The Royal Navy conducted Exercise REPMUS, focusing on anti-submarine warfare (ASW) with NATO allies off Portugal's coast. Approximately 200 personnel participated, testing various uncrewed and autonomous technologies to enhance ASW capabilities and underwater infrastructure surveillance. The exercise allowed for the evaluation of emerging technologies that may inform future operations under the Atlantic Bastion program, initiated in December 2025. The Royal Navy deployed underwater gliders and uncrewed surface vessels (USVs) to gather acoustic data and track potential threats. Notably, two types of USVs measuring 12 and 17 meters were tested, capable of towing sonar systems and launching gliders. This exercise reflects the Royal Navy's transition to a hybrid navy amidst growing concerns over Russian underwater activity.
