LVT(4) Produced in Greater Numbers than Other LVTs

LVT(4) was produced in greater numbers than any other type of amtrac during World War II, which amounted to almost half of all LVT production.


Forward Engine, LVT(4)

The LVT(2) and LVT(4) had the same cargo space width, but the LVT(4) was longer. With the engine moved forward, the cargo area was located to the stern, which was accessible by a rear ramp, allowing cargo to be easily loaded and unloaded, including wheeled equipment.


Wash Vanes on the LVT(4)

In the photo above, note the wash vanes (the honeycombed boxes just above the tracks) which directed the water being pushed by the grousers so that it flowed out the back of the amtrac, rather than spraying up in the air.

LVT(4) Produced Late in the War

Production started on the LVT(4) during December 1943 and it entered service in time for the Battle for Saipan in June 1944. However, its development and production happened so late in the war that it could not be widely used until 1945.1


LVT(4) First Ramped Amtrac

The LVT(3) (Borg-Warner) and LVT(4) (Food Machinery Corporation), were being developed concurrently, however, production delays with the LVT(3) caused the LVT(4) to be the first ramped LVT to see action. This also causing the LVT numbering to appear out of sequence. 2

Armored version, LVT(A)4

An armored version, the LVT(A)4 was also produced, using the turret from the M8 75mm Howitzer Motor Carriage and deleting two machine gun positions. It was not evident at this time that the removal of these machine gun positions would be one of the most serious tactical shortcomings of the new LVT(A)4. 3 A total of 8,348 LVT 4s, and 1,890 LVT(A)4s were built. 4


LVT(4) participated in the following major campaigns during World War II: Saipan, Guam, Tinian, and Iwo Jima.
