THE US NAVY'S NEW SEA TRAIN
DARPA'S Impressive Tech R&D Project for US Navy Super: DARPA Linked Autonomous Ships This is a highly impressive and innovative new project by DARPA, the US Defense Department's Advanced Research Projects Agency. DARPA is developing unmanned surface ships (USVs) that would physically link together like train cars to cross the ocean as a sea train. Linking the ships together lets them overcome wave resistance and make much longer trips with much greater efficiency. The Sea Train concept envisions many unmanned ships physically linked together to traverse oceans and grow the US Naval fleet. Naval Force of Unmanned Vehicles The Navy is investing in all sizes of USVs, including large 300 ft. ones and medium sized ones of 39 to 154 feet. DARPA's Sea Train project is focused on the medium sized USVs that are more efficient, more difficult to detect but less capable of making long journeys. The Sea Train concept should extend their travel distances across
