Raytheon awarded contract action for AN/AQS-20 design efforts

Raytheon is being awarded a cost-plus-fixed-fee undefinitzed contract under delivery order under a previously awarded indefinite-delivery/indefinite-quantity contract (IDIQ) for design efforts and long lead material procurement for deploy and retrieve systems in support of the AN/AQS-20 Minehunting program.

The $9.6 million contract was awarded by U.S. Navy’s Naval Sea Systems Command (NAVSEA) base in Washington, DC.

The highly specialized equipment will deploy, tow, and retrieve the AN/AQS-20 sonar in support of minehunting operations.  This system is in support of the Littoral Combat Ship Mine Countermeasures Mission Package test schedule.

Work will be performed in Portsmouth, Rhode Island (81 percent); and Keyport, Washington (19 percent), and is expected to be completed by November 2018.


The AN/AQS-20 is an advanced minehunting sonar system that has been designated as the minehunting sonar for the Littoral Combat Ship’s (LCS) mine countermeasure mission package.

The system incorporates five separate sonars in a compact, lightweight and hydro-dynamically stable towed body.

It uses state-of-the-art imaging sonars, signal processing and computer algorithms to provide real-time, computer-aided detection and classification against the full spectrum of threat mines.

The system automatically localizes mine-like objects and provides the operator with a visual image and a contact data list. All mission data is recorded for post-mission analysis.

The AN/AQS-20 has been extensively tested and operated from unmanned, underwater vehicles such as the AN/WLD-1 and is the only minehunting sonar sensor developed, tested and certified for Remote Multi Mission Vehicle (RMMV) deployment.
