At full capacity, the UHAC should be able to carry three main battle tanks ashore from a range of 200 nautical miles.

Altogether, the UHAC can carry payloads up to 190 tons, almost three times as much as the LCAC.

Unlike the LCAC, the UHAC can continue moving while onshore across mud flats, tidal marsh areas, and even over sea walls of up to 10 feet in height.

This movement is due to the UHAC's treads, which are composed of low pressure captive air cells held within foam casings.

But the vehicle is limited to speeds up 20 knots, half that of the LCAC, due to drag from its foam treads.
