Brazil advances submarine construction

19 January 2018

Brazil is preparing to integrate, finish, and test the first three unified hull sections for Riachuelo (S-40), Brazil’s first of four planned diesel-electric attack submarines, at the Itaguaí shipyard.

The hull sections were moved on 13 and 14 January from the Unidade de Fabricação de Estruturas Metálicas (UFEM) metallic structures plant, where they were pre-outfitted, to the Estaleiro de Construção (ESC) assembly hall, by shipbuilder Itaguaí Construções Navais (ICN).

The remaining two sections will be transferred later.

The submarine, also known as S-BR 1, is scheduled to be launched in the second half of 2018 and delivered in 2020. Riachuelo was originally scheduled to be launched in January 2016 and commissioned in 2017, but the programme has been slowed by budget-funding delays.
