First PEGASUS SIGINT Aircraft Arrives in Germany for Integration
The first PEGASUS SIGINT Bombardier Global 6000 arrives in Germany for system integration with HENSOLDT and Lufthansa Technik, delivery by 2028.
This article is based on an official press release from Bombardier and additional program details from HENSOLDT and Lufthansa Technik.
First PEGASUS SIGINT Aircraft Touches Down in Germany for Final Integration
The first of three modified Bombardier Global 6000 aircraft destined for the German Bundeswehr’s PEGASUS program has successfully landed in Hamburg, Germany. According to an official statement from Bombardier Defense, the aircraft arrived at Lufthansa Technik’s headquarters on December 11, 2025, following a transatlantic flight from the manufacturer’s facility in Wichita, Kansas.
This arrival marks a critical transition in the multi-billion euro surveillance initiative. While the initial structural modifications were completed in the United States by Bombardier, the program now enters its systems integration phase on German soil. The project is led by general contractor HENSOLDT, which is supplying the “Kalætron Integral” signals intelligence (SIGINT) mission system, with Lufthansa Technik Defense responsible for the physical integration and eventual civil and military certification.
The PEGASUS (Persistent German Airborne Surveillance System) program aims to restore a sovereign airborne intelligence capability to the German Air Force, a capacity that has been largely absent since the retirement of the Breguet Atlantic fleet in 2010.
From Modification to Integration
The transfer of the aircraft from Kansas to Hamburg signifies the end of the airframe modification phase and the beginning of mission system installation. Bombardier Defense performed the foundational structural work required to accommodate the complex sensor suite, including the addition of significant external fairings and internal provisions.
Now in Hamburg, Lufthansa Technik will install the intelligence-gathering hardware. In a press statement regarding the milestone, Michael von Puttkamer, Vice President of Special Aircraft Services at Lufthansa Technik, highlighted the complexity of the next steps:
“This milestone marks the start of an exciting new phase in which we will bring together technology, craftsmanship, and special mission aircraft expertise.”
Once integration is complete, the aircraft will undergo rigorous testing to ensure it meets both civil aviation standards and military requirements before delivery to the German Air Force.
Technical Capabilities: The Kalætron Integral System
At the core of the PEGASUS platform is HENSOLDT’s “Kalætron Integral” suite. According to technical data released by HENSOLDT, this system combines communications intelligence (COMINT) and electronic intelligence (ELINT) into a fully digital architecture.
Surveillance Specs
The system is designed to operate across an extremely broad frequency range. Program specifications indicate the sensors can detect emitters ranging from 20 MHz to 40 GHz. This capability allows the crew to monitor radio communications as well as detect and analyze radar signals from potential adversaries, such as air defense systems.
Jürgen Halder, Vice President of Airborne SIGINT at HENSOLDT, emphasized the importance of the aircraft’s arrival for the engineering teams:
“With the arrival of the first aircraft in Hamburg, we are entering the crucial phase of system integration and qualification… bringing the next generation of airborne intelligence to life.”
The system utilizes artificial intelligence and machine learning to automate the classification of signals, generating a real-time “Electronic Order of Battle” (EOB) that identifies the location and type of enemy forces. This data can be shared with NATO command structures, providing a high-altitude, independent intelligence contribution from Germany.
AirPro News Analysis: Closing the Capability Gap
The arrival of the first PEGASUS aircraft represents a significant recovery for German military procurement. For over a decade, the Bundeswehr has relied on allied assets for airborne SIGINT following the retirement of the BR1150 Breguet Atlantic. The previous attempt to fill this gap, the Euro Hawk drone project, was cancelled in 2013 due to spiraling costs and certification challenges regarding flight over populated European airspace.
By shifting the platform to a manned Bombardier Global 6000 business jet, the program leverages a proven, certified airframe. The Global 6000 offers a service ceiling of up to 51,000 feet and a range of approximately 6,000 nautical miles, allowing for extended “on-station” time similar to the cancelled drone program, but with a smoother path to certification in civilian airspace. This pragmatic approach suggests a shift in German defense strategy toward modifying commercial-off-the-shelf (COTS) platforms rather than developing entirely new airframes.
Future Timeline and Operations
Following the integration work in Hamburg, the aircraft will undergo flight testing and certification. The current program timeline projects the delivery of all three aircraft to the German Air Force between 2026 and 2028.
Once operational, the fleet will be stationed at Schleswig-Jagel Air Base and operated by Tactical Air Force Wing 51 “Immelmann.” This unit, which currently operates Tornado jets and IAI Heron drones, will utilize the PEGASUS fleet to conduct strategic reconnaissance missions on the periphery of crisis zones.
