Chinese Defence Today - CY-1 Anti-Submarine Rocket

The ChangYing-1 (CY-1) is an anti-submarine missile similar to the U.S. Navy ASROC. There is little information available regarding the development history, performance, and exact status of the missile, but it is understood that a small number of the missile was deployed on the PLA Navy Type 051 (Luda class) destroyers and Type 052H2G (Jiangwei-I class) frigates. The CY-1 is basically an anti-submarine torpedo (Yu-4?) delivered by a ballistic rocket. The delivery vehicle features four small stabilising fins and four control surfaces, and is powered by a solid-fuel rocket motor. The weapon is possibly comparable to the ASROC in general performance.
