LVTs was SHPX ORER help needed

LVTs make excellent steam era freight car loads. In HO scale, the LVT(a)-4 and LVT-4 are produced by Artitec. Here are one each, test loaded on a P2K flat car. What is interesting to me is the sheer size of these vehicles compared to the Sherman tank, for example.

Minor point …

The LVT4 had no significant gun nor armor. It was an open-top troop transport vehicle, with a stern ramp.

The first successful LVT was the LVT1 that was a militarized version of an amphibious swamp buggy, the “Alligator”. The LVT1 completely changed amphibious assaults, but as a military vehicle it left a LOT to be desired. Among other problems, it had no stern ramp (Marines had to jump over the side to get out). It was soon followed by a much improved version, the LVT2 which also lacked a stern ramp.

The came the LVT4 which did include a stern ramp making for safer and faster exit.

The need for firepower resulted in the so called “Amtanks” with gun turrets and some (not much) armor. First were the LVTA-1 (37mm gun), and later  LVTA-4 (75mm short barreled howitzer).

All these types saw considerable service in the pacific invasions. The later LVT4 and LVTA-4 were mainly used at Iwo Jima and Okinawa.

They float, so they need the internal volume to displace the water.

Compare to the Duplex drive Sherman with the folding canvas screens.

The weight of US WWII combat vehicles was limited by the capacity of the ship cranes, about 20 tons.

This is one of the reasons the US did not field a heavy tank, they did not  have a way to transport them.

WWII M4 “Sherman” tanks weighed from 28-41 tons (many versions & variations). The WWII T26 (later became the M26 “Pershing”) weighed about 45 tons.

For comparison the LVTA-4 weighed only about 18 tons. As noted that HAVE to be light enough to float. That means minimal armor and large volume. The unarmored troop transport versions would be in the 12 ton weight range.

Even the “armored” LVT versions provided only partial protection from small arms fire. They were extremely vulnerable to even the lightest anti-tank guns (unfortunately the Japanese had some very good anti-tank weapons).

The LVTA-4 used the same turret as the M8 Howitzer Motor Carriage, which was based on the M5 light tank chassis. Compared to a LVTA-4 it weighed about the same, but was both much smaller and more “dense” having much heavier armor (and would NOT float … it would sink like a rock).
