Australia and Britain have announced plans to formalize a bilateral treaty for producing a new class of nuclear-powered submarines under the AUKUS defense partnership, which also includes the United States. This development is expected to further strengthen military collaboration between the three nations and enhance security in the Indo-Pacific region.
The AUKUS pact, first revealed in 2023, includes Australia’s acquisition of U.S. Virginia-class nuclear submarines within the next decade. Following this, Britain and Australia will cooperate in building a new class of submarines, with construction taking place at Barrow-in-Furness, England, and South Australia. This initiative is part of a broader effort to improve defense capabilities in response to rising geopolitical tensions.
Australian Defense Minister Richard Marles confirmed the start of treaty negotiations after a meeting in London with British and American defense officials. Marles explained that the treaty will focus on industrial cooperation and the transfer of advanced technology, ensuring that both Britain and Australia will operate the same class of submarines. He emphasized the importance of these collaborative efforts to successfully carry out the project.
British Defense Secretary John Healey added that during the meeting, AUKUS defense ministers also agreed to equip P-8A Maritime Patrol Aircraft with British-made Stingray torpedoes. These aircraft, which are used for submarine hunting, will be deployed in the Indo-Pacific region to bolster maritime security.
U.S. Defense Secretary Lloyd Austin highlighted the growing cooperation between the AUKUS nations, noting that they had conducted a series of experiments across various domains, including ground, undersea, and electromagnetic spectrum operations. These efforts aim to improve the military capabilities of the three countries under the second pillar of the AUKUS partnership, which focuses on advanced technology sharing.
The AUKUS alliance has also committed to increasing its work on hypersonic technology, both for offensive and defensive purposes. A joint statement from the defense ministers confirmed that the three nations are working together to develop and implement these technologies. A large-scale drone exercise is planned for later this year, further demonstrating the partners’ commitment to modernizing their defense strategies.
This shift toward a more robust defense posture comes amid growing tensions in the Indo-Pacific. As China expands its influence and military presence in the region, countries have sought greater defense cooperation. The AUKUS pact, with its focus on nuclear-powered submarines and technological collaboration, is seen as a direct response to these challenges.
The industrial and technological collaboration between Australia, Britain, and the United States is a central aspect of the AUKUS initiative. Marles emphasized that the treaty will outline how these mechanisms will operate, ensuring the smooth production of submarines and the sharing of advanced technologies. Once operational, these submarines will provide a long-range, stealthy presence in strategic waters, enhancing deterrence and defense in the region.
Healey also pointed out that the integration of British-made Stingray torpedoes into the P-8A aircraft is one example of the practical defense cooperation between AUKUS partners. These aircraft, already in use by the U.S. and Australia, will be equipped with advanced capabilities to counter underwater threats in the Indo-Pacific.
The AUKUS partnership continues to evolve, with the upcoming large-scale drone exercise signaling the nations’ dedication to staying ahead of technological advancements. As they collaborate to develop hypersonic technology and other modern warfare capabilities, the AUKUS alliance is positioned to play a key role in maintaining stability and security in the Indo-Pacific region.
