The AUKUS Pact: More of a Costly Signal than Effective Deterrence
Number 2 | 2025 | ISSN: 1862-359X
In 2021, Canberra, London, and Washington announced the AUKUS security pact on nuclear-powered submarines for Australia and cooperation on new technologies with military applications. It remains intact under the second Trump administration: in early 2025, Canberra made a first payment to help uplift the US submarine industrial basis. The pact’s implementation as a whole is, however, questionable.
In the short to medium term, AUKUS the pact exerts no deterrent effect vis-à-vis the People’s Republic of China or other states. Even if things work out optimally, the first submarines will be delivered to Australia only in the 2030s.
How many, if any at all, nuclear-powered submarines the US and the UK will be able to deliver to Australia is unclear. The political risks and industrial challenges involved in their trilateral security cooperation are high, also given that naval shipyards for submarines in the US and the UK are having difficulties meeting domestic demand.
Building, maintaining and overhauling, as well as manning the future nuclear-powered submarines also constitute huge challenges for Australia in terms of personnel, training, and research.
Policy Implications
The AUKUS pact is primarily a costly foreign policy signal. The three partners are seeking to demonstrate their resolve to meaningfully respond to the military threat posed by the PRC. Canberra is binding itself even closer to the US in security terms. This portends substantial challenges and political risks for Australia, one of Germany’s few genuine values-based partners in the Indo-Pacific.

This article examines Australia’s ‘Pacific Step-up’, a signature foreign policy initiative of the Scott Morrison government (2018‒2022), from a signalling perspective. It also explains why Solomon Islands signed a security agreement with China in 2022 despite Australia’s wooing of Pacific Island countries.
Australia and New Zealand have in recent years been at the forefront of the growing confrontation between the ‘West’ and China. In this article, Patrick Köllner takes stock of and compares the Australian and New Zealand recalibrations of their China policies, highlighting similarities as well as differences.
China’s Global Security Initiative projects its stability-focused security model abroad. How do East Africa, Southeast Asia, and the Middle East perceive the GSI? What does this mean for the future of the international security order? And how should Germany and the EU best respond?
The geopolitical competition between the USA and China takes place primarily in the Indo-Pacific. Co-edited by GIGA researcher Johannes Plagemann, this Special Issues explores regionals states' as well as the EU's ambivalent reactions to it through the prism of 'foreign policy signaling'.
Using a Comparative Area Studies approach to Africa, Latin America, the Middle East, and South Asia, we discuss how regional issues shape global non-proliferation and disarmament politics. Focus is on the nuclear-weapon-ban norm, recently codified in the Treaty on the Prohibition of Nuclear Weapons.
