The Ukrainian underwater drone attacked a Russian submarine. According to the SBU, this marked the first operation of its kind in history. The attack led to an explosion in the port of Novorossiysk, although Russian official sources are trying to refute this information.
Satellite photographs showed damage to the pier, indicating serious consequences of the attack. Russia has taken new security measures, but this did not stop the Ukrainian drone. The special operation was successful due to detailed planning and careful development.
The Russian submarine that was attacked is worth over 400 million dollars. It was successfully destroyed following previous operations of Ukrainian drones at sea.
