Magnet-Powered Subs Like ‘Red October’ Are Coming

The Pentagon’s advanced science division is taking a new look at a technology that promises to revolutionize how warships travel and fight in the world’s oceans. The Defense Advanced Research Projects Agency (DARPA) is challenging industry to see if development of state-of-the-art magnetohydrodynamic (MHD) drive systems could become reality. MHDs, which use electromagnetism instead of physical propellers, promise near-silent propulsion, a boon to submarines—and the ships that hunt them. Put simply, this means warships, both on and under the sea, could someday sail without moving parts.
