ABSTRACT:
One or more docking cages releasably attached to a tow line extending from the stern of a retrieval ship, emit tracking beacon beams picked up by sensors in unmanned underwater sea craft vehicles being approached, for steered propulsion thereof into rammed hook attachment to the cages. A sea craft vehicle thereby releasably attached to a cage, is towed onboard the retrieval ship by storage reel-in of the tow line, which is then disconnected from the cage and the retrieved vehicle for subsequent use in retrieval of other unmanned sea craft vehicles.
