How the US Plans to Expand its Submarine Industrial Base for AUKUS

WASHINGTON — Defense officials are optimistic that billions of dollars of investments in the U.S. submarine industrial base will increase capacity to and even above the required two-a-year attack sub construction rate, allowing the U.S. to build for Australia under a new international agreement without restricting the American fleet.

On Monday, the U.S., Australia and the United Kingdom unveiled new details about their partnership to produce for Australia its own nuclear-powered submarine by 2040, known as the SSN AUKUS. The U.S. is offering an interim capability of three to five Virginia-class submarines, either newly built or used, in the 2030s.
