ABSTRACT:
A rotary breech mechanism (10) is provided for loading large caliber guns. The mechanism comprises a rotary transfer member (12) which is cylindrical and mounted in the gun barrel (16) near the breech end (18). A hole (14) through the rotary transfer member (12) is aligned either with an ammunition magazine tube (48) for loading or with the gun barrel (16) for firing of a projectile (20). Once the projectile (20) has been fired, the rotary transfer member (12) is rotated to accept the next projectile, no matter what position the gun is in. The azimuthal orientation of the barrel (16) does not affect the operation of the loading mechanism.
