Ukrainian forces struck a Russian oil tanker on August 4 with a naval drone in the second attack on Russian ships in the Black Sea in two consecutive days.
The Moscow Times identified the tanker as the chemical tanker SIG, which is currently under US sanctions for supplying jet fuel to Russian forces in Syria.[1] Sources within the Ukrainian Security Service (SBU) confirmed to the Ukrainian outlet Suspilne that the SBU and the Ukrainian Navy struck the ship near the Kerch Strait Bridge using a naval drone.[2] The Russian Federal Agency for Sea and Inland Water Transport (Rosmorrechflot) reported that the strike on the SIG occurred 27 kilometers south of the Kerch Strait Bridge, and Russian milbloggers claimed that the attack caused Russian authorities to suspend traffic on the bridge.[3] Russian news aggregator Baza reported that the naval drone punched a two-by-one meter hole in the SIG’s engine room, and state Russian outlets claimed that the incident did not result in an oil spill.[4] A Russian milblogger claimed that the Ukrainian naval drone intentionally targeted the SIG’s engine room because targeting the stern creates the least likelihood of an oil spill and is where the most expensive and difficult-to-repair equipment is located.[5] The nature and location on the ship of the attack suggest that Ukrainian forces intended to disable the ship without generating significant ecological consequences. Ukrainian forces have long targeted the Kerch Strait Bridge in order to degrade Russian military logistics in southern Ukraine, and the attack on the SIG is likely part of a wider effort to disable ships involved in supplying Russian military forces and the location of the attack near the bridge suggests that it was part of a larger effort to disrupt Russian logistics along a key Russian ground line of communication (GLOC).

Ukrainian officials issued a notice to mariners that Ukraine may strike vessels near Russia’s Black Sea ports – a measured response to continued Russian strikes against Odesa – Ukraine's main port – since July 17. The Ukrainian State Hydrographic Service at the State Service of Maritime and River Transport posted a notice to mariners on August 4 announcing a “military threat” in the vicinity of the internal and external roadsteads at the ports of Taman, Anapa, Novorossiysk, Gelendzhik, Tuapse, and Sochi, until further notice.[8] The Ukrainian Ministry of Defense also cryptically tweeted ”Two can play that game,” without further context on August 5 - likely a reference to the Russian military’s continued strikes against Odesa’s port infrastructure since July 17.[9] This Ukrainian warning may deter merchant activity and international commercial shipping to and from Russia in the Black Sea.

Ukrainian naval strikes are likely part of a deliberate interdiction campaign aimed at setting favorable conditions for larger counteroffensive operations. A Ukrainian naval drone struck the Russian Olenegorsky Gornyak Ropucha-class landing ship on the night of August 3 to 4.[10] Ukrainian Main Military Intelligence Directorate (GUR) Representative Andriy Yusov stated on August 5 that the damage to the Olenegorsky Gornyak is very significant and suggested that the ship will not be operational for some time.[11] The UK Ministry of Defense (UK MoD) reported that images of the ship show it listing at 30 to 40 degrees, which suggests either that several watertight compartments were breached by the drone strike or that the crew’s efforts to control the damage were ineffective.[12] UK MoD reported that the Olenegorsky Gornyak is typically assigned to Russia’s Northern Fleet but has lately been ferrying military and civilian traffic between Russia and occupied Crimea following traffic disruptions to the Kerch Strait Bridge caused by previous Ukrainian strikes.[13] Previous Ukrainian interdiction efforts have mainly focused on Russian military targets on land, but it seems that Ukrainian forces are now expanding their efforts to include naval targets as part of these efforts. Ukrainian officials have repeatedly stated their commitment to a deliberate interdiction campaign against Russian military targets in order to degrade Russian logistics and defensive capabilities to set favorable conditions for future Ukrainian counteroffensive activity. Ukrainian forces are thus continuing to set conditions for future decisive operations via an interdiction campaign as they did before and during counteroffensive operations in Kharkiv and Kherson oblasts in 2022, now striking much deeper into Russian rear areas and incorporating maritime targets.

