Chengdu J-7

The Chengdu J-7 is a Chinese fighter aircraft. It is a license-built derivative of the Soviet Mikoyan-Gurevich MiG-21, and thus shares many similarities with that aircraft. The aircraft is armed with infrared homing air-to-air missiles and is mainly designed for short range air-to-air combat. The aircraft is also used for close air support.

Design and development
Background J-7I at the Beijing Military museum In the 1950s and early 1960s, the Soviet Union shared a large proportion of its conventional weapons technology with its neighbor, China. One such example is the MiG-19, which was locally produced by China as the Shenyang J-6 from as early as 1958. During the same decade, the even more capable MiG-21 had been developed by the Soviets; this fighter, being inexpensive but fast, suited the strategy of forming large groups of 'people's fighters' to overcome the technological advantages of Western aircraft. However, the Sino-Soviet split abruptly ended initial cooperation efforts; between 28 July and 1 September 1960, the Soviet Union withdrew its advisers from China, resulting in the J-7 project coming to a halt in China. During February 1962, Soviet Premier Nikita Khrushchev unexpectedly wrote to Mao Zedong to inform him that the Soviet Union was willing to transfer MiG-21 technology to China, and he asked the Chinese to promptly send their representatives to the Soviet Union to discuss arrangements. The Chinese viewed this offer as a Soviet gesture to make peace, and while suspicious, they were nonetheless eager to take up the Soviet offer of an aircraft deal. A delegation headed by General Liu Yalou, the commander-in-chief of the People's Liberation Army Air Force (PLAAF) and himself a Soviet military academy graduate, was dispatched to Moscow immediately; the Chinese delegation was given three days to visit the MiG-21's production facility, which was previously off-limits to foreigners. The visit's authorization was personally given by Nikita Khrushchev, and on 30 March 1962, the technology transfer deal was signed. Establishing production However, given the state of political relations between the two countries, the Chinese were not optimistic about gaining the technology, and allegedly made preparations to reverse engineer the aircraft. During March 1964, domestic production of the J-7 reportedly commenced at the Shenyang Aircraft Factory. However, mass production efforts were severely hindered by the Cultural Revolution, which resulted in poor initial quality and slow progress. Achieving full domestic production had involved not only the local assembly of the aircraft itself, but the production of its various components and systems, including its turbojet powerplant. As a consequence, full-scale production of the J-7 was only truly achieved during the 1980s, by which time the original aircraft design was showing its age. By the 1980s, quantity production of the General Dynamics F-16 Fighting Falcon fighter was well underway in the United States; this relatively-affordable single-engined western fighter was considerably more agile than the J-7, even with the former carrying a greater payload. Further development J-7III in the 1990s In 1987, the J-7E was introduced, having a greatly improved wing, among other improvements. It was roughly 45% more maneuverable, and its takeoff and landing performance was greatly increased. It was also equipped with a helmet mounted sight, as well as being the first MiG-21 variant to be equipped with HOTAS and a multipurpose display. Many of the electronic components were British in origin, such as the gun sight and the multi purpose display. The aircraft is capable of using PL-8/Python 3 missiles with both the helmet mounted sight or the radar fire control, but the two are not connected. The pilot may use only one system at a time. The J-7 only reached its Soviet-designed capabilities in the mid-1980s. Being relatively affordable, it was widely exported as the F-7, often with Western systems incorporated, such as to Pakistan. There are over 20 different export variants of the J-7, some of which are equipped to use European weaponry, such as French R.550 Magic missiles. The Discovery Channel's Wings Over The Red Star series claims that the Chinese intercepted several Soviet MiG-21s en route to North Vietnam (during the Vietnam War), but these aircraft did not perform in a manner consistent with their original specifications, suggesting that the Chinese actually intercepted down-rated aircraft that were intended for export, rather than fully capable production aircraft. For this reason, the Chinese had to re-engineer the intercepted MiG-21 airframes in order to achieve their original capabilities. China later developed the Shenyang J-8 based both on the expertise gained by the program, and by utilizing the incomplete technical information acquired from the Soviet Ye-152 developmental jet. During May 2013, production of the J-7 was permanently terminated, bringing to a close a period of manufacturing stretching almost 50 years. At the China International Aviation & Aerospace Exhibition in 2018, a display showing the J-7 as an unmanned platform was shown. ==Operational history==
Operational history
