Abstract
A large-caliber weapon includes a barrel having a longitudinal barrel axis; a cradle supporting the barrel; a breech ring mounted on an end of the barrel; a breech wedge disposed in the breech ring for linear displacements transversely to the barrel axis; a control lug affixed to the breech wedge; and an opening lever pivotally mounted on the cradle for angular displacements about a lever axis oriented perpendicularly to the barrel axis. The opening lever is disposed externally of the breech ring and has an initial position and an actuated end position. The opening lever is engaged by the control lug of the breech wedge in a position of rest of the barrel such that upon motion of the opening lever from its initial position to its actuated end position, the breech wedge is moved from a closed position into an open position. Further, an external drive is provided which is mounted on the cradle and a mechanical coupling mechanism connects the external drive to the opening lever for effecting pivotal motion of the opening lever.
