The Pentagon has named USS Colorado as the first US nuclear-powered attack submarine to be based with Australian forces, giving concrete form to Submarine Rotational Force-West at HMAS Stirling.

It also deepens Australia's operational and political entanglement with US force posture in the Indian Ocean and beyond.
