Abstract: A weapon system incorporating a barreled weapon, which is supported in a rotatable turret dome of an armored vehicle so as to be pivotable about trunnions in the direction of elevation, which can be loaded with projectiles from the armored vehicle, and wherein the base of the barreled weapon rests at its bottom on a rail which is circular in its radius relative to the axis of the trunnions. The barreled weapon is constructed as a front-loader weapon, and possesses outside of the armored vehicle a forward barrel segment which is separate from the weapon barrel and adapted to be latched with the latter, and which is rotatable about the trunnions up to contacting end stops.

Abstract: A pivoting or swivable projectile or shell loading chamber for high angle-firing weapons, especially for mortars, which is constructed so as to be barrel-shaped at its lower end and which support itself on the base plate of the mortar, and which can be swung with its upper end outwardly of a position extending coaxially with the weapon firing tube. The upper separating location between the firing tube and the pivoting projectile loading chamber is sealed through a gas pressure-controlled sealing ring. A locking lever is arranged in the upper region of the pivoting projectile loading chamber, which is in operative connection with locking components on the framework of the mortar and with trigger parts of the mortar, and wherein the opening angle of the pivoting projectile loading chamber is restricted by a stop.
