A heavily modified Airbus A320 has been declared an operational flying laboratory for the ECRS Mk1 radar programme, following the completion of commissioning flights at Manching in Bavaria. Airbus and its industrial partners announced the milestone on 6 November, marking the transition from ground testing to active airborne development work.
Registered D-ATRA and carrying the official designation Advanced Technology Research Aircraft (ATRA), the jet is owned by the German Aerospace Center (DLR). Its principal function is to advance the development of the Eurofighter Common Radar System Mk1, an AESA radar that Hensoldt and Indra have jointly developed for the nations that operate the Eurofighter.
What the Aircraft Became
Extensive structural modifications were needed to prepare the aircraft for its new role. A Eurofighter-style nose section was grafted on after Airbus strengthened the airframe, with data cabling running throughout the fuselage to the tune of hundreds of metres. Both liquid and air cooling systems were added to keep the radar within its required operating temperature range. The cabin interior was reconfigured to house engineer workstations from which radar performance and data can be monitored in real time during flight.
The modified nose made its first flight in January 2025, though the aircraft took to the air at that stage without an active radar installed. Once those airworthiness flights were complete, ground testing was conducted before the commissioning programme got under way.
Five Flights, One Clear Result
The commissioning programme consisted of five flights conducted between 7 October and 5 November 2025, as reported by Simple Flying, with every sortie operating out of Ingolstadt-Manching Airport (IGS) in Bavaria. The opening flight on 7 October ran for three hours and 46 minutes, according to Simple Flying.
Across the five sorties, crews were able to confirm that the ECRS Mk1 radar and the aircraft functioned successfully together whilst airborne. That validation in genuine operating conditions is precisely what a flying laboratory exists to achieve, delivering what no ground rig can fully replicate.
Erik Lorch, Head of the E-Scan Mk1 Programme, offered a straightforward assessment of what the system brings: "This radar greatly enhances the capabilities of the Eurofighter in both air-to-air and air-to-ground operations."
Who the ECRS Mk1 Radar Is Built For
On the customer side, the ECRS Mk1 is set to equip aircraft procured through Germany's Quadriga and Tranche 5 programmes and Spain's Halcón programme. Both nations consequently have a direct interest in the results D-ATRA generates: every hour spent aloft yields data that will influence the production standard ultimately delivered to their air forces.
According to a June 2026 update cited by Aerospace Global News, the industrial partners have set 2027 as their target year for delivering ECRS Mk1 to Germany and Spain. The flying laboratory effort is therefore proceeding alongside what is now a comparatively near-term production and delivery timeline.
The United Kingdom is pursuing a separate path. Aerospace Global News also reported that the RAF is working towards the Leonardo-developed ECRS Mk2, an upgrade intended for 40 Tranche 3 Typhoons, with entry into service expected before the end of the decade.
A Busy Period for Airbus Research Flying
D-ATRA is not the only Airbus airframe generating headlines for research work. We recently covered the Airbus U740 Valkyrie completing its first flight in Europe with a 2029 target set, and the Airbus A350F completing its first flight in September 2026. The ATRA commissioning milestone sits within a broader period of active flight-test activity across the manufacturer's programmes.

The Bottom Line
D-ATRA is now a functioning airborne testbed for one of the more consequential radar upgrades in current European combat aviation. Five flights and a programme declaration of operational status are, in themselves, a modest milestone. What they enable is not: the laboratory will now begin the sustained development flying that the Eurofighter communities in Germany and Spain are depending on ahead of a 2027 delivery target. The commissioning announcement confirms the programme is moving, and moving on schedule.
