I don't know if this project already is here in shipbucket so i will only give a "new topic"
The 32,250-long-ton (32,770 t) design "A" was one of the first proposals. Unlike "B" and "C", it was far below the treaty-mandated limit of 35,000 long tons (36,000 t). It would have carried nine 14-inch (356 mm) guns in its main battery; although all of the turrets were forward of the superstructure, the guns could still fire forward provided that they were elevated to 4.5 degrees or more. The secondary battery planned was twelve 5-inch (130 mm) were unusually arranged in triple mounts.
"F" was an attempt to create a viable combination of an aircraft carrier and a battleship. With regards to the treaty limits, the design had an extremely comfortable margin with a standard displacement of 31,750 long tons (32,260 t; 35,560 ST). Three catapults were mounted on the bow, while a hangar located under that would contain ten bombers with wings folded. Two non-superfiring turrets would be mounted aft, both holding four 14-in guns.
"VII" harked back to the days of the slow battleships; with a top speed of 22 knots (25 mph; 41 km/h), it would have been only 1 knot (1.2 mph; 1.9 km/h) faster than the old ""standard" battleships. The weight gained from reducing the speed was added back in firepower and protection: "VII" would have had twelve 14-inch/50 caliber guns in four triple turrets and an immune zone against its own 14-inch gun between 21,400 and 30,000 yards (12.2 and 17.0 mi; 19.6 and 27.4 km).
"XVI" was one of the final proposals; after "XVI-C" was rejected, a modified version of this design was chosen for the North Carolinas. There were a few major differences between this and the final plan. For example, all exhaust was eventually trunked into two funnels as opposed to one, and the 5-in/38 caliber secondary battery was composed of all dual-mounted guns (no single).