Ukrainian forces continue to draw Russian forces to the Bakhmut area and fix them there despite a slower tempo of Ukrainian operations there. Ukrainian offensive operations on Bakhmut’s southern and northern flanks have slowed in recent days, and Russian and Ukrainian sources did not report any Ukrainian ground attacks in the area on August 5.[15] The rate of Ukrainian advances in the Bakhmut area has also slowed in recent weeks. Ukrainian operations around Bakhmut have drawn additional Russian units and formations to the Bakhmut area and have kept Russian forces in the area, which was likely one of their primary objectives. Russian forces have deployed elite formations and units to support defensive operations around Bakhmut, including elements of the 98th Guards Airborne (VDV) Division, the 11th VDV Brigade, the 106th VDV Division, and the 364th Spetsnaz Brigade (Russian General Staff Main Directorate).[16] ISW has also observed speculation that elements of the 31st VDV Brigade are now defending Bakhmut’s southern flank and inconclusive footage suggesting that elements of the 150th Motorized Rifle Division (8th Guards Combined Arms Army, Southern Military District) recently arrived in the Bakhmut direction.[17] The arrival of these units and formations in the Bakhmut area represents the commitment of a sizable amount of combat power that Russian forces could otherwise have used to support offensive operations in Luhansk and Kharkiv oblasts or to reinforce Russian defensive operations in southern Ukraine.

Ukrainian counteroffensive operations also appear to be successfully fixing Russian forces in this area, as ISW has yet to observe elements of these forces deploying to other parts of Ukraine. Ukrainian Deputy Defense Minister Hanna Malyar stated on August 4 that Russian forces are continuing to commit a large number of forces in the Bakhmut direction in hopes of recapturing recently lost dominant heights north of Bakhmut City.

Ukrainian forces conducted limited ground attacks in southern Ukraine on August 5, part of a continuing pattern of limited Ukrainian ground attacks accompanying Ukrainian efforts to interdict Russian logistics and headquarters in rear areas. The Ukrainian General Staff reported that Ukrainian forces conducted counteroffensive operations in the Berdyansk (western Donetsk-eastern Zaporizhia Oblast area) and Melitopol (western Zaporizhia) directions. Russian sources claimed that Ukrainian forces conducted limited ground attacks in both areas and are advancing near Orikhiv.[19] Russian sources have routinely characterized Ukrainian attacks in southern Ukraine as up to a company in size with minimal armored vehicle or tank support.[20] These small Ukrainian ground attacks indicate that Ukrainian forces are continuing to conserve uncommitted reserves for larger mechanized attacks. Limited Ukrainian ground attacks can set conditions for larger mechanized attacks when the Ukrainian deep interdiction campaign has generated effects on the battlefield and can also support Ukrainian efforts to achieve an asymmetrical attrition gradient. Larger Ukrainian mechanized offensive operations have been sporadic since the start of the counteroffensive in early June, and ISW did not observe visual evidence or other observable signatures indicating a large assault near Orikhiv that Russian sources claimed occurred on July 26.[21] Russian sources may have exaggerated the Ukrainian attack in order to portray the Ukrainian counteroffensive operations as a failure. The New York Times reported that two anonymous Pentagon officials said on July 26 the ”main thrust” of the counteroffensive had begun, although it was not clear if those officials were referring to the July 26 attack, and other unnamed US officials subsequently walked those comments back.[22] Ukrainian forces are clearly not committing to large, massed mechanized counteroffensive operations in the Zaporizhia direction as their interdiction campaign proceeds, although they continue to conduct a series of variously-sized but relatively small attacks across the front line that are having the effects of fixing Russian forces in place, tiring them, and attriting them, as ISW has previously observed.

Senior officials from reportedly 40 countries, including the US, China, and India, began talks in Jeddah, Saudi Arabia on August 5 aimed at drafting a set of key principles to guide the future settlement of the war in Ukraine. US National Security Spokesperson John Kirby stated on August 3 that the White House does not expect any “tangible deliverables” from the talks in Saudi Arabia and that the talks are a continuation of the process to promote a peace formula proposed by Ukrainian President Volodymyr Zelensky.
