Landing Vehicle, Tracked, Mark 3.

Compared to the LVT2 and LVT4, the LVT3's driver was placed close to the vehicle's bow, which improved visibility. Applique armor has been mounted on the lower surface of the cab front on this machine. The tracks of the LVT3 are double-pin and rubber bushed, in contrast to those found on the earlier types of amphibians.

Landing Vehicle, Tracked, Mark 3 in Inchon, South Korea.

Applique armor has been installed on both on the upper and lower portions of the cab front on this vehicle. The central cab window is open, and the vision blocks and bow machine gun mount take advantage of the front windows visible in the vehicle above. (Picture taken 14 Sep 1950; available from the National Archives.)

Landing Vehicle, Tracked, Mark 3C.

The covered cargo compartment was the most significant change on the LVT3C. The rear ramp is down on this vehicle, and the covers for the cargo compartment are folded open. The new open crew hatches somewhat shroud the machine gun turret on the cab roof, but the extension to the bow is obvious when compared with the vehicle above. Note how the top deck is sloped towards the rear to ease departure from landing ships. (Picture from Research, Investigation and Experimentation in the Field of Amphibian Vehicles.)

Landing Vehicle, Tracked, Mark 3C in Galesburg, Illinois.

A better view of the machine gun turret is provided in this snowy image. A vision block was installed on each side, and a periscope and ventilator dome could be found on its roof. The bow machine gun is represented on this vehicle as well. (Picture courtesy Warren Kuntz.)

Compared to the earlier vehicles, the armor added to the sides can also be seen. The vision blocks for the drivers are apparently missing from this machine. (Picture courtesy Warren Kuntz.)

Landing Vehicle, Tracked, Mark 3.

An exploded view of the inner surface of the vehicle's track is shown here. In contrast to earlier amphibians, LVT3 ran on a double-pin rubber-bushed track similar to that found on light and medium tanks. The track blocks were hollow steel, and the 2.75"- (6.99cm-) high cleat was welded to the outer face of each track block. The rubber bushings provided better wear characteristics against sand and salt water than the previous tracks' many bearings.
