War of Independence

The Brazilian Navy came into being with the independence of the country. Some of its members were native-born Brazilians, who under Portuguese rule had been forbidden to serve, while other members were Portuguese born who adhered to the cause of independence and foreign mercenaries. A number of establishments previously created by King João VI of Portugal were incorporated into the navy such as the Department of Navy, Headquarters of the Navy, the Intendancy and Accounting Department, the Arsenal (Shipyard) of the Navy, the Academy of Navy Guards, the Naval Hospital, the Auditorship, the Supreme Military Council, the powder plant, and others. The Brazilian-born Captain Luís da Cunha Moreira was chosen as the first minister of the Navy on 28 October 1822.^[3][4]

British naval officer Lord Thomas Alexander Cochrane was made the commander of the Brazilian Navy and received the rank of "First Admiral".^[5][6] At that time, the fleet was composed of one ship of the line (Pedro I), four frigates, and smaller ships for a total of 38 warships. The Secretary of Treasury Martim Francisco Ribeiro de Andrada created a national subscription to generate capital in order to increase the size of the fleet. Contributions were sent from all over Brazil. Even Emperor Pedro I acquired a merchant brig at his own expense (renamed Caboclo) and donated it to the Navy.^[6][7] The navy fought in the north and also south of Brazil where it had a decisive role in the independence of the country.^[8] After the suppression of the revolt in Pernambuco in 1824 and prior to the Cisplatine War, the navy increased significantly in size and strength. Starting with 38 ships in 1822, eventually the navy had 96 modern warships of various types with over 690 cannon.

Cisplatine War and rebellions (1825–1849)

The Navy blocked the estuary of the Río de la Plata hindering the contact of the United Provinces (as Argentina was then called) with the Cisplatine rebels who wanted Uruguay to join Argentina again or become an independent country, and the outside world. Several battles had occurred between Brazilian and Argentine ships, with Irish-born Argentine admiral William Brown temporarily leading a successful campaign, which had included a significant victory at Juncal. Eventually however, a Brazilian fleet led by English admiral James Norton scored a decisive victory near the island of Santiago in mid 1827, rendering the United Provinces navy combat ineffective and ensuring that the blockade would proceed uncontested. The war came to a stalemate and in 1828, Brazil accepted the resolution guaranteeing the independence of Uruguay. When Pedro I abdicated in 1831, he left a powerful navy made up of two ships of the line and ten frigates in addition to corvettes, steamships, and other ships for a total of at least 80 warships in peacetime.^[9][10] During the 58-year reign of Pedro II the Brazilian Navy achieved its greatest strength in relation to navies around the world.^[11] The Arsenal, Navy department, and the Naval Jail were improved, and the Imperial Marine Corps was created. Steam navigation was adopted. Brazil quickly modernized its fleet acquiring ships from foreign sources while also constructing ships locally. Brazil's Navy substituted the old smoothbore cannon for new ones with rifled barrels, which were more accurate and had longer ranges. Improvements were also made in the Arsenals (shipyards) and naval bases, which were equipped with new workshops.^[10] Ships were constructed in the Naval Arsenal of Rio de Janeiro, Salvador, Recife, Santos, Niterói and Pelotas. The Navy also successfully fought against all revolts that occurred during the Regency where it conducted blockades and transported the Army troops; including Cabanagem, Ragamuffin War, Sabinada, Balaiada, amongst others.^[10][12]

When Emperor Pedro II was declared of legal age and assumed his constitutional prerogatives in 1840, the Armada had over 90 warships: six frigates, seven corvettes, two barque-schooners, six brigs, eight brig-schooners, 16 gunboats, 12 schooners, seven armed brigantine-schooners, six steam barques, three transport ships, two armed luggers, two cutters and thirteen larger boats.^[13]

During the 1850s the State Secretary, the Accounting Department of the Navy, the Headquarters of the Navy and the Naval Academy were reorganized and improved. New ships were purchased, and the ports administrations were better equipped. The Imperial Mariner Corps was definitively regularized, and the Marine Corps was created, taking the place of the Naval Artillery. The Service of Assistance for Invalids was also established, along with several schools for sailors and craftsmen.^[14]

