Mid-course guidance is inertial, with active radar during the terminal phase. The radio altimeter-controlled cruise altitude is around 60 ft, followed by terminal phase of between 15 and 20 ft. Performance of the missile in past conflicts have proven its accuracy and reliability. This matchup goes to the PLAN for a longer range and more powerful missile. The missile has a radio altimeter which allows the cruising altitude to be varied between 220 ft and 640 ft.
Terminal attack is a pop-up followed by a steep dive onto the target.
It has a very large and powerful warhead, which can inflict crippling damage to the largest of ships. The drawbacks of the missile include its large size, slow speed, and the lack of agility, making defense with a CIWS relatively easy. It is composed of the HY-1 missile body, with two ramjet engines mounted on opposite sides, near the aft of the missile. Fins were also altered to handle the change in aerodynamic requirements. It is believe the missile features a 660 lb, semi armour-piercing warhead with a delayed impact fuse.
