Surface Ship Torpedo Defense

Abstract

The Surface Ship Torpedo Defense (SSTD) program provides a detect-to-engage layered torpedo defense capability. It is comprised of four major efforts, the AN/SLQ-25 (NIXIE) system, Torpedo Warning System (TWS), the Countermeasure Anti-Torpedo (CAT) and Acoustic Device Countermeasure (ADC MK2 Mod4). There are two development programs, the CAT program develops a canisterized Anti-Torpedo Torpedo (ATT) as an ACAT II program. The TWS develops the required torpedo detection, classification and localization (TDCL) ship systems as an ACAT III program. The AN/SLQ-25X solicitation was cancelled due to a more cost effective technical solution of interfacing the TWS to NIXIE system. The program will develop and field six Surface Ship Torpedo Defense prototype (TWS/CAT) Engineering Design Model (EDM) systems on CVNs. Each prototype consists of one TWS and eight CATs. The six systems were accelerated due to the lack of hard-kill 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. The program delivered one hybrid prototype system in FY13 on USS GHW BUSH. The next prototype is expected to deliver in FY14; This system will be delivered in a roll-on/roll-off (RO-RO) configuration and installed on USS Roosevelt. The program will build and deliver one additional RO-RO and one EDM in FY15 and 2 EDMs in FY16. The program will focus on first providing torpedo defense capability to High Value Units (HVU). The Initial Operational Capability (IOC) system will be installed on one CVN and one Combat Logistics Force (CLF) ship (both HVUs) with IOC in FY19.

Change Summary Explanation
Financial: FY 2013 reductions include sequestration and general reductions. FY 2015 includes increases for the SSTD Rapid Fielding Plan, speed-to-fleet technologies. FY 2015 also includes decrease due to the Department's decision to reduce contracted services and other rate/miscellaneous adjustments. Technical and Schedule: FY13 reductions and adjustments eliminated 1 of the 2 RO-ROs and delayed the remaining unit to the end of FY14. IOC is FY19. PB14 changed the requirement to deliver 2 EDMs in FY15 to 1 RO-RO and 1 EDM.
