Brazil launches first Scorpene class submarine

The Brazilian Navy has launched its first Scorpène class submarine, the Riachuelo (S 40) at a ceremony took place at the Itaguaí Navy base.

In 2009, Naval Group was entrusted by the Brazilian Navy with designing and transferring the technology for four conventional Scorpène submarines, and for the design and manufacturing assistance for the non-nuclear part of Brazil’s first nuclear-powered submarine. The contract also included the support for the construction of a naval base and a shipyard in Brazil.

The Prosub program is a key extension of the strategic defence cooperation agreement signed in December 2008 in Rio de Janeiro.

The launching of the Scorpène Riachuelo in presence of the Brazilian head of state today demonstrates the success of this program, with both the successful completion of the first submarine and of the shipyard’s infrastructure. The latter is being built by a Brazilian company, Construtora Norberto Odebrecht (CNO), based on Naval Group specifications and on the French group’s experience in the design, production engineering and in-service support of submarines.

The Riachuelo will start sea trials in 2019 for delivery in 2020.

Scorpène is the conventional submarine designed by Naval Group for the export market. It demonstrates both Naval Group’s ability to deliver best in class submarines and to conduct successful transfers of technology. Today 14 Scorpène submarines are in operational service or being built, for the Chilean Navy (2 units), the Malaysian Navy (2 units), the Indian Navy (6 units) and the Brazilian Navy (4 units).

The Scorpène design is adapted to fit each navy’s specific requirements. Thus, the Brazilian Scorpène will be slightly longer to carry a larger crew, almost double the patrol range, and be able to cover greater distances.

Scorpène is ideally suited for action and operational effectiveness. Robust and enduring, it’s an ocean-going submarine also designed for shallow waters operations. Multipurpose, it fulfils the entire scope of missions such as anti-surface and anti-submarine warfare, special operations, offensive minelaying and intelligence gathering. Integrating improvements from French Barracuda-Class fast-attack submarine, Scorpène has cutting-edge capabilities.