Platine & Paraguayan wars (1849–1870)

The conflicts in the Platine region did not cease after the war of 1825. The anarchy caused by the despotic Rosas and his desire to subdue Bolívia, Uruguay and Paraguay forced Brazil to intercede. The Brazilian Government sent a naval force of 17 warships (a ship of the line, 10 corvettes and six steamships) commanded by the veteran John Pascoe Grenfell.^[15] The Brazilian fleet succeeded in passing through the Argentine line of defence at the Tonelero Pass under heavy attack and transported the troops to the theater of operations. The Brazilian Armada had a total of 59 vessels of various types in 1851: 36-armed sailing ships, 10 armed steamships, seven unarmed sailing ships and six sailing transports.^[16] More than a decade later the Armada was once again modernized, and its fleet of old sailing ships was converted to a fleet of 40 steamships armed with more than 250 cannons.^[17] In 1864 the navy fought in the Uruguayan War and immediately afterwards in the Paraguayan War where it annihilated the Paraguayan navy in the Battle of Riachuelo. The navy was further augmented with the acquisition of 20 ironclads and six fluvial monitors. At least 9,177 navy personnel fought in the five years' conflict.^[18] Brazilian naval constructors such as Napoleão Level, Trajano de Carvalho and João Cândido Brasil planned new concepts for warships that allowed the country's Arsenals to retain their competitiveness with other nations.^[19] All damage suffered by ships was repaired and various improvements were made to them.^[20] In 1870, Brazil had 94 modern warships^[21] and had the fifth most powerful navy in the world.^[22]

Expansion and the end of the Empire (1870–1889)

During the 1870s, the Brazilian Government strengthened the navy as the possibility of a war against Argentina over Paraguay's future became quite real. Thus, it acquired a gunboat and a corvette in 1873; an ironclad and a monitor in 1874; and immediately afterwards two cruisers and another monitor.^[8][23] The improvement of the Armada continued during the 1880s. The Arsenals of the Navy in the provinces of Rio de Janeiro, Bahia, Pernambuco, Pará and Mato Grosso continued to build dozens of warships. Also, four torpedo boats were purchased.^[24] On November 30, 1883, the Practical School of Torpedoes was created along with a workshop devoted to constructing and repairing torpedoes and electric devices in the Arsenal of Navy of Rio de Janeiro.^[25] This Arsenal constructed four steam gunboats and one schooner, all with iron and steel hulls (the first of these categories constructed in the country).^[24] The Imperial Armada reached its apex with the incorporation of the ironclad battleships Riachuelo and Aquidabã (both equipped with torpedo launchers) in 1884 and 1885, respectively. Both ships (considered state-of-the-art by experts from Europe) allowed the Brazilian Armada to retain its position as one of the most powerful naval forces.^[26] By 1889, the navy had 60 warships^[20] and was the fifth or sixth most powerful navy in the world.^[27]

In the last cabinet of the monarchic regime, the Minister of the Navy, Admiral José da Costa Azevedo (the Baron of Ladário), left the reorganization and modernization of the navy unfinished.^[20] The coup that ended the monarchy in Brazil in 1889 was not well accepted by the Armada. Imperial Mariners were attacked when they tried to support the imprisoned Emperor in the City Palace. The Marquis of Tamandaré begged Pedro II to allow him to fight back the coup; however, the Emperor refused to allow any bloodshed.^[28] Tamandaré would later be imprisoned by order of the dictator Floriano Peixoto under the accusation of financing the monarchist military in the Federalist Revolution.^[29]

The Baron of Ladário remained in contact with the exiled Imperial Family, hoping to restore the monarchy, but ended up ostracized by the republican government. Admiral Saldanha da Gama led the Revolt of the Armada with the objective of restoring the Empire and allied himself with other monarchists who were fighting in the Federalist Revolution. However, all the attempts at restoration were violently crushed. High-ranking Monarchist officers were imprisoned, banished or executed by firing squad without due process of law and their subordinates also suffered harsh punishments.^[30]

Naval revolts

The military coup that led to the proclamation of the Brazilian Republic (1889), accentuated the decline of shipbuilding in the country. For four decades, between 1890 and 1930 no new ships were built in Brazil. The focus of republican governments was to equip the army to fight internal uprisings in the new regime's early years. The Navy was perceived as a threat to the new republican regime, as it had been more loyal to the Monarchy.

