Abstract: An apparatus for launching an object in a fluid environment having a tubular member with a forward muzzle end, an opposed rearward end. The object is positioned in the tubular member. Ends of the tubular member are closed by expellable members. Flood valves are located on the expellable members and, on activation, allow flooding of the tubular member by external fluid. A propellant device and an object contact member are disposed within the tubular member. When the propellant device is activated, the object contact member moves the object. These actions are controlled by a control device which first causes the flood valves to enable fluid to flood the interior region. Next, the control device causes the expellable members to be expelled from the tubular member. The control device then causes the propellant device to generate gas in a predetermined manner launching the object from the tubular member.

Abstract: A launch assembly having an elastomeric tube for launching a device is disclosed. To launch the device an outboard end of the tube is movable outwardly along the length of a housing by an extending device, while the inboard end of the tube is restrained by a release mechanism and remains stationary. Thus, as the outboard end moves and the inboard end remains stationary, the elastomeric tube elongates. The tube may be elongated a predetermined amount, at which time the inboard end of the tube is released by the release mechanism. Releasing the inboard end allows it to travel toward the now stationary outboard end with a sufficient velocity to launch the device. The amount of elongation of the tube is related to the amount of possible launch energy. Thus, greater elongation of the tube provides a greater launch velocity, while shorter elongation provides a reduced launch velocity, as desired.

A tethered homing signal seeking UUV is guided toward the homing signal. Capture arms on the tethered homing signal seeking UUV engage the capture cable and guide the capture cable to one of several cable snagging eye-members. The winching cable is then winched back into the torpedo tube thereby drawing the untethered submarine tube-retrievable UUV into the torpedo tube.

The cells are engineered to have specific functional capabilities, e.g., acoustic sensing cells, communications cells, munitions cells, control cells and motive cells, and are electromagnetically attached to the vehicle. The functional arrangement of the cells types and the number of layers will be dependent on the desired capabilities and the overall mission of the vehicle. Cells may be deployed from the vehicle individually or in functional groups by decoupling appropriate cells from the vehicle. Once decoupled, motive cells can transport themselves and other cells as necessary, to positions remote from the vehicle. Groups of cells can be deployed to specific locations and arrayed in specific configurations by motive cells, allowing the vehicle to remain in a standoff position.

Abstract: A system for recovering submerged devices uses two recovery tubes of an underwater recovery vehicle. A recovery member is disposed within a first recovery tube. A second recovery tube receives the submerged device. To recover the submerged device, the recovery member is extended from the first recovery tube.

Because the recovery member is not disposed within the same recovery tube that is used to house the retrieved submerged device, the submerged device may have an outer diameter approximately equal to the inner diameter of the recovery tube.
