Construction of Conventional Diesel-Electric Submarines

As part of the PROSUB program, Brazil is constructing four conventional diesel-electric submarines based on the French Scorpène-class design. These submarines, designated as the Riachuelo-class, represent a significant upgrade to Brazil's existing submarine fleet. The first submarine of this class, the Riachuelo, was launched in 2018 and commissioned in 2022. The remaining three submarines are in various stages of construction, with planned commissioning dates in the coming years. These conventional submarines will enhance Brazil's ability to patrol its vast coastline, protect its maritime resources, and project power in the South Atlantic.

The Riachuelo-class submarines are equipped with advanced sensors, weapons, and communication systems, making them highly capable platforms for a variety of missions. They are designed for anti-surface warfare, anti-submarine warfare, intelligence gathering, and special operations. The submarines are also equipped with air-independent propulsion (AIP) systems, which allow them to remain submerged for longer periods, increasing their operational effectiveness. The construction of these submarines in Brazil is a testament to the success of the technology transfer component of the PROSUB program. Brazilian engineers and technicians are playing a key role in the construction process, gaining valuable experience and expertise.

Development of a Nuclear-Powered Submarine

The centerpiece of the PROSUB program is the development of a nuclear-powered submarine, which will be the first of its kind in the Southern Hemisphere. This submarine, tentatively named Álvaro Alberto, represents a major leap in Brazil's naval capabilities and a significant achievement for its defense industry. The development of the nuclear submarine is a complex and challenging undertaking, requiring significant investment in infrastructure, technology, and human resources.

Brazil is working closely with France to develop the nuclear reactor that will power the submarine. The reactor is being designed to meet the highest safety standards and will be fueled by low-enriched uranium. The submarine will be equipped with advanced sensors, weapons, and communication systems, making it a formidable platform for a variety of missions. It will be capable of operating at greater depths and for longer durations than conventional submarines, giving Brazil a significant strategic advantage in the South Atlantic. The Álvaro Alberto is expected to be commissioned in the late 2030s, marking a new era for the Brazilian Navy.

Construction of a New Submarine Base and Shipyard

To support the construction and maintenance of the submarines, Brazil is building a new submarine base and shipyard in Itaguaí, Rio de Janeiro. This facility, known as the Itaguaí Naval Complex, is one of the largest and most modern naval complexes in Latin America. It includes a shipyard for the construction of submarines, a naval base for the berthing and maintenance of submarines, and a training center for submarine crews. The Itaguaí Naval Complex is a key component of the PROSUB program, providing the infrastructure necessary to support Brazil's growing submarine fleet.

The construction of the Itaguaí Naval Complex has created thousands of jobs and has stimulated economic growth in the region. The complex is equipped with state-of-the-art equipment and technology, making it a world-class facility.