The situation became precarious in just over a decade as the Naval Battalion was reduced to 295 soldiers and Imperial Marines to 1,904 men. The equipment and vessels acquired were considered outdated by Navy officials, who criticized the abandonment of repair shops. Naval officers participated in two riots, known as Naval Riots. The second, avowedly monarchist, cost the officers their careers and their lives, without entering the military justice process. The sailors who obeyed orders and took part in the attempt to restore monarchy suffered cruelly.^[31]

South American naval rivalry

Brazil's navy fell into disrepair and obsolescence in the aftermath of the 1889 revolution, which deposed Emperor Pedro II, after naval officers led a revolt in 1893–94.^[32] Meanwhile, the Argentine and Chilean navies were flush with modern warships after the conclusion of a naval arms race between the two.^[33] As a result, at the turn of the 20th century the Brazilian Navy lagged far behind its Argentine and Chilean counterparts in quality and total tonnage.^[34]

Rising demand for coffee and rubber brought Brazil an influx of revenue in the early 1900s.^[35] Simultaneously, there was a drive on the part of prominent Brazilians, most notably Pinheiro Machado and the Baron of Rio Branco, to have the country recognized as an international power. A strong navy was seen as crucial to this goal.^[36] The National Congress of Brazil drew up and passed a large naval acquisition program in late 1904, but it was two years the Minister of the Navy, Admiral Júlio César de Noronha, signed a contract with Armstrong Whitworth for three small battleships.^[37]

Battleship Minas Gerais (1910–1952)

After construction began, a new presidential administration took office, and the new government reconsidered their chosen battleship design. This was wrought by the debut of the United Kingdom's new dreadnought concept, especially its "all-big-gun" armament that utilized many more heavy-caliber weapons than previous battleships. This warship type would have rendered the Brazilian ships obsolete before they were completed.^[38]

As a result, the Brazilian government redirected its naval funds towards three dreadnoughts, of which only two would be built immediately.^[39] This move was made with the large-scale support of Brazilian politicians, including Pinheiro Machado and a nearly unanimous vote in the Senate; the navy, now with the large-ship advocate Rear Admiral Alexandrino Faria de Alencar in the influential post of minister of the navy; and the Brazilian press.^[40] It made Brazil was the third country to have a dreadnought under construction, behind the United Kingdom and the United States, and before France, the German Empire, the Russian Empire, and the Empire of Japan.^[41] As dreadnoughts were quickly equated with international status, somewhat similar to nuclear weapons today—that is, regardless of a state's need for such equipment, simply ordering and possessing a dreadnought increased the owner's prestige—the order caused a stir in international relations.^[42]

This order led to a naval arms race between Brazil, Argentina, and Chile, which was ended only by the advent of the First World War. Brazil's first two dreadnoughts, Minas Geraes and São Paulo, would be delivered in 1910. The third dreadnought was redesigned multiple times in response to advancing naval technology and financial concerns; it would eventually be sold to the Ottoman Empire and serve with the British as HMS Agincourt. A larger super-dreadnought was ordered shortly before the war, but little was accomplished prior to the beginning of the conflict.^[43]

Revolt of the Lash

In late 1910, a major rebellion known as the Revolt of the Lash, or Revolta da Chibata, broke out on four of the newest ships in the Brazilian Navy. The initial spark was provided on 21 November when Afro-Brazilian sailor Marcelino Rodrigues Menezes was brutally flogged 250 times for insubordination. Many Afro-Brazilian sailors were sons of former slaves, or were former slaves freed under the Lei Áurea (abolition) but forced to enter the navy. They had been planning a revolt for some time, and Menezes became the catalyst. Further preparations were needed, so the rebellion was delayed until 22 November. The crewmen of Minas Geraes, São Paulo, the twelve-year-old Deodoro, and the new Bahia quickly took their vessels with only a minimum of bloodshed: two officers on Minas Geraes and one each on São Paulo and Bahia were killed.^[44]

