China was receiving aircraft and technical help from the USSR. When Egypt and China
seemed to be looking to the US for assistance, relations with the USSR ended. To keep
aircraft development going in China, Egypt sent a Mig-21MF in return for a Romeo Class
SSK sub. China reverse engineered the Mig-21MF and developed the J-7C/D. Externally
the J-7D was almost identical but had some improved avionics and weapons controls,
many J-7Ds were just upgraded J-7Cs. This J-7D originally was an operational night
fighter under the Beijing MR (Military Region) at Huairen Air Field.
Work on the Chengdu J-7 111 began in 1981 with the first flight taking place in 1984 but
it wasn’t until 1992 that the PLAAF began to be equipped with them. The delay was
caused by the problems the development of the WP-13 engine and its certification. The
Chinese Chengdu J-7 III and the Mig-27MF have an almost identical physical
appearance making the shape of the parachute brake covers one of only a few visible
differences. The Chengdu J-7 III also has blown flaps. There were over 2,450
J-7 variants manufactured.
