The U.S. Navy demonstrated its advanced AN/BYG-1 submarine combat control system to United Kingdom sailors and industry representatives as part of the AUKUS trilateral security partnership. The system, developed through a joint U.S.–Australian program, is currently operated by both nations’ submarine forces.

The demonstration supports plans to integrate AN/BYG-1 into the future SSN-AUKUS submarines, which will be designed by the United Kingdom and built and operated by the Royal Navy and the Royal Australian Navy. The U.S. Navy said incorporating the system into the baseline design underscores the interoperability of the three nations’ attack submarine fleets.

The U.S. Navy said Australia’s acquisition and operation of nuclear-powered attack submarines under AUKUS Pillar I directly supports U.S. and allied efforts to maintain a favorable balance of power in the Western Pacific. The AUKUS Integration and Acquisition program office within the Department of the Navy is responsible for executing the partnership, with a focus on interoperability, sustainment infrastructure, and the highest standards of nuclear stewardship and nonproliferation.
