The SSN-AUKUS, also known as the SSN-A, is a planned class of nuclear-powered fleet submarine (SSN) intended to enter service with the United Kingdom's Royal Navy in the late 2030s and Royal Australian Navy in the 2040s. The class will replace the UK's Astute class and Australia's Collins class submarines.

The Collins-class submarines are Australian-built diesel-electric submarines operated by the Royal Australian Navy (RAN). The Collins class takes its name from Australian Vice Admiral John Augustine Collins; each of the six submarines is named after significant RAN personnel who distinguished themselves in action during World War II. The six vessels were the first submarines built in Australia, prompting widespread improvements in Australian industry and delivering a sovereign sustainment/maintenance capability.
