Pennsylvania-class battleship

Dreadnought battleship class of the United States Navy

The Pennsylvania class consisted of two super-dreadnought battleships built for the United States Navy just before the First World War. Named Pennsylvania and Arizona, after the American states of the same names, the two battleships were the United States' second battleship design to adhere to the "all or nothing" armor scheme. They were the newest American capital ships when the United States entered the First World War.
