ABSTRACT:
A cap for a rocket exit opening of a mobile rocket launcher for a submarine which is guided to the surface of the water in order to launch an air rocket which pushes out the cap when it is launched. The cap includes pressed together cap segments for covering the exit opening of the mobile rocket launcher. The cap segments are shaped so that externally applied force components which are radial with respect to the longitudinal axis of the submarine act on the segments. The cap segments present a peripheral edge which cooperate with the peripheral edge of the exit opening to form a form locking plug-in connection with one another which is held together by external force components acting in the axial direction of the submarine. A tear-away, pressure resistant, slightly elastic and watertight, thin sheet adapted for attachment to the submarine is stretched over the cap segments when it is attached to the submarine.
