French startup HyLight secures €13M Series A to expand its autonomous hydrogen airship fleet for infrastructure inspection.
French aerospace startup HyLight has secured €13 million in Series A funding to expand its fleet of autonomous, Hydrogen-powered airships designed for zero-emission critical infrastructure inspection. The investment will enable the Le Plessis-Pâté-based company to scale its operations from four to 15 active aircraft by 2027, targeting new markets across Europe.
The funding round, reported by Tech Funding News and EU-Startups on October 12, 2026, was backed by a consortium of investors including Rubio Impact Ventures, DRW, Teampact Ventures, Y Combinator, and Ring Capital. The capital injection aims to position HyLight’s 12-meter airships as a direct, decarbonized alternative to traditional Helicopters inspections for power lines, railways, and pipelines.
Scaling the HyLighter fleet
The company’s flagship aircraft, the HyLighter, is a 12-meter autonomous airship that utilizes helium for passive lift and a hydrogen fuel cell to power its electric motors. According to EU-Startups, the aircraft is designed to operate at a typical altitude of 25 meters, offering a target operational range of 350 kilometers and a maximum flight time of 10 hours per mission.
The airship features a 10-kilogram payload capacity dedicated to inspection equipment. This includes LiDAR sensors capable of capturing more than 1,000 points per square meter and high-resolution cameras delivering 1 millimeter per pixel resolution. The platform produces zero direct emissions and operates with minimal noise footprint compared to rotary-wing alternatives.
“Most power lines are still inspected by helicopter, just as they were fifty years ago. Our HyLighters already do the same job, with greater precision and less risk. This funding takes us from four aircraft to a fleet,” said Martin Bocken, co-founder and CEO of HyLight.
Regulatory approval and market demand
HyLight has already secured critical regulatory authorizations to conduct its missions. The French Civil Aviation Authority (DGAC) and the European Union Aviation Safety Agency (EASA) have authorized the HyLighter to fly beyond visual line of sight (BVLOS) over critical infrastructure in rural, suburban, and urban environments.
The company has accumulated more than 750 flight hours, inspecting thousands of kilometers of infrastructure across Europe. Current operational clients include major European infrastructure and utility operators such as Enedis, NaTran, Téréga, SNCF Réseau, and VINCI.
Helmer Schukken, managing partner at Rubio Impact Ventures, noted that traditional helicopter inspections remain expensive, polluting, and increasingly constrained by an aging workforce. He described HyLight’s platform as a clean, scalable alternative capable of operating reliably over densely populated areas while delivering significant cost savings for infrastructure operators.
The push for decarbonized infrastructure inspection
The demand for alternative aerial inspection platforms is driven by both environmental targets and the sheer scale of global infrastructure. According to EU-Startups, there are approximately 80 million kilometers of linear infrastructure worldwide requiring regular inspection. Traditional helicopters, which dominate this sector, emit up to 1 metric ton of CO2 equivalent per flight hour.
While operators have explored other technologies, existing alternatives present operational limitations. Battery-powered drones lack the endurance required for long-distance linear inspections, satellite imagery does not provide sufficient resolution for detailed component analysis, and ground-based sensors offer only localized data collection.
HyLight, founded in the early 2020s by Martin Bocken and Théo Hoenen, previously raised a €3.7 million seed round in April 2024. With the new Series A capital, the Y Combinator alumnus has raised approximately €16.7 million to date. The company plans to use the funds to expand its operational footprint into Germany and the Netherlands by 2027.
AirPro News analysis
We view HyLight’s successful Series A as a strong indicator of shifting priorities in the utility aviation market. Traditional helicopter operators face mounting pressure from both environmental regulations and rising operational costs. By securing EASA and DGAC approval for BVLOS flights over populated areas, HyLight has cleared the most significant regulatory hurdle that typically grounds autonomous aerial vehicles. If the company can successfully scale its manufacturing and field operations to 15 aircraft by 2027, it could establish a new standard for linear infrastructure inspection, potentially capturing market share from established rotary-wing operators in Europe before expanding globally.

