Submarine “Riachuelo” reinforces Brazil’s sovereignty in the Blue Amazon

ElSnorkel – The “Riachuelo” is the first of a class of four conventional submarines with diesel-electric propulsion, which will allow greater deterrent power in the 5.7 million km2 of the Blue Amazon, whose rich waters, seabed and subsoil are important for economic, scientific and environmental development. It is in this maritime area where Brazilians carry out fishing activities, where 95% of Brazilian foreign trade passes and where biological and mineral resources are exploited.
