The Xian H-8 bomber ({{zh|c=轰-8|p=Hōng-8}}) was a Chinese military aircraft and a possible successor to the aging twin-engined H-6 jet bomber[1]. It is referred to as Xian H-7 in some sources[2]. The proposed designs were reported to be an enlarged H-6 with four or six underwing engines, but the project was canceled in 1971 in early development stage.[3] DevelopmentOn 23 March 1970 the No.603 Research Institute was tasked with developing a strategic bomber to be designated H-8, to reduce costs and development time the Xian H-6 airframe was used as a baseline. The first working sample was expected to be completed in 1973, and production was expected to be as early as in 1974.[1] However, the development of the H-8 paced slowly and came to a halt as major development resource was transferred to Shanghai Y-10. In September 1971, the H-8 project was canceled, whilst the H-6I was continued on as a substitute.[1] Variants
