Abstract
Apparatus for controlling the underwater course of a submarine-launched mile, by which gas contained within the missile body is vented from the interior of the missile, through ports in the missile exterior, into the water to alter the water pressure distribution over a portion of the exterior surface, thereby producing a desired pitching moment and resulting missile movement.
