Ukraine's state security service has unveiled an upgraded sea drone it says can now operate anywhere in the Black Sea, carry heavier weapons and use artificial intelligence for targeting. Ukraine has used the unmanned naval drones to target Russian shipping and infrastructure in the Black Sea. The Security Service of Ukraine, known by its Ukrainian acronym SBU, has credited strikes by the unmanned vessel known as the “ Sea Baby" with forcing a strategic shift in Russia’s naval operations.
