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). FY22 funding supports mission readiness for Anti-Torpedo Torpedo Defense System (ATTDS) equipped CVNs. The CAT program developed a canisterized Anti-Torpedo Torpedo (ATT). The TWS and CAT systems make-up the ATTDS. The ATTDS provides a hard kill torpedo defensive capability on High Value Units (HVU's). The program has developed and fielded five ATTDS Engineering Design Model (EDM) systems on CVNs. Each EDM system is one TWS with a load out of a maximum of eight CATs. In FY20, the ATTDS Program commenced sundown efforts to return the five CVNs to their original configuration. Removal of two systems will complete in FY22. FY22 and FY23 will provide minimal support to the 3 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. In FY22, there is no development or evaluation of new or existing torpedo defense capabilities.
