The Pennsylvania-class battleships of the United States Navy were an enlargement of the Nevada class; having two additional 14-inch (356 mm) 45-caliber main battery guns, greater length and displacement, four propellers and slightly higher speed. They also had a relatively large secondary battery of 5-inch (127 mm) 51-caliber guns, which was soon reduced when many of the guns' locations proved vulnerable to high seas.
