Seeking the Ultimate in Marine Stealth: DARPA Pursues Quest to Finally Make Magnetohydrodynamic Drive a Practical Reality 

August 20, 2025 Editorial Staff Comments Off on Seeking the Ultimate in Marine Stealth: DARPA Pursues Quest to Finally Make Magnetohydrodynamic Drive a Practical Reality 

Since the 1960s, academic, commercial and military researchers have attempted to realize a novel form of maritime propulsion involving no moving parts – no propeller, no drive shaft, no seals – just magnets and an electric current that silently propel a boat or submarine through water. It has been an elusive goal but tests are being conducted at Navy facilities this summer with an aim toward developing a practical, workable system.  […]
