I wonder how many Civil War technologies remained dominant in WWII; probably not much in the navy. Fighter planes are that old too. And machine guns, and grenades, and even night vision goggles. But the aircraft carrier of today is very different from the aircraft carriers of WW2, and so is the rest of that equipment. Except the grenade.
