Landmark Military Sale Expands Security Ties Beyond US Alliance

Australia and Japan have signed contracts for a landmark $7 billion warships deal, marking Tokyo’s most consequential military sale since ending its military trade ban in 2014. The deal involves the supply of three upgraded Mogami class multi-role frigates to be built in Japan, with Australia building eight more.

This development was first reported by Reuters.
