Sure ... and there are OTHER planes that do the same thing the Storch does MUCH better (faster, armed, etc) ... But the Game Experience goes BEYOND THAT ... AND - just to subvert the obvious argument that the Storch is STOL and will be available from Vehicle bases ... The PBY is AMPHIBIOUS and could function from Ports and Task Group areas.
I'm all for adding a plane that used broken beer bottles and regular ordnance for night time harrassment bombing missions but sadly, as I and others have mentioned, the plane just isn't viable.
As a scout...bombers or even a heavy fighter would be a better option for seeking out the enemy fleet. The PBY brings nothing special to the table in this regard. Yes, in real life the PBY carried a primitive ASR system but that was used primarily at night for searching for shipping and navigation, in the daytime the crews relied on the Mark I I-Ball with the binocular extensions as this was more reliable for finding surface targets than the ASR radar system. You'd be able to find a fleet just as easily in a bomber or a fighter and have a higher rate of survivability.
As a bomber...as the crews in real life found out, daytime attacks in the Catalina were near suicidal due to the low speed of the plane, that is why offensive operations were done at night. In AH, it would just be cannon fodder and most likely never reach the target if it is defended.
As a supply plane...in the early years of the war, it was pressed into service to ferry supplies to the various as teh Japanese were over running the Pacific. One of the most famous of these runs was the attempt to resupply Corregidor in late December of '41 and to carry out personnel. The supplies were limited though, mostly ammunition and medical supplies as the Catalina couldn't really carry anything much larger than that. In game it would only probably be limited to carrying vehicle supplies and it would have to land those as it couldn't air drop them. As for carrying personnel, it would be rather limited as well.
It takes more than "just the experience of flying it" for a plane to be viable for the game...flying just for the experience would get tiring after awhile if it resulted in your death 9 out of 10 times before you were even close to the target.
the Japanese Emily flying boat would be much more viable for AH.
