title: Ukraine: how uncrewed boats are changing the way wars are fought at sea
abstract: When Ukraine successfully deployed self-driving “drone” boats for a major attack on the Russian navy at Sevastopol in Crimea in September 2022 it was a defining moment that changed the future of naval warfare. Uncrewed surface vessels (USVs) have been used before, but this was the first instance of multiple, armed USVs, used simultaneously in combination with aerial drones for a successful, offensive naval operation on a military target.
