Navy asks CCC to provide important components for sonar transducer aboard surface warships

CRANE, Ind. – U.S. Navy anti-submarine warfare (ASW) experts are looking to Canadian Commercial Corp. (CCC) in Ottawa to build and refurbish important components for the Navy's AN/SQS-53 hull-mounted sonar array on surface warships.

CRANE, Ind. – U.S. Navy anti-submarine warfare (ASW) experts are looking to Canadian Commercial Corp. (CCC) in Ottawa to build and refurbish important components for the Navy's AN/SQS-53 hull-mounted sonar array on surface warships.

Officials of the Naval Surface Warfare Center in Crane, Ind., announced a $10 million contract to CCC Wednesday to build and refurbish the TR-343 transducer tube assemblies as part of the repair of TR-343 sonar transducers.

The tube assembly is the housing used for the TR-343 transducer, as part of the AN/SQS-53C hull mounted sonar array subsystem, AN/SQQ-89(V) anti-submarine warfare (ASW) System. CCC acts as Canada’s international contracting and procurement agency.

The AN/SQS-53 hull mounted sonar array is a large bulb-like structure built into the bows below the water line of U.S. Navy Arleigh Burke-class destroyers, Ticonderoga-class cruisers, and Japanese navy Kongo-class destroyers. The AN/SQS-53 is a component of AN/SQQ-89(V) acoustic sonar weapons system for surface warships.

The AN/SQQ-89(V) is an integrated surface ship undersea warfare combat system with the capability to search, detect, classify, localize, and attack enemy submarines.

The surface ship AN/SQS-53 is a computer-controlled surface-ship sonar that has active and passive operating capabilities providing precise information for ASW weapons control and guidance.

The AN/SQS-53C, the latest version of this hull-mounted sonar system, retains the transducer assembly from either the AN/SQS-53A and 53B, yet provides greater range and detection capability with only half of the electronics footprint and less weight than earlier versions.

Constructed in standard electronic modules, the AN/SQS-53C is an all-digital system that provides apparent range, bearing, and true bearing of submarine contacts with active sonar and true bearing of contacts with passive sonar.

Active sonar transmits a ping to bounce sound waves off the hulls of submarines. Passive sonar means simply listening for the sounds of submarines and surface vessels. This system is the basic sonar watch-standers tool to keep an eye on all ship traffic; the system often detects other surface ships at greater ranges than can most radar systems.

The AN/SQS-53 simultaneously can detect, identify, and track several different targets, and interfaces with the host vessel's digital computers. It has three active modes of operation: surface duet, bottom bounce, and convergence zone. It also can ping off buoys to pinpoint its own location in foreign ports.
