Guys, according to Gordon & Komissarov: "Chinese Aircraft. China's aviation industry since 1951" (2008) the Shenyang J-8 was a long-range interceptor and the prototype first flew on 5th July 1969. The J-8 I (or J-8A) all-weather interceptor was a significant upgrade on the former, the first prototype was destroyed (25th June 1980) & the 2nd flew on 24th April 1981. The Shenyang JH-8 was a fighter-bomber project initiated ca 1975 and intended to replace the Nanchang Q-5. Shenyang proposed the 'JH-8' (Jiangjiji Hongzhaji meaning fighter bomber), based on the J-8 but with a significantly different airframe. A 3-view in the western press showed an aircraft very similar to the Sukhoi T-58Sh strike aircraft project. The project was cancelled in 1978, but served as the basis for the J-8 II fighter which first flew on 12th June 1984. :-[
