A cover closes off the open end of a missile launch canister. The cover is esigned so as to seal off the interior compartment of the canister to protect the missile or the like contained within it from moisture, contaminants and the conflagration created by nearby fired missiles. The cover is designed to maintain a minimum vapor pressure within the canister for storage purposes and to burst prior to contact by the nose of the missile contained within the canister upon the occurrence of a predetermined accumulation of vapor pressure within the canister after firing of the missile or the like. The cover is formed of a laminate of fiberglass cloths having an electromagnetic interference shield and vapor barrier adhered to the interior surface of the cover. A layer of rubber protects the fiberglass laminate from scratching or puncturing and a polyurethane layer over the rubber layer provides a moisture seal as well as insulation from other contaminants. An aluminum ring is used to secure the cover to the canister.

[ What is claimed is:] [1.] In the combination of a canister for containing a missile or the like wherein the canister includes a closed end and an open end through which the missile or the like exits, and a cover for said open end for closing off said open end to protect the missile or the like from corrosion due to moisture and from other deleterious effects, and improved cover comprising:means comprising a disc of burstable material having no pre-formed tear lines for sealing said open end of said canister so as to maintain a predetermined inert vapor within said canister during storage of said missile and for bursting when said missile or the like is fired upon the accumulation of a precise predetermined maximum vapor pressure within said canister so as to vent off said vapor prior to the occurrence of pneumatically caused damage to said missile or the like.
