Most Black Sea Drones Were Seen by Sailors, Not Radar. Early Warning Is Now the Operator's Job

Quick answer: a Romanian TV investigation published on 28 September 2026 reports more than 31 drones and sea mines in eight months in Romania's Black Sea area, and says most drones were spotted by sailors, not by military radar. Two senior officials said platform and port operators must install their own early-warning sensors. The practical question for an operator is no longer only which sensor to buy, but how to bring the weak signals it already has into one picture, including what people on the water see.

What the investigation found

The figures below come from an investigation by the PRO TV programme "România, te iubesc!", reported by Libertatea on 28 September 2026. They are the reported figures, not our measurements.

• ✓Romania has to watch roughly 30,000 square kilometres of the Black Sea, out to about 160 kilometres from the coast.
• ✓More than 31 drones and sea mines were reported in the first eight months of the year in the area under Romanian responsibility.
• ✓Twelve drones were reported around the Neptun Deep gas field alone, about 160 kilometres offshore, where a navy or coast guard ship needs more than four hours to arrive.
• ✓On 20 August a drone came within 500 metres of the Neptun Alpha platform. F-16 fighters were sent; a pilot fired on it with the onboard cannon, and military divers later neutralised it.
• ✓On 5 June 2026 a sea drone entered the port of Constanța without being detected, travelled about five kilometres between the breakwaters and exploded near a maritime rescue agency.
• ✓Coast guard ships spent about 9,800 hours at sea in 2022 and about 6,200 in 2025, a fall of almost 40 percent.

And the sentence that matters most: many of the drones were seen by sailors on ships in the area, not by the army's radar systems.

Early warning is moving to the operator

Two statements in the investigation change who is expected to buy detection. In our translation from Romanian:

• ✓The acting defence minister, Radu Miruță, said operators must install sensors able to signal a danger as early as possible.
• ✓The head of the Romanian Navy, Vice-admiral Mihai Panait, said the platform operators must install surveillance cameras and protection against mines and drones, because the army and the police cannot keep ships everywhere at all times.

Whatever one thinks of that division of responsibility, the direction is clear. Early warning at an offshore platform or a port is becoming the site owner's problem as well as the state's.

Why "seen by sailors" is the important line

If people on the water see a threat first, their observation is a sensor. It is often the best one available: a person recognises an object that a navigation radar filters out as sea clutter.

A human report is only worth something, though, if it arrives quickly and in a usable form: a position, a time, a direction of travel, ideally a photo, and in the same place where the site already sees its radar tracks, its cameras and the vessels that announce themselves.

At sea, those vessels announce themselves through AIS, the ship identification system carried by larger ships, the maritime counterpart of the air-traffic data aircraft broadcast. A contact that a radar or a camera sees, but that sends no AIS report, is exactly the contact worth a second look.

What fusion adds, and what it does not

Fusion means correlating independent weak signals and raising an alert when they agree, with an explanation a person can check. For a platform or a port, the signals would be:

• ✓the site's own navigation radar tracks;
• ✓day and thermal cameras;
• ✓AIS reports from nearby traffic, to separate declared vessels from unknown ones;
• ✓reports from crews and staff, with position and time.

What fusion does not do: it does not make a small, low, fast surface drone visible to a sensor that cannot see it. Range and sensitivity come from the sensors. The gain is in agreement, speed and fewer false alarms, and each of those has to be measured at a real site before anyone claims it.

Where DroneWatch AI stands

This is the idea behind DroneWatch AI, a software layer I am building for early warning against aerial drones. It correlates independent sources and treats human reports as a source in their own right. Its limits belong in the same paragraph: the drone-threat signals are simulated, it is not operational, it has never detected a hostile drone, and it has no maritime sensing today. A maritime version, with AIS as the cooperative feed and crew reports as the human input, is a design direction for a pilot with a host site and a sensor partner, not a product.

Early warning here is defensive only: the system informs, and a person decides.

The question worth asking

For anyone who operates at sea or in a port: when one of your people sees something suspicious on the water, by what route does the report reach the person who decides, and how long does it take?

Frequently Asked Questions

How many drones were reported in Romania's Black Sea area in 2026?

According to a PRO TV investigation reported by Libertatea on 28 September 2026, more than 31 drones and sea mines were reported in the first eight months of 2026 in the area under Romanian responsibility, including 12 drones around the Neptun Deep gas field.

Who is expected to detect drones at offshore platforms and ports in Romania?

In that investigation, both the acting defence minister and the head of the Romanian Navy said operators should install their own sensors and protection, because the navy and coast guard cannot keep ships everywhere. Responsibility is described as shared between the navy, the coast guard and the operators.

Can reports from people be used as a sensor?

Yes, if they arrive quickly and in a structured form: position, time, direction and ideally a photo, in the same picture as radar, cameras and AIS. The investigation says many drones were first seen by sailors, which makes human reports one of the most valuable inputs.

Does DroneWatch AI detect maritime drones?

No. DroneWatch AI is a concept demonstrator for aerial drones, with simulated threat signals, and it is not operational. A maritime version is a design direction that would need a host site, a sensor partner and field measurement before any capability could be claimed.
