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. 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.

Russian insider sources claimed that the Kremlin’s inner circle is again actively disagreeing about the necessity of and preparations for a second wave of reserve mobilization ahead of the semi-annual fall conscription cycle, which starts on October 1. A Russian Telegram channel with alleged connections to Russian security sources claimed that select Russian officials are “seriously” preparing for a second wave of reserve mobilization and are hoping to conduct another reserve mobilization wave in the fall. It is important to distinguish between Russia’s normal semi-annual conscription callup, a large-scale reserve mobilization like the one that brought more than 300,000 reservists into the Russian armed forces in Fall 2022, crypto-mobilizations that bring reservists into the force at lower numbers over a long period of time, and various efforts to encourage or coerce Russians to sign ostensibly voluntary contracts with the Russian military. The channel claimed that Russian officials want to mobilize between 170,000 to 175,000 reservists and move the fall conscription date from October 1 to November 1 to accommodate a reserve mobilization processes, while simultaneously conducting “contract mobilization” to recruit an additional 130,000 personnel for contract service using coercive measures. The channel claimed that a powerful group of “siloviki hawks” is also proposing stricter reserve mobilization measures such as restricting certain individuals from obtaining mobilization deferrals, which has sparked major disagreements with officials in the Russian Presidential Administration. The channel claimed that the Presidential Administration fears a response to such measures from other Russian officials and broader Russian society.

Ukrainian forces continued counteroffensive operations in Donetsk and Zaporizhia oblasts on September 11 and have reportedly advanced near Bakhmut and in western Zaporizhia Oblast. Ukrainian military officials announced on September 11 that Ukrainian forces have liberated 2 square kilometers of territory in the Bakhmut direction over the past week and have made gains near Klishchiivka (6km southwest of Bakhmut) and Andriiivka (9km southwest of Bakhmut). Ukrainian Deputy Defense Minister Hanna Malyar also stated that Ukrainian forces have gained a total of 4.8 square kilometers in the Tavriisk (Zaporizhia) operational direction over the past week, particularly south of Robotyne (10km south of Orikhiv) and west of Verbove (20km southeast of Orikhiv).

Ukrainian forces continued to advance south of Robotyne in western Zaporizhia Oblast and reportedly advanced near Bakhmut on September 10. Geolocated footage posted on September 10 shows that Ukrainian forces have advanced east of Novoprokopivka (18km southeast of Orikhiv). Ukrainian Tavriisk Group of Forces Spokesperson Oleksandr Shtupun noted that Ukrainian forces continue to advance near Robotyne (12km south of Orikhiv) and have liberated 1.5 square kilometers of territory in this direction. The Ukrainian General Staff and Ukrainian Eastern Group of Forces Spokesperson Ilya Yevlash reported that Ukrainian forces achieved unspecified success near Klishchiivka (7km southwest of Bakhmut) in Donetsk Oblast.

Ukrainian forces made confirmed advances in the Donetsk-Zaporizhia Oblast border area and in western Zaporizhia Oblast and made claimed advances south of Bakhmut on September 9. Geolocated footage published on September 9 shows that Ukrainian forces advanced northwest of Novomayorske (18km southeast of Velyka Novosilka) along the Donetsk-Zaporizhia Oblast border, where Russian sources claim fighting has intensified in recent days. Additional geolocated footage published on September 9 shows that Ukrainian forces also advanced northeast and east of Novoprokopivka (13km south of Orikhiv) and west of Verbove (20km southeast of Orikhiv) in western Zaporizhia Oblast. The Ukrainian General Staff reported that Ukrainian forces achieved unspecified successes south of Robotyne (10km south of Orikhiv). A Kremlin-affiliated Russian milblogger claimed that Ukrainian forces forced Russian forces to withdraw from Andriivka (9km southwest of Bakhmut), and another prominent milblogger claimed that Andriivka is now a contested “gray zone.” Ukrainian officials reported that Ukrainian forces also achieved unspecified success south of Klishchiivka.

Russian forces have reportedly made notable changes to their command and control (C2) in Ukraine to protect command infrastructure and improve information sharing, although Russian force deployments are likely still exacerbating issues with horizontal integration. Center for Security and Emerging Technology (CSET) Deputy Director of Analysis Magarita Konaev and CSET Fellow Owen Daniels stated on September 6 that Russian forces moved headquarters out of range of most Ukrainian strike systems and have placed forward command posts further underground and behind heavily defended positions. It is unclear if Russian forces have employed this more protected command infrastructure throughout Ukraine and to what degree these defensive efforts have impeded Ukraine’s ongoing interdiction campaign. Konaev and Daniels stated that Russian forces have improved communications between command posts and units at the front by laying field cables and using safer radio communications. The Royal United Services Insitute (RUSI) stated on September 4 that Russian forces are also trying to improve signals through the wider use of application-based C2 services that require less training. Konaev and Daniels noted that signals at the battalion level downward are still often unencrypted and that Russian personnel still frequently communicate sensitive information through unsecure channels.

