The hull of Riachuelo was laid down at Cherbourg, France on 27 May 2010 and it was jumboized at the Brazilian Navy Shipyard in Itaguaí in late 2012.[2]
The first submarine Riachuelo was launched on 14 December 2018,[14] the Humaitá was launched on 11 December 2020, and the Tonelero on 27 March 2024.[15]
