USS Antaeus (AS-21/AG-67) was a commercial passenger liner that the United States Navy acquired in World War II.

[2] In 1939, the ship was chartered to the United States Lines for one voyage to carry American construction workers to air base projects in Bermuda.

The ship then began shuttling troops to points in the Caribbean, the Panama Canal Zone, and to Argentia, Newfoundland, from bases at New York City and Davisville, Rhode Island.

She arrived off Okinawa on 13 June, embarked men wounded in the fighting ashore, survived unscathed despite almost constant Japanese air attack against Allied shipping in the area, and safely delivered her patients to a hospital on Guam.

With a bed capacity of 792 and a complement of 440, Rescue provided hospital services, consultation, preventative medicine, and casualty evacuation.

The ship was put in permanent reserve on 28 September 1948 in Olympia, Washington, and remained there until being sold for scrap in October of that year.
