context_page_description: NAeL Minas Gerais was a Colossus-class aircraft carrier operated by the Marinha do Brasil from 1960 until 2001. The ship was laid down for the United Kingdom's 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 to Brazil in 1956.
  The ship 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.
context_section_description: In 1965, President Humberto de Alencar Castelo Branco permitted the operation of helicopters to the Navy, fixed-wing aircraft were to remain the responsibility of the Força Aérea Brasileira (FAB, Brazilian Air Force). As a result, Minas Gerais was required to embark two air groups: the Navy operated helicopters while the Air Force operated S-2 Tracker aircraft. Consequently, the ship spent most of her Brazilian career operating as an anti-submarine warfare carrier.
  From 1976 to 1981, the ship underwent a major refit. Work included the installation of a datalink to improve co-operation with Niteroi-class frigates, updates to the radar suite, and other work to extend the carrier's life expectancy into the 1990s. In 1988, engine problems, combined with the inability for Argentina to fund a required modernisation of ARA Veinticinco de Mayo, saw the Colossus-class carrier confined to port, making Minas Gerais the only active aircraft carrier in the South American region. In December 1987, Minas Gerais herself was laid up after participating in Operation Dragon XXIII because of problems with her aircraft catapult. Although unable to operate as an aircraft carrier, the ship saw use over the following years in training exercises as an amphibious assault ship; using an air group of Eurocopter AS532 Cougar and Eurocopter AS350 Squirrel helicopters to transport Marines ashore.
  Minas Gerais underwent a modernisation refit from July 1991 to October 1993. This included the overhaul of the boilers and engines, integration of a SICONTA command system, two new navigation radars and Scanter-MIL landing radar were installed, and preparation for the installation of Simbad launchers for Mistral surface-to-air missiles. The launchers themselves were installed in 1994, with the ten Bofors removed at the same time. The Bofors could be reinstalled to complement the ship's armament if needed. In November 1993, the carrier conducted a joint exercise with the Argentine Navy, where Argentine pilots flying Dassault-Breguet Super Étendard aircraft performed 177 touch-and-go landings, in order to maintain their carrier landing qualifications while Veinticinco de Mayo was out of service.
  During 1995 and 1996, the ability to operate fixed-wing aircraft was restored to Minas Gerais, after the catapult from the decommissioned Veinticinco de Mayo was acquired and installed. In 1997, Minas Gerais was loaned an A-4Q airframe by the Argentine Aviación Naval (Naval Aviation) for deck-handling and interface trials. This was in lead-up to the 1999 acquisition of 20 A-4KU Skyhawks and three TA-4KU trainer aircraft from the Kuwait Air Force for US$70 million. This was the first time since the carrier's commissioning that Força Aeronaval da Marinha (Brazilian Navy Aviation) had been permitted to own and operate fixed-wing aircraft. The 23 aircraft were formed as the First Intercept and Attack Squadron, had all entered service by early 2000, and began carrier operations in late October 2000. In order to operate the new fighters, Minas Gerais underwent a major refit at the Arsenal de Marinha do Rio de Janeiro. The main purpose of this refit was to upgrade the catapult to launch Skyhawks.
