SY-2The liquid fuel engine was rather hazardous and unreliable, so a solid fuel rocket engine was developed. This engine also made it possible to reduce the size and weight of the missile while providing greater range.[1]
HY-1The HY-1 received two separate NATO reporting name, the CSS-N-2 Safflower for the ship to ship version and the CSSC-2 Silkworm for the land based coastal defense variant. The HY-1J was intended for use on the Type 051 destroyers.[1]
HY-2The HY-2 is identical to the HY-1 but with a further stretched body. The missile 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.[1]
HY-3The 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…[1]
HY-4The HY-4 development of the C-201 is a mid-range ground-, air-, and ship-launched cruise missile. Development of the C-201 HY-4 is believed to have started in the mid-1970s, replacing the C-201 HY-2 liquid propellant sustainer motor with a small turbojet…[1]
FL-1The FL-1 (NATO designation CSS-NX-1) was a SY-1 with a high-frequency monopulse seeker. It used a radar altimeter to cruise at 30 metres.[1]
FL-2The FL-2 anti-ship missiles was the land-based derivative of the SY-2. It was produced at the Nanchang Aircraft Factory[1]
SFQ-1SFQ-1 was an unarmed test vehicle derivative of the Silkworm missile family. The test vehicle was used in the Chinese development of small turbojets that were designed to improve the range of the Chinese anti-ship cruise missiles, as well as powering the…[1]
