In February 2016, the Navy announced they were halting procurement of the RMMV due to reliability issues, with the existing ten RMMVs to be upgraded to increase reliability. The upgraded RMMVs will be fielded in 2018, and testing will be conducted to see if the Fleet class common unmanned surface vessel (CUSV) can tow the AQS-20A, and if successful will be used for minehunting by 2020. If the Knifefish UUV can have its endurance increased, the vessel will take over the mission from both systems.
