Riachuelo was ordered in 1972, separately from her two sister boats. The submarine, built by Vickers Shipbuilding and Engineering at their shipyard in Barrow, was laid down on 26 May 1973, and launched on 6 September 1975. She was commissioned into the Brazilian Navy in early 1977.
Riachuelo was decommissioned in 1997.. She is now displayed at the Navy Cultural Centre in Rio de Janeiro.
