The Transfer Made by the Navy of the Submarine to the Itaguaí Shipyard Will Happen in Three Stages, the Last of Which Will Take Place at the Beginning of May

The Brazilian Navy has reached another important milestone in the Submarine Development Program (Prosub), with the conclusion of the transfer of the first section of the Angostura submarine (S-43) to the Construction Shipyard, located in the Naval Complex of Itaguaí, in the Metropolitan Region of Rio de Janeiro, according to the Petronotícias website.

The transfer at the shipyard by the Navy will be carried out in three stages, with the first section, known as the Stern, responsible for housing the electric propulsion motor, vertical and horizontal fin systems, propeller shaft, and propeller. The second section of the shipyard transfer will take place at the end of April, and the last section will be moved in early May.

Technical Competence of the Brazilian Industry in the Construction of Submarines at the Shipyard

The Navy emphasized the technical competence of the Brazilian industry in the construction of Riachuelo class submarines, with the download operation of the sections from the Angostura shipyard improved since the download of the Riachuelo sections in 2017. This process requires detailed planning, from the evolution of segments of the electrical network to traffic management on BR-493, coordinated with various agencies to ensure safety and avoid disruption to local urban mobility, according to the Navy.

Nuclep and the Construction of Brazilian Submarines

Nuclep, a Brazilian company, is responsible for building the hulls of the four conventional submarines of Prosub: Riachuelo, Humaitá, Tonelero, and Angostura. The company is also one of the participants in the construction of Brazil’s first nuclear propulsion submarine, the Submarine Almirante Álvaro Alberto.

“The arrival of the first section of the Angostura submarine at the Construction Shipyard in Itaguaí is a significant milestone for the Navy’s Submarine Program. This is the fourth conventional diesel-electric submarine of Prosub, whose hulls were built by Nuclep. This is an important milestone for the Navy that demonstrates Brazilian technological capacity in submarine construction. Nuclep feels very proud to be part of Prosub”, said the president of Nuclep, Carlos Seixas.

Prosub is a strategic program of the Brazilian Navy aimed at the development of conventional and nuclear propulsion submarines, seeking national autonomy in the construction of these vessels and strengthening the country’s defense capabilities at shipyards. The transfer of the first section of the Angostura submarine to the Construction Shipyard in Itaguaí represents another advance in this Navy program, highlighting the technical competence of the Brazilian industry in submarine construction and the progress in the country’s naval defense capabilities.
