Everyone else probably knows about this and my Google-fu fails me. But if we don't, its an Axis capital ship I wasn't familiar with anyways so if we can play and learn all the better.
Far as its service, it got bombed during the war at least.
This is from the ForuMINI Navies subforum... found HERE
...although, based on what Team Neptune did with Unryu, some would say the Capacity and AA values are off...but I doubt using the card as-is would unbalance the game or anything.
