In Development by Itaguaí, a Naval Construction Company (ICN), the Ships Designed for the Navy’s Submarine Development Program (PROSUB) Are in Their Final Stages

As far as is known at present, the Navy’s Submarines (PROSUB) from the Brazilian Navy (MB) are already divided into 05 main sections, namely: S1, S2A, S2B, S3, and S. Furthermore, the special highlight of today’s information will be focused solely on sections S1 and S2A.

In summary, section S1 is located at the end of the submarine. It is precisely what will determine the direction and stabilized depth limits throughout navigation on the seabed. Undoubtedly, a modern strategy of naval construction.

Thus, an important item for the energy conversion of the PROSUB submarine has also been placed at the end of the submarine – a propeller shaft for better and quieter movement.

In this section of the PROSUB submarine being developed by Itaguaí, the diesel compartments and another 04 engines that serve as a kind of charger for the batteries are located.

Finally, in 2019, there were also advances involving naval construction in PROSUB. With the completion of acceptance tests at the dock and the successful static submersion, which marked the beginning of at-sea acceptance tests for the “Riachuelo” Submarine. Undoubtedly, the first of the four vessels with diesel-electric propulsion planned in the aforementioned Program. The Brazilian naval construction has invested billions.

About the Navy’s Submarine Development Program (PROSUB)

In summary, the Submarine Development Program (PROSUB) of the Brazilian Navy is the result of a technology transfer agreement with the French company Naval Group (formerly DCNS). Signed in 2008 by Brazil and France, it will enable the production of four Scorpène-class conventional submarines. It will also assist in the manufacturing of the first Brazilian nuclear-powered submarine (SN-BR).

About the Navy’s Submarine Development Program (PROSUB)

The Soviet Union spent 22 years drilling into the Earth’s crust and reached a depth of 12,262 meters — they found water where it was thought impossible, hydrogen bubbling from the rock, granite that is 2.7 billion years old, and temperatures of 180 degrees that melted the drill bits.

Egypt wants to draw 10 million cubic meters of water from the Nile per day into the desert, irrigate a new agricultural frontier, and build a city where there is currently only sand.

Norway is drilling 27 kilometers of rock 392 meters below the bottom of a fjord to build the world’s largest and deepest underwater road tunnel — when completed, a 21-hour journey will be reduced to 10.

Chinese engineers begin filling a 217-meter dam at an altitude of 3,000 meters and prepare a 2,240 MW hydroelectric power plant to integrate hydropower, solar, and wind energy in the upper Jinsha.

A German architect built a cylindrical house in 1994 that rotates to follow the sun throughout the day, generates 5 times more energy than it consumes, and was the world’s first energy-positive house.

An astronaut spent 340 days in space while his twin brother stayed on Earth, and NASA found a “rejuvenating” effect, genes, microbiome, cognition, and immune system that revealed the biological cost of living outside the planet.

After mapping more than 200 million proteins, artificial intelligence enters the race to accelerate drugs, vaccines, and enzymes against plastic and CO₂, opening an era in which molecules can be designed on demand.

Sleeping in the coldest city in Brazil seemed like just another camping challenge, until the rain intensified, the hail fell, the meal failed, and the cold turned the night into a test of endurance.

A particle smaller than a human hair accelerates with light and promises to transform ocean uranium extraction into a giant bet to power China’s nuclear reactors without relying solely on the old passive collection method.

Pirates chose this beach on the coast of São Paulo as a hideout centuries ago, and visitors today understand why when they see the greenish sea, the animal-shaped rocks, and the natural aquarium.

An impressive Russian road crosses 968 km between rivers, glaciers, and Altai mountains, following a Bronze Age route that connects Siberia to the border with Mongolia.
