I would say "What about The Iron Giant?", but the film was practically made on that era (M41 tanks, f-86 jets, M1 Garands and carbines used, bazookas, no choppers, not black people with important roles...). Minus the Nautilus of course, which didn´t have nukes until the sixties.

They had a pretty good representation of late 50s clothing, actually...just simplified for easier animation. :)
And damn good weapons from the Korean War!
