There is a sort-of WIP MAD simulation that Peabody and keltos01 did several years ago. One version for the USN, another for the IJN. We're still working on the campaign itself, and haven't been able to look into finding and editing that just yet, but we will be. I'll see how "compatible" it would be as a general add-in mod, and then see if keltos01 and / or Peabody want to release it by itself. I've seen it at work, and the planes do pretty well "dog" you until they run out of depth charges... cool stuff... sort-of
