The Security Service of Ukraine (SBU) successfully disabled a Russian Varshavianka-class submarine in Novorossiysk port using the underwater drone Sub Sea Baby. This submarine, capable of launching Kalibr cruise missiles used in attacks against Ukraine, is now effectively out of service. The attack was a joint operation between the 13th Main department of counterintelligence of SBU and the Ukrainian Navy. The estimated cost of this type of submarine is around $400 million, with potential construction costs now reaching $500 million due to international sanctions.

Russia attacks two Ukrainian ports, damaging three Turkish-owned vessels, and it seems like the situation is getting even more complicated than it already was. You know, you can’t help but feel a certain sense of inevitability about these kinds of events, almost as if they were pre-ordained. The fact that the strikes happened after a phone call between Putin and Erdoğan just a few hours earlier definitely raises eyebrows. It feels like a calculated move, a statement being made, but the exact message is still a little fuzzy, isn’t it?
Turkey’s reaction, or perhaps lack thereof, is something that’s drawing a lot of speculation.… Continue reading
On Wednesday, Ukrainian forces utilized naval drones to strike the oil tanker Dashan, identified as part of Russia’s “shadow fleet” in the Black Sea, causing critical damage and potentially disabling the vessel. This attack, carried out in coordination with the Ukrainian navy, marks the third such strike in two weeks, demonstrating a strategic shift toward targeting ships at sea alongside land-based energy infrastructure. The $30 million tanker, which was sailing with its transponder off, has been sanctioned by several Western countries and the EU for its role in Russian oil exports. This action is part of Ukraine’s ongoing efforts to disrupt Russia’s energy revenue, a critical source of funds for its war efforts.

The tanker Kairos, identified as part of Russia’s shadow fleet, is stranded off Bulgaria’s Black Sea coast due to rough weather preventing authorities from boarding. The ship, which entered Bulgarian waters after being released by a Turkish tugboat, is currently empty and poses no immediate environmental threat. While the crew of ten is safe and in contact with officials, surveillance continues using radar and thermal cameras. Diplomatic efforts are underway to determine the vessel’s purpose, with plans to tow the tanker to a safe harbor once conditions improve.

Adding to a series of recent maritime incidents, a Russian-linked tanker, the Midvolga 2, was struck in the Black Sea on Tuesday while en route from Russia to Georgia, carrying sunflower oil. This marks the fourth such attack in a week, following the bombing of the Mersin off the coast of Senegal and the attacks on the Kairos and Virat near the Bosphorus. While the crew was unharmed and the Midvolga 2 is heading to Turkey, the attacks have been linked to Ukrainian drone strikes targeting vessels suspected of circumventing sanctions against Russia.

Overnight, Ukrainian forces launched coordinated strikes against targets in southwestern Russia, including a key oil tanker loading terminal in Tuapse via kamikaze drones and robot boats. The attack resulted in explosions and fires within the port area, despite Russian claims of interception and minimal damage. Simultaneously, Ukrainian drones targeted railroad infrastructure in Rostov, prompting air travel disruptions and reports of damage, alongside an extensive drone campaign against Russian energy infrastructure. These attacks are part of a broader strategy aimed at disrupting Russian oil exports and retaliating for Russian attacks on Ukrainian civilian infrastructure, with a notable increase in strikes against power grids and heating plants.

The Ukrainian Navy successfully employed a suicide drone to strike an elite Russian special forces unit on the Sivash drilling rig in the Black Sea, which Russia had seized in 2014 and equipped with surveillance systems. Following the strike, Russian propagandists attempted to portray the incident as a victory, while the Ukrainian HUR destroyed Russian air defense facilities in occupied Crimea, including a S-400 Triumph air defense control point and radar systems. Espanyola, a Russian naval detachment formed in 2024 with ties to private military companies, was also operating in the area near the rigs. The Ukrainian military continues to carry out special operations in the area.
