Disclosed is an ordnance-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.

A method and device are provided for launching a payload from water, including a launching tube having inside walls, outside walls, a top and an inlet at the tube bottom, with the tube anchored to the bottom water surface. The tube includes a nozzle or neck inlet to the bottom and an open top outlet. A gate valve at the inlet is opened by remote control signals; or an explosive plug at the inlet is removed by an explosion initiated by remote control. The launching tube loaded with a payload and air filled and empty of water is installed in water with the inlet and the tube bottom proximate to the bottom water surface deep below the tube top, which is positioned above the water surface.

A launch container apparatus for ejection from a submerged launch platform and a method for ejecting a launch container apparatus are disclosed. The apparatus comprises an enclosure for carrying an unmanned aerial device and a surfacing sensor configured to generate a control signal in response to detection of surfacing of the launch container apparatus. Petals are configured to provide buoyancy and stabilization for the launch container apparatus are also provided. A petal drive mechanism moves, in response to the control signal, the petals from a folded position to an expanded position.

In a method of carrying a munition on a munition launcher platform, the munition launcher platform is provided with a data tag activator and a data tag reader. A munition is attached to the munition launcher platform, the munition being provided with a data tag. An activation signal is transmitted from the data tag activator to the data tag. As a result of receiving the activation signal, the data tag returns a data response to the data tag reader. The receiving of the data response provides the munition launcher platform with an indication that the munition is still attached to the munition launcher platform.

A projectile launching apparatus for launching projectile with the pressure exerted by the seawater. The projectile launching apparatus includes a large barrel launch, a piston, one or more piston stoppers, plurality of hinged doors, piston locks, and a plurality of water pump is available at bottom of the barrel to generate pressure and help to launch the projectile, wherein the assembly for the projectile is less expensive than present systems, lighter in weight, and of less complexity.