The ships were well-supplied with foodstuffs, ammunition, and coal, and the only demand of mutineers—led by João Cândido Felisberto—was the abolition of "slavery as practiced by the Brazilian Navy". They objected to low pay, long hours, inadequate training for incompetent sailors, and punishments including bôlo (being struck on the hand with a ferrule) and the use of whips or lashes (chibata), which eventually became a symbol of the revolt. By 23 November, the National Congress had begun discussing the possibility of a general amnesty for the sailors. Senator Ruy Barbosa, long an opponent of slavery, lent a large amount of support, and the measure unanimously passed the Federal Senate on 24 November. The measure was then sent to the Chamber of Deputies.^[45]

Humiliated by the revolt, naval officers and the president of Brazil were staunchly opposed to amnesty, so they quickly began planning to assault the rebel ships. The former believed such an action was necessary to restore the service's honor. Late on 24 November, the President ordered the naval officers to attack the mutineers. Officers crewed some smaller warships and the cruiser Rio Grande do Sul, Bahia's sister ship with ten 4.7-inch (119 mm) guns. They planned to attack on the morning of 25 November, when the government expected that the mutineers would return to Guanabara Bay. When they did not return and the amnesty measure neared passage in the Chamber of Deputies, the order was rescinded. After the bill passed 125–23 and the president signed it into law, the mutineers stood down on 26 November.^[46]

Lobster War (1961–1963)

Brazilian Navy cruiser Tamandaré flagship in task force, Lobster War

In 1961, some groups of French fishermen who were operating very profitably off the coast of Mauritania extended their search to the other side of the Atlantic Ocean, settling on a spot off the coast of Brazil where lobsters are found on submerged ledges at depths of 250–650 ft (76–198 m). Local fishermen complained that large boats were coming from France to catch lobster off the state of Pernambuco, so the Brazilian Admiral Arnoldo Toscano ordered two corvettes to sail to the area where the French fishing boats were located. Seeing that the fishermen's claim was justifiable, the captain of the Brazilian vessel then demanded that the French boats retreat to deeper water, leaving the continental shelf to smaller Brazilian vessels. The situation became very tense once the French rejected this demand and radioed a message asking for the French government to send a destroyer to accompany the lobster boats, which prompted the Brazilian government to put fleet in a state of alert.

The French Government dispatched a T 53-class destroyer on 21 February to watch over the French fishing boats. The French vessel withdrew after the arrival of a Brazilian warship and the aircraft carrier Minas Gerais.

1964 Coup d'état

Although corporal punishment was officially abolished after the Revolt of the Lash, or Revolta da Chibata, at the end of 1910, improvement in working conditions and career plans were still contentious in early 1960. The dissatisfaction with officialdom and conservative politicians, coupled with the lack of vision and inability of the general policy of then president João Goulart, led the sailors, encouraged by leaders such as Corporal Anselmo, to the military coup of 1964.

The purges carried out later (not just the navy but for all the armed forces), and the establishment of certain criteria for selection of its new members were a military term in the Brazilian tradition among its members openly harboring various currents of political thought.

The Colossus-class aircraft carrier Minas Gerais served the Navy until its decommissioning in 2001.

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

AFF447 (2009)

The corvette Caboclo was the first in Brazilian Navy vessel in the searches of the Air France Flight 447, the vessel was patrolling waters near the site of the aircraft's disappearance

Flight 447 was due to pass from Brazilian airspace into Senegalese airspace at approximately 02:20 (UTC) on 1 June, and then into Cape Verdean airspace at approximately 03:45. Shortly after 04:00, when the flight had failed to contact air traffic control in either Senegal or Cape Verde, the controller in Senegal attempted to contact the aircraft. When he received no response, he asked the crew of another Air France flight (AF459) to try to contact AF447; this also met with no success.^[54]

The Brazilian Navy also moved three vessels initially, being the patrol vessel Grajaú, the frigate Constituição and the corvette Caboclo to aid in the searches. Subsequently, the tanker Almirante Gastão Motta and the frigate Bosisio were sent, increasing the search force of the navy to five boats.

