C-201 / HY-4
CSS-C-7 / SADSACK

The HY-4 variant 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 engine, and adding a the monopulse active radar seeker. Apart fromt the substitution of the turbojet engine, the overall configuration of the HY-4 variant of the C-201 missile is similar to the HY-2 variants of the C-201, with two delta wings and triform rudder and tail. The missile has a radio altimeter which allows the cruise height to be varied between 70 and 200 m altitude, followed by a steep dive onto the target. Reports suggest that an improved version of the HY-4, known as XW-41 is no in development.
