Navy of Brazil during the Cold War (1947-1991)
The participation of the Brazilian Navy in World War II (1939-1945) was essentially antisubmarine, in the convoy of trains - an activity for which it was not prepared at first. The newly created Brazilian Air Force (1941), of the union of Army and Navy aviation, also lacked state-of-the-art equipment.
The aircraft carrier Minas Gerais was a modern unit and operated during the Cold War as the nucleus of groups of hunting and destruction of submarines, equipped with naval antisubmarine helicopters and P-16 Tracker aircraft of the FAB

The ships of the Brazilian Fleet were largely still of World War I, with few new ships that were not also suitable for the anti-submarine war.
Brazil was caught by surprise by the War and its Merchant Marine and economy suffered with the attacks of German and Italian submarines to our maritime traffic, responsible for the export-import and for the supply of the North and the Northeast.
At the beginning of the conflict, Brazil had two battleships still of the 1910 Fleet, both obsolete. Minas Gerais had been modernized in the period 1934-39, using oil instead of coal in its boilers. São Paulo was still charcoal-fueled.
The cruisers Bahia and Rio Grande do Sul had been modernized in 1925-26 and the seven destroyers, also veterans of 1910, were in so precarious a state that they were deactivated during the war.
The six new "Carioca" class sweepers were eventually converted into antisubmarine corvettes.
The Military Assistance Program
Brazil continued to have substantial US aid through the Military Aid Program (MAP), whereby the country received modest prices, surplus material from the Second War, from spare ships.
The strategic design of the Brazilian Navy continued to have a defensive character, dedicated to anti-submarine warfare, integrated with the great US strategy of combating the Soviet submarine threat to maritime traffic in the event of an East-West outbreak.
The Cold War of the Western bloc against communist countries under the leadership of the USSR is the main factor for the strengthening of Brazilian Naval Power in this period.
In the first years after the end of World War II, the navy dedicated itself especially to support activities, both in the construction of naval bases and in the acquisition of ships. The administrations of Admiral Silvio de Noronha and Admiral Renato de Almeida Guillobel expended great effort in expanding and improving the infrastructure in support of the naval means.
Ships received in the aftermath of the war until 1952, with the exception of the light-cruisers Barroso and Tamandaré, of the "Brooklin" class of the U.S. Navy, remnants of the war, were auxiliary ships. The ship was shipped Guanabara, former German sailboat, Ilha Grande tanker, tanker adapted for "Victory Ship", the small tankers Rijo and Raza for transportation of gasoline, transferred by the USAF to the FAB and then to To MB, and finally, three high-sea tugs of the "Tristan" class, former class "Ata" of the US Navy.
During the administration of Admiral Renato Guillobel (1951-1954) a large program of media acquisition was created for auxiliary tasks of the Navy. Through it were acquired 10 corvettes (class "Imperial Mariner" of coastal patrol in Holland, capable of also operating as tugboats of the high seas and mining ships).
Four troop-carrying ships were also acquired in Japan, capable of operating as cargo ships in commercial cargo transport and logistical support, and two modern hydrofoil vessels, Sirius and Canopus, which together with the 3 small "Argus" , Built in the Arsenal of the Navy of Rio de Janeiro (AMRJ), came to give extraordinary impetus to the hydrographic activities of the country.
From 1959, the Navy of Brazil began to receive from the U.S. Navy reserve, destroyers of the class "Fletcher", in a total of 7 ships.
Then came 5 destroyers of the class "Allen M. Sumner" and finally 2 of class "Gearing", the great majority received during the administration of Admiral Adalberto Nunes (1970-74).
From 1957 a total of 11 U.S. submarines were received. Navy, being 4 units "Fleet Type", 5 units class "Guppy II" and 2 units "Guppy III".
