dynamic balancer for brake rotor

I have a question about Navy large ship engines?

Do Navy large ships use transmissions with their engines? And - is there a particular brand of engine that the Navy uses in their ships? I am guessing a brand like GM.


only thing i know is that the navy uses nuclear engines to power their ships
