Australia selects Japan’s Mogami-class frigates for its naval fleet
- The Royal Australian Navy has selected Japan's Mogami-class multi-role frigate design, marking a major milestone for Japanese defense exports.
- The selection represents the first time Japan has exported lethal military equipment since easing the three principles governing its arms transfer policy.
- The Mogami design originated under the 2013 national defense strategy to handle undefined security challenges, such as regional maritime expansion and gray-zone scenarios.
The Royal Australian Navy has selected Japan’s Mogami-class multi-role frigate design, marking a major milestone for Japanese defense exports. Australia chose the stealthy, reduced-crew warship over competing bids from Germany, South Korea, Spain, and other nations following an evaluation process finalized in August 2025.
Export Breakthrough for Japanese Defense Policy
The selection represents the first time Japan has exported lethal military equipment since easing the three principles governing its arms transfer policy. Defense officials in Tokyo noted that the transaction has generated significant international interest. New Zealand is also reportedly considering acquiring the advanced FFM-series vessels. Japan’s defense cooperation strategy relies heavily on the versatility and cost-effectiveness of these ships, which are designed to interact closely with the United States Navy.
Strategic Evolution From Gray Zone Security to High-Intensity Conflict
The Mogami design originated under the 2013 national defense strategy to handle undefined security challenges, such as regional maritime expansion and gray-zone scenarios. The Japan Maritime Self-Defense Force initially sought to replace minesweepers with versatile escort vessels to maintain continuous peacetime surveillance without straining fleet size. Subsequent defense reviews in 2018 and 2022 shifted priorities toward high-intensity conflict capabilities. Consequently, Japan adjusted its acquisition plans, reducing the original 22 Mogami units to 12 while ordering 12 upgraded FFM-series ships beginning in 2023.
Broadening Regional Defense Cooperation
An unnamed high-ranking defense official under the government of Sanae Takaichi noted that Japan historically relied on domestic efforts and its U.S. alliance for 95 percent of its defense. In light of rising regional uncertainties regarding Washington’s commitments, Tokyo is actively expanding cooperation with allied nations. The FFM frigate series underpins this new industrial and diplomatic direction, allowing Japan to strengthen collective security partnerships while maximizing its limited domestic defense resources.
