Would the US Navy keep turbo-electric drive without treaties?

A propulsion debate weighs machinery efficiency against subdivision, protection, and the geometric constraints imposed by the Panama Canal.

Question

Without naval treaties, would the US Navy retain turbo-electric propulsion for fast battleships?

Short answer

The panel divides: geared turbines offer better power density and weight, while continued development of turbo-electric drive could preserve layout and survivability advantages under Panama Canal limits.

Notes

The machinery choice involves competing advantages. Geared turbines become more compact and weight-efficient, but turbo-electric plants can be arranged as discrete generating units with strong separation and survivability. The Panama Canal also matters because machinery layout and hull form have to fit a fixed beam, so efficiency alone does not decide the best propulsion system.
