History

After the Wyoming-class dreadnoughts were completed in 1912, the United States Navy halted construction of 12-inch guns in favour of larger 14-inch and later 16-inch guns for their battleships. However, they began to re-evaluate their naval forces after the rise of German "pocket battleships" such as the Admiral Graf Spee and Scharnhorst along with the planned Japanese B-65 which were all designed to counter the 8-inch gun heavy cruisers codified by the 1922 Washington Naval Treaty. As a result, the United States began construction of what became the Alaska-class large cruiser to counter these threats. The 12-inch was thus revived as the 12-inch/50 Mark 8. Designed to fire a new armour-piercing "super heavy" shell to better penetrate deck armour while retaining side plate penetration capabilities, this gun had superior characteristics to the pre-Treaty 14-inch guns. The 12"/50 Mark 8 was only used on the USS Alaska and USS Guam.
