AN/SQQ-89 Surf ASW Combat System

AN/SQQ-89 Surf ASW Combat System aims to enhance the Navy's anti-submarine warfare (ASW) capabilities in response to evolving submarine technologies and increasing submarine threats. The program focuses on providing integrated undersea warfare combat management, fire control, command and control, and on-board training to enable surface combatants to engage USW targets in both open ocean and littoral environments. The specific objectives include upgrading the AN/SQQ-89A(V)15 system to decrease ship vulnerability to torpedo attacks, improve surface ship USW lethality, and mitigate Commercial-Off-The-Shelf (COTS) obsolescence and supportability issues. Additionally, the program aims to procure upgraded software/hardware technology for all DDG51 Class surface combatant platforms with a previously fielded AN/SQQ-89A(V)15 through the Technology Insertion/Refresh program. The program also includes recurring engineering support services associated with AN/SQQ-89A(V)15 Surface Ship ASW Combat System equipment at the Surface Combatant Systems Center (SCSC) Wallops Island, VA test facility to support land-based testing, external interface testing, and AEGIS Integration Event (AIE) production systems testing for interoperability risk reduction analysis purposes as necessary to certify that each incremental AN/SQQ-89A(V)15 hardware/software build is compatible with multiple AEGIS Weapons System (AWS) baselines prior to installation.

The program addresses the need for effective offensive engagement range against adversary submarines, which are expected to match or outrange individual U.S. and multinational platform sensors and weapons in many tactical environments. It also emphasizes the importance of countering adversarial anti-access and area denial strategies by ensuring ASW forces are effective in all operating environments, ranging from the deep open ocean to the littorals. The program's detailed description outlines specific efforts such as hardware buys, installations, test events, and technology insertion/refresh initiatives aimed at enhancing ASW capabilities against modern diesel and state-of-the-art nuclear submarines. Additionally, it highlights the importance of establishing a stable technology refresh program to ensure critical Undersea Warfare capability while reducing Total Ownership Cost (TOC) to the Navy.
