Zhi-8 (Z-8) is a medium transport helicopter developed from the French SA 321 Super Frelon, of which 13 examples were sold to the PLA Navy in 1977~78. At least one of these helicopters was disassembled for survey and reverse-engineering. Development of the Chinese copy of the SA 321, designated Z-8, began in 1976 at the Jingdezhen-based Changhe Aircraft Factory (now Changhe Aircraft Industry Group, CAIG). However, the Z-8 development encountered enormous technical difficulties and the project was suspended in 1979 due to financial reasons.
In 1985, Changhe resumed the Z-8 programme with its own funding, and the first prototype successfully flew in December 1985. The Z-8 entered the PLA Navy service in 1989 for trial and evaluation, but the helicopter was not certified for design finalisation until 1994. Only a small number (15~20) have been built. The helicopter was mainly deployed by the PLA Navy for transport role from land-based airfields.
