ABSTRACT:
Forward underwater movement of a sea craft at a high speed induced by propulsion thereof is decelerated and stopped by projection of drag devices, mounted on a fully submerged underwater sea craft hull, from retracted positions within said sea craft hull or the steering rudders positioned thereon. Each of the drag devices has an elongated drag plate with an end surface cap flush with the outer surface of the hull or the steering rudder in the retracted position of the drag device.
