The US Navy has reactivated Submarine Squadron 3 (CSS-3) to support the Submarine Rotational Force-West (SRF-West) at HMAS Stirling, Western Australia, according to a report published by DVIDS on 10 June 2026.
Rear Admiral Chris Cavanaugh, commander, Submarine Force, US Pacific Fleet, authorised the return of the squadron, which was previously based at Pearl Harbor, Hawaii, until its decommissioning in February 2012.
The decision follows the trilateral Joint Statement issued by Australia, the UK and the US on 30 May.
That statement confirmed progress towards meeting key milestones for SRF-West under the Australia–UK–US (AUKUS) security partnership.
