NAe São Paulo (A12) is a Clemenceau-class aircraft carrier currently in service with the Brazilian Navy. The São Paulo was first commissioned in 1963 as the French Navy's Foch, and transferred to Brazil in 2000.
São Paulo is the flagship of the Brazilian Navy. It replaced the World War II-era carrier Minas Gerais, which was in commission for over 40 years. The São Paulo is newer, bigger, faster and has greater operational capacity than its predecessor.
The former French Foch was bought to replace the aged Minas Gerais at a bargain price of US$12 million in 2000, no aircraft included. The government had already purchased a flotilla of used A-4 Skyhawk fighters from Kuwait for $70 million. Brazil's A-4s are capable of carrying armament including rockets, free-fall bombs and Sidewinder air-to-air missiles, though the São Paulo currently serves mainly to train pilots to fly carrier operations."The transfer of the aircraft carrier São Paulo to the Operative Sector of the Navy adds to our naval power an important magnification in its ability of defense of the Brazilian interests at sea. A country as ours, possessing an extensive coast, with more than 7,000 kilometers of coast, requires a naval power compatible with its stature in the international scene. Today, as before, Brazil is concerned about implementing concrete measures that offer the nation the guarantee of respect to its sovereignty. We are and we will always be a nation that fights for peace, however, that does not mean being able to do without modern Armed Forces, enabled and endowed with adequate dissuasive potential. Few countries, even today, have the capacity to operate with efficiency in the high seas. It is important that Brazil continues to be one of them."
Since its construction, the ship has received multiple upgrades over the years, leaving it with a diverse range of technologies. In its current form, it is expected to remain effective in its role for the foreseeable future, though further modernization efforts are expected as it is converted into a combat ready vessel. Twenty-three A-4 Skyhawk have been acquired (designated AF-1) to compose the fighter-bomber group of São Paulo, together with the existing helicopters already in the national defense inventory.
The aircraft carrier São Paulo was constructed in France from 1957 to 1960. It served the French Navy as Foch. Its purchase by the Brazilian government in September 2000 while still operational was an unknown process for a ship of this caliber, and it was received by the Brazilian Navy in only two months and fifteen days and incorporated on 15 November 2000. The incorporation of São Paulo and the AF-1 to the Navy of Brazil realized a long-held goal of being able to carry through the aerial defense of the naval forces with fixed-wing aircraft.
In the first three years of service as São Paulo, the ship completed several missions, some in foreign waters (particularly Operations ARAEX, PASSEX, and TEMPEREX which is annually used to qualify and train Super Etendards and S-2T Turbo Trackers of the Argentine Navy) 
Upgrade (2005–2010) and sea trials
During 2005–10, the São Paulo underwent an extensive modernization program. The upgrade included: inspection and repair of the steam turbines; maintenance of the surface condensers; retubing of boilers; repair of two high-pressure compressors; revision of the alternating current electrical generator and purchase of spare parts; maintenance of pumps, valves and structural items; purchase of two API oil-water separators; installation of two water cooling units; upgrade of the chemical oxygen generator; repair and treatment of oil tanks; substitution of the Naval Tactical Data System; installation of a closed-circuit television system; installation of IFF transponder; installation of MAGE system (ESM); flight deck inspection, repair and painting; upgrade of the Optical Landing System processing unit; revision of the aircraft catapults. The upgrade was complete in July 2009, and the São Paulo was initially due to be fully operational by August 2010.
Twelve Brazilian Navy A-4 Skyhawk will also be upgraded by Embraer at a cost of $140 million. The upgrade will be similar to the ones done for the AMX and F-5EM aircraft of the Brazilian Air Force. The program includes restoring the aircraft and their current systems, as well as implementing new avionics, radar, power production, and autonomous oxygen generating systems. Possible weapons to be included in the upgrade are Python 4 and Derby AAMS.
According to an article in the October 2010 issue of Air Forces Monthly[clarification needed][page needed], it has been confirmed that Brazil has purchased EX-USN C-1 Trader airframes, ex-Australian and ex-Uruguayan airframes for conversion into AEW planes and Tanker aircraft. All the planes are to upgraded to S-2T Turbo Tracker configuration with Honeywell TPE 331-14GR engines. The purchase includes 9 airframes, 2 for tanker conversion to refuel the AF-1 Skyhawks, and 3 for AEW. The rest will be for spares or cargo duties. The AEW radar requirement is to have a range of 250 miles at 25,000 feet. Operational lifespan for the airframes is to be 10 years. They are to be ready by 2011 and 2012.
The São Paulo's SH-3 helicopter fleet is to be replaced by six ex-USN S-70B Seahawk helicopters. They were purchased in 2008, upgraded and refurbished for delivery. The helicopters and a package of engines and support equipment were expected to be delivered in 2009.
At the end of 2010, sea trials began, and as of 2011 the São Paulo has been evaluated by the CIASA (Inspection Commission and Training Advisory). It is expected to rejoin the fleet in late 2011.
It is actively used for the qualification and re-qualification of rotary and fixed-wing pilots (with about 500 catapult launches) and the first Brazilian exercises to practice carrier-based attack missions.
