Surface Ship Torpedo Defense

Abstract

The Surface Ship Torpedo Defense (STTD), Project 0225, develops a detect to engage hardkill torpedo defense system called the Anti-Torpedo Torpedo Defense System (ATTDS) as specified in the Draft ATTDS Capability Development Document (CDD). This program uses an evolutionary acquisition strategy of providing incremental surface ship torpedo defense capability by implementing first on Cruisers and Destroyers (CRUDES) already equipped with sonar systems, fire control systems and launchers. At-sea demonstrations of the Torpedo Detection Classification and Localization (TDCL) systems conducted FY06 through FY09 led to a CRUDES TDCL draft system specification in FY09. At sea testing of the EDM-1 design of the Anti-Torpedo Torpedo (ATT) variant of the Common Very Lightweight Torpedo (CVLWT) in FY07 through FY09 facilitates completion of the EDM-2 design in FY10. The ATT will be shipped, stowed and launched from an all up round canister known as the Countermeasure Anti-Torpedo (CAT). In FY10, an EDM of the CRUDES ship systems will be developed. The systems will include, a command and control system with user interface, a modified Surface Vessel Torpedo Tube launcher, and a canistered ATT. The TDCL system will utilize a sensor set added to the AN/SLQ-25 (NIXIE) System, processing in the AN/SQQ-89, as well as the hull mounted sonar already employed on these ships. The development of the ATT is the first derivative of the CVLWT as an acquisition program. The CAT and the TDCL development are closely linked with the ONR Sea Shield Future Naval Capability (FNC) programs that provide advanced technology inserts at key transition points. FY09 Congressional Add-Project 9D21A: Develop the Open Architecture (OA) supportability processes, methods, and tools required to facilitate the real-time capture and cataloging of sailor training, performance, and vocational skills data. FY09 Congressional Add-Project 9D22A: Expand technology development of mobile countermeasures used for Surface Ship Torpedo Defense including device engineering, fabrication and testing capabilities to assess the effectiveness of Next Generation (mobile) Countermeasures. FY10 Congressional Add-Project 10C097, Continuous Active Sonar for Torpedo DCL Systems: Adapt Continuous Active Sonar (CAS) and other active and passive sonar technologies that have proved very effective for active ASW applications, to improve TDCL capabilities and extend ATTDS coverage against most stressing emergent threats. FY10 Congressional Add-Project 10C096, AN/SLQ-25D Integration: Provide integration of the SLQ-25D countermeasure system with the Anti-Torpedo Torpedo Defense System. This integration includes development of interfaces with Ship's Sonar and Fire Control systems, as well as integration with new towed sensors and integration with the ship itself.
