WASHINGTON, 13 Dec. 2010. Submarine electronics experts at Sedna Digital Solutions LLC in Manassas, Va., will provide the U.S. Navy with submarine defensive warfare systems that enable U.S. ballistic missile and fast attack submarines to respond automatically to torpedo attacks under terms of a $14.3 million contract announced last week by Naval Sea Systems Command in Washington.

Sedna Digital Solutions will provide the Navy with AN/WLY-1 acoustic interception and acoustic countermeasures systems for U.S. submarines. The AN/WLY-1 has threat platform sonar- and torpedo-recognition capability for early detection, classification, and tracking of torpedo threats to Navy submarines.

This submarine defensive warfare system , which allows radius of curvature and multipath ranging, also has a control subsystem for launch management of all onboard countermeasure devices and launchers.

The Navy's contract to Sedna Digital Solutions is a modification to a previously awarded contract, also includes pre-cable kits, maintenance assistance modules, and spare parts.
