Era 1 1763 to 1821
The shipyard and the academy
The Crown decides to build ships in the colony. With the court, in 1808, come the academy, the pharmacy and the shipboard troops.
Driven by the gold of Minas Gerais and by conflicts in the South, the Portuguese Crown founds the Royal Navy Arsenal in 1763 at the foot of São Bento Monastery in Rio de Janeiro. Four years later the yard launches its first ship, the São Sebastião.
The court's move to Brazil in 1808 brings three seeds that last for centuries: the Royal Academy of Midshipmen, founded in Lisbon in 1782 to teach mathematics and navigation sciences; the Military Pharmacy, origin of the Pharmaceutical Laboratory; and the Royal Navy Brigade, the starting point of the Marine Corps.
That same year the Navy Ministry is set up, with a hospital, an archive and a gunpowder factory, and the Arsenal takes on the support of the newly arrived fleet.
Why it matters. Building, teaching and caring: the three callings the Navy still holds today all begin in this era.

Milestones 8
1763
The Royal Navy Arsenal is founded
The Count of Cunha founds the shipyard at the foot of São Bento Monastery in Rio de Janeiro. It is the origin of today's Navy Arsenal and of the practice of designing and building ships in Brazil.
1767
The ship of the line São Sebastião is launched
The first ship built by the Royal Arsenal, the São Sebastião, known as the “Serpent”, is launched four years after the yard was founded.
1782
The Royal Academy of Midshipmen is founded
Queen Maria I founds in Lisbon the academy that trains future Portuguese naval officers, with a curriculum of mathematics and sciences applied to navigation.

The Academy of Midshipmen arrives in Rio
The Academy crosses the Atlantic with the court, bringing students, teachers and records, and settles in São Bento Monastery until the 1830s. It moves to Villegagnon Island in 1938 as the Naval School.
1808
The Arsenal takes on the fleet's support
With the court's arrival, the Royal Arsenal is enlarged to support the fleet and, renamed the Court Navy Arsenal, takes charge of the Navy's funds and supplies in Brazil.
1808
The Royal Navy Brigade lands in Rio
Created in 1797, the brigade arrives with the royal court, sets up at the São José Fortress on Cobras Island and guards Navy facilities ashore. The date marks the birth of the Brazilian Marine Corps.
1808
The Navy Ministry is set up in Rio
The Ministry of Navy and Overseas Affairs is established in Rio. It is followed by the Fleet Headquarters, the Military Archive, the Navy Hospital and the Gunpowder Factory.
1808
The Military Pharmacy is created
A decree creates the pharmacy and places it under apothecary Joaquim José Carvalho. It is the origin of today's Navy Pharmaceutical Laboratory.

In the Showcase today
Institutes rooted in this era and what they offer now.
Era 2 1822 to 1889
The imperial science of the sea
The Empire learns to chart its own coast and takes the Navy into international science.
The Empire inherits Portuguese and French charts. From 1830, Brazilian officers survey the coast themselves; Vital de Oliveira charts the northeastern shore, and Hoonholtz, the future Baron of Teffé, writes the Compendium of Hydrography used at the Academy.
During the War of the Triple Alliance, Brazilian engineers design and build ironclads at the Court Arsenal. In 1876 the Hydrographic Office is created under Teffé, who in 1882 leads the Brazilian team observing the Transit of Venus.
In 1888 the Navy Ministry gains the Central Meteorological Office, the Empire's center for meteorology and terrestrial physics, which issues weather warnings to ports.
Why it matters. This is the birth of ocean science as a state service, in a direct line to the DHN and today's Navy Hydrographic Center.

I am a hydrographer in time of peace, but in time of war I claim my standing as a combat officer, and I therefore hasten to request Your Excellency's permission to take the ship under my command to the port of Rio de Janeiro to complete her guns and munitions, and then sail for the River Plate to join the Division in operations.

1830s
Brazilian officers draw the first charts
From 1830 on, Navy officers begin surveying the coast themselves. Until then, navigation relied on Portuguese and French charts, notably those by Mouchez.
1840
The pharmacy moves into the hospital
Decree No. 58 attaches the Military Pharmacy to the Army and Navy Hospital.
1850 to 1867
Vital de Oliveira surveys the northeastern coast
In the 1850s and 1860s, Manoel Antônio Vital de Oliveira surveys the coast from Rio Grande do Norte to Alagoas, producing five charts and sailing directions. He is the patron of Brazilian hydrography.

Hydrographic survey of Guanabara Bay
Serving as aide to the future Viscount of Lamare, young officer Antônio Luís von Hoonholtz, later Baron of Teffé, carries out one of the Navy's first hydrographic surveys.
1859
The Compendium of Hydrography is published
Hoonholtz publishes his Compendium of Hydrography, regarded as the first Portuguese-language work on the subject adopted by the Navy Academy.
1865 to 1866
Ironclads designed and built at the Arsenal
During the War of the Triple Alliance, Brazilian engineers such as Napoleão Level and Carlos Braconnot design and build armored warships at the Court Arsenal. The Tamandaré is among the first three.