The U.S. Coast Guard awarded a $247.8 million contract for four MQ-9B SeaGuardian UAS to expand its maritime surveillance fleet.
The U.S. Coast Guard placed a $247.8 million order with General Atomics Aeronautical Systems Inc. (GA-ASI) for four MQ-9B long-range unmanned aircraft systems to expand its dedicated maritime surveillance fleet. The procurement, finalized on September 25, 2026, and announced on October 9, 2026, includes ground control stations and supporting equipment.
According to the Coast Guard press release, the acquisition leverages an existing U.S. Customs and Border Protection (CBP) contract vehicle, accelerating the expansion of a shared Department of Homeland Security (DHS) unmanned aircraft enterprise based in San Angelo, Texas.
Expanding the shared homeland security fleet
The Coast Guard and CBP have a long-standing history of joint unmanned aircraft operations. The agencies began operating the MQ-9A Guardian Long-Range Unmanned Aircraft System (LR-UAS) through a joint program office in Texas following a pilot study initiated in 2008. This joint program was originally designed to provide long-endurance intelligence, surveillance, and reconnaissance (ISR) capabilities for ground agents on the U.S. Southwest border and was later expanded to provide maritime ISR in the Gulf of Mexico.
The Department of Homeland Security is actively scaling its MQ-9B enterprise to replace and augment these legacy platforms. In March 2026, CBP awarded a $265.5 million contract modification to General Atomics for additional MQ-9B aircraft, spares, and upgrades to support the shared DHS fleet based in San Angelo. The Coast Guard’s new $247.8 million order utilizes CBP’s existing procurement channels to expedite its own dedicated fleet expansion.
Funding for the Coast Guard’s acquisition stems from $266 million previously appropriated to the service’s LR-UAS program specifically to acquire four MQ-9B aircraft and associated equipment.
MQ-9B SeaGuardian maritime capabilities
The newly ordered MQ-9B is the next-generation evolution of the platform operated by the joint program office. The MQ-9B SeaGuardian variant is specifically missionized for maritime environments. The aircraft features a multi-mode maritime surface search radar equipped with an Inverse Synthetic Aperture Radar (ISAR) imaging mode, an Automatic Identification System (AIS) receiver, and high-definition full-motion video sensors.
Designed for extended operations, the aircraft can fly over the horizon via satellite communications for over 30 hours in all weather conditions. The MQ-9B is fully compliant with STANAG-4671, the NATO UAS airworthiness standard, which enables flexible operations in civil airspace alongside crewed aircraft.
Growing international market presence
The MQ-9B SeaGuardian is rapidly becoming a standard for international maritime security and coast guard agencies, highlighting its growing dominance in the medium-altitude long-endurance (MALE) UAS market. The Japan Coast Guard (JCG) selected the MQ-9B for its Remotely Piloted Aircraft Systems (RPAS) Project, beginning operations in October 2022 from the Japan Maritime Self-Defense Force (JMSDF) Hachinohe Air Base. The JCG utilizes the platform for wide-area maritime surveillance, search and rescue, disaster response, and maritime law enforcement.
Beyond maritime security agencies, the MQ-9B platform has been selected by several allied military forces. Current and future operators include the United Kingdom, Belgium, Canada, Denmark, Poland, Germany, Qatar, Taiwan, and India.
AirPro News analysis
The Coast Guard’s decision to piggyback on the CBP contract vehicle rather than initiating a standalone procurement highlights a strategic shift within the Department of Homeland Security toward unified, cross-agency aviation assets. By consolidating operations, training, and maintenance in San Angelo, Texas, the agencies reduce redundant infrastructure costs while rapidly scaling their medium-altitude long-endurance capabilities. We view this $247.8 million order as a critical step in standardizing maritime domain awareness tools across federal law enforcement, moving away from fragmented legacy platforms toward a standardized, interoperable MQ-9B enterprise.
