Mogami-class multi-role frigates

Australia and Japan have signed a landmark $7 billion defence agreement for the supply of advanced warships, marking a significant step in deepening their strategic partnership.

Australian Defence Minister Richard Marles stated that the agreement underscores both nations’ commitment to successfully delivering the vessels and enhancing maritime capabilities.

Key Features of the Deal

• Japan will supply three upgraded Mogami-class multi-role frigates to the Royal Australian Navy
• These ships will be constructed in Japan starting in 2029
• An additional eight frigates will be built in Australia

Strategic Significance

The agreement reflects Japan’s gradual shift away from its traditional post-war pacifist stance, as it expands defence cooperation beyond its long-standing alliance with the United States.

It also highlights:

• Strengthening of Australia–Japan security ties
• Focus on enhancing capabilities in the Indo-Pacific region
• Response to the growing influence and military presence of China

Operational DeploymentAustralia plans to deploy the frigates across the Indian and Pacific Oceans, regions witnessing increasing strategic competition and maritime activity.
