Footage of an attack by Ukrainian naval drones on the Russian missile boat "Ivanovets" of project 12411. As can be seen in the video, the ship was attacked by several naval drones, probably about four, they were coming from different directions. The crew fired at the drones, but the available defenses on the ship were not enough to repel the attack. The video shows that the ship is being attacked at the location of anti-ship missiles and at the stern; one hole under the missiles is already on board. After several attacks, the ship tilted on one side and after another blow, a powerful explosion occurred on the ship. As shown in the video, the ship eventually sank. Judging by all the attacks of sea drones, equipment equipped with machine guns on ships is clearly not enough to protect against drone attacks, we need to look for other solutions.
