The USN and Royal Australian Navy (RAN) will received upgraded hardware to support development, integration, manufacture, production, and testing of the AN/SQQ-89A(V)15 anti-submarine warfare (ASW) combat system suite, the DoD announced on 9 May.

AN/SQQ-89A(V)15 uses passive sonar to provide early warning of threat torpedoes. The open-architecture system requires software upgrades every two years and TI hardware upgrades every four years.
