SSN-AUKUS

The SSN-AUKUS is a planned class of nuclear-powered fleet submarines intended to enter service with the UK's Royal Navy in the late 2030s and the Royal Australian Navy in the early 2040s. The class will replace the UK's Astute-class and Australia's Collins-class submarines and will be powered by Rolls-Royce's pressurized water reactors. The UK commenced the Astute class replacement project in 2018 and later renamed the ongoing design SSN-AUKUS in March 2023, under the 2021 AUKUS trilateral security partnership.learn more on wikipedia
