FM-80 (CH-SA-4)

The FM-80 (export designation for HQ-7) is a Chinese all-weather, short-range surface-to-air missile system. It is designed to protect ground forces and vital installations from various aerial threats, including aircraft, helicopters, and cruise missiles.

Developed in the 1980s, the system was created by reverse-engineering the French Thomson-CSF Crotale surface-to-air missile system, which China had imported for evaluation in the late 1970s. The domestic variant, HQ-7, officially entered service with the People's Liberation Army in the late 1980s, with the FM-80 export version marketed shortly after. It was widely deployed to defend Chinese airfields and key infrastructure, and its naval variant became a standard point-defense weapon on PLA Navy warships during the 1990s. Though largely replaced in front-line Chinese service by more modern systems, upgraded variants remain in active service with several export nations, including Pakistan and Bangladesh.
