 (RN) as HMS Vengeance. She was laid down on 16 November 1942, and launched on 23 February 1944. Construction was completed on 15 January 1945, and Vengeance was commissioned into the RN.

The Colossus class carriers were intended to be 'disposable warships': they were to be operated during World War II and scrapped at the end of hostilities or within three years of entering service. Despite this prediction, the ship had a service life of over 55 years across three navies.

Early operational history

After commissioning, Vengeance was assigned to the 11th Aircraft Carrier Squadron, which was attached to the British Pacific Fleet

. The carrier arrived in Sydney, Australia in July 1945, but remained in the harbour for refits until the end of World War II. Vengeance operated in the waters of Asia until mid-1946, when she returned to England and was reassigned as a training vessel. In late 1948, Vengeance was converted for Arctic conditions, and from February 1949 to March 1949, she operated in Arctic waters as part of an experimental cruise to determine how well ships, aircraft, and personnel functioned in extreme cold.

From late 1952 until mid-1955, Vengeance was loaned to the Royal Australian Navy

 promised Brazilian admirals to acquire an aircraft carrier for the Marinha do Brasil (MB, Brazilian Navy). Kubitschek later claimed that this was to avoid a naval rebellion during his inauguration at the start of 1956, and despite believing in the "military uselessness" of the second-hand warship, the sale of Vengeance to Brazil for US$9 million went through on 14 December 1956.

From mid-1957 until December 1960, the carrier underwent a massive refit and reconstruction in the Netherlands. The work was carried out by Verolme Dock in Rotterdam, and cost US$27 million. The most visible change was the installation of an 8.5-degree angled flight deck. The size of the angle required that an accessway be built around the starboard side of the island superstructure; the weight acting as a counterbalance for the flight deck's portside overhang.

, reinforced hangar elevators, and a mirror landing aid, these modifications permitted the operation of jet aircraft up to 20000 pounds (9,071.8 kg) in weight. The carrier's island superstructure was replaced, and a lattice mast was fitted to support the new fire control system and radar suite. The ship's boiler capacity was increased, and internal electricity was converted to AC through the installation of four turbo generators and one diesel generator.

The carrier was commissioned into the Marinha do Brasil as NAeL Minas Gerais (named for Kubitschek's home state) on 6 December 1960. She departed Rotterdam for Rio de Janerio on 13 January 1961. The duration of the refit meant that while the carrier was the first purchased by a Latin America

n nation, she was the second to enter service, after another Colossus class carrier entered service with the Argentine Navy as ARA Independencia in July 1959.

Weapons and systems

During the ship's modernisation refit to become Minas Gerais, her armament was altered to consist of ten Bofors 40 mm anti-aircraft guns

 (2 quad mountings and 1 twin mounting), and two 47 mm saluting guns. In 1994, the Bofors were removed and replaced with two twin surface-to-air launchers for Mistral missile

s. If additional armament was required, the Bofors could be reinstalled.

By 1996, Minas Gerais was fitted with the following radars: a Lockheed SPS-40B for air search, a Plessey AWS 4 for surface search, a Signaal ZW06 for navigation, two SPG-34 for fire control, and a Scanter Mil-Par for CCA. The two search radars operate on NATO frequency bands designated E and F, the navigation and CCA radars operate on the NATO I band, and the fire control radars on both the I and J bands.

As of the mid 1990s, the carrier's air group consisted of six S-2E Trackers

 for $US70 million. Minas Gerais began operating these aircraft in late 2000.

Brazilian operational history

In 1965, President Humberto de Alencar Castello Branco outlawed the operation of fixed-wing aircraft by the MB; this remained 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

, saw the Colossus class carrier confined to port, making Minas Gerais the only active aircraft carrier in the South American region.

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, new CCA radar, and preparation for the installation of Simbad launchers for Mistral surface-to-air

, 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.

 for US$70 million. This was the first time since the carrier's commissioning that Forca 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.

Replacement and decommissioning

The replacement of Minas Gerais was first suggested in the early 1980s, as part of planned 15-year naval expansion program. Two different carrier designs were proposed. The first was for a 40,000 ton ship equipped with up to forty aircraft, including naval fighters. To complement this proposal, a plan to expand the Brazilian fleet air arm by acquiring second-hand A-4 Skyhawk

s from Kuwait or Israel was submitted. For this to happen, the 1965 ruling that prevented the MB from operating fixed-wing aircraft had to be overturned; a decision the FAB opposed. To make the purchase worthwhile, Minas Gerais would have to operate the aircraft until the replacement carrier entered service, which in turn required the installation of a modified steam catapult and arresting gear. As the ship had just emerged from a modernisation refit, this was an expensive proposition, and the Skyhawk acquisition plan was cancelled in October 1984. The Skyhawk plan was successfully revisited in the late 1990s. The second proposal was for a 25,000 ton helicopter carrier built to commercial standards. Later interpretations of this proposal suggested a ship similar to the Royal Navy's .

Replacement of Minas Gerais was under serious consideration by 1999; despite numerous refits and life-extending upgrades, the MB predicted that the carrier would require replacement before 2010. As well as the two proposals, consideration was given to acquiring a second-hand carrier, such as the French Navy's Foch

Foch was the second of the French Navy. She was the second warship named in honour of Marshal Ferdinand Foch, after a heavy cruiser commissioned in 1932, and scuttled in Toulon on 27 November 1942....

. One of the main issues in considering the replacement was the MB's significant investment in fixed-wing aviation in the late 1990s; a carrier capable of operating the recently-acquired Skyhawks would be more expensive to acquire and operate than a STOVL

 or helicopter carrier, but the cheaper concepts would require the refactoring of Brazilian naval aviation. In the end, Foch was acquired, renamed NAe São Paulo, and slated to commission into the Marinha do Brasil in April 2001.

Minas Gerais was decommissioned on 16 October 2001: the last of the World War II-era light aircraft carriers to leave service. At the time of her decommissioning, she was the oldest active aircraft carrier in the world (a title passed on to the 1961-commissioned ). The carrier was marked for sale in 2002, and was actively sought after by British naval associations for return to England and preservation as a museum ship

, although they were unable to raise the required money. Just before Christmas 2003, the carrier was listed for sale on auction website eBay
