ABSTRACT:
A power driven tracked amphibious vehicle is disclosed for moving troops from ships to shore at speeds in excess of 25 miles per hour. The vehicle includes a pair of hydrofoil assemblies each pivoted to the vehicle for movement between an operative water mode position with the hydrofoils and inline water jet propulsion units submerged in water for propelling the vehicle while in water, and a land mode with the hydrofoils and water jet propulsion units raised above the tracks for propelling the vehicle on land. When in the water mode the tracks are raised a short distance, and the track covers and bow flaps are positioned below the tracks for minimizing drag on the vehicle.
