    Kenworth-Boeing gas-powered turbine truck

    Apparently the gas turbine in question (Model 502) was originally developed in response to a USN requirement, presumably on behalf of the USMC. I wonder what the intended vehicle was? https://www.hemmings.com/stories/2011/05/09/turbine-powered-oddities-no-466-the-see-through-kenworth-boeing...

    USN Fleet Carrier Studies (Fall 1945)

    A comprehensive source is Norman Friedman's "U.S. Aircraft Carriers". "By 1945, the Essex class was considered unsuited to the new generation of naval aircraft. The 1945 fleet carrier was to have solved such problems in a hull suited to mass production". Also incorporating those learned from...

    How would earlier Soviet carriers affect USN developement?

    Let's assume that USSR started to experiment with carriers in late 1920s, with planned rebuild of the training ship "Okean" into the light/training carrier "Komsomolets".
