The J-7 is a single-seat, single-engine supersonic jet fighter developed by China from 1961 to 1966, based on the Soviet MiG-21F-13. It was primarily designed for territorial air defense and frontline air superiority, with ground attack capabilities for close air support. Manufactured by the Shenyang Aircraft Corporation (later transferred to Chengdu Aircraft Corporation and Guizhou Aircraft Corporation), the J-7 made its maiden flight in 1966 and subsequently entered mass production. It became the backbone of the Peoples Liberation Army Air Force and Naval Air Force, safeguarding the skies of China for over six decades. The J-7 served as a crucial transitional aircraft model for Chinese aviation industry, marking the shift from imitation to independent research and development. It accumulated valuable experience for the development of subsequent Chinese fighter jets and holds a significant place in the history of Chinese aviation.

J-7II
In 1968, the Chengdu Aircraft Corporation of the Chinese Aviation Industry Corporation began to modify the J-7 fighter jet, and in 1975, the J-7I fighter jet was adopted, which featured an improved air intake and dual 30mm cannons. In 1979, the J-7II, equipped with a new ejection seat, a WP-7B turbojet engine, and increased internal fuel, was finalized and put into mass production.

J-7IIIA（J-7D）
In 1978, referring to the Soviet MiG-21MF all-weather fighter, China began developing the J-7III (also known as J-7C), which was equipped with search and fire-control radar, enabling it to operate in all weather conditions. The aircraft made its maiden flight in 1984. In 1995, the J-7IIIA (also known as J-7D), featuring an upgraded WP-13F1 engine with increased thrust and improved avionics, was put into production. However, by the time the J-7III/IIIA was finalized, its performance was already considered outdated, and only 50 airframes were manufactured.

J-7E
In 1986, the Chengdu Aircraft Corporation of the Chinese Aviation Industry Corporation collaborated with Northwestern Polytechnical University to upgrade the J-7II fighter. The aircraft was redesigned with a double-delta wing configuration paired with leading-edge manoeuvring flaps, significantly enhancing its subsonic and transonic manoeuvrability at medium and low altitudes. The aircraft was also equipped with the WP-13F1 engine and advanced avionics. This upgraded model was finalized in 1993 as the J-7E, with a total of 260 airframes produced.
