On 15 September 2005, Raytheon was awarded a not-to-exceed $55 million contract for the low rate initial production (LRIP) of the AN/AQS-20A sonar/mine detecting set. The contract was set to expire by March 2010. The US Navy intends to provide support to Carrier strike groups and expeditionary strike groups deploying the AQS-20 on the MH-60S helicopter and the Littoral Combat Ship (LCS). This contract was amended in August 2006 by Naval Sea Systems Command. The final contract covered production of 11 AQS-20A sonars worth $105 million and further 11 as option as well as support equipment and services for 2007. On 12 April 2006 Raytheon was awarded a $38.6 million contract from Naval Sea Systems Command for five AN/AQS-20A mine hunting sonar systems. On November 28, 2007, Raytheon was awarded a $52 million contract for the low rate initial production of nine AN/AQS-20A sonar mine detecting sets, spares and their accompanying kits.

The US Navy AN/AQS-20C is a minehunting sonar developed for integration onto the Littoral Combat Ship (LCS) and the Mine CounterMeasure (MCM) Unmanned Surface Vessel (USV). The AN/AQS-20C comprises five distinct sonars, including synthetic aperture sonar that provides the highest possible resolution for acoustic identification. The system detects, classifies, localizes, and identifies mines on the seabed, near-bottom moored mines, volume mines, and near-surface mines. The AQS-20C towed sonar system completed development testing in February 2019 and is expected to achieve initial operational capability (IOC) in early 2020.
