USS Menelaus (ARL-13) 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 Menelaus, she was the only US Naval vessel to bear the name.

A repair ship is a naval auxiliary ship designed to provide maintenance support to warships. Repair ships provide similar services to destroyer, submarine and seaplane tenders or depot ships, but may offer a broader range of repair capability including equipment and personnel for repair of more significant machinery failures or battle damage.
