Dragon Warbirds used to make carrier decks to go with their planes. Corgi as well and some of those had figures with the deck, and ground crews for select aircraft. To my knowledge they didn't sell them separately. I have a couple of the Dragon decks and use them. They look good and are made out of plastic.
Hobby Master also makes them though and you can buy them for 1:48 or 1:72 planes in American or Japanese carrier types. I do believe they are made of solid ABS plastic.

I've never bought them separately but the ones you get with some of their planes they are made out of paper. I just bought a Skymax/ Hobby Master Val and it had a paper carrier deck.
Would like to know about pre-painted figures myself. I think there are ground crew figures for modern aircraft, not so sure about WWII types.
So far I have only bought the HM pilots packs for my planes without pilots.
