USS Colorado Named Lead AUKUS Attack Boat for 2027 Australia Rotation

The Pentagon and Australia announced USS Colorado (SSN-788) will be the first Virginia-class submarine assigned to Submarine Rotational Force-West at HMAS Stirling, Western Australia, starting 2027. This is a concrete milestone for AUKUS Pillar I, formalizing the planned rotational presence of US nuclear-powered attack submarines in the Indo-Pacific. The selection signals continued implementation of the trilateral security pact, though the operational timeline and force levels remain subject to infrastructure and regulatory milestones.
