This comes after US President Joe Biden, UK Prime Minister Rishi Sunak, and Australian PM Anthony Albanese revealed, at an AUKUS summit in San Diego, the map-out of their plan to establish a new fleet of nuclear-powered attack submarines within the AUKUS framework.

The plan entails the US' provision of three American Virginia-class nuclear-powered submarines to Australia in the 2030s. Biden clarified after the announcement that he is not concerned about China's opinion.

Australia will buy as many as five US nuclear-powered submarines and later build a new model with US and British technology under a plan to strengthen the AUKUS Western alliance across the Asia-Pacific against rising China, a US official said on Monday.

The Australian Department of Defense explained that “Australians have already commenced training and working on UK and US nuclear-powered submarines and in UK and US facilities,” adding that it would lead to the creation of 20,000 jobs over the coming 30 years.
