The fast-attack submarine USS SCRANTON (SSN-756) successfully demonstrated homing and docking of an Unmanned Undersea Vehicle (UUV) system during at-sea testing in January 2006.
The two UUVs used in the testing are a part of the AN/BLQ-11 Long Term Mine Reconnaissance System (LMRS), which was designed to enable submarines to conduct clandestine undersea surveys to locate mines.
Repeated homing tests were conducted with slightly different configurations to assess the ability of a UUV to dock with a torpedo-tube-mounted recovery system. The final result was the first successful docking of the LMRS vehicle to a submerged submarine at-sea.
After the UUV is launched from the submarine’s torpedo tube, it transits to a series of pre-programmed waypoints. Meanwhile, the submarine maneuvers to rendezvous with the UUV.
Homing and Docking sonar guides the UUV towards the recovery arm, a unique docking mechanism that extends out of the ship’s upper torpedo tube. After the UUV is captured, the recovery arm guides the UUV into the lower torpedo tube, and back into the submarine.
