The U.S. Navy’s Floor Ship Torpedo Protection (SSTD) program supplies a detect-to-engage layered torpedo protection functionality. The 4 main programs that comprise the U.S. SSTD are the SLQ-25 NIXIE system, the Torpedo Warning System (TWS), the Countermeasure Anti-Torpedo (CAT), and the Acoustic System Countermeasure (Floor ADC Mk 2). CAT and TWS are improvement applications.
The CAT program develops a canisterized anti-torpedo torpedo (ATT).
The TWS program develops the torpedo detection, classification and localization programs required to make use of CAT.
Collectively, the TWS and CAT programs make up the Anti-Torpedo Torpedo Protection System (ATTDS).
The U.S. Navy halted improvement of the ATTDS portion of the SSTD round September 2019 on account of poor efficiency and eliminated the prototypes from its plane carriers. Apparently, whereas the system did work in precept, it was not thought-about dependable sufficient for operational use.
The SLQ-25 NIXIE is a towed acoustic and non-acoustic countermeasure system. The SLQ-25 program develops countermeasure applied sciences and capabilities to enhance ship survivability towards future torpedo threats. The system has undergone a number of commercial-off-the-shelf (COTS)-based enhancements with all current SLQ-25(V)s now being upgraded to the newest SLQ-25E variant.
Moreover, this NIXIE expertise was used as a basis to construct the SLQ-61 Light-weight Tow (LWT) Torpedo Protection Mission Module (TDMM) for the Littoral Fight Ship in addition to different small fight vessels such because the Constellation class frigates.
With the submarine risk growing every day, the U.S. Navy is more likely to forge forward with SSTD improvement even when it has to revamp the whole authentic system idea. Maybe the U.S. Navy will observe the routine of a number of of the world’s different main navies and focus extra closely on expendable decoys and anti-torpedo torpedoes.
