TheAN/BLQ-11 autonomous unmanned undersea vehicle (formerly theLong-Term Mine Reconnaissance System (LMRS)) is atorpedo tube-launched and tube-recovered underwater search and surveyunmanned undersea vehicle (UUV) capable of performing autonomousminefield reconnaissance as much as[1] 200 kilometers (120 mi) in advance of a hostLos Angeles-,Seawolf-, orVirginia-class[2]submarine.
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.In January 2006,USS Scranton successfully demonstrated homing and docking of an LMRS UUV system during at-sea testing.[3]
TheUSS Oklahoma City successfully launched the 8 m (20 ft) long vehicle for covert mine countermeasures in September 2005. The USS Scranton conducted 24 test runs in January 2006. In October 2007,USS Hartford conducted further tests.
The U.S. Navy's Mission Reconfigurable UUV System[4] (MRUUVS) program,[5] of which AN/BLQ-11 was a part, ended in December 2008 due to technical and engineering limitations.
