Abstract: In this paper, the functions and the standings of various kinds of powerplants in cruise missiles are described historically. With the development of cruise missiles and the rigorous requirement of their technical and tactical performances, they are tending towards supersonic and hypersonic speed (Ma>2-6), medium-high altitude (H>15-40km)or very low altitude (H<30-100m) and medium-low rang (L>100km). Meanwhile the aerospace technology is also stepping into the hypersonic age from subsonic and supersonic, which maens missile and aerospace technology has approached a new period that ramjet can be used at their optimum operation condition. In order to meet the requirements of the new generations of cruise missile and civil/military hypersonic vehicles in next decades, a new kind of powerplants would be developed so that they could be endowed with lighter weight, lower volume, higher speed, longer range and better maneuverability, so to say, ramjet and its combined propulsion technology are the optimum options. Now ramjet propulsion technology itself has approached to be mature and GM and aerospace technology will also offer a new area to it.So a new period that ramjet and its combined propulsion technology will grow vigorously all over the word is coming.
