LVT3 can be differentiated from LVT2 and LVT4 by its cab, which was nearer the bow on LVT3. LVT3's cab had three windows, like that of LVT1. LVT3 also had a rear loading ramp, since its engines were mounted in either sponson. Applique armor could be added to LVT3, which decreased its 9000lb (4000kg) cargo capacity by 2900lbs (1300kg). The engines and transmissions of LVT3 were the same as the light tank M5 Stuart's. LVT3 was known as Bushmaster.

Beginning in 1949, 1200 LVT3s were converted to LVT3(C) standard by the Long Beach Naval Shipyard. This involved mounting a .30cal MG in a turret on the vehicle roof and placing another .30cal MG in a ball mount in the cab right bow. A split aluminum cargo cover was installed which could be folded out of the way to on top of either sponson, escape hatches were fitted, and armor was added to the vehicles' sides. The bow of the LVT3(C) was extended to improve buoyancy. The LVT3(C) weight about 6000lbs (2700kg) more than LVT3.
