Construction Work on First S-BR Scorpene Class Submarine Starts in Brazil


The ceremony held in presence of the Brazil President, Dilma Rousseff, the Brazilian Ministry of Defence, Nelson Jobim, the French Ministry of Defence, Gerard Longuet and the Chairman and CEO of DCNS President Patrick Boissier and for Odebrecht, the CEO, Marcelo Odebrecht.

The start of construction work in Brazil on the first S-BR Scorpene class submarine is one of the most important milestones of the programme. It demonstrates that the engineers, technicians and workers trained at DCNS in France have acquired all the necessary knowledge and skills, particularly the steel forming and welding techniques used in the construction of the pressure hull. It points out also that Brazil has the state-of-the-art industrial facilities needed to produce latest-generation submarine hulls. All aspects of the programme are supervised by the Brazilian Navy, under a wide-ranging technology transfer agreement.

The programme covers the design and construction of four Scorpene conventional-propulsion submarine submarines, design and construction assistance with the non-nuclear portion of Brazil’s first nuclear-powered submarine and support for the construction of a naval base and a naval shipyard. The first of the four Scorpene-class conventional-propulsion submarines is scheduled to enter active service in 2017. These four submarines feature conventional diesel-electric propulsion. Their length overall is approximately 75 metres, with a surface displacement of close to 2,000 tonnes. They will be operated by a crew of 30 to 45.

The four Scorpene conventional-propulsion submarines meet the particular specifications of the Brazilian Navy and are perfectly tailored to the protection and defence of Brazil’s 8,500-kilometre coastline. They are highly versatile ocean patrol submarines, designed for all types of missions, including anti-surface warfare, anti-submarine warfare, special operations and intelligence gathering.

This latest milestone further underscores DCNS’s commitment to Brazil, the Brazilian Navy and local industry, which will play an active role in the construction of the country’s first nuclear-powered submarine.
