SURTASS

The Surveillance Towed Array Sensor System (SURTASS) is a vital part of the Navy's undersea surveillance capabilities, designed to improve acoustic detection and cueing for tactical weapon platforms. Its main goal is to provide deep ocean and littoral acoustic detection against diesel and nuclear submarines, as well as surface vessels. This system is deployed on dedicated Anti-Submarine Warfare (ASW) T-AGOS ships that tow long acoustic arrays, collecting data that is relayed to shore facilities via satellite for processing. Currently, the program operates five Small Waterplane Area Twin Hull (SWATH) Passive/Active T-AGOS ships in the Pacific area, each equipped with advanced signal processing systems.

The Integrated Common Processor (ICP) plays a crucial role within the SURTASS program by providing signal processing and display capabilities. The configuration of the ICP system varies based on the type of arrays installed on each platform, whether passive only or combined with Low Frequency Active (LFA) or Compact Low Frequency Active (CLFA) capabilities. The objectives for the ICP include addressing end-of-life component refreshes, enhancing cybersecurity measures, and ensuring compatibility with updated hardware configurations. These efforts are essential for maintaining operational effectiveness and adapting to evolving technological requirements.

A significant aspect of the SURTASS program is the TL-29A Twinline Arrays, which are designed for increased surveillance capability in high clutter environments and littoral areas. These arrays consist of shorter lengths and support equipment tailored for shallow water operations. The program focuses on refurbishing existing array legs and associated support equipment annually to ensure continued functionality and readiness for deployment. This refurbishment process includes ancillary test sets and control systems necessary for effective array operation.

The SURTASS Team Trainer (STT) provides high-fidelity training capabilities for crews during Home Port Training Periods and Pre-Deployment Certification Periods. This training ensures that personnel are well-prepared to operate the sophisticated systems aboard T-AGOS ships effectively. Field Changes/Modifications within the program address deficiencies identified through fleet use, facilitating transitions to upgraded command and control systems like the Consolidated Afloat Network Enterprise System (CANES). These modifications ensure that aging systems are replaced to maintain continuity of operations in various scenarios.

The Japanese Auxiliary Oceanographic Surveillance (J-AOS) component involves cost-sharing agreements with Japan to enhance regional surveillance capabilities in the Western Pacific. This collaboration includes procuring Towed Arrays for new J-AOS ships and refreshing Integrated Common Processor hardware at shore sites. Such international partnerships aim to bolster collective maritime security efforts while sharing technological advancements across allied forces.