During the search period, 51 bodies were recovered, more than 600 pieces of the aircraft, as well as passengers' luggage. A total of 1,344 officers of the Brazilian Navy and eleven vessels, 35,000 miles, were directly involved in the search, rescue and support.^[55]

ARA San Juan (2017)

On 15 November 2017, the submarine San Juan in service with the Argentine Navy, stopped communicating during a routine patrol in the South Atlantic off the coast of Argentina. A multi-nation search operation was mounted to try to locate the submarine, which was believed to have suffered an electrical malfunction. Within hours of San Juan's last transmission, reports describe an explosive noise, detected in the vicinity of the vessel's last known location.

The frigate Rademaker, the submarine relief ship NSS Felinto Perry and the polar ship NPo Almirante Maximiano of the Brazilian Navy participated in the multinational search for the lost submarine.^[56]

Haiti

The frigate Bosísio was one of the Brazilian Navy warships sent on a UN mission in Haiti

On 28 May 2004 four Brazilian Navy ships (Mattoso Maia, Rio de Janeiro, Almirante Gastão Motta, Bosísio) departed from Rio de Janeiro bound for Haiti on a peace mission coordinated by the United Nations (UN). The ships transported part of the military contingent involved in Haitian reconstruction. In addition to 150 Marines and Army troops, the ships carried most of the material for the Brazilian stabilization force — approximately 120 vehicles, 26 trailers of various types, and 81 containers loaded with equipment and supplies.^[57] On 28 February 2010, the Brazilian Navy ship Garcia D'Avila sailed from Rio de Janeiro with 900 tons of cargo, including humanitarian aid supplies to earthquake victims in Haiti as well as equipment for the Brazilian military that operates in that country.

Ammunition was brought for Brazilian soldiers in addition to 14 power generators and 30 vehicles, including trucks, ambulances, and armored vehicles. The ship's crew consisted of 350 mariners.^[58]

Lebanon

On 15 February 2011, Brazil assumed command of the Maritime Task Force (MTF) of the United Nations Interim Force in Lebanon (UNIFIL).^[59] On 4 October, the Brazilian Ministries of Defence and Foreign Relations informed authorities that Brazil was sending a Navy vessel with up to 300 crew members equipped with an aircraft to join the fleet in Lebanon, and the National Congress authorized the ship.^[60] On 25 November 2011 the frigate União with 239 officers and sailors aboard joined the task force, bringing to nine the number of vessels assisting the Lebanese Navy in monitoring Lebanese territorial waters. The frigate served as the flagship for Rear Admiral Luiz Henrique Caroli of Brazil, who had been Commander of UNIFIL-MTF since February.^[61]

On 10 April 2012, the frigate Liberal left Rio de Janeiro bound for Lebanon to join the force.^[62] It was relieved in January 2013 by the frigate Constituição which joined a multinational group comprising nine ships; three from Germany, two from Bangladesh, one from Greece, one from Indonesia and one from Turkey. The crew comprised 250 military officials. The return to Rio was scheduled for August 2013.^[63]

On 8 August 2015, the corvette Barroso left Rio de Janeiro to replace União and later that month carried out maritime interdiction operations and provided training to the Lebanese Navy.^[64] On 4 September 2015 it rescued 220 Syrian migrants in the Mediterranean Sea, as reported by the Ministry of Defense in a statement released on its website. The Brazilian ship was sailing towards Beirut in Lebanon when it received an alert from the Italian Maritime Rescue Coordination Centre (MRCC) about a sinking vessel taking immigrants to Europe.^[64]

Combined Task Force 151

On June 9, 2021, the Brazilian Navy assumed command of the Combined Task Force (CTF) 151, a multinational task force to combat piracy and which protects the global maritime trade in an area covering the Arabian Sea, Gulf of Oman, Gulf of Aden, Somali coast and southern Red Sea.^[65]
