    Abstract: A missile launch system is described in which a missile launch tube has the launch end thereof protected by a hollow launch tube cover. The launch tube cover is divided into a plurality of segments which are frangible and are dispersed during launch of a missile 62. The surfaces of the individual segments are coated with water repellant material such as tetrafluoroethylene or silicone to prevent ice buildup. Moreover the outer surface of the head of the launch tube cover can be coated with a layer of metallic material to prevent electro magnetic interference or radio frequency interference. The launch tube cover is constructed of a light weight, water proof material such as an expanded closed cell foam including polyurethane foam.
