The Navy of Brazil passed a major milestone in the PROSUB Submarine Development Program when, on September 2, the Nuclebrás Heavy Equipment SA (NUCLEP) delivered to Itaguaí Construção Naval (ICN), the final section of the pressure hull of the first conventional submarine (S-BR1), the "Riachuelo."


The ceremony marking the delivery, presided by the Commander of the Navy, Admiral- Eduardo Bacellar Leal Ferreira, marked the completion of the first phase of construction of the submarine "Riachuelo".


This delivery will now allow all sections of the pressure hull to move to the next phase of equipment and systems installation. The pressure hull is composed of cylindrical sections structurally reinforced to withstand the maximum operating pressure of the submarine.


PROSUB is a partnership between Brazil and France and provides, among other things, the transfer of technology necessary to the construction of four conventional diesel-electric submarines and one submarine with nuclear propulsion.
