USS Washington (BB-56) was the second and final member of the North Carolina class of fast battleships, the first vessel of the type built for the United States Navy. Built under the Washington Treaty system, North Carolina's design was limited in displacement and armament, though the United States used a clause in the Second London Naval Treaty to increase the main battery from the original armament of nine 14 in (356 mm) guns to nine 16 in (406 mm) guns. The ship was laid down in 1938 and completed in May 1941, while the United States was still neutral during World War II. Her initial career was spent training along the East Coast of the United States until Japan attacked Pearl Harbor on 7 December 1941, bringing the United States into the war.

The North Carolina class were a pair of fast battleships, North Carolina and Washington, built for the United States Navy in the late 1930s and early 1940s.
North Carolina underway on 3 June 1946. By this time, many of the light anti-aircraft weapons (Bofors 40 mm and Oerlikon 20 mm) mounted during the war had been removed, while more modern radars had been mounted on its fore and main masts.

The 32,250-long-ton (32,770 t) design "A" was one of the first proposals. Unlike "B" and "C", it was far below the treaty-mandated limit of 35,000–tons. It would have carried nine 14-inch guns in its main battery; although all of the turrets were forward of the superstructure, the guns could still fire forward provided that they were elevated to 4.5 degrees or more. The secondary battery planned was twelve 5-inch (127 mm) were unusually arranged in triple mounts.
