The US Marines recently displayed a half-scale model of their proposed amphibious vehicle – the Ultra Heavy-Lift Amphibious Connector (UHAC) – during Rim of the Pacific (RIMPAC) exercise 2014.
The UHAC prototype managed to travel at 7 km/h in water and could get over 1 metre-high sea walls. The full-scale model will be able to reach 40 km/h and scale up to 3 metre-high sea walls.
The model consists of two tracks that are made out of captured-air foam blocks, which gives the vehicle the propulsion it needs for land and sea travel.
