TITLE OF THE INVENTION Projected image target apparatus. ABSTRACT OF THE DISCLOSURE Projected image target apparatus for gunnery and missile launcher training, comprising a screen onto which a motion picture target is projected from a projector, a light beam projector provided on the weapon for projecting onto the screen an invisible light beam along the line-of-sight of the weapon, a light beam projector for projecting a visible light beam onto the screen and control means for controlling the projector and light beam projectors, the control means including means for tracking movement of the beam of invisible light and means which upon firing of the weapon automatically discontinues the tracking and utilizes the position that the invisible beam of light had at the instant of firing the weapon as a datum relative to which the visible light beam is moved automatically in accordance with the ballistic performance of the projectile to simulate trajectory drift and fall of the projectile over the simulated range of the target projected onto the screen and the film may be stopped in the projector a predetermined period of time after the firing of the weapon to simulate the travel time of the projectile over the simulated range, the beam of visible light then indicating on the screen the point of impact relative to the projected target image.
