TheAN/BLQ-11 is anautonomous unmanned undersea vehicle (UUV) formerly calledLong-Term Mine Reconnaissance System (LMRS). It was developed byBoeing Defense, Space & Security for theUnited States Navy. The LMRS is atorpedo tube-launched and tube-recoveredunderwater search and survey vehicle capable ofautonomousnaval minefieldreconnaissance as much as 120 miles (190 km) in advance of its hostLos Angeles-,Seawolf-, orVirginia-classsubmarine.[1] LMRS is equipped with both forward-lookingsonar and side-scansynthetic aperture sonar.
Boeing concluded the detailed design phase of the development project on 31 August 1999. TheUSS Oklahoma City (SSN-723) successfully launched the 20-foot (6.1 m) long vehicle forcovertmine countermeasures in September 2005. In January 2006sea trials, theUSS Scranton (SSN-756) conducted 24 test runs successfully demonstrating homing and docking of an LMRS UUV.[2] In October 2007,USS Hartford (SSN-768) conducted further tests.
Due to technical and engineering limitations theU.S. Navy's Mission Reconfigurable UUV System (MRUUVS) program, of which AN/BLQ-11 was a part, ended in December 2008.[3][4]
