USS Romulus (ARL-22) was laid down as a United States Navy LST-542-class tank landing ship but converted to one of 39 Achelous-class repair ships that were used for repairing landing craft during World War II. Named for Romulus (along with Remus, one of the legendary twin sons of Mars and the Vestal Rhea Silvia), she was the only US Naval vessel to bear the name.
