<p>Brazilian shipbuilder Itaguaí Construções Navais (ICN) launched the third unit of the Riachuelo-class diesel-electric attack submarine (SSK), S<em> Tonelero</em> (S42), on 27 March.</p>
<p>The launch of the S<em> Tonelero</em> (S42) SSK by ICN (a joint venture between Novonor and Naval Group) took place at the Itaguaí Naval Complex.</p>
<p>The submarine is scheduled to be commissioned for Brazilian Submarine Force Command in May 2025, after the vessel completes successful sea trials, the Brazilian Navy told <em>Janes</em>.</p>
<p>S <em>Tonelero</em> is the third of four Riachuelo-class S-BR submarines purchased in 2009 as part of the Submarines Development Program (PROSUB), within the framework of the French-Brazilian strategic defence co-operation agreement signed in 2008.</p>
<p>The S-BR multi-purpose submarine was designed to fulfill anti-surface and anti-submarine warfare, special operations, and intelligence gathering missions.</p>
<p>It has six weapon launching tubes for the MBDA Exocet SM39 Block 2 Mod 2 anti-ship missile and Naval Group F21 heavyweight torpedo.</p>
<p>The first-of-class boat S <em>Riachuelo</em> (S40) and the second submarine S <em>Humaitá</em> (S41) were commissioned in September 2022 and January 2024 respectively. ICN is in the final stages of building the last Riachuelo-class submarine S <em>Angostura</em> (S43). The submarine is scheduled to be launched in 2025 and commissioned in 2026, the Brazilian Navy told <em>Janes</em>.</p>
