A naval drone struck the Russian boat "Sobol"; the crew was killed
According to reports, the entire crew of the Russian FSB Border Service’s PSKA-300-class patrol boat *Sobol* was killed in a strike by a Ukrainian naval drone. The incident occurred on April 30 during the deployment of naval drones in the vicinity of the Kerch Bridge.

On the night of April 30, the Ukrainian Navy struck two Russian boats that were guarding the Kerch Bridge.
The Navy confirmed at the time that one of them was indeed the FSB’s “Sobol” boat, while the second vessel struck was a “Grachonok”-class boat, whose crew also perished.
These very boats were responsible for security in the waters around the illegally constructed bridge connecting the temporarily occupied Crimea with Russian territory.
The Project 12200 high-speed patrol boat “Sobol” was developed by the Almaz Design Bureau to intercept violators and protect territorial waters in the coastal zone.
To achieve speeds of up to 48 knots, the boat is equipped with an automated trim control system that dynamically adjusts the vessel’s trim.
Its armament includes a 14.5-mm machine gun mount, and its fuel supply ensures a three-day endurance. Russia’s FSB had 11 such boats in the Black Sea-Azov Sea basin.
