The J-7 (Chinese code name: J-7, English: Chengdu J-7/F-7 fighter aircraft, NATO code name: Fishbed, translation: fish nest) fighter jet is a type developed by China’s Shenyang Aircraft Factory in the 1960s Single-seat single-engine supersonic jet fighter. The J-7 is a copy of the Soviet MiG-21Ф-13. The aircraft was later transferred to Chengdu Aircraft Manufacturing Plant and Guizhou Aircraft Manufacturing Plant for subsequent improvement, modification and mass production.
The J-7 is the first double-sonic jet fighter developed by China. It is widely equipped with the Chinese Air Force and Naval Air Force. It is mainly used for homeland air defense and to seize front-line air supremacy on the battlefield. It can also perform ground attack missions. It is a typical second-generation fighter. . The technical features of the J-7 are its high-altitude and high-speed characteristics, its lightness, small size and flexibility, low cost, high efficiency, and simple operation and maintenance. The J-7 fighter has been exported to many countries in the world in batches. China is promoting the J-7 fighter, so there are many second-hand J-7s.
Based on the basic model of J-7, J-7 has derived many improved models, including type I, type II, type III, type A, type B, type E, type M, type MG, type PG, type P, type MP , FS type, MF type, etc.
