Five years after AUKUS was signed, the first submarine has been named

Key points

• The United States has revealed the USS Colorado as the first nuclear submarine to deploy to Australia under the AUKUS pact. The submarine will be based at HMAS Stirling in Western Australia from late 2027, Defence Minister Richard Marles said in a joint statement.
• It is the first of up to four US submarines, plus one from Britain, expected to rotate through the base.
• The plan has drawn criticism after the US said it would supply second-hand vessels rather than the new submarines first promised.
