A large-scale police operation is underway after a drone of unknown origin crashed 1 kilometer from a Bundeswehr base, German media outlet Bild reported on 15 September.

Drones have repeatedly flown over German military bases, and German prosecutors are already treating one August find near Ukraine-bound cargo as attempted sabotage. Germany's military counterintelligence has tied repeated sabotage on German soil to Russia, with high probability. Neither the owner nor the origin of this drone is known. Russia has denied involvement in earlier incidents, some of which Germany has officially attributed to it.

Discovery near airbase triggers large-scale search

Parts of the drone were found east of Lake Steinhude, the media outlet said. The crash site is one kilometer from the Bundeswehr's Wunstorf air base in Lower Saxony, the German military confirmed to the outlet. The drone crashed in an open, uninhabited area, the state criminal police office said. After the debris was discovered, authorities launched a large-scale search operation in the area to find additional parts of the UAV, according to Bild.

Investigators do not yet know who owns the drone

The search continues, and the state criminal police office says there are so far no indications of a danger to the public. Investigators learned about the discovery on Monday and want to analyze any other drone parts they find to determine its origin, the media outlet reported. Only then could more be said about the circumstances of the crash, it added.

Drones have been spotted over Bundeswehr bases many times

Since the beginning of the full-scale invasion, the number of reports of drone sightings has "increased significantly" and become "more consistent," a spokesperson for the Bundeswehr Operations Command told RedaktionsNetzwerk Deutschland (RND) in August.

"Overall, several hundred suspected drone overflights have been reported in the area of the German Armed Forces in recent years," the command spokesperson told RND.

What came before this crash

Germany is the busiest front in Russia's covert campaign in Europe. A Semtex-laden drone turned up beside a Ukrainian cargo plane at Leipzig/Halle airport in August, and investigators this month named a Russian intelligence operative and a Belarusian petty criminal. Berlin blamed Moscow and ordered Russia's Bonn consulate closed.

Two Bulgarians were arrested over a September arson at a Munich building site between two defense-tech headquarters, a day after two attempts to sabotage the power grid that Germany has not attributed. Germany suspects a planned assassination of a Bavarian drone maker's boss, watched by agents hired for single jobs.

Not every strand leads to Moscow. German military counterintelligence this week attributed part of the drone activity over Bundeswehr sites to Chinese intelligence.

Elsewhere the tempo holds: Polish prosecutors have opened more than a hundred espionage cases in 20 months, and in the Netherlands a former commander of US Army forces in Europe said Russian saboteurs attacked the rail network and tried to kill him, which Dutch Railways said they knew nothing about.
