ABSTRACT:
A device for providing fold out fins for stabilizing projectiles or missi which may be tube-launched. The missile is provided with a tubular element or cup which has a plurality of slots defining fin-like stabilizing flaps. The slots extend circumferentially around two sides of the flaps; a third slot interconnects the circumferential slots, while a fourth side is unslotted. Since the tubular element is in fluid communication with the pressure within the launcher, the stabilizing flaps or fins expand outwardly into position about the fourth unslotted side as the missile or the projectile leaves the launcher.
