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