Naval Group Launches Third Brazilian Scorpene Submarine

The third Scorpène submarine of the ProSub program was launched at the Itaguaí Naval Base on March 27.

Present at the event were Brazilian President Luiz Inácio Lula da Silva and French President Emmanuel Macron. The Tonelero was constructed entirely in Brazil by Itaguaí Construções Navais (ICN), following successful technology transfer and partnership with Naval Group. Following closely after the delivery of the Humaita, the Tonelero will undergo sea trials and is expected to be delivered in 2025. The final submarine of the series, Angostura, is scheduled for launch in 2025.

In 2009, the Brazilian Navy selected Naval Group for its ProSub program, aimed at bolstering its submarine force with four new conventional submarines (SSK) and the development of an indigenous nuclear-powered submarine (SSN). The Scorpène submarines are manufactured and assembled at the Itaguaí shipyard by ICN, with technology transfer, equipment supply, and technical assistance provided by Naval Group. Brazilian teams at the ICN shipyard underwent training in submarine construction techniques in France, as part of a comprehensive program for local workers. Local suppliers, selected and qualified by Naval Group, have joined the supply chain for the ProSub contract.

The stealthy Scorpène submarines are designed for both ocean-going and shallow-water operations. They fulfill a range of missions including Anti-Surface and Anti-Submarine Warfare, special operations, and intelligence gathering. Equipped with six weapon launching tubes and capable of carrying up to 18 weapons (torpedoes, missiles), Scorpène submarines are armed with the latest generation combat system, SUBTICS, which can be integrated into new platforms or existing submarines undergoing modernization.

The Brazilian Scorpene variant is slightly longer to accommodate a larger crew, more provisions, and fuel for extended patrols. All Brazilian Scorpène submarines will be equipped with Naval Group’s F21 heavyweight torpedo.
