According to Airbus, the operation included an Airbus H130 Flightlab helicopter, an ATR 72, a Cirrus SR20, and four drones prominently featuring the Airbus Aliaca UAS. On the ground, three firetrucks from the Departmental Fire and Rescue Service of Le Gard participated in the exercise.
During the trial’s operational flow, the Airbus Aliaca UAS flew high above a simulated ignition site, transmitting live infrared images directly to a mobile command unit on the ground. The Agnet platform secured the network connection and processed the data into actionable intelligence. Subsequently, the Airbus H130 Flightlab helicopter received optimized flight paths and exact drop coordinates directly on its cockpit display.
The trial successfully demonstrated highly accurate water drops executed just minutes after the simulated wildfire ignition.
“We connect aerial resources with ground assets using geolocation, observation data, and an integrated database accessible to all stakeholders. In this way, the firefighter commander no longer has to rely on fragmented radio calls,” stated Thierry Fol, Head of the Airbus Flightlab, in the company’s release.
Supporting Physical Assets
While the Wildfire Sentinel serves as the digital brain of the operation, Airbus continues to provide the physical muscle required for complex aerial firefighting. The digital system is designed to be fully interoperable with a global fleet of agile helicopters.
According to the provided specifications, this fleet includes the H125, a light, single-engine helicopter capable of carrying four firefighters and dropping 1,200 liters of water. The system also integrates with the versatile medium-sized H145, as well as the heavier H215 and H225 workhorse helicopters, which are specifically designed to operate in challenging weather conditions.
“Airbus’ ambition is to build an ecosystem that will answer the new challenges of managing wildfires in a more extreme environment,” noted Oliver Chalvet, Senior Manager for Firefighting Solutions at Airbus Defence and Space.

AeroDelft, a non-profit foundation run entirely by Delft University of Technology (TU Delft) students, has been developing “Project Phoenix” since 2018. According to supplementary research data, the initiative focuses on converting a Sling 4 airframe into a manned hydrogen-electric aircraft. Industry research highlights that in May 2025, AeroDelft became the first student team globally to test a full liquid hydrogen propulsion system in a lab setting, working alongside the Netherlands Organization for Applied Scientific Research (TNO).
Safety and Operational Planning
Operating an experimental aircraft at a commercial facility demands strict safety measures. According to project data, AeroDelft developed comprehensive risk analyses and an operational taxi test plan. This was achieved in close collaboration with research test pilots Alexander in ‘t Veld and Hans Mulder from TU Delft’s Flight Test Laboratory, ensuring that the live tests at RTHA’s Fieldlab Next Aviation facility met stringent aviation safety standards.
Technical Specifications and Infrastructure
Gaseous vs. Liquid Hydrogen
The recent taxi tests utilized gaseous hydrogen. While AeroDelft’s ultimate objective is to achieve flight using liquid hydrogen, gaseous hydrogen was selected for this phase due to its current technological maturity. Based on technical specifications provided in the research report, the single-seat converted aircraft uses a hydrogen fuel cell that combines hydrogen and oxygen to generate electricity, emitting only water. With a full tank of gaseous hydrogen, the aircraft is projected to have an endurance of approximately 40 minutes.
Transitioning to liquid hydrogen remains the next major technical hurdle. Because liquid hydrogen offers a significantly higher energy density by mass and volume, the team projects that utilizing liquid fuel will extend the aircraft’s flight endurance to approximately two hours. To achieve this, future development will require the integration of a cryogenic storage tank capable of maintaining temperatures at -253 °C, along with a complex distribution system.
The DutcHâ‚‚ Aviation Hub
The successful test campaign was facilitated by the DutcHâ‚‚ Aviation Hub, a collaborative ecosystem coordinated by the Rotterdam The Hague Innovation Airport (RHIA) Foundation and funded by the City of Rotterdam. The AeroDelft press release explicitly thanked partners including TU Delft Aerospace Engineering, RTHA, RHIA, and Air Products Benelux for their roles in turning months of preparation into a successful live test.
Perspectives on Sustainable Aviation
The transition to zero-emission aviation requires proving that new technologies are viable outside of controlled environments. Isha Moharir, Team Manager at AeroDelft, emphasized the importance of real-world testing in public remarks cited by industry reports:
“We want to demonstrate that flying on hydrogen works and that it’s safe in the air and at the airport… We are making absolutely no concessions on safety.”
Moharir further noted that testing at an operational commercial airport yields invaluable insights into the practical steps needed for sustainable aviation. Similarly, Daan van Dijk, an innovator at Rotterdam The Hague Airport, stated that these tests demonstrate tangible progress. According to research summaries, van Dijk highlighted that testing at an active airport is the exact method by which the aviation industry will learn to safely scale hydrogen-powered flight.
AirPro News analysis
We observe that while much of the aerospace sector’s attention has been focused on the in-flight capabilities of hydrogen aircraft, the logistical realities on the ground present an equally formidable challenge. The AeroDelft taxi tests at Rotterdam The Hague Airport serve as a crucial proof-of-concept for bridging the infrastructure gap. Traditional airports are optimized for kerosene; introducing hydrogen requires entirely new storage facilities, mobile refuelers, and emergency response protocols.
Furthermore, the broader hydrogen aviation race is accelerating. While battery-electric aviation propulsion shows promise for short-haul routes, the prohibitive weight of current battery technology limits its application for commercial passenger aviation. Liquid hydrogen presents a highly competitive alternative for longer ranges, provided that the cryogenic and logistical challenges, which initiatives like Project Phoenix are actively addressing, can be resolved at scale.
Frequently Asked Questions
What is Project Phoenix?
