This drawing shows my idea of how would IJN Shinano would looked like if finished to the original design not only as a fleet carrier based on the hull of a Yamato class battleship but as with the original armament of 10cm Type 98 DP-AA guns. I've extended the maintenance area forward of the forward elevator to provide better aircraft service capabilities, somewhat different light AA layout including twin 25mm Type 96 AA guns, full aircraft net protection for the sides and enhanced radar set of added Type 22 surface search radars on the aft part of the funnel as well as other minor changes like cables and such. The
My aircraft complement as follows:
25+1 Mitsubishi A7M Reppu / Sam Fighters
10 Yokosuka D4Y Suisei / Judy Dive Bombers (6 of them on the deck)
10+1 Aichi B7A Ryusei / Grace Torpedo-Dive Bombers
or 17+1 Aichi B7A Ryusei / Grace Torpedo-Dive Bombers
6+1 Nakajima C6N Saiun / Myrt reconnaisance planes
