For the OTL ship of the same name, see USS Yorktown (CV). The USS Yorktown was a U.S. Navy escort airplane carrier built and launched during the Second Great War. She was a converted freighter whose superstructure had been removed and replaced with a flight deck and small starboard island. She carried 30 airplanes including divebombers, torpedo carriers and fighters. As such, her complement was about half that of a fleet carrier. Given her origins as a freighter, she couldn't do more than 18 knots as compared to a regular warship's 30.
