ABSTRACT:
A mortar munition includes a mortar tube; first and second openings in the wall of the mortar tube, the first opening being closer to a breech end of the mortar tube than the second opening; a spring loaded valve assembly disposed in the first opening in the wall of the mortar tube; and a shoe assembly disposed in the second opening in the wall of the mortar tube.
