Brazilian Navy receives second submarine submarine built by Prosub

Ceremony on Friday (12) also marks the delivery of the building for the Submarine Force Command, which will house the support structure for the operation of the vessels

Itaguaí Construções Navais (ICN), a partnership between Novonor and the French Naval Group, delivered the Humaitá submarine this Friday (January 12), the second conventional submersible built for the Brazilian Navy’s Submarine Development Program (Prosub). In addition to the vessel, the ceremony also marked the handover of the civil installations that will house the support structure for the operation of the submarines built by the program, work carried out by the OEC construction company.

Humaitá, the second of the four diesel-electric submarines planned under Prosub, of the “Riachuelo” class, is now ready to begin its cycle of operations and missions, including patrolling the Brazilian waters that make up the Blue Amazon and areas of strategic importance to Brazil in the South Atlantic. The execution of the activities related to the submarines “Tonelero”, “Angostura” and the Conventionally Nuclear-Powered Submarine “Álvaro Alberto” are still going ahead as planned and are progressing at different stages.

“This important delivery makes the entire OEC team proud of its technical aspects and the performance of the construction, as part of the most important ongoing project for Brazil’s sovereignty,” said Mauricio Cruz Lopes, CEO of OEC construction company.

OEC is responsible for building all of Prosub’s infrastructure, such as the building that will house the Submarine Force Command, which was also handed over to the Brazilian Navy on this date, responsible for the operational control of submersibles at sea and diving activities in the Brazilian Navy. The structure has a four-storey building in a built-up area of almost 5,000 square meters and is expected to house a total of more than 200 people. The structure includes an auditorium, rooms reserved for the Naval Command, accommodation and control facilities. Around the building, preference was given to planting native species from the restinga, such as pitangueiras, jerivás and pau-brasil.
