The US, UK and Australia have unveiled a decades-long project to supply Canberra with nuclear-powered submarines, entering a historic partnership that binds the allies more tightly as they counter China in the Indo-Pacific. Under the three-stage plan, Australia and Britain will co-build a new submarine. The UK and Australia each plan to build at least eight of the multibillion-dollar submarines. The first Australian boats will not enter service until the early 2040s, with the full fleets being built over the following two decades. Australia will also invest in the US and UK’s defense industrial base, an unprecedented move aimed at boosting manufacturing capacity at strained shipyards.
