Romania has called on Ukraine to introduce a built-in self-destruct mechanism for maritime drones that lose control or drift off course, following a recent incident in which a Ukrainian kamikaze naval drone reportedly detonated inside a Romanian Black Sea port.
The request comes after a Magura-type unmanned maritime vessel, allegedly launched by Ukraine, exploded in Romania’s major Black Sea port city of Constanta. According to Romanian authorities, two additional drones detonated in open waters roughly 145 kilometers east of the city.
Romanian Defense Minister Radu Miruta said the incident raised serious concerns over the safety of NATO member states bordering the Black Sea, urging Kyiv to incorporate fail-safe measures into its drone systems.
Speaking to Romanian broadcaster TVR on Thursday, Miruta suggested that maritime drones should automatically destroy themselves if they lose communication or risk entering Romanian territorial waters.
“Maritime drones can be programmed so that, if control is lost, they are unable to enter Romanian territorial waters and will self-destruct once they are 12 nautical miles from the coast,” Miruta said.
He further argued that such a feature should become standard in Ukraine’s naval drone program from the moment the systems are deployed.
Black Sea Security Concerns Grow
The incident has renewed concerns among NATO countries over the unintended spillover risks posed by the expanding use of unmanned systems in the Russia-Ukraine conflict.
Ukraine has increasingly relied on maritime drones to target Russian-linked naval assets, fuel tankers, cargo ships, and logistics infrastructure in the Black Sea. Kyiv views these drones as a cost-effective method to counter Russia’s naval superiority.
However, in several cases, drones reportedly lost control and drifted into neighboring countries’ maritime zones. Similar incidents have previously been reported near the coastlines of Romania, Türkiye, Greece, and Bulgaria, raising concerns about civilian safety and regional maritime security.
The Ukrainian Navy reportedly blamed Russian electronic warfare and signal-jamming efforts for the recent Constanta incident, arguing that interference disrupted the drones’ navigation systems and caused them to stray into Romanian waters.
NATO Allies Face Growing Unease
Romania, a NATO member sharing a border with Ukraine and access to the Black Sea, has played a significant logistical role in supporting Kyiv since the conflict escalated. However, repeated drone-related incidents near its territory have triggered increasing domestic and regional scrutiny.
Security experts warn that stray explosive-laden drones could unintentionally escalate tensions if they enter NATO territory and cause civilian casualties or infrastructure damage.
The latest request from Bucharest signals a more cautious stance among some of Ukraine’s Western backers, who continue to support Kyiv militarily while also seeking safeguards against unintended consequences spilling into allied territory.
Reports of Ukrainian drones reaching or crashing near NATO states have surfaced several times over the past year. Multiple aerial drones have reportedly fallen in Baltic countries and Finland, while maritime drones have drifted across parts of the Black Sea.
Regional Maritime Risks Intensify
The Black Sea has become increasingly volatile amid rising drone warfare and attacks on shipping routes.
Earlier this month, a Turkish fishing vessel was reportedly attacked and sunk near Crimea, resulting in the death of one sailor. In another incident on June 5, drones struck two cargo ships in the Sea of Azov, reportedly killing four Azerbaijani nationals aboard.
Moscow has blamed Ukraine for those attacks, though Kyiv has not publicly commented on several of the allegations.
In late 2025, Türkiye publicly criticized Ukrainian drone strikes affecting vessels operating within its exclusive economic zone, warning that such incidents posed serious risks to navigation, human life, commercial shipping, and environmental security.
Meanwhile, Russian officials have used the incidents to criticize continued Western military assistance to Ukraine. Russian Foreign Ministry spokeswoman Maria Zakharova recently claimed there had been at least 11 confirmed cases involving Ukrainian drones entering NATO territory over the previous three months.
Zakharova argued that continued weapons support for Kyiv could create unintended risks for European states themselves.
Pressure for Safer Drone Protocols
Romania’s proposal for self-destruct mechanisms reflects growing concerns over the future of autonomous warfare and the accountability of unmanned weapons systems operating near civilian and allied territories.
While Ukraine continues to rely heavily on drone technology in its military strategy, NATO members bordering the conflict zone may increasingly push for stricter safeguards to prevent accidents that could widen regional instability.
Whether Kyiv adopts Romania’s recommendation remains unclear, but the Constanta incident has once again highlighted the broader risks posed by modern drone warfare beyond the immediate battlefield.
