The AUKUS nations, comprising Australia, the UK, and the US, are marking a significant milestone as a US nuclear-powered submarine, the USS Hawaii, undergoes maintenance at HMAS Stirling in Western Australia for the first time. This Submarine Tendered Maintenance Period (STMP) demonstrates a collaborative effort to enhance security in the Indo-Pacific region, with Australian personnel having undergone extensive training to participate in the maintenance alongside their US and UK counterparts. The defense ministers emphasized their commitment to nuclear non-proliferation standards and the safe operation of nuclear-powered vessels, drawing on decades of experience from the US and UK navies. The STMP is expected to bolster Australia's capabilities as it prepares to operate its own conventionally-armed nuclear submarines in the future. The initiative also includes the rotational presence of British and US submarines at the Australian base, starting in 2027. Importantly, the Australian defense department assures that no radiological material will be transferred ashore during this maintenance process.
