 In May 2018 a former Marine officer, Jeff Groom, published an article concerning the Amphibious Combat Vehicle.Both BAE System's and SAIC's ACV 1.1 test vehicles could self-deploy and swim from a ship in contradiction to General Dunford's testimony in March 2015.However, there is apparently no longer a need for speed on water as both test vehicles move through the water at 7 knots using traditional water propellers, the same speed as the legacy 1970s AAV.
