This was the largest battleship ever planned but never built
In the days before naval aviation and submarines, the battleship was the unchallenged king of the seas. Building a bigger and better ship with more and bigger guns was basically the order of the day, and it continued all the way up until the days before World War II, when the world reached peak battleship, and airplanes proved to be deadlier than the Navy ever imagined.
But America almost reached peak battleship before World War I was even a possibility, and it was possibly the biggest battleship ever conceived – it also might have been an ironic joke from someone who hated the Navy.
Benjamin Tillman, famous racist and Navy hater.
Benjamin Tillman was a U.S. Senator from South Carolina and a member of the Senate Naval Affairs Committee. He was annoyed at the Navy for coming to Congress every year to request money to build more and bigger battleships. Despite this pretty much being what the Navy is supposed to do, Tillman decided it would be best to just get the whole arms race out of the way and build the biggest possible battleship they could at the moment. This led to the creation of the Maximum Battleship design.
No, that's really what they called it.
Tillman hated the Navy's battleships, and everyone knew it, but when he requested the Department of the Navy just submit the plans for the biggest battleship they could, the Navy obliged him anyway. There were, however, restrictions on U.S. ship designs at the time. Namely, they had to fit through the Panama Canal.
The first design submitted was a massive 70,000 tons – almost 50 percent heavier than the modern Navy's USS Missouri – and this was in 1916. It carried 12 16-inch guns and had an armor thickness of 18 inches. In comparison, the Iowa-class battleships of World War II would carry just nine 16-inch guns and have a maximum armor thickness of 14.5 inches. The next iteration of Maximum Battleship designs would have 24 16-inch guns and an armor thickness of 13 inches. It was the third design that really took the cake, however.
Maximum Battleship III – also known as the Tillman III design – weighed 63,000 tons. It had the armor of the second design and the guns of the second design. It could even move at an absurd 30 knots, which is almost as fast as an Iowa-class ship and an insane speed for a ship of that size in 1916. This is a weight equal to the largest battleships ever actually built that moves even faster and was supposed to be built 20 years earlier. That wasn't the end of the attempt, though. There would be another.
The largest of the Tillman Designs.
The fourth design for Tillman featured the 24 guns and even thicker armor, coming in at 19 inches. It was clear by now the Navy wasn't expecting to get funding for these. The fourth design would displace 80,000 tons and was practically impossible to build with the technology of the day. In all, six designs were made, each bigger and more ridiculous than the last. It would be as big as the modern American supercarriers and carry the most and biggest weapons of anything on earth, on land, or on the oceans. And it would have been sunk just as easily with the advent of naval aviation.
