Brazil Navy Riachuelo class submarine conducts immersion tests

The Submarine “Humaitá” (S 41) carried out, throughout the month of March, dynamic immersion tests and immersion in great depth, on the coast of Rio de Janeiro. The submarine is the second of the four with diesel-electric propulsion foreseen by the Submarine Development Program (PROSUB) and continues the schedule of acceptance tests at sea, before its definitive incorporation into the Brazilian Navy. After the “Riachuelo” submarine, the “Humaitá” will be one more to reinforce the protection of Brazilian jurisdictional waters in the South Atlantic.

The Dynamic and Great Depth Immersions are fundamental steps in the submarine's construction and crew training process, as it not only assesses its ability to dive safely, but also attests to the level of readiness of the submarine's crew. The result of these assessments consolidates one more step foreseen in the schedule until its definitive delivery.

Frigate Captain Martim Bezerra de Morais Júnior, future Commander of the “Humaitá”, states that “The crew is engaged and committed, applying all the knowledge received and efforts to drive the submarine safely at sea during the testing period, so as to to ensure that it is incorporated into the Navy's Operating Sector, thus fulfilling its purpose of contributing to the improvement of the defense of the Blue Amazon and, consequently, reinforcing Brazil's sovereignty”.

The PROSUB schedule points to the possibility of transferring the S 41 to the Operating Sector, in the second half of this year.

Tests in the operational environment of “Humaitá” represent another important step within the scope of PROSUB, which consolidates itself as a Strategic Program for the Brazilian State, training specialized labor and raising the country's strategic potential for scientific and technological development.
