The US Naval Air Systems Command has awarded Raytheon a $16.5 million contract for low-rate initial production of four antisubmarine AN/AQS-22 dipping sonars.
The AN/AQS-22 will be used by the new Sikorsky/ Lockheed Martin produced MH-60R helicopter for undersea warfare missions including submarine detection, tracking, localisation and classification.
The system successfully completed stand-alone operational testing in 1999, and the AN/AQS-22 has been extensively operated with the MH-60R during development testing. During recent tests, the system was successfully exercised in shallow and deepwater flights.
Under the contract, Raytheon, as prime contractor, will provide systems integration as well as the sonar transmitter and receiver. Industry partner Thales Underwater Systems will provide the outboard array and reeling equipment.
The contract also includes associated engineering, testing and program management services.
Deliveries are expected to be complete by October 2004. The MH-60R is expected to enter US Navy service in 2005.
