NAe Sao Paulo is a Clemenceau class aircraft carrier of the Brazilian Navy, formerly the French Foch. Sao Paulo is the flagship of the Brazilian Navy. In the first three years of service as Sao Paulo, the ship completed several missions, some in foreign waters. While currently operational, budget cuts may result in the aircraft carrier being withdrawn from service. Sao Paulo currently serves mainly to train pilots to fly carrier operations.
The old French Foch was bought for US$12 million in 2000, without aircraft, while still operational. The Brazilian government had already purchased a several used A-4 Skyhawk strike aircraft from Kuwait for US$70 million to serve as carrier aircraft. On 15 November 2000, the Sao Paulo was commissioned in the Brazilian Navy.
