USS Helios (ARB-12) was one of twelve Aristaeus-class battle damage repair ships built for the United States Navy during World War II. Named for Helios (in Greek mythology, the sun-god, represented as driving a four-horse chariot through the heavens), she was the only U.S. Naval vessel to bear the name. Originally laid down as LST-1127, the ship was launched on 14 February 1945 by the Chicago Bridge & Iron Company of Seneca, Illinois; sponsored by Mrs. Emery Adams; and commissioned on 26 February 1945 with Lieutenant Adam W. Melohusky in command.
