Chengdu J-7

The Chengdu J-7 (Chinese: 歼-7; pinyin: Jiān-7; third generation export version J-7; NATO reporting name: Fishcan) 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.

On 30 March 1962, the Soviet Union and China signed a technology transference arrangement on the MiG-21. Allegedly, while various kits, components, completed aircraft and associated documents were delivered to the Shenyang Aircraft Factory, the design documentation was incomplete, and Chinese designers made efforts to reverse engineer the aircraft. While the two aircraft are greatly similar, areas of difference include the hydraulic systems and internal fuel arrangements. During March 1964, domestic production of the J-7 reportedly commenced at the Shenyang Aircraft Factory, but due to various factors including the Cultural Revolution, mass production was only truly achieved during the 1980s. Numerous models of the J-7 were developed, featuring improvements in areas such as the armament, avionics, and wing design.
