Australia to host USS Colorado as first US nuclear submarine under Aukus pact
The move begins a rotational force of up to four U.S. submarines and one British submarine to help Australia build nuclear-submarine skills.
- On Monday, the Pentagon announced that USS Colorado will be the first U.S. Navy Virginia-class fast-attack submarine assigned to Submarine Rotational Force-West, beginning rotation at Western Australia's HMAS Stirling in late 2027.
- This assignment supports the $386 billion AUKUS pact by expanding regional maintenance infrastructure and accelerates Australia's readiness to own and operate nuclear-powered submarine capability.
- As a Block III Virginia-class submarine, Colorado reaches speeds exceeding 46km/h, significantly outpacing the 37km underwater top speed of Australian Collins-class submarines.
- Tasmanian independent senator Jacqui Lambie described second-hand vessels as "trash," though ministers and military brass insist used submarines remain the best operational option.
- Defense Secretary Pete Hegseth, Defence Minister Richard Marles, and UK Secretary of State Wes Streeting confirmed the program remains "full-steam ahead" as nations prepare for a United States Submarine Maintenance Period starting later this week.
