Abstract: Disclosed is an ordinance-launching tube, including a rear door and an expulsion circuit between a source of pressurized fluid and the tube, and provided with a unit for closing this circuit having an actuator that can be maneuvered by an operator in order to permit the expulsion, the actuator being associated with a detector for the presence of the rear door in the tube-closing position and with a lock for this rear door in the tube-closing position, which can be actuated via a bolt that the operator can move between a first position preventing expulsion and a second position permitting expulsion when the door is in the closing position and locked. The bolt includes an abutment movable between a position blocking the actuator in position to prevent expulsion, and a position releasing the actuator so that they may be actuated by the operator, and thus permit expulsion.

Abstract: Disclosed is a weapon tube and particularly a torpedo tube structure including a system for holding the weapon in a storage position in the tube, including a clamping mechanism which is connected to the structure and can be moved by an actuator between a closed position for locking an interface part of the weapon in order to lock the weapon in position in the structure and an open position for releasing the interface part and therefore the weapon, the structure includes an elastic unit for soliciting the clamping mechanism in the closed position.
