A-150 Design (Super Yamato)
Ultimate Battleship That Never Was - A-150 (Design A-150) was Japan's planned super-battleship. Design studies 1938-1941. Would have been largest battleships ever built: 98,000 tons full (vs Yamato's 72,800 tons). 510mm (20.1-inch) guns - largest battleship guns ever planned! (vs Yamato's 18.1-inch). Six guns in three twin turrets. 16-inch belt, 9-inch deck, 26-inch turret faces. 30 knots, 190,000 shp. Never laid down - cancelled due to war priorities (shift to carrier warfare after Midway 1942, resources diverted to carriers/aircraft). Design studies only (preliminary plans, no construction). Symbol of battleship era's end - ultimate battleship concept obsolete before it could be built. A-150: Greatest "what-if" in naval history.
