On the morning of May 23, residents of Kombuli parish in eastern Latvia called police: something had fallen into a lake and exploded. Law enforcement discovered drone wreckage, rescue teams with a boat, a police drone, and National Armed Forces units were dispatched to the scene. There were no casualties.
The detail that transforms a local incident into a NATO problem: not a single sensor in Latvia's air defense system detected the object's appearance in the country's airspace. The device materialized only as wreckage on the lake bottom.
Not the First "Invisible" Drone
This is not a May anomaly — it is a pattern. During the previous incident in early May, when two Russian drones fell near an oil storage facility in eastern Latvia, the National Armed Forces command acknowledged a similar failure. According to Armed Forces representative Pudans, the drones entered airspace at different times, and sensors did not detect the first one either — despite the fact that Baltic air patrol fighters were already airborne and combat groups were on standby.

In other words: the system knew about the risk, but did not see the target.
Why Sensors Remain Silent
Kamikaze drones of the "Geran" type and their analogues have a small radar signature, fly at low altitudes, and are capable of deviating from course through electronic warfare — specifically from Russia's side. According to Latvia's Defense Ministry, it was precisely electronic warfare that could have deflected the drone from its route during a Ukrainian strike on targets on Russia's Baltic coast.
The Baltic region has become a de facto zone of "drone transit": since September 2025, dozens of unmanned aircraft have violated the airspace of Poland, Latvia, Estonia, and Lithuania. NATO leaders agreed to develop a concept of a "drone wall" on the eastern flank — but so far it remains a concept, not hardware.
What This Means for Civilians
Kombuli parish is a sparsely populated rural area. But the scenario of a "drone over a city" or a "drone over Ignalina Nuclear Power Plant" is mathematically not ruled out, as long as the detection system continues to malfunction. Latvia's command has already declared the need to review air defense operations at the border — without specific timelines or budgets.
If the next "invisible" drone falls not into a lake, but onto critical infrastructure — will Latvia have a case for emergency NATO funding of the sensor network that has been lacking so far?
