The four sections of the Humaitá submarine's hull are already at the ICN, coming from UFEM, which is also located in Itaguaí. Now begins the welding phase to close the hull
The construction works of the second conventional submarine of the PROSUB Program, the “Humaitá”, are in full swing. Today (19/06) ICN, Itaguaí Construções Navais, from Itaguaí (RJ), completed the transfer of sections 3 and 4.
The sections were built at the UFEM factory, also in Itaguaí, and were the last to be received at the ICN. Now the shipyard will begin the final joining phase of the sections in order to close the vessel's hull.
As already published by Click Petróleo e Gás, the section 1 and section 2 have already been transferred to the ICN shipyard on April 25th and May 29th respectively.
These last two transferred sections make up the bow part of the submarine, where important compartments for the operation of the submarine are located, such as the control room, masts, periscope and torpedo launch tubes.
The total weight of the four sections transferred to ICN add up to 440 tons and the second conventional submarine (S-41) of the PROSUB program will be 72 meters long.
The vessel will have a displacement of around 2 tons and its delivery is scheduled for the second half of 2020.
The PROSUB Program of the Brazilian Navy foresees the construction of four submarines with conventional propulsion (Diesel-electric) and one with nuclear propulsion, the first to be manufactured of this type in Brazil.
Humaitá is the second of the four and should be ready by the end of 2022.
The first submarine in the program was launched at sea on December 14 of last year and was named Riachuelo (S40) and its sea test is scheduled for this year.
The Humaitá sea test (S-41) is scheduled for 2020, the Tonelero (S42) in 2021 and the Angostura (S43) in 2022.
