The prestigious Russian Navy base at Kronstadt, near St. Petersburg, came under Ukrainian drone attack overnight, in what may well be the first strike of its kind against the Baltic Fleet. Ukrainian drones targeted the naval base, including the Project 20380 Steregushchiy class corvette Boikiy, highlighting the fact that Russian warships are vulnerable even when hundreds of miles from Ukraine’s borders.
According to the official account of the Ukrainian 414th Separate Unmanned Strike Aviation System Brigade on X, the corvette was set ablaze while in the Veleshchynskyi dry dock in Kronstadt, where it is said to have entered scheduled maintenance in February of this year. The same account posted a video showing the attack. While we are used to kamikaze drone video feeds cutting out just before detonation, the fact that multiple drones were involved means we can see the burning vessel from several angles.
Reportedly, the drones that hit the corvette were from the 1st Separate Center of Ukraine’s Unmanned Systems Forces. Considering the long distance to the target, it is interesting to note that video from the seekers was available. This indicates that either a local operator on the ground was involved in targeting and recording the feed, or otherwise a satcom link was used to do the same. While it is conceivable that the drones used autonomous guidance, they would still have needed someone nearby or connected via satcom to record the seeker’s view. Another possibility is that shorter-range drones were used for the attack, something that Ukraine has done before for attacks deep in Russia, although this seems less likely here.
Ukraine’s Unmanned Systems Forces stated that the Boikiy was involved in escorting ships associated with Russia’s so-called shadow fleet, the collection of older tankers operating under foreign flags that Moscow relies on to export oil despite Western sanctions. According to Ukrainian officials, Russia has increasingly tasked Baltic Fleet vessels with escort, monitoring, and security missions for these tankers as they transit the Baltic Sea carrying sanctioned Russian oil to markets prepared to bypass Western restrictions.
The Steregushchiy class ships are among Russia’s more modern corvettes. With a standard displacement of 1,800 tons, a length of 343 feet, and a flight deck for a helicopter, the corvettes are closer to frigates, according to some classification systems. Their primary armament consists of two quadruple launchers for Uran anti-ship missiles, a 12-cell Redut vertical launch system for various air defense missiles, and two quadruple tubes for Paket-NK anti-torpedo/anti-submarine torpedoes.
