A torpedo recovery system is provided with a hull and a float conformable on a host vehicle and lifting wire coiled on a spool attached by an extension spring as well as with an anchor to the float. An oval hole penetrates the recovery system hull at positions lined with a watertight sleeve. The spool can accommodate a locking pin. The extension spring allows compliance for take-up of the spool by having the locking pin mate with an aperture and adds a wire pre-tension. Upon vehicle shutdown; the locking pin is retracted to free the spool from a rotational constraint. The float buoyancy translates into pulling the wire from the spool with the float and extension spring continuing to the water surface. Once the float reaches the surface; the float provides a visual location for the host vehicle. The float is retrieved and a winch can recover the lightweight torpedo.

The present invention is broadly directed to an unmanned surface vessel (USV) 10 broadly comprising: 1. a vessel body (12) adapted to contain a payload (14); 2. a front fin (16) and a rear fin (18) connected to and protruding from the vessel body (12); 3. a forward foil (20) and a rearward foil (22) connected to a distal end region of the respective front and rear fins (16) and (18); 4. propulsion means (24) operatively coupled to the rear fin (18) for propulsion of the fin (18) and the foil (22) through the water.
