PROBLEM TO BE SOLVED: To compose the controlling device of a missile that uses an infrared- ray image seeker that cannot detect approach speed, performs proportional navigation calculation, extends a range as compared with free trajectory flight, and at the same time improves lock-on probability. SOLUTION: The speed VM of a guidance bomb being calculated by an inertia navigation device 15 is used as the substitute of approach speed in proportional navigation calculation being performed at a navigation calculation part 5, and at the same time the output of 1G and 0G commands is controlled by a 1G control command generation part 17, a 0G control command generation part 18, and a G command pattern data table 19. Then, attitude in lock-on is calculated by a lock-on attitude angle calculation part 20, and the control command is outputted by the navigation calculation part 5 so that the attitude is achieved.
