Countermeasures modification

Raytheon and US Naval Sea Systems Command have finalised an $11 million modification to an existing contract for the company’s AN/AQS-20A mine hunting sonar systems. The modification brings the total value of the contract, originally awarded in September 2005, to $104.9 million.

Under the contract, Raytheon Integrated Defense Systems (IDS) will manufacture, test and deliver 11 AQS-20A sets and associated support equipment and engineering services. The contract also includes an option for 11 additional systems, services and support equipment for 2007.

AN/AQS-20A, a component of the Organic Mine Countermeasures family of systems, is the primary mine hunting system integrated into the US Navy’s MH-60S airborne mine countermeasures helicopters.

According to Raytheon, AN/AQS-20A enables the detection, classification and localisation of bottom, close-tethered and volume mines. It is also the primary mine hunting mission system for the Littoral Combat Ship Flight 0.

The AN/AQS-20A system is towed undersea to scan the water in front and to the sides of the vehicle as well as the sea bottom for anti-shipping mines. The system uses sonar and electro-optical sensors to provide high-resolution images of mines and mine-like objects and high-precision location information.

Work on the contract will be performed at Raytheon IDS’ MaritimeMissionCenter in Portsmouth, Rhode Island, Arete Associates in Tucson, Arizona, and Raytheon Technical Services Company in Norfolk, Virginia.
