Surface Ship Torpedo Defense
Abstract
The Surface Ship Torpedo Defense (SSTD) program provides a detect-to-engage hardkill torpedo defense capability through two 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. Additionally, the program will require fielding of the AN/SLQ-25X (NIXIE) (Previously identified as AN/SLQ-25D) system as a tow point for the TWS towed sensors. This requires interfacing NIXIE power and data transfer with the TWS. The program will focus on first providing torpedo defense capability to High Value Units (HVU). The SSTD system will be installed on one CVN and one Combat Logistics Force (CLF) ship (both HVUs) with initial operational capability (IOC) in FY 2018. Additionally, the program will develop and field six surface ship torpedo defense prototype systems (TWS/CAT) on CVNs. Each prototype consists of one TWS and 10 CATs. The 6 systems are required to be accelerated due to the lack of torpedo defense on HVUs which has been exacerbated by recent real-world events and evolving threats. The systems provide a hard-kill torpedo defense capability in advance of the IOC as part of the program of record. To accomplish this effort, the department reprogrammed $9.9 million of FY 2010 funds and received a prior approval reprogramming for an additional $7.9 million of FY 2010 funds. The first two prototypes are expected to deliver in FY14, two systems in FY15, and two systems in FY16. Finally, the program will deliver one hybrid prototype system in FY 13. This is in addition to the six prototype systems discussed above. The system will deliver some capability to a forward deployed CVN asset before the first prototype system is available. 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 FY18 as most acceptable risk for delivery. Successful at-sea testing of the Anti-Torpedo Torpedo Engineering Development Model (EDM-1) in FY06 through FY09 facilitates completion of the ATT EDM-2 design in early FY12. The EDM-2 design will be the ATT included in the six fielded prototype systems.

- Change Summary Explanation
- Technical and Schedule: Congress reduced FY 11 funding due to MS B delay. Added FY 10 funds in support of surface ship torpedo defense (SSTD) prototype systems commensurate with PB 12 program redirection. Accelerated the IOC for CAT from FY 2021 to FY 2018 and delayed the IOC for the TWS from FY 2017 to 2018 to better align capabilities. Added funds in FY 2103 to support the hybrid prototype system.
