Riachuelo performs independent navigation
The PROSUB diesel-electric attack submarine programme for the Brazilian Navy took a step forward on 12 August, when the first-in-class boat Riachuelo performed its first independent navigation test without the need for tugs.
Rudders and various onboard systems (navigation and propulsion, diesel generators, battery chargers and communications systems) were tested and general training was conducted with the crew.
Shephard Defence Insight notes that PROSUB boat two, Humaitá, is expected to be launched in September 2020, with boat three (Tonelero) due in December 2021 and boat four (Angostura) in December 2022.
The submarines are expected to be commissioned a year after launch, with all four in service by the end of 2023.
