The United Kingdom has carried out the first-ever test launch of a heavyweight torpedo from an unmanned underwater vehicle. According to The i Paper, as cited by RBC-Ukraine, the tests took place last week in British waters and were conducted under the AUKUS defense partnership, which brings together the UK, the United States, and Australia. London officially called the launch a "significant breakthrough" for Euro-Atlantic security and the development of NATO's underwater capabilities.
Test Details and the Excalibur Vehicle
The torpedo, jointly developed by the United States and Australia, was launched from the 12-meter Excalibur unmanned underwater vehicle, built in Plymouth. This weapon is designed to strike surface ships and deep-diving submarines. Until now, similar torpedoes had only been launched from crewed submarines, whereas the recent test confirmed their launch from an uncrewed platform. Excalibur belongs to the class of extra-large unmanned underwater vehicles and is currently undergoing a series of sea trials as part of the British program to develop autonomous underwater technologies.
Transatlantic Coordination under AUKUS
The test was part of AUKUS's broader work on developing autonomous systems and new underwater warfare capabilities. Notably, in previous trials, Excalibur had already been remotely controlled from Australia, located more than 10,000 miles from Plymouth, demonstrating the maturity of the telemetry and command channels for controlling extra-large unmanned underwater vehicles. The joint development of the torpedo by American and Australian specialists and its launch from a British platform underscore the level of technological integration among the three alliance members.
Strategic Context and Protection of Underwater Infrastructure
The development of such technologies is directly linked to the task of protecting Britain's underwater infrastructure, including submarine cables and pipelines. London cites threats from hostile states and the need to strengthen control over critical objects on the seabed. In this context, autonomous underwater vehicles capable of carrying heavy weapons are seen as a tool for deterrence and the security of underwater communications.
Related Autonomous Systems Developments
In parallel with its underwater programs, Britain is also advancing land-based autonomous solutions: General Dynamics Land Systems-UK and ARX Robotics UK have joined forces to develop autonomous support technologies, which are planned to be integrated into the Ajax armored vehicle. The totality of these initiatives points to London's systematic course on deploying unmanned platforms across various branches of the armed forces and areas of defense.
