Ukrainian forces reportedly struck Russian naval assets in a drone attack on Novorossiysk Bay on March 4, 2026, damaging a frigate and a patrol boat, according to open-source intelligence (OSINT) analysts. The attack, which targeted the port city in southern Russia, underscores the escalating maritime dimension of the ongoing conflict and Kyiv’s ability to reach targets within Russian-controlled territory. The incident highlights the vulnerability of Russia’s Black Sea Fleet, a key component of its military capabilities in the region.
The primary target of the drone strike appears to have been the Russian frigate Admiral Essen, a vessel capable of carrying Kalibr cruise missiles and reportedly used by Russian forces to launch attacks against Ukraine, as stated by Ukrainian Navy spokesperson Dmytro Pletenchuk in February. The attack on Novorossiysk comes as Ukraine continues to seek ways to disrupt Russia’s military logistics and demonstrate its resilience despite facing a larger and better-equipped adversary. The incident also raises questions about the effectiveness of Russian air defenses in protecting its naval infrastructure.
Damage to the Admiral Essen
OSINT analysts claim the attack caused damage to the midship structure of the Admiral Essen. The impact reportedly detonated PK-10 launchers, which are used for deploying passive jamming measures designed to disrupt enemy radar and guidance systems. Beyond the structural damage, several key electronic systems were also reportedly affected, including:
- The TK-25 electronic warfare system, responsible for detecting emissions and deploying active countermeasures.
- MR-90 Orekh radars, which guide surface-to-air missiles.
- Frigate-M2M surveillance radar, used for long-range detection of air and surface objects.
Molniya-Class Patrol Boat Also Hit
In addition to the frigate, a Molniya-class (Project 1241) missile boat was also reportedly struck by drones. The attack focused on the aft section of the vessel, damaging the main engines, diesel generators, and engine room – all critical components of the boat’s propulsion system. The aft section also houses two AK-630M 30mm gun mounts, used for close-in defense, and additional diesel generators that power the ship’s systems.
Earlier on March 4, sources within the Security Service of Ukraine (SBU) reported a drone strike on the port of Novorossiysk to RBC-Ukraine, though initial reports did not specify damage to the Admiral Essen.
Previous Attack on the Admiral Essen
This is not the first time the Admiral Essen has been targeted by Ukrainian forces. On April 2, 2022, while based in Sevastopol, the frigate was reportedly struck using a Neptune anti-ship missile, marking the first known apply of the domestically-produced weapon. The Steregushchiy-class corvette, of which the Admiral Essen is a part, has a standard displacement of 1,800 tons and a full displacement of 2,200 tons, according to Wikipedia.
The attack on Novorossiysk Bay comes amid increased Ukrainian efforts to target Russian military assets in the Black Sea and Crimea. The region remains a critical strategic area for both countries, with Russia using its naval presence to project power and control access to the Sea of Azov, while Ukraine seeks to disrupt Russian supply lines and regain control of its territory. The incident also follows a pattern of drone attacks targeting Russian infrastructure, demonstrating Ukraine’s evolving capabilities in asymmetric warfare.
The extent of the damage to both vessels remains unconfirmed, and Russian officials have not yet issued a comprehensive statement regarding the incident. Further assessments will be needed to determine the operational impact of the attack and whether the Admiral Essen and the Molniya-class patrol boat can be quickly repaired and returned to service. The situation remains fluid, and continued monitoring of the Black Sea region is crucial.
What comes next will likely involve further attempts by Ukraine to target Russian naval assets, as well as increased Russian efforts to bolster its defenses in the Black Sea. The incident underscores the ongoing risks to maritime security in the region and the potential for escalation. Share your thoughts on this developing story in the comments below.
