A couple of months back, DARPA announced it’d been working on developing technologies to help during natural or “man-made” disasters, and this TEMP plan (Tactically Expandable Maritime Platform) included the addition of four key modular systems — one of which was sea-delivery vehicles such as that monstrous one pictured above. Dubbed Captive Air Amphibious Transporters, or CAAT for short, the rugged wheeler gets its drive-on-agua powers from air-filled pontoons, with its main purpose being to carry “containers over water and directly onto shore.” However, according to DARPA’s program manager, Scott Littlefield, it is more about the big picture, saying, “To allow military ships and aircraft to focus on unique military missions they alone can fulfill, it makes sense to develop technologies to leverage standard commercial container ships.
