{{USS|Washington|BB-47}} was the second ship of the United States Navy named in honor of [[Washington (state)|the 42nd state]]. Her keel was laid down on 30 June 1919 by the New York Shipbuilding Corporation of Camden, New Jersey.  She was launched on 1 September 1921, but on 8 February 1922, two days after the signing of the Washington Naval Treaty, all construction work ceased on the 75.9% completed dreadnought.{{sfn|DANFS Washington (BB-47)}}{{sfn|Ferguson|2007|p=57}}

The ship was towed out to sea off the [[Virginia Capes]] in November 1924 to be used as a gunnery target. On the first day of testing, the ship was hit by two {{convert|400|lb|adj=on}} torpedoes and three {{convert|1|ST}} near-miss bombs with minor damage and a list of three degrees. On that day, the ship had 400&nbsp;pounds of TNT detonated on board, but she remained afloat. Two days later, the ship was hit by fourteen {{convert|14|in|adj=on|sp=us}} shells dropped from {{convert|4000|ft}}, but only one penetrated. The ship was finally sunk on 26 November 1924 by the battleships {{USS|New York|BB-34|2}} and {{USS|Texas|BB-35|2}} with fourteen 14-inch shell hits. After the test, it was determined that the existing deck armor on battleships was inadequate, and that future battleships should be fitted with triple bottoms.{{sfn|Friedman|1985|p=186}}
