PURPOSE: To increase mounted number of missiles in a mounted chamber, and further increase capability of intercepting a high altitude target and a capability of being induced at a lows speed, by providing a means for supplying a high tension power to nozzle electronic mechanical actuation means and a fin electronic mechanical actuation means.

CONSTITUTION: Fin span 54 is decreased such that a missile 10 has the fin span 54 of about 4 inch or less in order to increase a shooting distance and further increase mounted missiles. Hereby, many missiles having the same case diameter 54 can be mounted in a loading chamber. Further, in a multiple pulse missile having thrust directional control an f.pole is influenced by determination as to whether or not all pulses remaining during an intermediate course of flying is fired, or of whether or not it is kept unchanged without firing a final pulse until a final process is reached. Thus, when the height of the target is higher than a point 64, the high altitude target can be shot by firing a final pulse in a final process.
