20 Inch Naval Gun

The 20 Inch(508mm) Naval Gun was a concept never followed upon in the real world, but it has poked up on NS. Originally it was designed by a US Civil War captain as a shore battery. There were a total of three of these 20" Rodman Guns constructed.

In the RL WWII, the concept of shipbourne 20" cannon appeared, and was in planning for the both the United States Navy Montana Class Battleship and for the "Super Yamato" class, Imperial Japanese Navy superbattleships. However, when the war ended, no keel had been laid and the age of the Aircraft Carrier had already begun. The plans for the 20" Gun battle-wagons were scrapped, and the largest naval gun ever concieved never saw production.

Had it been created, the 20" Naval Gun would have fired a half-ton shell at unknown ranges.
