A capsule adapted for disposition in a submarine launch tube for retaining the missile until launch thereof. The capsule includes a cylindrically shaped housing including a plurality of layers of glass fibers and layers of graphite, the layers including an outer layer of glass fibers defining an outer skin of the housing, and an inner layer of glass fibers. A titanium flange is fixed on the housing and in contact with the layers of graphite. An adhesive layer is disposed on the outer skin and an interface support pad is mounted on the outer skin and retained thereon by the adhesive layer. A layer of metal foil is disposed inboard of the adhesive layer and between the outer layer of glass fibers and the inner layer of glass fibers, to serve as a barrier to products of galvanic reaction occurring between the graphite layers and the titanium flange.
