It's not quite the same as the current engines, nor is it magneto hydrodynamic (caterpillar). It's a bit like a bigger version of the creep motors on boomers. Rather than two motors mechanically driving a screw shaft, it'll be an engine connected directly to the shaft, so there's no need for clutches or gearboxes for transmission which reduces the sound signature.
Like the article says, the Zumwalt will have a similar system, here's the wiki link for it:

The next big thing though is magnet related, the Permanent Magnet Motor, which should probably be very quiet indeed, whilst still maintaining a good level of horsepower.
