The new Amphibious Combat Vehicle (ACV) that was revealed at the Modern Day Marine trade show in Quantico, is able to effortlessly move on land, as well as in the water.
This vehicle weighs approximately 20 tons (18,100 kilograms), has eight wheels, and its engine is a six-cylinder turbodiesel.
Lockheed Martin, an American security and defence company, was the one that made the Amphibious Combat Vehicle. The purpose of the new vehicle is to replace the almost 40-year-old swimming tanks of the U.S. Marine Corps.
Marines normally use these types of vehicles in order to move safely in the water and on land.
Because they function in different environments, the amphibious vehicles are not very easy to deigns and build, said David Hunn, a technical director of the Amphibious Combat Vehicle project.
“For military amphibians, you don’t have the benefit of swimming in calm lakes or canal ways and then driving on smooth roads,” Hunn stated.
When building the tank, the first thing that engineers must do is to figure out a way to make the 20-ton vehicle float. The water would have to be more dense than the Amphibious Combat Vehicle, in order for the tank to float. That happens when the the Amphibious Combat Vehicle displaces a volume of water that is heavier that the tank itself.
Another thing that the engineers have to do it to make sure that the tanks is impermeable. They also have to make the tanks resistant to enemy attacks. The Amphibious Combat Vehicle has only one door, and one window, because it is essential to keep the water from entering the tank. The vehicle’s body is both hydrodynamic (it floats) and resistant to blasts.
The new vehicle can automatically turn from tank to ‘boat’ using a computer system. People had to operate the previous amphibious vehicles manually when they wanted to go from land into the water and vice versa.
Thanks to its powerful engine, the Amphibious Combat Vehicle can reach up to 60 miles (96 kilometres) per hour on land. In the water it reaches speeds up to 5 knots (9.26 kilometres per hour).
The Lockheed Martin Company stated that the new Amphibious Combat Vehicles may also be used in rescue missions, not just in combat.
