The first production model of the LVT was the LVT-1 and it descended from the earlier Roebling Aligator. It had no armor and it could have two .30 MGs mounted, plus two .50 MGs mounted as well. It also had a crew of 3 and it was powered by a 143 hp, water cooled, WXLC-3 gasoline engine. The LVT-1s weight was about 32,000 pounds and it could carry an additional 24 marines. The length is about 21' 6" and the height is about 8 feet. It also had a top speed of 12 mph on land and 6 mph in water. The transmission had 3 forward speeds and 1 reverse and it had a fuel capacity of about 80 gallons. The LVT-1 also had a hard time riding on land and had sometimes broken down.
The LVT-2 was the successor of the earlier LVT-1 and had several modifications including a new transmission and the new Continental W-670-9A engine. The LVT-2 also had a top speed of 32 km/h. It had a weight of about 13,600 kilograms and like the older model it was unarmored. This would change with the coming of the LVT-A2; this new system would incorporate 63mm of armor in the sides of the hull and about 12mm of armor for the cabin.
The LVT-A2 was also slightly heavier than the LVT-2 and it had a 5 speed forward, 1 speed reverse transmission. This was also just the same as the LVT-2. The LVT-A1 was nothing at all like the previous 3 models. It had a 37mm main gun and it was an amphibious tank. It could also have 4 MGs mounted and it was designed to provide fire support for marines landing on enemy beaches.
The LVT-A1's design was based on that of the LVT-2 and it had the cannon design of the M3 Stuart. The LVT-3 was designed to be able to carry jeeps and other supplies. It could also carry around 30 marines and itwas first used at the Battle of Okinawa. The LVT-3 had a weight of about 38,000 pounds and it had a top speed on land of about 17 mph. It was produced by the Borg Warner Corporation just like the LVT-4.
The LVT-4 had many concepts from the LVT-3 such as the engine moved forward allowing for more capacity and it also had a rear ramp. The LVT-4 had a crew 3 and it could carry around 30 passengers. It also had the same engine as most of the previous models which is the Continental W-670-9A engine. It had a top speed on land of about 20 mph and it had a top speed in water of about 7.5 mph. The final version of the LVT which was used during WWII is the LVT-A4. The LVT-A4 was again an amphibious tank and it had the 75mm M3 main gun. It also had around 1 inch of armor in most of the tank. The LVT-A4 had a top speed of about 25 mph on land and about 7 mph in water.
LVTs were used in many different battles and on several fronts. Theses included the Pacific Theater and European Theater. LVTs proved their importance in the Pacific Theater on Tarawa. LVTs were able to pass the large coral reef surrounding Tarawa while LCVPs got stuck. The LVT-A4 was first used on Saipan and some LVTs were even used by Great Britain via Lend Lease. An example of this is the LVt-4 which is designated the LVT(f) and it was modified to have 2 flamethrowers. Although LVTs were used in Europe, they were mainly used in the Pacific Theater in island hopping campaigns.
