A protective sheath for projectiles, consisting of a sleeve (11) whose wall (14) consists of a material which reacts endothermically under the influence of heat, foams up under the influence of heat and, by means of heat absorption and heat insulation, prevents heat reaching the projectile (12). Reinforcement (18, 20) consisting of a wire mesh ensures adequate mechanical strength during storage and in the event of a fire. <IMAGE>
