Surface Ship Torpedo Defense
Abstract
The Surface Ship Torpedo Defense (SSTD), Project 0225, has changed as presented in the President's Budget FY 2011 submit. The previous program developed the Anti-Torpedo Torpedo Defensive System (ATTDS) for Cruisers and Destroyers. This program had a planned Initial Operating Capability (IOC) in 2015. The program will now focus on first providing torpedo defense capability to High Value Units (HVU). The project now uses technologies developed under the previous ATTDS program to provide a detect-to-engage hardkill torpedo defense capability through two new development programs. The Countermeasure Anti-Torpedo (CAT) program develops a canisterized Anti-Torpedo Torpedo (ATT) as an ACAT II program. The Torpedo Warning System (TWS) develops the required ship systems as an ACAT III program. Like the previous ATTDS system, the new TWS system will require fielding of the AN/SLQ-25D (NIXIE) system as a tow point for the TWS towed sensors. This will require interfacing NIXIE power and data transfer with TWS. The first increment of the TWS system will be installed on one CVN and one Combat Logistics Force (CLF) ship (both HVUs) with an IOC in FY 2017. The first increment of the CAT will be installed on HVUs in FY 2021. Additionally, the program will develop and field two surface ship torpedo defense prototype systems (TWS/CAT) on two CVNs. To accomplish this effort, the department intends to request a FY 2011 prior approval reprogramming for approximately $38 million. The effort will complete 33 months after funds are received. At-sea demonstrations of the Torpedo Detection Classification and Localization (TDCL) systems conducted in FY06 through FY09 led to a CRUDES TDCL draft system specification in FY09 which is being modified to accommodate installation of a system for HVUs. Additionally, in 2nd Qtr FY10, prototype TDCL systems were tested at sea to collect data to characterize the ability of towed active and passive sonar arrays to detect and track threat targets both actively and passively in adverse conditions. System manufacturing readiness levels indicate FY17 as most acceptable risk for delivery. At-sea testing of the Engineering Development Model (EDM-1) design of the anti-torpedo torpedo capability in FY06 through FY09 facilitates completion of the EDM-2 design in late FY11. Development and testing conducted by the Office of Naval Research (ONR) provided the required Technology Readiness level required for the CAT program to achieve a Milestone B. A Performance specification for the AN/SLQ-25D system suitable for the HVU application was completed in FY10. Since the HVU does not use the Surface Vessel Torpedo Tubes (SVTT), the previous ATTDS efforts conducted to modify this system to accept the CAT have been terminated, and efforts have commenced with the planning yards for CVNs to establish locations and requirements for launcher systems appropriate to these ships. FY10 Congressional Add-Project 10C096, AN/SLQ-25D Interface: Funding provides interoperability of the AN/SLQ-25D countermeasure system with the TWS. This interoperability requires development of interfaces with Fire Control systems, as well as interfaces with new towed sensors. This task has increased in scope as the HVU application increases the requirements placed on the towed sensors. This increase resulted in the program office's decision to compete the development of this capability. Award of the new competitive contract is expected in June 2011. 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 Anti-Submarine Warfare (ASW) applications, to improve TDCL capabilities to extend coverage against most stressing emergent threats. The products of this Congressional Add could result in potential future increased capabilities for the CVN application.
