Australia is going to spend at least $268bn-$368bn to acquire nuclear-powered submarines.
The Aukus deal is a trilateral security partnership between Australia, the United States, and the United Kingdom.
The deal was announced on September 15, 2021 in a virtual press conference, and focuses on enhancing regional security in the Indo-Pacific region.
One of the key components of the deal is Australia's acquisition of nuclear-powered submarines from the US and the UK.
The submarines will be equipped with advanced technology and are intended to help Australia counter China's growing military presence in the region.
The Aukus deal has been criticised by China, which sees it as an attempt to contain its rise as a global power.
The Aukus deal has raised concerns over nuclear proliferation, as it involves the transfer of nuclear technology to a non-nuclear weapons state(Australia).
The deal has also been hailed as a significant milestone in the trilateral relationship between the US, the UK, and Australia.
India has welcomed the deal as a part to deter China.
