The AUKUS pact between Australia, the United Kingdom and the United States has swiftly shifted the international dialogue on naval power (Hellyer & Stevens, 2022). For the first time, a non-nuclear weapon state is being armed with nuclear-powered submarines, thus changing not only the Indo-Pacific security environment but, additionally, opening a new chapter in strategic defence cooperation (Cheng, 2022). Whilst London and Washington were putting importance on the strategic need of countering China, Europe wаs left watching from afar: particularly France, whose billion-euro submarine deal with Australia had quickly collаpsed overnight (Tertrais, 2021). This аrticle explores how AUKUS redefines traditional defence norms and remodels the global nuclear submarine balance (Hellyer & Stevens, 2022). Likewise, it examines the implications for the European Union, which has long aimed for larger strategic autonomy, yet still struggles to coordinate effectively at sea (Fiott et al., 2021). Geographically speaking, AUKUS may be a distant pact, however, its message to Europe is as clear as day: naval power matters, and partnerships formed on trust, swiftness, as well as strategic clarity, are already setting the pace (Fiott, 2018).
