7 family to incorporate HOTAS, which has since become standard on the later versions. This version is also the first of J-7 series to be later upgraded with helmet mounted sights (HMS), however, it is reported that the helmet mounted sight is not compatible with radars, and air-to-air missiles must be independently controlled by either HMS or radar, but not both.
J-7FS Technology demonstration aircraft built by CAC, with redesigned under-chin inlet and WP-13IIS engine. First flew in 1998, only two prototypes were built before being replaced by J-7MF.
J-7G an improved variant of the J-7E by CAC, first flew in 2002. Equipped with a new KLJ-6E PD radar, which is reported to be SY-80 radar with SY is short for Shen Ying, meaning Celestial Eagle in Chinese. This radar a Chinese development of the Italian Pointer-2500 ranging radar used for the Q-5M, and the Italian radar itself was a development of Pointer radar, the Italian copy of Israeli Elta EL/M-2001. In comparison to the Italian Grifo series radar on Pakistani F-7s, the SY-80 weighs more at 60 kg, and the range is also shorter, at 30 km. However, the radar does have a feat that the Italian radars do not have: it is fully compatible with helmet-mounted sights (HMS) so that both the radar and HMS can be worked together to control PL-8/9 air-to-air missiles. One 30 mm gun was removed, and a more powerful engine installed.
JJ-7. Dual-seat J-7 trainer and Chinese equivalent of the MiG-21U Mongol-A design. Originally built by Guizhou Aircraft Design Institute and Guizhou Aircraft Company (now Guizhou Aviation Industry Group/GAIC) in 1981.
JL-9 (FTC-2000). Also known as FTC-2000 Mountain Eagle (Shan Ying), new two-seat trainer derived from the JJ-7 series. Built by GAIC in early 2000s as the low-cost solution to JJ-7 trainer replacement.
F-7A Limited export version of the J-7sans suffixe with a WP-7B engine, one 30mm gun, and 2 under-wing pylons. It was exported to Albania and Tanzania. In accordance with Mao Zedong's foreign aid policy at the time, the export version was armed with better equipment than the domestic one.
F-7B Export version of the J-7II with re-wired pylons using the French R550 Magic Air-to-air missiles. Sold to Egypt (a total of 150 F-7Bs and F-7Ms), Iraq, and Sudan from 1982-1983. The Iraqi units were paid by Egypt.
F-7MG Export variant of the J-7MG, with the single piece windshield replacing the 3-piece windshield of the J-7MG. Evolved to F-7BG. Zimbabwe bought at least 12 of these in 2004.
