The USN trialled turbo-electric drive in BB40 New Mexico, constructed 1915-18 (her two sisters received geared turbines) and then incorporated it into Tennessee class (2 ships) and Colorado class (3 ships), all of which were laid down prior to the Washington Treaty being signed.One can perhaps also compare with warships. Americans, in particular, had an early love affair with electrical drives, as seen e.g. in the Lexington class battlecruisers (later converted to carriers). But once the Washington naval treaty with its displacement limits came into effect, this line of development seems to have died out in favor of the lighter and more compact mechanical reduction gearing for the turbines (there were some destroyer escorts and other minor combatants being built with electric drives, IIRC more due to gear-cutting for large reduction gearings being a bottleneck item rather than any inherent superiority).
New Mexico was converted to geared turbines during her 1931-33 modernisation with weight and space occupied being cited as problems. The later five all kept the turbo-electric machinery until they met the scrapman's axe post WW2. That because by the time these ships became due for modernisation inter-war, the USN preferred to spend what money was available on new Treaty limited battleships.
In WW2 most of the destroyer escorts built were either diesel or turbo electric. Only the Edsall (85 built) and John C Butler class (the last class, 83 built) used geared diesels and turbines respectively. That was from a total of over 550 including those completed as APD. But you are correct, it took a while for US industry to scale up its gear cutting industry.
