With the end of the war in September 1945, "Arkansas" was employed with Operation Magic Carpet, repatriating American soldiers in the Pacific. "Wyoming" remained in service briefly after the war, though she was decommissioned in August 1947. She was sold for scrap in October and subsequently broken up. "Arkansas" was instead retained for use as a target ship during the Operation Crossroads nuclear tests in mid-1946. She survived the first test, an air-burst code-named ABLE, though the second experiment, an underwater detonation code-named BAKER, sank the ship.
