SSTD

Surface Ship Torpedo Defense (SSTD) is a Navy initiative aimed at providing a layered torpedo defense capability to protect surface ships. The program focuses on the AN/SLQ-25 (NIXIE) system, which is the primary SSTD system for the Navy, offering towed persistent torpedo countermeasure capability to safeguard over 180 surface ships. The funding for FY24 will support the completion of hardware and software integration, system testing, and the incorporation of any design changes identified during testing. Additionally, it will address engineering changes for AN/SLQ-25C and earlier variants, continuation of the system technical insertion resulting in the new configuration baseline (AN/SLQ-25E), and obsolescence issues to extend the military service life of the system.

The specific objectives of Program 2213 include addressing recurring engineering changes for AN/SLQ-25C and earlier variants, continuing the system technical insertion to establish the new configuration baseline (AN/SLQ-25E), and resolving obsolescence issues related to hardware and software configuration changes. These efforts are crucial for maintaining operational readiness and extending the military service life of the AN/SLQ-25 NIXIE system. The program aims to ensure that over 180 surface ships are equipped with an effective torpedo defense capability through ongoing updates and maintenance activities.
