Because the blackhawks jerseys is not implemented

(formerly known as J -8 Ⅱ type): by the Shenyang Aircraft Corporation, Shenyang Aircraft Design Institute (601) in high-altitude high-speed fighter F -8 developed on the basis of high altitude all-weather fighter. 1964 by the Shenyang Aircraft Design Institute (601) and was jointly  insanity workout by the Shenyang Aircraft Factory single medium-sized all-weather single-seat high-altitude high-speed fighters, mainly in the Soviet 1B supersonic bomber for the war objects, 1980, due to technical performance has lagged behind, and the air force plans to adjust, F -9 high altitude high-speed fighter project was officially stopped development, research into the technical achievements.
Shenyang Aircraft Factory and 601 where the late 60's lightweight fighter program, to be with the Nanchang Aircraft Factory J-type light -12 F -6 light fighter competition, the successor program. Because the  blackhawks jerseys is not implemented, only remain in the program phase, dismount in 1970. 60 end of the decade, developed by the Nanchang Aircraft Manufacturing Factory is responsible for needs of the people's war, the Air Force's short-range to meet the ups and downs, good mobility, low-altitude outstanding performance, use and maintenance simple single-seat single- daytime light supersonic fighter made. mac brushes  December 26, 1970 maiden flight a success. Nanchang Aircraft Factory in October 1973 after the J - north face denali  aircraft made 10 major improvements, the new and improved prototype in July 1, 1975 maiden flight in February 1978, the development of new aircraft models in the clean-up and adjustment equipment system, the Air Force made aircraft performance is not ideal, CMC Development Group decided to conventional equipment not included in the equipment system of the F -12 to stop development.
