I know that this is my first post in the forums, but please don't dismiss this with 'Squeaker!!!!' etc
I think that a valuable addition to the MA would be the
PBY Catalina - Wikipedia.
So far, there aren't any amphibious aircraft in the game, and I think one would be an excellent new plane.
Another good link is:
PBY.com Catalinas might be an excellent complement to the PT boat, and be able to carry more ordinance, but greater distances at not much higher speeds. Also, unlike the B-29 idea, this would not need to be perked, as its low speed would make it easy to be intercepted, but would also make it difficult for fighters not to overshoot.
Also, to help its advantages at low altitude, perhaps HTC could make the icon be very hard to see when the plane's at or near ground level. In my opinion such an aircraft would be spawned from ports, airfields, and CVs. Also, having a long range patrol craft would make it easier to scout around CVs and bases. Also, it might be a useful (and more versatile)resupply plane in addition to the C-47
Finally, I know that without having submarines (and almost non existent nights) in AH some ppl will think that a PBY would have really limited usefulness, however I think its value as a difficult to detect scout, as well as its history, would make it popular definitely in the Early and Mid War arenas, but also in the Late war arena.
