What is AUKUS?

Oct. 3, 2023

As part of the AUKUS initiative with Australia and the US, the UK has given three UK businesses a 4 billion pound ($4.9 billion) contract to design and build an attack submarine powered by nuclear energy.

About AUKUS:

  • Established in 2021, the AUKUS is intended to be a strategic partnership among Australia, the United Kingdom (UK), and the United States to bolster their allied deterrence and defense capabilities in the Indo-Pacific.
  • The trilateral partnership, which builds on their decades-long security cooperation, has two pillars.
    • Pillar I revolves around the acquisition and development of conventionally armed nuclear-powered submarines for the Royal Australian Navy;
    • Pillar II calls for collaboration on advanced capabilities that will involve technology and information sharing;
  • What is the submarine component?
    • It is designed to equip Australia with nuclear-powered attack submarines (SSNs).
    • In total, Australia will end up with eight of the new nuclear submarines, called SSN-AUKUS.
    • Those submarines will be based on a British design but have American technology or an American combat system.
    • The deal marks the first time the US has shared nuclear propulsion technology with an ally other than the UK.
    • It will significantly enhance Australia’s undersea capabilities in the Indo-Pacific.
    • These countries, however, made it clear that their aim is not to arm the new submarines with nuclear weapons. This is because Australia is a signatory to the Nuclear Non-proliferation Treaty (NPT), which bans it from acquiring or deploying nuclear weapons.
