First Dive for Leading Submarine of Brazilian Prosub program
Brazilian Navy's Riachuelo Submarine of the Prosub program

The first Brazilian submarine in the Prosub program, ‘Riachuelo,’ successfully completed her first independent dive down to safety depth off Sepetiba Bay near Rio during the night of November 28.

For nearly 12 years, the Prosub program has involved more than 3,000 French and Brazilian employees, whether in the design and construction of conventional submarines (SBR), or in assistance with the design of the future nuclear-powered submarine (SNBR) or in the design of Itaguaï naval base, a Naval Group release said.

It also involves - along with other French and local suppliers as well as our partners - our crew training subcontractor Navfco.

“This technical success represents, above all, an accomplishment and a magnificent reward for an exceptional human adventure!” commented Sébastien Roulland, the programme's Whole Warship Architect, as he disembarked after this key first for the programme.

The Riachuelo will be followed up with the upcoming launch of the Humaitá, second in the series, in mid-December; then the final joining of the Tonelero, the third conventional submarine in the Prosub programme.
