NIKOLAEV — Russian drone strikes hit two cargo ships at Nikolaev port on Sunday, targeting vessels that were delivering supplies to Ukrainian armed forces, Russia’s military said. A third vessel — a tugboat that had been converted for deployment as an uncrewed surface drone — was also struck in the same operation, according to the Russian Defense Ministry’s announcement.
The port at Nikolaev, known in Ukrainian as Mykolaiv, sits near the mouth of the Southern Bug River and has served throughout the Russian operation in Ukraine as one of the primary entry points for military cargo reaching the southern front. Its proximity to Kherson — the regional capital that remains contested along its eastern bank — has made it a consistent target for Russian strikes throughout the conflict. Sunday’s announcement is among the more detailed that the Russian military has issued about a single port operation in recent months.
The description of the third vessel as a converted tugboat is the element of Sunday’s statement that carries the most tactical significance. Ukraine has developed and deployed uncrewed surface vessels — maritime drones — with increasing sophistication over the past two years. Those drones have been used to strike Russian naval assets in the Black Sea, including attacks on vessels in Sevastopol harbor, and their effectiveness has been significant enough that Russia’s Black Sea Fleet relocated much of its operational presence away from Sevastopol. A tugboat modified to carry or deploy such drones represents a category of asset that the Russian military has prioritized for destruction.
The Defense Ministry statement did not specify how many drones were used in Sunday’s operation, the type of munitions employed, or the extent of damage to any of the three vessels. It did not confirm whether any of the ships were sunk or whether the strikes left the vessels disabled in place. Port operations at Nikolaev and the status of the targeted ships could not be independently confirmed as of Sunday evening.
Ukraine’s military has not commented on Sunday’s Russian statement. That silence is consistent with Kyiv’s general practice of not confirming strikes on logistical infrastructure until it has completed its own damage assessment, if at all. Ukrainian officials have in past cases acknowledged strikes on military-linked cargo at southern ports while declining to confirm specific details about the vessels involved.
The distinction the Russian military drew between the two cargo ships and the converted tugboat matters legally and operationally. Under the laws of armed conflict, a military vessel — even a converted civilian one — carries a different targeting status than a civilian cargo ship, even one carrying military supplies. Whether the cargo ships involved in Sunday’s strike were civilian-flagged vessels is not specified in the Russian statement, and that question will likely surface in maritime legal discussions about the incident.
Nikolaev has absorbed strikes across multiple domains throughout the Russian operation in Ukraine. Missile strikes on the city itself have damaged infrastructure including grain terminals and residential areas. Drone strikes on port facilities have targeted fuel storage and loading equipment. Sunday’s announcement is notable for its focus on the ships themselves rather than the fixed port infrastructure — suggesting a shift toward interdicting the supply chain at the moment of cargo transfer rather than destroying the terminal capacity.
Neither the identity of the ship operators nor the flag states of the vessels were disclosed in the Russian Defense Ministry statement. Those details, if they emerge from maritime tracking databases or from the companies involved, will clarify the legal and diplomatic dimensions of Sunday’s strikes. In their absence, what is confirmed is that Russia conducted drone strikes on Nikolaev port on Sunday, targeted at least three vessels, and described two of them as actively involved in delivering supplies to Ukrainian armed forces.
