The first-of-class Riachuelo-class (Modified Scorpene-class) S-BR diesel-electric submarine Riachuelo (S40) is scheduled to be launched on 14 December at the Itaguaí Naval Complex in Itaguaí, where the ship was built by Itaguaí Construções Navais (ICN).
The boat is currently at the Estaleiro de Construção (ESC) assembly hall and will be moved to TTS Syncrolift's ship lift to be lowered into the water on the launch date.
The ship will then spend another estimated two years undergoing pier tests and sea trials. It is scheduled for delivery to the Brazilian Navy in 2020.
The S-BR is built in five sections. Riachuelo bow's third and fourth sections were constructed in Cherbourg, France. The remaining three boats - Humaitá (S41), Tonelero (S42), and Angostura (S43) - are being fully constructed in Brazil.
Humaitá , Tonelero , and Angostura are in different stages of construction. Pre-outfits of hull sections and equipment installation on Humaitá and Tonelero are taking place at the UFEM metallic structures manufacturing unit, while state-owned company Nuclebrás Equipamentos Pesados (NUCLEP) will fabricate sections for Angostura .
