(AP) — Defense Secretary Pete Hegseth has kicked off a series of meetings with British and Australian counterparts in Washington that are aimed at moving forward with the large nuclear submarine building and technology sharing pact between the three nations known as known as AUKUS.

Ahead of the meetings, the British defense minister said he’s “all in” following a U.S. review of the deal.

“Those reviews are now done,” U.K. Defense Secretary John Healey told reporters Wednesday. He added that “all three of us are now determined to reboot AUKUS with a new commitment and a new determination in particular to deliver.”

The deal was originally inked in 2021. The Pentagon recently determined that the agreement was in the U.S. national security interest.

It includes the sale of three U.S.-built nuclear-powered submarines to Australia starting in 2032.
