Australian Prime Minister Scott Morrison, UK Prime Minister Boris Johnson and US President Joe Biden held a virtual news conference on Wednesday to unveil their new joint partnership on advanced defense-tech sharing.

Morrison revealed in his address that the first major initiative of the new trilateral security partnership - dubbed AUKUS - will be to deliver Australia its first nuclear-powered submarine fleet.

The Australian Prime Minister detailed that the trio will take the next 18 months to decide the "best way to achieve this."

"We intend to build these submarines in Adelaide, Australia, in close cooperation with the United Kingdom and the United States," Morrison added.
