Brazilian Navy’s new submarine, Riachuelo (S-40), is in the final preparations for the sea trials with a month latency, according to Brazilian domestic press.
Riachuelo will carry out initial tests of several systems (propulsion, navigation, communication systems etc.) at port until its first departure to sea. At a later stage of sea testing, the launch of the F21 heavy torpedo manufactured by the Naval Group and a mock-up of the Exocet SM39 Block 2 Mod 2 anti-ship missile manufactured by the MBDA is also planned.
The Riachuelo Submarine, first of four Scorpène-class conventional attack submarines ordered by the Brazilian Navy under the Prosub Submarine Development Program of the French Naval Group, was launched on December 14, 2018, with a ceremony held at the Itaguaí Naval Complex.
According to the Navy schedule, next submarine, the Humaitá (S 41), is expected to be launched in 2020, and she will be followed by the Tonelero (S 42) in 2021 and Angostura (S 43) in 2022.
