Killea said the prototype tops out at about 5 mph on the water. The full-size version is expected to move about 25 mph at top speed, he said.

That’s about half the speed of the Navy’s hovercraft, the Landing Craft Air Cushion, or LCAC, an amphibious craft used to shuttle troops and materiel between ship and shore.

But the LCAC isn’t so adept at scrambling over rugged terrain, Killea said. The UHAC can, potentially carrying a heavy payload of supplies to typhoon-damaged areas during humanitarian relief missions.
