The Kai Shan - 1 (KS-1) is the first Chinese surface-to-air missile to adopt a phased array radar.
The missile is roughly the Chinese equivalent of the American MIM-23 HAWK, except it was designed to engage missiles as well as aircraft. This unique design feature means that it is the first Chinese SAM to adopt an indigenous planar passive phased array radar, designated the H-200, which can simultaneously track multiple targets 100+ km away, and can guide 6 missiles to 3 targets at the same time (2 missiles at each target).
The first successful test-fire of the missile was in 1989, KS-1 development was complete in 1994. The missile was first publicized in 1998 at the Zhuhai Airshow. An improved version, the KS-1A, which greatly reduced its minimum altitude and range, has already been developed and first appeared at the Sixth Zhuhai Airshow in 2006. It was rumored that this improvement also increased its ability to engage targets maneuvering at a higher g force.

Standard deployment of a KS-1 SAM battery typically includes:
- 1 H-200 Planar Phased array radar
- 4 launchers, each with 2 missiles
- 24 missiles
- Other support equipment
