AUKUS: USS Colorado Announced as First Submarine for SRF – West
The designation of USS Colorado as the first Virginia-class boat assigned to Submarine Rotational Force-West puts a specific hull and date against AUKUS Pillar One, with rotations from HMAS Stirling due to begin in late 2027. It converts a framework commitment into a scheduled US submarine presence in Western Australia, driving infrastructure, maintenance and workforce milestones at Henderson and Garden Island that Australia must meet. It also signals continued US follow-through on AUKUS at a time when the pace of Virginia-class production and the eventual sale of boats to Australia remain the central uncertainties.
