Constanta blast forces new drone protocol

On 5 June, a Ukrainian naval drone drifted into Constanta, Romania's biggest Black Sea port. It self-detonated between 10:27 and 10:28. Ukraine had notified Romanian authorities at 09:54, barely half an hour earlier, with the crisis already unfolding. Four Ukrainian drones had lost communications near Sevastopol, which Kyiv attributed to Russian electronic jamming, and entered an automatic self-destruct sequence. One reached a berth inside a civilian port in a NATO member state.

Romania's interim foreign minister Oana Toiu said on 5 July that Bucharest and Kyiv are negotiating a protocol: Ukraine would alert Romania when it loses control of drones and programme them to self-destruct before reaching Romanian territorial waters (HotNews). Turning that promise into an enforceable mechanism is another matter.

Who Decides Over Romania's Port

NATO runs air policing along its eastern flank and can track threats. It does not make engagement decisions over a member state's own port (NATO). Romania has sovereignty over its airspace and territorial waters. When a slow, cheap drone drifts toward a civilian berth, the call to evacuate workers or shut down a terminal falls to Romanian authorities, not to allied command structures.

That call depends on warning time. The numbers show how routine the threat has become. Since Russia's full-scale invasion began, Romania's defence ministry has counted more than 100 attacks near the border, 29 unlawful Russian drone entries into Romanian airspace, and 15 airspace violations in 2026 alone requiring 26 military-police scrambles (Agerpres). Romania has asked allies for low-altitude radars and interceptor drones to handle small, slow objects that conventional air defence was never built for (Straits Times), and has ordered 24 German Skyranger 35 counter-drone systems (ArmyRecognition). But procurement runs on years, not weeks. A bilateral protocol with Kyiv could close the gap faster, if one actually exists.

A Protocol Nobody Can Read

No signed text has been made public. DW Romania reported that after earlier drone incidents in Galați and Constanta, authorities promised explanations "in a matter of days." The public got unanswered questions instead.

A working protocol would need to resolve basics that nobody has publicly addressed. How many minutes does Ukraine have to notify Romania after losing contact with a drone? Where exactly must self-detonation trigger? Who receives the alert — the navy, the port authority, the border police? And if debris from a pre-border detonation still damages a ship or forces a port closure, who pays?

Lithuania offers a sharp contrast. On 30 June, its parliament passed a law giving civilians harmed when Lithuanian or allied forces lawfully shoot down a drone the right to claim compensation from defence funds, with a three-year filing window (LRT). Vilnius identified the liability gap, wrote legislation, and published it. Romania's protocol remains invisible to the port workers, shipping companies and coastal residents who would bear the cost of failure. The same improvisation plays out along NATO's entire eastern edge, with Latvia and Finland building separate counter-drone systems and liability rules with no shared template (Euronews, Yle).

Romania's interim defence minister Radu Miruta has said that responsibility lies with those who launch the drones — a line that separates solidarity with Ukraine from accepting routine spillover as normal. But a principle is not a claims procedure. Romania has described a safety plan more clearly than it has shown one. Until the protocol's terms are public, Constanta's port workers and shipping companies are left trusting a mechanism they cannot see.
