A rear cover for a rocket launch tube which is normally closed and which is capable of breaking away successively in one or more sections in response to the pressure and diameter of the rocket exhaust column or plume. The cover is so arranged that it will successively increase the area interconnecting the launch tube for the rocket with an exhaust duct or manifold as the rocket plume increases in diameter. The cover of an adjacent launch tube which is normally closed will prevent the exhaust gases from entering the launch tube of a stored rocket or the like. |
