In a stunning escalation in the Black Sea, a senior official from Ukraine’s Security Service (SBU) has confirmed that Ukrainian naval forces carried out the drone strikes that crippled two Russian-sanctioned tankers near Turkey’s coastline. The admission marks one of Kyiv’s boldest operations to date against Moscow’s so-called “shadow fleet,” a network of aging, lightly regulated tankers used to covertly transport Russian oil in defiance of Western sanctions.
Twin Explosions Hit Shadow Fleet Tankers
The tankers — Virat and Kairos — were rocked by explosions Friday afternoon and evening, according to Turkey’s Ministry of Transport. Both vessels, registered under the flag of Gambia and long monitored by Western agencies, are on the sanctions list for ferrying crude oil from Russian ports in violation of post-2022 embargoes.
On Saturday morning, a third explosion struck the Virat. Turkish officials attributed that blast directly to an unmanned maritime drone, escalating concerns that the Black Sea is becoming a hot zone for high-tech naval warfare.
Despite the intensity of the attacks, none of the crew members on either vessel were injured. All 25 crew members of the Kairos were safely evacuated after fire engulfed portions of the ship, while all 20 crew members aboard the Virat were unharmed, Turkish authorities confirmed.
SBU: This Was a Coordinated Sea Baby Drone Operation
Speaking anonymously to Reuters and AFP, the SBU official said the strikes were carried out using Sea Baby naval drones, a domestically developed unmanned system that has become central to Ukraine’s asymmetric maritime strategy.
He stated that both tankers suffered “critical damage” and were “effectively removed from operation,” describing the attack as a significant blow to Russia’s ability to circumvent oil sanctions.
“This operation was conducted by Ukrainian counterintelligence and naval forces,” the official said.
“Video footage shows both tankers received catastrophic damage.”
The official did not specify the exact timing of the attack, but Western maritime monitors reported sudden course deviations and emergency alerts from both vessels.
Turkey Confirms Drone Strike; Cause Initially Unclear
Turkey initially said the cause of the explosions was uncertain, citing possibilities ranging from naval mines to missile impact. But by Saturday morning, the Turkish Ministry of Transport confirmed that at least one of the explosions — the second blast aboard the Virat — was caused by a maritime drone.
The Kairos, which was en route from Egypt to the Russian port of Novorossiysk, also reported a rapidly spreading onboard fire following its explosion.
Strategic Pressure on Moscow’s Oil Lifeline
The attacks highlight a growing vulnerability in Russia’s shadow fleet, a collection of often poorly maintained tankers operating with minimal transparency. Western governments have long warned that these vessels pose environmental and security risks due to their lack of proper safety standards and opaque ownership structures.
Ukraine’s targeting of these ships represents a dramatic attempt to disrupt Russia’s revenue streams — especially oil transported outside official channels to avoid sanctions.
Analysts say the strikes could complicate Moscow’s ability to maintain steady exports, particularly if insurance providers and maritime operators view the Black Sea as increasingly unsafe.
No Civilian Casualties, But High Political Stakes
While there were no crew casualties, the political fallout is significant. Russia has not yet publicly responded to the SBU’s claim, but Moscow has repeatedly accused Ukraine of attempting to militarize international waters.
Turkey, meanwhile, remains on high alert. The country has faced repeated incidents involving mines and unidentified drones since the 2022 invasion and is attempting to balance its NATO commitments with its fragile diplomatic relationship with Moscow.
Conclusion
If confirmed, Ukraine’s operation marks one of the most aggressive maritime strikes of the war, directly targeting vessels tied to Russia’s sanctioned oil infrastructure. As naval drones increasingly reshape the conflict, the Black Sea is rapidly emerging as one of the most volatile flashpoints of the Russia-Ukraine war — with global consequences for energy security, maritime law, and regional stability.
