The Aukus alliance members — Australia, the United Kingdom, and the United States — announced Saturday that they will develop advanced underwater drone systems and further deepen their maritime relationship, which will see American submarines stationed in Australia by next year.
New agreements on underwater drones
The agreements, announced in Singapore by the defense ministers of the three countries, include investing in the development of systems and weapons for uncrewed undersea vehicles (UUVs). The initiative aims to deliver a suite of highly adaptable multi-mission UUV payloads designed to support undersea operations and maintain the collective advantage in the maritime domain, according to U.S. Defense Secretary Pete Hegseth.
While Hegseth did not provide specific details about the systems, which are generically termed 'payload and effectors,' U.K. Defense Secretary John Healey emphasized that the collaboration would rapidly provide forces with the most advanced battlefield technologies. He stated that the partnership would produce a range of cutting-edge sensors and weapons systems for undersea drones.
Submarine rotations on track
Hegseth, Healey, and Australian Defense Minister Richard Marles also confirmed that U.S. submarine rotations are on schedule to begin by the end of next year at HMAS Stirling in Western Australia. This development is part of the broader Aukus defense accord signed in 2021 under former President Joe Biden. After a review by the Trump administration last year, the U.S. reiterated its commitment to the project.
Under Pillar One of Aukus, the U.S. is to sell Australia three of its nuclear-powered Virginia-class submarines, and all three nations will collaborate to design and build new submarines over the coming decades. Pillar Two focuses on sharing advanced technology, including quantum computing, artificial intelligence, and advanced weaponry.
Streamlined submarine purchase plans
The new agreement announced Saturday includes a plan to streamline Australia's submarine purchase plans by limiting them to in-service ships, rather than the earlier planned mix of used and new vessels. An Australian government official noted that this decision will simplify training, maintenance, and supply chains if the U.S. submarines are all the same variant. Canberra also retains the option to purchase up to two additional submarines if needed, similar to the original agreement.
The Aukus alliance continues to strengthen maritime security in the Indo-Pacific region, with the latest advancements in underwater drone technology expected to enhance the collective capabilities of the three nations.
