Under the terms of the agreement, Mitsubishi Heavy Industries will construct the first three frigates in Japan, with the remaining eight to be built in Western Australia. The initial vessel is slated for delivery in 2029, marking the fastest surface combatant acquisition in the history of the Royal Australian Navy.

The Mogami-class frigates are designed to replace Australia's aging ANZAC-class ships. These advanced vessels will feature state-of-the-art missile systems, helicopter operations capabilities, and a reduced crew requirement of 92 personnel, enhancing operational efficiency.

This deal not only elevates Japan's defense export profile but also strengthens its strategic partnership with Australia, extending beyond traditional alliances. The collaboration was highlighted during a signing ceremony aboard the JS Kumano, a Mogami-class vessel participating in Exercise Kakadu naval drills, attended by Japanese Defense Minister Shinjiro Koizumi and Australian Defense Minister Richard Marles.

Aligning with Australia's new defense strategy, which includes a $38 billion increase in defense spending over the next decade, this partnership reflects a commitment to expanding regional defense ties and developing domestic defense industry capabilities.
