Marine's New "UHAC" Boat/Tank Hybrid in Action

Video of the Marine amphibious landing during RIMPAC 2014. The Marines will be testing a prototype amphibious vehicle called UHAC (Ultra Heavy-Lift Amphibious Connector). The Ultra Heavy-Lift Amphibious Connector is being developed as an option to replace the Landing Craft Air Cushioned (LCAC) Hovercraft. Lt. Col. Don Gordon, the current technology officer at MCWL, said the UHAC is one of those experimental technologies that displays a possible capability of being able to insert Marines in areas where current technology wouldn't be able to insert them based on current systems that are fielded. 

The UHAC prototype is a ship-to-shore connector and is half the size of the intended machine. Currently, the UHAC travels at four knots using a track system with floatation-like pads that propels itself through different terrain. Credit: Gunnery Sgt. Jeremy Vought, Cpl. Matthew J. Bragg.

The full-scale UHAC can haul three U.S. Abrams main battle tanks at a time. Its lightweight track segments that make the treads give the fully loaded vehicle a ground pressure of just a few pounds per square inch—lighter than an adult human’s footstep. “In places where a person would sink into the mud, UHAC would walk right over,” says Frank Leban, deputy UHAC program manager at ONR.
