Design

The craft can carry a maximum load of 55 tons, land on hostile beaches doing 40 knots and it can climb at up to 6 degrees. They have 12.7 mm machine guns for self defense. The crew cockpit carries three crew and a landing-force commander. The LCAC can carry, in addition to troops, a main battle tank or two amphibious assault vehicles. So far four of these units have been delivered, and more are likely to be ordered. It has been offered for export to foreign navies.^[1]
