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.[3]

The first submarine Riachuelo was launched on 14 December 2018, and began sea trials in September 2019,[10] the Humaitá was launched on 11 December 2020.
