While Yamato-1 proved the viability of magnetohydrodynamic propulsion, the system took up almost the entire ship just for a top speed of eight knots. DARPA aims to do much better.

A Rocket-Based-Combined-Cycle (RBCC) propulsion system employing ducted rocket operation and MHD airbreathing to accelerate the vehicle to Mach 12 in about 4 minutes within earth’s atmosphere, and ...

A radically new propulsion system for boats and submarines appears feasible for development if financial backers can be found, Argonne National Laboratory scientists have concluded after six months… ...

There were a studies published in 2006 and 2008 that looked at making a fusion rocket using dense plasma focus and air-breathing MHD propulsion. These system proposals would work even if Lawrenceville ...

DARPA, the US Defense Advanced Research Projects Agency, is now working on developing a magnet-driven silent water propulsion system – the magnetohydrodynamic (MHD) drive. The primary reason is to ...

Developers have had some success over the decades demonstrating MHD drive technology on a small scale, but it has been inefficient and impractical for full-scale systems. HRL's new approach to MHD ...

The system promises to make quieter submarines that are much harder to detect, a major leap for China in a field where it lags a generation or more behind the West.

A mysterious silent propulsion system reminiscent of author Tom Clancy’s fictional submarine “Red October” went to sea in real life Tuesday – not at a Russian naval base but in Japan’s ...

MALIBU, Calif., April 02, 2025--HRL Laboratories, LLC has demonstrated proof-of-concept on a unique approach to achieve a silent pumping system that replaces traditional mechanical moving parts ...

HRL Laboratories, LLC has demonstrated proof-of-concept on a unique approach to achieve a silent pumping system that replaces traditional mechanical moving parts with an electric current and a ...
