The three sections of the Brazilian Navy's first Scorpene submarine Riachuelo have been integrated into a single unit at Itaguaí.
The pre-built-and-equipped sections of the first Scorpene were created at the Brazilian shipyard Itaguaí Construções Navais (ICN) and moved from the pre-outfitting to the assembly site in January.
The sections will be welded to make up the 71-metre diesel-electric submarine. Riachuelo is scheduled to be commissioned in 2020.
France's Naval Group provided the submarine blueprint, inner equipment and technical assistance.
S40 is the first of four submarines to be built for Brazil under an agreement between French Naval Group (formerly DCNS) and Brazil in 2008.
