Australia, the United Kingdom, and the United States are set to announce a new defence pact today, including the sharing of highly advanced nuclear-powered submarine technologies. 

The tri-national pact will attempt to advance Australia’s current naval fleet in an effort to enforce security in the Indo-Pacific region.

While long-range strike capabilities are also being discussed, the nuclear technologies are exclusively for the submarine’s propulsion systems, and the pact will not include sharing of nuclear weapons.
