USS Washington (BB-47), a Colorado-class battleship, was the second ship of the United States Navy named in honor of the 42nd state. Her keel was laid down on 30 June 1919 at Camden, New Jersey, by the New York Shipbuilding Corporation. She was launched on 1 September 1921.
On 8 February 1922, two days after the signing of the Washington Naval Treaty for the Limitation of Naval Armaments, all construction work ceased on the 75.9%-completed super dreadnought. After a breif time the USN realized it could convert the ship into a CV as it could be cut under the unlimited 27,000t WNT limit (so not count as one of USN two conversions). This would give a slow and short CV but it was better than nothing and would save a lot of cash so she was slowly finished in late 20s to join Lex and Saratoga against the advice of some air minded officers. CV4 was to spend her life with the gun line due to her lacking speed mainly to provide fighters and spotters for the fleet. She missed pearl due to transport duties and then spent the war mostly providing CAP for invasion forces.
(apologies to the two original artists this is very much a cut and kit bash)
