The Navy has now issued at least one-fourth of the design work and begun further advancing work on systems such as a stealthy "electric drive" propulsion system for the emerging nuclear-armed Columbia-Class ballistic missile submarines by 2021… link |

Interesting, but Popular Science reported this "new technological breakthrough" in stealthy sub design about a year ago: link |

It's certainly the design goal for the Columbia-class. I mean, they need to be at least as quiet as the Ohio-class, and Ohios are a hole in the water. You find an Ohio by listening for where the ocean noise isn't. The pumpjet propulsor is quieter than an unshrouded screw, and going to an all-electric drivetrain allows you to eliminate the reduction gearbox. If you think transmission whine is bad in a car, imagine how noisy it is when you need to turn 65,000hp at 30,000rpm down to hundreds of rpm. Just those two items will do a huge job quieting the ship. |
