Surface Ship Torpedo Defense

Abstract

The Surface Ship Torpedo Defense (SSTD) program provides a detect-to-engage layered torpedo defense capability. The four (4) major efforts that comprise SSTD are the AN/SLQ-25 (NIXIE) system, Torpedo Warning System (TWS), the Countermeasure Anti-Torpedo (CAT), and Acoustic Device Countermeasure (Surface ADC MK2). The ATTDS provides a hard kill torpedo defensive capability on High Value Units (HVU's). The SSTD program has developed and fielded five (5) ATTDS Engineering Design Models (EDMs) systems on CVNs. Each EDM system is one (1) TWS with a load out of a maximum of eight (8) CATs. In FY20, the ATTDS Program commenced sundown efforts to return the five (5) CVNs to their original configuration. Two (2) system removals completed in FY22, with one (1) more scheduled for FY23. FY23 and FY24 funding will provide minimal support to the 2 remaining CVN installations with system preservation the primary focus. Research and development in torpedo defense of new technologies and capabilities developed under the Future Naval Capabilities (FNC), Small Business and Innovative Research (SBIR), and other Research, Development, Test & Evaluation (RDT&E) initiatives are evaluated to determine their effectiveness and impact on improving ship survivability. Evaluations of new and emerging torpedo defense hardware and software in representative acoustic environments, against projected threats using both digital and hardware-in-the-loop simulations is performed. The AN/SLQ-25 (NIXIE) program has built an ECP package for technical refresh designated as the AN/SLQ-25E. This ECP is a form-fit-function replacement of the AN/ SLQ-25C, which is widely fielded across the surface fleet. The AN/SLQ-25E is more modular, maintainable, and will meet all current and future cybersecurity requirements. The modular and Commercial-Off-The-Shelf (COTS) design of AN/SLQ-25E will allow for future capability growth to outpace the threat in torpedo defense. Two (2) FY22 Congressional adds support research and development of new torpedo defense capabilities specifically on the 25E effort, as well as improve the safety and reliability of the 25E towed winch and reel system.

Change Summary Explanation
FY2022 SBIR reduction of $0.289 million. FY2024 program increase by $0.730 million to support functionality of TWS prior to schedule DEMIL on two (2) CVN platforms. Changes to the program's schedule (R-4 and R-4A) beginning in FY2023, reflect the addition of funding to support program requirements across the FYDP.
