Ukraine tried for the first time to use uncrewed surface vessels against Russian vessels in Sevastopol Bay in September 2022, but 70 kilometres from the target, the connection with billionaire Elon Musk's Starlinks was lost. It was not possible to persuade Musk to turn back on the connection, so Ukraine modified the drones.
Details: The first attempt to attack Russian targets in Sevastopol took place on the night of 16-17 September 2022.
