AN/SQQ-89

The AN/SQQ-89 Undersea Warfare Combat System is a naval anti-submarine warfare system for surface warships. The system presents an integrated picture of the tactical situation by receiving, combining and processing active and passive sensor data from the hull-mounted array, towed array and sonobuoys. AN/SQQ-89 is integrated with the AEGIS combat system and provides a full range of USW functions including active and passive sensors, underwater fire control, onboard trainer and highly-evolved display subsystem. It provides detection, classification, and targeting capability to the following platforms:


 * Oliver Hazard Perry class frigate (FFG-7)
 * Spruance class destroyer (DD-963)
 * Ticonderoga class cruiser (CG-47)
 * Arleigh Burke Class destroyer (DDG-51)

The ASW system combines inputs from active and passive hull mounted sonars, tactical towed arrays, and sonobuoys.

The SQQ-89 system was developed by Lockheed Martin for the United States Navy.
