Surface Ship Torpedo Defense

Abstract

The Surface Ship Torpedo Defense (SSTD) program provides a detect-to-engage layered torpedo defense capability. The four 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). CAT and TWS are development programs. The CAT program develops a canisterized Anti-Torpedo Torpedo (ATT). The TWS program develops the required torpedo detection, classification and localization (TDCL) ship systems. The TWS and CAT systems make up the Anti-Torpedo Torpedo Defense System (ATTDS). 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. The program has developed and fielded five ATTDS Engineering Design Model (EDM) systems on CVNs. Each EDM system is one TWS with a CAT load out of a maximum of eight CATs. The systems were accelerated due to the lack of hard-kill torpedo defense on High Value Units (HVUs). The systems provide a hard-kill torpedo defense capability. The program delivered one hybrid prototype system in FY13 on USS GEORGE HW BUSH. The next prototype was delivered in FY14; this system was delivered in a roll-on/roll-off (RORO) configuration and installed on USS THEODORE ROOSEVELT. The next two installs were one additional RORO (USS EISENHOWER) and one EDM (USS HARRY S TRUMAN) in FY15. The fifth system was purchased in FY16 and has been installed on the USS NIMITZ. Both Roll-On/Roll-Off systems will be installed on the same CVN's as EDM Systems starting in FY17 and completed by the end of FY18. Overall, the ATTDS program will continue SALVO EDM Development through FY17. Two independent testing events are planned in 1Q FY18. A Contractor Test (CT-5) is planned and a Quick Reaction Assessment (QRA) is planned for the same at sea event. The QRA is paramount to the program to gain approval to deploy the system with a SALVO Capability and then sustain the existing five CVN installed systems during FY18-FY22. Throughout the period of FY18-FY22, no program of record acquisition milestones will be pursued. Software upgrades, material engineering changes, and safety certifications will remain the program's top priorities to ensure the highest operational availability and performance of the deployed CVN systems.