Chengdu F-7A Chengdu F-7M . Note the underwing PL-2 missiles Africa Namibia During August 2005, Namibia ordered 12 F-7NMs for its air force; Chinese sources reported the delivery in November 2006. The model procured is believed to be a variation of the F-7PG acquired by Pakistan with Grifo MG radar. Nigeria In early 2008, Nigeria procured 12 F-7NI fighters and three FT-7NI trainers to replace its existing inventory of MiG-21 fighters. On September 20, 2018, two Nigerian F-7Ni aircraft crashed into Katamkpehir, Abuja, killing one pilot after a mid-air collision during a rehearsal of an aerial display for the 58th anniversary of Nigeria's independence. Sudan During the lengthy Second Sudanese Civil War, Sudan procured a number of F-7s. In November 1993, it was reported that Iran had allegedly financed Sudan's purchase of around 20 Chinese ground-attack aircraft, having pledged $17 million in financial aid to the Sudanese government and arranged for $300 million in Chinese arms to be delivered to the Sudanese Army. ;Tanzania The Tanzanian Air Force deployed its F-7As during the Uganda–Tanzania War against Uganda and Libya, fought between 1978 and 1979. Forming a major component of Tanzania's combat aircraft, the type facilitated the defeat of the nominally stronger Uganda Army Air Force during the air campaign. ;Zimbabwe Due to their very limited operational capabilities in the absence of ground support from radars, Zimbabwean F-7s were never used in combat operations during the Second Congo War. Their only deployment in the DR Congo took place in January 2001, when four aircraft were to participate in the burial ceremony for the assassinated president, Laurent-Désiré Kabila. During the journey from Zimbabwe to Kinshasa, one of them crashed, with its pilot ejecting safely. Moreover, on the return trip, two aircraft were damaged on landing, although both were repaired and returned to service. Europe Albania The deployment of F-7As near the country's northern border successfully checked Yugoslav incursions into Albanian airspace in 2002. East and Southeast Asia China Throughout the mid-1990s, the PLAAF began to replace its J-7B inventory with the substantially redesigned and improved J-7E variant. The wings of the J-7E have a new "double delta" design offering improved aerodynamics and increased fuel capacity, and the J-7E also features a more powerful engine and improved avionics. The newest version of the J-7, the J-7G, entered service with the PLAAF in 2003. The principal role of the J-7 in Chinese service is to provide local air defense and tactical air superiority. Large numbers are to be employed to deter enemy air operations. In June 2021, four J-7s participated in a combat drill conducted near Taiwan's air defense identification zone. Myanmar During the 1990s, Myanmar reportedly established four squadrons of F-7s, which have been primarily used for air defense duties. Technical difficulties have reportedly plagued the fleet early on, and their ground-attack performance was not deemed sufficient. Middle East Iran During the 1980s, Iran procured a number of F-7s, despite Chinese officials issuing denials of directly supplying military equipment to the country at that time. Despite its use as a frontline fighter, the type has not been involved in any known air to air combat actions. By the 21st century, it was largely relegated to use as a trainer aircraft. The second confirmed strike was on the 21st of March, 2026 where a single J-7 was destroyed by USAF/CENTCOM strikes on Shahid Sadooghi Airport in Yazd Province. Iraq 20 J-7Bs were initially constructed between 1981 and 1982 for delivery to Jordan by the Third Ministry of Machine, with the first flight of these aircraft taking place in May 1982. 60 F-7Ms transferred from Jordan in a similar way to Iraq in 1985. Iraqi F-7Bs were never officially used in combat used in combat, but only as advanced trainers. In 1988, Jordan also acquired JJ-7 trainers and delivered them to Iraq. By 1999, only about 32 to 34 were operational, with a lack of parts and support, and were mainly used as weapons training platforms. They were withdrawn from service after the 2003 Invasion of Iraq and subsequent dissolution of the old Iraqi forces. South Asia twin-seater FT-7BGI inflight with F-7BGI's Bangladesh The Bangladeshi Air Force currently operates FT-7MB Airguards, and F-7BG and F-7BGI interceptors. That same year, Grumman and China initiated a new design study in another attempt to redesign the F-7 but that effort was also abandoned when the U.S. placed sanctions on China in response to the 1989 Tiananmen Square protests. In 1991, a third initiative involving the F-7 was launched; originally known as the Fighter China project, it led to the creation of the JF-17 Thunder multirole fighter. The aircraft satisfied a requirement issued by the Pakistani Air Force for an affordable and modern combat aircraft, and the country is in the process of replacing its entire F-7 fleet with JF-17s. Sri Lanka In 1991, the Sri Lanka Air Force (SLAF) was looking for a jet attack aircraft to provide fast close air support to its army. With western countries refusing to sell attack aircraft, the Government of Sri Lanka approached China for the purchase of several Nanchang Q-5s, which had the range and payload capacity needed by the SLAF, and was already used by Pakistan and Bangladesh. Due to pressure from the west, China agreed to sell a small number of F-7BS fighters which allowed the SLAF to restore its capabilities that were lost a decade back. Due to the type's comparative lack of endurance and payload, the SLAF has periodically used its F-7s for pilot training purposes. Early in 2008, the air force received six more advanced F-7Gs, to use primarily as interceptors. All of the F-7Gs, F-7BS' and FT-7s are flown by the No 5 Jet Squadron. ==Variants==
