HY-3 (CSS-C-6 Sawhorse) Chinese Short-Range Anti-Ship Cruise Missile

The HaiYing-3 (HY-3, also known as C-301 in its export name; NATO codename: CSS-C-6 Sawhorse) is the active radar homing, ramjet-powered supersonic land-to-ship missile developed by China Haiying Electro-Mechanical Technology Academy (CHETA, also known as 3rd Space Academy). The missile was developed in the 1980s based on the design of the HY-2 (C-201) and the ramjet technology of the cancelled YJ-1 (C-101). The development was completed in the early 1990s but the missile did not enter service. The HY-3 is a large-size missile with a slim forward body and sharp nose, and a fatter rear half with four solid rocket boosters and two ramjet engines located aft of the missile body. There are a pair of front-canards on the front fuselage, four control surfaces on the rear fuselage, and four smaller stabilizing fins attached on the solid rocket boosters. The booster motors accelerate the missile to past Mach 1.8 and the kerosene-fueled ramjet engines accelerate the missile to a cruise speed of Mach 2.0. Its range is variously reported as up to 130 km, and it can fly as low as 50 m in its terminal attack phase. The missile is programmed to dive from cruising altitude to under 30m before the active-radar terminal phase begins, then dive onto the target just prior to impact. The 3.5 ton missile is launched from a land-based launcher. Each firing unit consists of four launchers, a target acquisition radar, a fire-control unit, a power unit, and 8~12 missile reloading vehicle (each with one missile).
