The Royal Navy has received XV Excalibur, the UK’s first extra-large uncrewed submarine, following a series of long-range control demonstrations and a world-first quantum navigation trial. The 12-metre, 19-tonne vessel will undergo two years of sea testing as the UK expands autonomous undersea capabilities under Project Cetus and wider defence initiatives.
