The US Naval Undersea Warfare Center Division has awarded a contract to DRS Sonar Systems to provide a towed active subsystem for use on the littoral combat ship (LCS).

The towed active subsystem will be integrated into a variable depth sonar (VDS) anti-submarine warfare (ASW) system for use on the ship.

The LCS VDS is a low-frequency sonar capable of detecting submerged submarines off the coast and in deep waters.

The sonar also provides a high-search-rate tactical anti-submarine warfare capability.

The $9.7m fixed-price contract includes options which, if exercised, would bring the cumulative value to $12.7m.

The LCS VDS advanced development model (ADM) is scheduled for a sea test in financial year 2012.
