September 13, 2023 - ISW PressUkrainian forces conducted missile strikes on occupied Sevastopol, Crimea, on September 13, damaging a Russian landing ship, a Kilo class submarine, and port infrastructure. The Department of Strategic Communications of the Ukrainian Armed Forces stated that Ukrainian forces successfully conducted missile strikes on Russian naval means and port infrastructure in occupied Sevastopol. Main Military Intelligence Directorate (GUR) Spokesperson Andriy Yusov stated that the missiles struck the Russian state-owned ship repair facility Sevmorzavod, damaging repair facilities as well as a landing ship and a submarine, both of which he described as unrecoverable. The Russian Ministry of Defense (MoD) claimed that Russian air defenses intercepted seven out of 10 Ukrainian cruise missiles targeting the Sevmorzavod ship repair facility but acknowledged that Ukrainian missiles struck two ships under repair. Geolocated footage published on September 13 shows explosions at the dry dock in the Sevastopol port. Satellite imagery published on September 12 shows one Ropucha class landing ship and one Kilo class submarine at the dry dock, and satellite imagery published on September 13 shows that the Ukrainian missile strike likely destroyed the two vessels. Ukrainian Southern Operational Command Spokesperson Captain First Rank Nataliya Humenyuk stated that there were no Russian missile carriers present during the strike but noted that Ukrainian intelligence is still unaware of which submarine was at the dry dock. The apparent destruction of the two vessels will likely render the dry dock inoperable until Russian forces can clear the debris, which may take a significant amount of time. The extent of the damage to Sevmorzavod’s repair facilities beyond the dry dock is unclear, and any damage to one of the Russian Black Sea Fleet’s main repair facilities in occupied Crimea will likely have reverberating impacts in the event of further Ukrainian strikes on Russian naval assets.
