DLR announced it will invest more than 10 million euros to expand the Technology Center, a project expected to create up to 40 new jobs. The site builds upon existing infrastructure at Magdeburg-Cochstedt Airport, which DLR acquired in 2019 to establish a dedicated drone testing environment.
Following the official launch of the National Experimental Test Center for Unmanned Aircraft Systems in 2021, DLR resumed full operations at the airport in 2022. Since 2021, facility utilization has increased by approximately 20 percent annually. In 2025, the site recorded over 200 days of use, with external customers accounting for about half of the operational activity.
Federal Minister of the Interior Alexander Dobrindt emphasized the operational value of the location. He stated that researching and testing counter-drone technology directly at an active airport addresses environments where the threat situation is most sensitive.
Heightened Security Context Following Leipzig/Halle Incident
The opening of the Cochstedt facility aligns with an immediate operational need for counter-UAS defenses in Germany. During the first week of August 2026, security personnel discovered a quadcopter drone carrying semtex plastic explosives near a Ukrainian cargo aircraft at Leipzig/Halle Airport. The discovery prompted a major security alert and a temporary shutdown of the airfield.
German federal authorities are actively investigating the incident. While The Guardian reported that United States intelligence officials suspect Russian involvement in the attempted sabotage, the German government has not issued a formal accusation. The official cause and origin of the drone remain under investigation.
Dobrindt characterized the Leipzig/Halle event as a professional hybrid threat scenario representing a new level of danger for the country, underscoring the urgency of the research being conducted at the new DLR facility.
Federal and State Integration
The Technology Center represents a formal collaboration between the Federal Ministry of the Interior (BMI), the Federal Ministry of Research, Technology and Space (BMFTR), and the Federal Criminal Police Office (BKA). The joint initiative aims to streamline the transition of counter-UAS technologies from research and development into active deployment by security forces.
Anke Kaysser-Pyzalla, Chair of the DLR Executive Board, noted that the center serves as a logical continuation of the successful cooperation between federal and state police authorities. Dorothee Bär, Federal Minister of Research, Technology and Space, confirmed that her ministry already funds the existing UAS competence and test centers at the site, highlighting the joint financial and operational commitment between the research and interior ministries.
