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.
