A cover for sealing a munition within a canister has an inner layer of tempered glass bonded by an adhesive to an outer layer of structural foam having at least one score mark thereon. Upon launch of the munition, the inner layer of tempered glass breaks into numerous fragments which remain bonded to the outer layer of scored foam by the adhesive layer. The outer layer of foam then breaks along its score marks into two or more pieces that have pieces of the inner layer of glass bonded thereto. The pieces of foam with glass fragments bonded thereto are then blown out and away from the canister so that the munition can egress unimpeded and undamaged from the canister. A method for sealing a munition within a canister until munition launch includes the step of sealing the munition within the canister by a cover having an inner layer of tempered glass bonded by an adhesive to an outer layer of structural foam having at least one score mark thereon. Upon munition launch, the method further includes the steps of breaking the inner layer of glass into numerous fragments, which remain bonded to the outer layer of foam by the adhesive layer; breaking the outer layer of foam along its score marks into two or more foam pieces each having glass fragments bonded thereto; and removing the pieces of foam with the glass pieces bonded thereto from the proximity of the munition. Thus, the munition can egress unimpeded and undamaged from the munition canister.

[ What is claimed is:] [1.] A canister assembly for containing a munition until munition launch, said canister assembly comprising:a hollow canister having an open end, the canister being adapted to receive a munition therein; anda cover for sealing the open end of said canister, the cover being a laminate comprising: a glass layer having first and second surfaces; a structural foam layer having first and second surfaces; and an adhesive layer in contact with the first surface of said glass layer and the first surface of said foam layer, whereby said adhesive layer bonds the first surface of said structural foam layer to the first surface of said glass layer, the cover being positioned such that the second surface of said structural foam layer faces outwardly away from the open end of said canister and the second surface of said glass layer faces inwardly toward the interior of said canister,whereby said cover seals the open end of said hollow canister to thereby seal a munition within said canister until munition launch, whereupon said cover can break out and away from said canister to thereby allow the munition to egress from said canister.
