Historic First: Japan to Export Destroyers to Australia

In a landmark move, Japan has announced its intention to export destroyers to Australia for the first time in its history. This decision marks a significant shift in Japan's defense policy and international relations.


According to reports from Japanese media, the Japanese government will be selling the 'Mostami' class destroyers to Australia. This is the first instance of Japan exporting a large-scale military asset to a foreign nation, and the second time it has exported any finished military equipment. Previously, Japan had only exported early warning radar systems to the Philippines.


Australia has already confirmed its interest in the 'Mostami' class, which was developed by Japan as part of its modern naval fleet. In February 2024, Australia announced a plan to purchase 11 general-purpose destroyers, with bids coming from Japan, Spain, South Korea, and Germany. Australia's Deputy Prime Minister and Minister for Defence, Richard Marles, stated that Japan has been selected as the most viable partner for joint development, and negotiations will be prioritized.


The 'Mostami' class destroyers are among Japan's newest naval vessels, with a standard displacement of 3,900 tons and a full load displacement of 5,500 tons. They are 132.5 meters long, 16.3 meters wide, and can reach a maximum speed of 30 knots. These destroyers are designed with stealth technology and are equipped with a variety of weapons systems, including main guns, vertical launch systems, anti-ship missiles, close-in weapon systems, and helicopter decks. They are capable of performing a wide range of naval operations.


Japan's participation in Australia's naval tender is based on the 'Mostami' class design. This move reflects Japan's growing ambition to expand its military exports and strengthen its strategic partnerships in the Indo-Pacific region.


In response to Japan's increasing military exports, Chinese officials have expressed concerns, noting the historical context of Japan's militaristic past and urging the country to respect the security concerns of its neighbors and to continue its path of peaceful development.


This development is likely to have far-reaching implications for regional security dynamics and international defense cooperation. As Japan steps further into the role of a global defense exporter, its relationships with countries like Australia will become increasingly important in shaping the future of the Indo-Pacific region.
