The AN/BLQ-11 autonomous unmanned undersea vehicle (formerly the Long-Term Mine Reconnaissance System (LMRS)) is a torpedo tube-launched and tube-recovered underwater search and survey unmanned undersea vehicle (UUV) capable of performing autonomous minefield reconnaissance as much as 200 kilometers (120 mi) in advance of a host Los Angeles-, Seawolf-, or Virginia-class submarine.
Boeing concluded the detailed design phase of the development project on 31 August 1999. In January 2006, USS Scranton successfully demonstrated homing and docking of an LMRS UUV system during at-sea testing.
