In order to stabilize them during their flight.

Actually, that's not quite right. Missiles have movable "wings" (a better term for them is "fins"), whose primary purpose is to steer the missile onto target. Most missiles' fins are attached to the main body on a small rotating disk. The missile's guidance package sends commands to each fin, rotating the entire fin up or down slightly, to change the airflow over the fin, and thus change direction of the entire missile.

Standard dumb bombs have fins which are not movable, and serve to stabilize the bomb when dropped, in the same way that feathers on an arrow stabilize it in fight. Modern "smart" bombs work identically to missiles, minus the rocket motor.
