ABSTRACT:
A large caliber cannon such as a 155 mm Howitzer uses ammunition rounds consisting of a projectile and a propellant charge which are loaded in sequence into the breech of the cannon. The cannon is mounted on a gun carriage and is free to move in elevation on the carriage about an elevation axis. The carriage is controllable in azimuth for gun pointing. Storage drums for holding a plurality of projectiles and charges are mounted on the carriage. Projectile trays and propellant charge trays are positioned to receive the projectiles and their propellant charges from the storage drums. The trays are pivotally mounted on cradle arms so that they may be rotated between a receiving position and a gun loading position. The cradle arms are pivotally mounted on the gun carriage so that they may be moved between the elevation of the receiving position and a position in alignment with the breech when the cannon is being trained. A control is provided which actuates mechanism to transfer the projectiles and charges from the storage drums to the trays and from the trays to the breech. The control monitors the position of the system mechanical components and actuates them in appropriate sequence so that a series of ammunition rounds are delivered from the drums to the breech.
