United States' Landing Vehicle Tracked, LVT-3, "Bushmaster"

Design

The LVT-3 was a new design.1

Crew

In front of the cargo area was located a cab for the driver and co-driver.1 The gunner had a step right behind them.1

The driver had a wooden box in the cab that contained wooden plugs and other materials to plug holes that were caused by enemy gun fire.1

Sponsons

There were two Cadillac engines that were each located in a sponson on the sides.1 The transmissions, bilge pumps, and blowers were also placed in the sponsons.1

Cargo Area

By having the engines in the sponsons this allowed for more cargo area.1

There was a ramp located at the rear and it was hand operated.1 The ramp had a rubber seal around it to keep the water from entering.1

There was a grating that made up the deck that allowed any water that entered to drain and then the bilge pumps would remove it.1

Armor

Additional armor could be added to the LVT-3's crew area.1

Tracks

The tracks were rubber bushed and made narrower.1

Production

  • LVT-3: 2,6921
