The USS Chapultepec was a U.S. Navy escort airplane carrier built and launched in 1942 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.
The Chapultepec and her sister ship, the Trenton sailed for the Sandwich Islands immediately after commissioning to replace the sunken Remembrance. On their voyage, they escorted a convoy of freighters and tankers to keep the islands supplied.
