13.7 ratio that is less efficient meaning more power is required to attain a given speed through the water. Higher power means higher RPM, increasing the risk of blade cavitation which is a catasprophe for stealthy submariners!

Well, I guess General Dynamics - Electric Boat are bunch of idiots.

“Well, I guess General Dynamics - Electric Boat are bunch of idiots.”

Not at all; they are competing for additional business, and if I had to guess, I would say that at slow, on station, operational speeds, the additional power requirements would be negligible. The blanket statement that speed would not be sacrificed is kinda like one of those Obama promises - “it all depends on the details”!
