Aircraft carrier was laid down for the Royal Navy during World War II as HMS Vengeance, but was completed only shortly before the war’s end, and did not see combat. After stints as a training vessel and Arctic research ship, the carrier was loaned to the Royal Australian Navy from 1952 to 1955. She was returned to the British, who sold her in 1956 to Brazil.
Aircraft carrier underwent a four-year conversion in the Netherlands to make her capable of operating heavier naval aircraft. She was commissioned into the MB as Minas Gerais in 1960; the first purchased by a Latin American nation, but the second to enter service, behind the Argentinian ARA Independencia. Between 1987 and 1996, the carrier was unable to operate fixed-wing aircraft because of a defective catapult, and was retasked as a helicopter carrier and amphibious assault ship.
Minas Gerais remained in service until 2001, when she was replaced by NAe São Paulo. At the time of her decommissioning, she was the oldest operational aircraft carrier in the world, and the last operational unit of the World War II Light Fleet design. Despite attempts to preserve the carrier as a museum ship, and after several failed attempts to auction the ship off (including a listing on eBay), Minas Gerais was sold for scrap in 2004 and taken to Alang for breaking up.
