Re: LVTs was SHPX ORER help needed

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).

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.
