ABSTRACT:
Missiles located in the deeper (hard rock) portion of a shaft or tunnel are protected from damage during a nuclear attack by a mass of ice, preferably trumpet-shaped, located in the outermost portion (e.g., 600-900 meters). When missile egress is required, an ice-supported passageway is bored through the ice, preferably by melting. The trumpet shape assures a straight path for missile egress even if the shaft or tunnel should become transversely displaced by a cratering explosion against the surface.
