CRANE, Ind. – U.S. Navy anti-submarine warfare (ASW) experts needed a company to build important components in support of the Navy PMS-401 Submarine Acoustic Systems Program Office. They found their solution from SyQwest Inc. in Cranston, R.I.
Officials of the Naval Surface Warfare Center in Crane, Ind., announced a $10 million contract to SyQwest Wednesday to build TR-343 sonar transducer ceramic stack assemblies for the Navy Submarine Acoustic Systems Program Office at the Pentagon.
The TR-343 transducer is part of the AN/SQS-53C hull mounted sonar array subsystem, AN/SQQ-89(V) anti-submarine warfare (ASW) system. The AN/SQS-53 is a component of AN/SQQ-89(V) acoustic sonar weapons system for surface warships.
SyQwest Inc. manufactures and tests transducer ceramic stack assemblies for the TR-343 transducer which is used on U.S. Navy surface ships. The TR-343 transducers are part of the AN/SQS-53 Hull Mounted Sonar Array Assembly which is a component of AN/SQQ-89(V) acoustic sonar weapons (ASW) system.
The AN/SQQ-89(V) is an integrated surface ship undersea warfare (USW) combat system with the capability to search, detect, classify, localize, and attack submarine targets. The ceramic stack assembly provides the required piezoelectric characteristics to produce mechanical motion in the water for generating sonar signals when a large voltage is applied.
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. This contract includes foreign military sales.
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.
