AUKUS (/ˈɔːkəs/AW-kəs), also styled as Aukus, is a trilateral security partnership between Australia, the United Kingdom, and the United States intended to "promote a free and open Indo-Pacific that is secure and stable."[1] Initially announced on 15 September 2021, the partnership involves two lines of effort referred to as pillars.[2][3] Pillar 1 focuses on Australia acquiring nuclear-poweredattack submarines and the rotational basing of US and UK nuclear-powered attack submarines in Australia.[4] Pillar 2 entails the collaborative development of advanced capabilities in six technological areas: undersea capabilities, quantum technologies, artificial intelligence and autonomy, advanced cyber, hypersonic and counter-hypersonic capabilities, and electronic warfare; and in two broader functional areas: innovation and information sharing.[5][3]
AUKUS is widely seen as a response to the perception among its members that the People's Republic of China poses a threat to the Indo-Pacific region.[6][7] The Chinese government said, when the partnership was announced, that it risked "severely damaging regional peace" and had a "cold-war mentality".[8]
The creation of the partnership spelled the end of a French–Australian submarine deal worth €56 billion (A$90 billion) that was controversially cancelled by Australia.[9][10] The Australian government only gave the French government a few hours notice of the cancellation of the deal before the public announcement of AUKUS.[11][12] The Australian government agreed to a €555 million (US$584 million) compensation settlement with French defence contractor Naval Group.[13][14]
