If your going to turn a BB in to a Kiev, why keep the X or rear gun at all. The elevator should replace the rear 16" and a raised flight deck. Leave a couple of 20mm on the rear flight deck.

#2 replace both 16" in the 1 and 2 and replace #1 with AA Missiles and in the #2 with Tomhawks. that still leaves room on the side for high rate Marks 5/54s and the Harpoons in place. You also can keep some RIM-116s on board as well.

#3 AQs for the Air Arm, I would think that 4 F-35s, 1 SeaHawk and 2 AW-1s with 2 blades instead of the 4 blades would work better for storage.

I did 3 types of Kievs for Kunzet that used the Crusier as the base ship. I took 3 Carriers and cut and sanded the flight decks down to fit on the rear of the aft deck.

The first one was just a deck to the aft housing, the 2nd ran pasted on the port side and the last one had flight deack just like the BBG-21, but was solid decking.

Either way you go, you can't go sailing alone and massed have the same protction as that of a CVN battle group.

Your BB doens't need a fish in the side to sink it but one under the keel with a large AIR bubble will do the trick.
