Surface Ship Torpedo Defense
Abstract
The Surface Ship Torpedo Defense (SSTD) program provides a detect-to-engage layered torpedo defense capability. The funding supports mission readiness for Anti-Torpedo Torpedo Defense System (ATTDS) equipped ships and the sundown effort of ATTDS. The sundown of ATTDS returns the platform back to its original NIXIE configuration during a scheduled availability. In FY21, funding supports four (4) CVNs during their deployment cycles prior to CVN system sundown. 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 CAT program develops a canisterized Anti-Torpedo Torpedo (ATT). The TWS program develops the required torpedo detection, classification and localization (TDCL) ship systems to employ CAT. 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. Starting in FY20, the ATTDS Program commenced sundown effort to return the five CVNs to their original configuration. The AN/SLQ-25 (NIXIE) is a towed acoustic and non-acoustic countermeasure system. The AN/SLQ-25 program develops countermeasure technologies and capabilities to improve ship survivability against future torpedo threats. Research and development 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 hardware and software in representative acoustic environments, against projected threats using both digital and hardware-in-the-loop simulations. Incorporation of the technology into the appropriate product line upon successful evaluation. line.
