France, the construction of the submarine was entirely carried out in Brazil by
Itaguaí Construções Navais (ICN). It is renamed as Riachuelo class. It is the

The submarine is equipped with six launcher tubes with 18
torpedoes and missiles.
Riachuelo has a length of 72 m and a surface displacement
weight of 1,600 – 2,000 tons. This submarine can travel at a dive speed of
above 30 knots and can dive to a maximum depth of 300 m.
