Empresa Líneas Marítimas Argentinas (ELMA) was an Argentine cargo shipping line formed on September 30, 1960, after Juan Perón nationalised the shipping industry. The Argentine Maritime Lines Company involved the merger of two companies, both state: the Merchant Fleet of the State (FME) and Argentina Fleet of Navigation of Ultramar (FANU). It served Argentina's foreign trade until the 1990s, when the government of Carlos Menem declared its dissolution. At its peak its fleet had more than 60 ships. Ships sailed to Northern Europe, the United Kingdom, the Baltic Sea, the Mediterranean, the east coasts of the United States of America and Canada, the Gulf of Mexico, the Pacific, the Middle East and Far East and Africa.
