Cannon breechblock insert assembly

摘要

A sliding breechblock for a cannon includes a translatable, removable insert assembly that contains electrical firing pin and data link modules. The removable insert assembly is translatable in a direction normal to the central longitudinal axis of the barrel thereby enabling removal of the insert assembly without removing the breechblock from the breech ring. Mating portions formed on the breechblock and on the insert assembly prevent displacement of the insert assembly with respect to the breechblock in the direction along the central longitudinal axis of the barrel.
