The Batillus-class supertanker was a class of tanker ships built in France at the end of the 1970s. Four such ships were built between 1976 and 1979—serving until the final one was scrapped in 2003. They were built in the Bassin C dock of the Chantiers de l'Atlantique shipyards at Saint Nazaire, France. Measured by gross tonnage, these were the largest ships of any type ever constructed.
