AUKUS | U.S. Secretary of War Pete Hegseth, Australian Deputy Prime Minister and Defence Minister Richard Marles and UK Secretary of State for Defence Wes Streeting have announced USS Colorado will be the first U.S. Navy Virginia-class fast-attack submarine assigned to SRF-West, which will begin in Western Australia in late 2027.

This announcement comes ahead of the United States Submarine Maintenance Period, which begins later this week and will further demonstrate Australia’s growing ability to sustain U.S. and UK nuclear-powered fast-attack submarines. These activities represent an important step forward for AUKUS, strengthening allied cooperation and our collective ability to deter threats and promote security and stability in the Indo-Pacific.
