The US Naval Underwater Warfare Center (NUWC) in Rhode Island has placed a contract with Sonardyne Inc., Houston for the supply of an additional Sentinel Intruder Detection Sonar system.

The announcement follows the completion of rigorous acceptance and readiness trials by NUWC in 2008 when Sentinel was shown to meet the US Navy’s performance requirements for diver detection. The latest contract adds an additional Sentinel system as part of the new Integrated Swimmer Defence System led by the Program Executive Office, Littoral Mine Warfare (PEO-LMW – PMS480) and was delivered to NUWC in March 2009.

Sentinel is a compact underwater surveillance sonar that automatically detects, tracks and classifies subsea targets including surface swimmers, divers and vehicles. Operating autonomously or as part of an integrated security system that might also incorporate surface radar and electro-optic devices, Sentinel provides users with complete subsea domain awareness for any marine asset or water-side infrastructure vulnerable to underwater attack. This can include vessels, ports and harbours and offshore energy facilities.

“This latest contract from the US Navy confirms Sentinel’s reputation as an affordable system with proven capability that is ready for operational deployment.” He added, “It is also recognition of the considerable investment in people and system development undertaken by Sonardyne and NUWC.”
