FMC modified an LVT-2 in August 1943 by moving the engine forward and adding a large ramp door in the rear,[9] allowing troops to exit from the rear of the vehicle. Capacity went from 16 in the LVT-2 to 30 making earlier LVTs largely obsolete. This innovation also greatly facilitated the loading and unloading of cargo. Some vehicles received armor kits. It was by far the most numerous version of the LVT, with 8,351 units delivered. US Army received 6,083 and British Army 500. Many of the British LVT versions were armed with a 20 mm Polsten cannon and 2 × .30 in (7.62 mm) Browning machine guns.
Since no major changes were made to the engine and transmission of the LVT-2 the LVT-4 was completed much quicker than the LVT-3, with the first machines going into action at Saipan in June 1944.
