Ukraine attack on Sevastopol damages ship and submarine

 ISW:

Ukrainian 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.[1] 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.[2] 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.[3] Geolocated footage published on September 13 shows explosions at the dry dock in the Sevastopol port.[4] 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.[5] 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.[6] 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.

The loss of the naval assets could have a long-term impact on Russian operations, although this war has been mainly an infantry and air assault conflict. Ukraine media reports that the landing ship Minsk is damaged beyond repair:

Krymskii Veter posted a photo that was taken at the dry dock of Sevastopol’s Ship Bay and sent to the channel by a follower.

The Minsk, a military landing ship of Russia’s Black Sea Fleet, has been damaged so badly that it is beyond repair.
...

The assumption that the Rostov-on-Don submarine will be now permanently disabled is based not only on the scale of the fire that engulfed the dry dock, where the submarine was located together with the Minsk landing ship, but also on the likely use of a Storm Shadow cruise missile, which can effectively burn ships from the inside.

The report says that the members of the underground resistance movement have been actively working to identify important military targets of the Russians over the past week. The movement also thanked Sevastopol residents who send data, photos and coordinates with valuable information on a daily basis.

"Agents from various fields were involved: civilians, military personnel of the Russian Black Sea Fleet and employees of the repair plant (the last stage of repair of one of the targets was held there).

This appears to be in response to Ukraine's breakthrough of the Russian first line of defense where Russia had spent 60 % of its time preparing to defend.

According to Mysiagin, the Russian forces assumed their troops were Ukrainians attempting to recapture territory near the Donetsk airport. The rushed exit caused the soldiers to endure friendly fire from their own artillery, Mysiagin added.

"The result was 27 dead and 34 wounded. Approximately half of the wounded had their arms or legs blown off," Mysiagin said. "Several pieces of equipment were lost."
