SURTASS

SURTASS is a critical component of the Navy's undersea surveillance capability, providing deep ocean and littoral acoustic detection and cueing for tactical weapon platforms against diesel and nuclear submarines as well as surface vessels in any given Area of Operations worldwide. The program involves the operation of five Small Waterplane Area Twin Hull (SWATH) T-AGOS ships in the Pacific area, each configured with different capabilities to support passive and active operations. Additionally, the program includes two shore sites equipped with processing and display suites to receive acoustic data via satellite communication links. The program also encompasses a cost-sharing agreement with Japan to provide similar capabilities for the Western Pacific region. Furthermore, the Expeditionary Surveillance Towed Array Sensor System (SURTASS-E) provides a passive capability packaged for mobilization on Vessels of Opportunity (VOOs) as part of a Rapid Prototyping, Experimentation, and Demonstration (RPED) project.

The FY24 funding amount of $33.910M for Program 2237 includes funding for various components such as Integrated Common Processor (ICP) units, TL-29A towed array refurbishments, Surveillance Towed Array Sensor System (SURTASS) Team Trainer (STT) procurements, field changes and modifications for multi-year transition to an upgraded command and control (C2) system, and cost sharing associated with Japanese Auxiliary Ocean Surveillance (J-AOS) ships and shore sites ICP hardware technology refresh. The ICP system hardware and software configuration varies from ship to ship depending upon the type of arrays installed on each platform. The procurement and installation costs will vary from year to year based on factors such as end-of-life component refresh requirements, cyber security improvements, testing needs, and updates to Configuration Control Models (CCMs) or Engineering Measurements Program (EMP) systems for each major hardware refresh.