Era 3 1889 to 1945
New technologies of the Republic
Radio, submarines and aircraft reach the Navy early, but its ships still arrive ready-made from abroad.
The Navy is an early adopter of the technologies changing warfare: wireless telegraphy in 1904, submarines in 1914 and, in 1916, the country's first military flying school. Education grows with the Higher Naval Course (1911) and the Naval War School (1914).
Ships, however, still come ready-made from foreign yards. The Arsenal is modernized on Cobras Island only around 1930. In the 1930s hydrography becomes an institution, Brazil prints its first nautical chart (1933) and the Naval Institute of Biology is created (1934).
The creation of the Air Ministry in 1941 takes away the Navy's air arm and closes the era.
Why it matters. It reveals the tension between adopting technology and mastering it, which drives the rest of this history.

Era 4 1946 to 1969
Science as state policy
The postwar years convince the Navy that it needs its own laboratory and a national science policy.
In 1947 Admiral Álvaro Alberto takes a proposal for an atomic program to the government, and he conceives the CNPq, created in 1951 with him as president. In 1954 he negotiates three German ultracentrifuges, whose shipment is blocked by the Allied occupation authorities.
In 1953 Admiral Paulo Nogueira Penido proposes a research laboratory. The cornerstone is laid in 1955 and IPqM is born in 1959, with marine biology and oceanography alongside weapons and electronics. Robert Oppenheimer visits in 1961.
In 1956 Paulo Moreira identifies the Cabo Frio upwelling as a source of food from the sea. The pharmacy becomes the Pharmaceutical Laboratory in 1958.
Why it matters. It produces the Navy's first R&D center and an explicit bridge between the Navy, national science and nuclear energy.

The export, in any form, of uranium and thorium and their compounds and ores is prohibited, except from government to government, after consultation with the competent bodies.
Milestones 12
1947
A national atomic program is approved
The National Security Council approves Admiral Álvaro Alberto's proposal, sent from New York, for a national atomic energy program.
1951
The National Research Council is created
Law No. 1,310 creates the CNPq, conceived and first chaired by Admiral Álvaro Alberto. The law bans exports of uranium and thorium except between governments.
1953
A Navy research laboratory is proposed
In Letter No. 1204, Director-General of Electronics Admiral Paulo Nogueira Penido proposes to the Navy Minister the creation of a research laboratory.
1954
Three ultracentrifuges are bought in Germany
In secret talks led by Álvaro Alberto, Brazil buys three ultracentrifuges in West Germany. The Allied occupation authorities, under US pressure, block their shipment.
1955
IPqM's cornerstone is laid
The cornerstone is laid at Ponta do Matoso, on Governador Island, with Álvaro Alberto present. The building is designed by architects Hélio Queiroz Duarte and Ernest Mange.
1956
Paulo Moreira points to the Cabo Frio upwelling
Lieutenant Commander Paulo Moreira identifies the Cabo Frio area, where cold, nutrient-rich water wells up, as a promising place to produce protein from the sea.

Era 5 1970 to 1989
Frigates, computers and the sea
A digital frigate program pulls along a computer, a company and a research center. The same period creates most of today's institutes.
The Niterói frigates, the Navy's first ships with digital weapon and sensor systems, lead to three offshoots: the working group behind the G-10 computer and COBRA (1974), CASNAV (1975), created to evaluate them, and the building of two of them at the Rio Navy Arsenal. The Naval Engineering Directorate designs the Inhaúma corvettes.
The Navy Nuclear Program begins in 1979 within the autonomous program known as the parallel program. It gains COPESP in 1986, sees mastery of enrichment announced in 1987 and opens Aramar in 1988. The 1988 Constitution limits nuclear activity to peaceful purposes.
The Cabo Frio Project becomes INEM (1984), today's IEAPM. Brazil reaches Antarctica (1982 and 1984) and begins surveying its own continental shelf (1987).
Why it matters. This is the era of import substitution in sensitive technology, with the Navy as the customer that drives industry.

Era 6 1990 to 2007
The Blue Amazon
The focus of naval science shifts from the ship to the maritime territory.
Law 8,617 (1993) and the entry into force of the Law of the Sea Convention for Brazil (1994) give the maritime territory a legal basis. In 2004 the country submits its continental shelf outer limit to the UN, and the Navy Commander coins the term Blue Amazon.
CASNAV starts providing S&T services (1997), fixed-wing aviation returns (1998), the Hydrographic Center is created (1998) and a research station begins operating on the São Pedro and São Paulo Archipelago.
Brazil creates ABACC with Argentina (1991) and joins the NPT (1998). On a tight budget, the nuclear program brings its centrifuges to industry at Resende (2006) and is revived in 2007.
Why it matters. It gives this history its central argument: ocean science is sovereignty, which is why hydrography, ocean data and maritime surveillance are S&T subjects.

Era 7 2008 to 2026
An S&T system and industrial sovereignty
From three isolated institutes to a system of 18, as submarines, missiles and frigates come to be built in Brazil.
The Navy S&T Secretariat is created in 2008 with three institutes, becomes a sectoral directorate in 2012 and DGDNTM in 2016, taking over PROSUB and the Nuclear Program. NIT-MB (2009), AMAZUL (2012) and CTMRJ (2016) follow. By 2026 the system has 18 institutions.
The agreement with France (2008) creates PROSUB: Riachuelo is launched in 2018 and all four conventional submarines are afloat by 2025. The nuclear-powered submarine is in detailed design. MANSUP has flown since 2018, and the frigate Tamandaré is commissioned in 2026.
The UN approves the extended shelf of the Southern Region (2019) and of the Equatorial Margin (2025), and the new Ferraz Station opens in 2020.
