By
December 2012, the Navy had ordered eight Knifefish units, at a total cost of US$ 20 million. In April 2013, General Dynamics completed its critical design review of the Knifefish, and began developing software and hardware for the operational version of the robot. The Knifefish was scheduled to

for fielding in 2020. For certain mine countermeasure missions, the
Knifefish is superior to the RMMV, but it doesn't have the endurance to cover large minefields; if endurance can be enhanced, the MCM package would be simplified, as the sensor is embedded in the vehicle rather than towed, and the

The Navy is considering increasing the endurance of the
Knifefish to take over minehunting in addition to searching for buried and high-clutter mines. Due to reliability issues with the Remote Multimission Vehicle (RMMV), only 10 will be upgraded and fielded in 2018. The Navy is also pursuing

Knifefish can then mark detected mines and record their locations in its database; the robot later uploads the data to its parent LCS, which destroys the mines. The Knifefish may be modified to transmit its data in real-time, if the Navy considers such a capability

Knifefish UUVs, which will scan the seabed near the ship and reduce the risk of mine damage to the LCS itself.
