HY-4
plan_hy-4ASMChina
The HY-4 is a Chinese derivative of the HY-2 missile, with a turbojet engine replacing the original liquid-fuel rocket propulsion. This allows for a significant improvement in range, although the ungainly airframe of the HY-4 means it flies at a relatively high altitude and slow speed for much of its flight.
