The First Of The Four Submarines Of The Prosub Program Will Start, Now This Month Of August, In Itaguaí, The Sea Operation Tests

The ICN shipyard (Itaguaí Construções Navais), a joint venture between Naval Group and Odebrecht Engenharia e Construção, informed the Brazilian Navy that the sea trial of the first of the four S-BR diesel-electric attack submarines (modified Scorpène class) from the Submarine Development Program (Prosub) will start this August.
The sea trial of the vessel and its equipment is expected to last until the first half of 2020, while the commissioning of the submarine is scheduled for October 2020.

The Tests

The Brazilian Navy reported that not only the submarine’s equipment will be tested; the Sea Trial will also serve to test the launch of a heavy F21 torpedo of 533 mm from Naval Group and a mock-up of a MBDA Exocet SM39 Block 2 Mod 2 anti-ship missile.

It is important to remember that the submarine (S-40) named “Riachuelo” was launched from the Naval Shipyard of Itaguaí on December 14, 2018 and is equipped with armaments capable of patrolling areas where the Pre-Salt will be explored.

As reported by Click Petróleo e Gás, the construction works of the submarines in Itaguaí are well advanced, and the four hull sections of the second submarine, the “Humaitá” are already at the ICN, coming from UFEM, which is also located in Itaguaí.

The Prosub program provides for the construction of four submarines; after the Riachuelo comes the Humaitá (S41), with a launch scheduled for 2020, the Tonelero (S42) in 2021, and the Angostura (S43) in 2022.

A fifth unit is planned, but its propulsion will be nuclear, and the project, which will also be executed at the Itaguaí Shipyard, is progressing smoothly.

ICN and NUCLEP are making strides towards another industrial leap by joining forces for the manufacturing of the first qualification section of the SN-BR Álvaro Alberto, the first nuclear-powered submarine in Latin America.
