Frankenstein Warships: The Biggest Battleships Never Built

Also known as the Super Yamato-class, the Design A-150 battleship began in late 1938 and it was to be armed with at least six 510mm (20-inch) guns as well as dozens of smaller caliber weapons. The warship as it was originally envisioned was also 91,000 metric tons (90,000 long tons) and yet would be fast enough to maintain a speed of 30 knots – faster than the American Navy’s North Carolina-class battleships, which could maintain a speed of 27 knots.