Ukrainian forces continued offensive operations near Bakhmut and in western Zaporizhia Oblast on September 7 and made further gains on both sectors of the front. Geolocated footage published on September 7 indicates that Ukrainian forces have made further advances northwest of Verbove (18km southwest of Orikhiv) in western Zaporizhia Oblast. A prominent Russian milblogger claimed that Ukrainian forces made further advances in the area and other milbloggers claimed that Ukrainian forces temporarily advanced to the northwestern outskirts of Verbove on September 6, likely indicating further recent Ukrainian advances northwest of the settlement. Satellite imagery collected on September 6 shows burning foliage in a tree line roughly a kilometer northwest of Verbove, suggesting that Russian forces are firing on advancing Ukrainian forces in the area. Geolocated footage published on September 7 indicates that Ukrainian forces have made marginal gains northwest of Klishchiivka (7km southwest of Bakhmut). The Ukrainian General Staff reported that Ukrainian forces achieved unspecified successes south of Bakhmut and near Robotyne (10km south of Orikhiv) and Verbove in western Zaporizhia Oblast.

Ukrainian forces continued counteroffensive operations in the Bakhmut and western Zaporizhia Oblast directions and have made gains in western Zaporizhia Oblast as of September 6. Geolocated footage shows that Ukrainian forces have advanced along the trench line west of Verbove (about 20km southeast of Orikhiv), and the Ukrainian General Staff stated that Ukrainian forces achieved unspecified successes in the Robotyne—Novoprokopivka direction south of Orikhiv. The Ukrainian General Staff additionally reported that Ukrainian forces are continuing successful offensive operations south of Bakhmut.

Ukrainian light infantry has advanced to positions beyond anti-tank ditches and dragon’s teeth anti-tank obstacles that comprise the current Russian defensive layer ahead of the Ukrainian advance in western Zaporizhia Oblast, and Ukrainian forces likely intend to hold those positions. ISW is not prepared to assess that Ukrainian forces have breached this Russian defensive layer in the absence of observed Ukrainian heavy equipment in these areas. Geolocated footage published on September 4 indicates that Ukrainian forces advanced to tree-line positions that are east of the Russian anti-tank ditches and dragon’s teeth obstacles that are a part of a tri-layered defense immediately west of Verbove (18km southeast of Orikhiv). Geolocated footage published on September 4 indicates that Ukrainian light infantry has also advanced further into a series of prepared Russian defensive positions along the road that runs northwest into Verbove. Other geolocated footage published on September 4 indicates that Ukrainian forces have advanced up to Russian defensive positions between Robotyne (10km south of Orikhiv) and Novoprokopivka (13km south of Orikhiv). Ukrainian forces are widening the breach they have already made in one Russian defensive layer and are reportedly maneuvering more equipment and personnel into tactical rear areas of this layer. Ukrainian forces appear to be making gains in the immediate vicinity of the not-yet-breached Russian defensive layer that runs northwest of Verbove to north of Solodka Balka (20km south of Orikhiv) with infantry assaults and heavy artillery fire on Russian positions further into and south of this layer. The deployment of Ukrainian heavy equipment and more substantial forces to these areas than ISW has so far observed would indicate both a breach of this Russian defensive layer and an effort to widen that breach.

Ukrainian military officers offered notably frank and direct commentary about the prospects of further Ukrainian advances in western Zaporizhia Oblast and indicated that the series of prepared Russian defensive positions immediately ahead and further south of the Ukrainian advance may be less challenging to Ukrainian forces. Ukrainian Tavriisk Group of Forces Commander Brigadier General Oleksandr Tarnavskyi, who commands the Ukrainian grouping in southern Ukraine, discussed Ukraine’s counteroffensive in an interview with The Guardian on September 2. Tarnavskyi stated that Ukrainian forces have decisively breached Russian forces’ “first line of defense” and that he expects faster Ukrainian gains as Ukrainian forces press on a weaker “second line” of defense. Ukrainian forces have advanced up to the next series of prepared Russian defensive positions in certain areas in the Robotyne area in western Zaporizhia Oblast, although many Russian sources assert that these positions are the first, not the second, defensive layer in a multi-echeloned Russian defense in southern Ukraine. Ukrainian officials and Russian milbloggers are using different terminology to describe the same positions. Russian sources characterize the first series of positions that Ukrainian forces have previously breached as a forward line without giving it an ordinal number, and the series Ukrainian forces are currently approaching as the first main line of defenses — while Ukrainian forces characterize these positions as Russia’s second line of defenses.
