The PBY up to the -6 model were all used in ww2, but the -5a was the most produced of the aircraft. And why not allow it to land on concrete? Add it as a bomber, allow it to carry cargo, along with the ability to carry an ordinance payload, and let it take off from airfields, as well as ports (like the storch) and from the CV/crusier. Oh its too under armed to be added? It would be flying target practice? so is the storch, ju87, ju88, both japanese heavy bombers, and c47. I see all of them being used, and I have had several kills gunning in their turrets (where applicable). If you don't like it, don't fly it, leave that to someone else, but make the CV resupp-able. And heck! why not add floatplane fighters to take off from the CV and Ports? It would add another dimension to the game and make the ports less vulnerable, could even escort the PBY's, like we do now with any bomber formation or c47 drop.
