The HY-1 and HY-2 received the NATO reporting name Silkworm. However, to confuse matters, Western media also referred to the SY-series, and its export derivatives as Silkworms.
The HY-2 features a round nose accommodating the radar seeker, a pair of mid-mounted delta wings on the middle section of missile body, and three tail control surfaces. The missile is powered by a liquid-fuel rocket motor, with a solid rocket booster attached under the missile fuselage.
The HY-2 is launched from land-based launcher and flies at an altitude of 1000 m during the initial stage of the flight. After the missile switched to the cruising mode, the flight altitude was reduced to 100 ~ 300 m. During the final stage of the flight, the missile switched on its radar seeker and dives to an altitude of 8 m until it hits the target. The single-shot hit probability is estimated to be 90%. Due to its oversized body, the HY-2 did not develop a ship-to-ship variant. The missile is obsolete and will be replaced by the YJ-8 series in the future.
