When I ws in we escorted the CVA America which I believe was WWII era, its since been decommisioned. My ship DDG-14 was built 1963 and decommisioned in 1992 or so.
Things have changed. When I was in 1975-1980 we called taking stores on at sea from a larger ship "Underway Replenishment" (UNREP) Now they call it "Connected Replenishment" (CONREP). In my day the process of UNREP was classified because the Russians did not know how to do it side by side, they did it end to end, one ship following another. Just today I was watching a thing on carriers and they pretty much showed the whole process, mechanics and everything, right on the boob tube. If you really want to get a feel for the size of a carrier, go on board one. I went onto one, can't remember which, and walked up 6 stories of stairs to the entrance and I was still quite a ways below the flight deck. I was in awe. Also, the top of our mast was 60 ft above the water and when we unrepped from a carrier it too topped out way below the flight deck. it was like, "WOWWW! Our mast doesn't even reach the flight deck!"
