Romania scrambled fighter aircraft and destroyed a marine drone dangerously close to the Neptun Deep natural gas development in the Black Sea, raising fresh concerns about threats to critical European energy infrastructure.

Romanian officials said the drone came from Russia, which has intensified military activity across the region during its war against Ukraine.

Romanian Defense Minister Radu Dinel Miruţă said the Coast Guard detected the vessel on Thursday morning a few hundred meters from gas extraction operations.

The location was about 80 miles east of Constanța, placing the unidentified craft inside an area central to Romania’s future offshore production ambitions.

After the detection, Romania’s defense ministry requested authorization from NATO to “take charge of the situation,” according to Miruţă.

Officials then evaluated the immediate risk to offshore workers, equipment, and installations associated with one of the most strategically important gas projects in the European Union.

“Following an assessment and in coordination with the President of Romania, the decision was made to destroy the drone in order to protect the lives of the hundreds of personnel working on the platform and to safeguard critical infrastructure,” Miruţă said.

Romania dispatched two F16 fighter jets with instructions to intercept the approaching drone.

“To ensure a rapid response, two Romanian F-16 fighter jets were scrambled with orders to engage. The drone was safely destroyed.”

Romanian President Nicușor Dan described the military response as “an action against time,” reflecting the urgency surrounding the encounter.

Dan said the drone had originated from Russia, although Moscow had not publicly responded to requests for comment about the Romanian accusations.

“I strongly condemn the intensification of these types of irresponsible incidents on the part of the Russian Federation,” Dan said. “We remain vigilant alongside NATO allies to defend ourselves and repel such challenges.”

Romanian investigators determined that only one drone was involved and said it was not Ukrainian.

That finding placed renewed attention on Russia as regional governments confront repeated aircraft and drone activity close to NATO territory, civilian communities, shipping routes, and essential energy assets.

NATO confirmed that two Romanian Air Force aircraft responded after a maritime drone was detected in Romania’s Exclusive Economic Zone.

“One of the aircraft successfully engaged the drone, demonstrating continued readiness to respond to any potential threat,” an alliance spokesperson said.

The location of the interception carries particular economic significance.

Neptun Deep lies roughly 99 miles offshore and is expected to begin producing natural gas in 2027, with the project positioned to transform Romania into the European Union’s largest gas producer.

That production is increasingly important for a region still adjusting to the energy upheaval caused by Russia’s full scale invasion of Ukraine in 2022.

European gas and electricity prices surged after Western governments imposed sanctions on Moscow and accelerated efforts to replace Russian oil and pipeline gas supplies.

Neptun Deep could strengthen regional supply security by bringing substantial domestic production into the European market.

It also gives Romania a larger strategic role in supporting neighboring states seeking diversified sources, while reducing exposure to Russian energy pressure and volatile international gas flows.

The latest incident follows a series of suspected Russian incursions affecting Romania. Romanian forces shot down another drone in late July after aircraft repeatedly entered or approached national airspace, prompting officials to warn that such activity could not be dismissed as an isolated navigation failure.

Dan said Romania and its allies were treating those episodes with “the utmost seriousness.”

He described the July airspace incursion as “inadmissible and intolerable,” language that reflected growing frustration in Bucharest over persistent military activity near the country’s borders.

The danger has also reached populated areas.

In May, a Russian drone struck an apartment building in Galați, a Romanian city near Ukraine, demonstrating how quickly operations linked to the conflict can place civilians and infrastructure inside NATO territory at risk.

Thursday’s interception adds a critical energy dimension to that security challenge.

With hundreds of workers near Neptun Deep and major production facilities under development, Romania is signaling that unidentified drones approaching offshore assets will face a rapid military response backed by coordination with NATO allies.
