The system employs an open architecture business model using state-of-the-art commercial computing technology to achieve major performance gains over previous designs, at reduced cost. The U.S. Navy's goal is to achieve a single, common configuration to reduce system life cycle costs while allowing for rapid war fighting improvements.

The AN/SQQ-89A(V)15 is the U.S. Navy surface force's undersea warfare combat system and is installed on all of the Navy's Aegis-equipped cruisers and destroyers. Using a variety of underwater sensors, the system detects, classifies and localizes submarines and other undersea threats.

It includes a hull-mounted sonar, towed array, a sonobuoy processing system and a fire-control system used to launch weapons against undersea targets, all integrated with the Lockheed Martin-produced Aegis Combat System.

"The AN/SQQ-89A(V)15 is the U.S. Navy surface force's premier Anti-Submarine Warfare System," said Denise Saiki, Lockheed Martin's Undersea Systems business vice president and general manager . "Working closely with the Navy, we have led the system design team, and have been delivering, modernizing and supporting the SQQ-89 system for more than 25 years. Its capability is second to none."
