Ukraine Sinks Russian Submarine in Port with Underwater Drone

Ukraine has successfully attacked a Russian submarine using a new underwater drone. The strike happened at the Russian naval base in Novorossiysk on the Black Sea. This is the first reported use of such a weapon in the war. It marks a major shift in naval warfare. The drone, called "Sub Sea Baby," targeted the submarine while it was docked at a heavily guarded pier. Russian defenses are primarily designed to detect threats on the surface or in the air. The underwater drone exploited this weakness. The attack proves that Ukrainian forces can now strike Russian warships even in their home ports. Military analysts say it shows that no Russian naval asset in the Black Sea is safe. This new capability puts more pressure on Russia's Black Sea Fleet. It has already been forced to move some ships away from Crimea after several Ukrainian missile and sea drone attacks.
