This is reported by Süddeutsche Zeitung citing an internal Bundeswehr report.
According to the publication, between January 9 and 29, unidentified drones repeatedly entered the restricted airspace above the base.
Despite the use of electronic countermeasures against the drones, including the HP47 system, the Bundeswehr was unable to disable them or locate their operators.
The publication suggests that in Germany, it is believed that the drones were technologically advanced rather than standard commercial models. There are also suspicions that they may have been launched from ships in the North or Baltic Sea.
The German military has classified these incidents as potential espionage and reported them to intelligence agencies. The primary suspicion has fallen on Russian special services.
The airbase in the North Sea is considered a "special security zone." German soldiers are training there to master the Patriot air defense system. Additionally, Ukrainian military personnel have been training there for several months.
Weeks earlier, drones were spotted above the U.S. airbase in Ramstein—this facility is crucial for NATO's logistics. In response, the German government has developed a legislative amendment allowing the Bundeswehr to shoot down suspicious drones.
