Gadfin develops fast, hydrogen-powered drones with a quiet signature for long-range urgent deliveries and preventive maintenance missions. The patented technologies redefine delivery capabilities in terms of flight radius, safety, reliability, and automation. Among Gadfin's drones is Spirit-One, a long-range delivery drone for 3–6 kg (6–13 lb.) payloads that enables effective delivery of medical and other time-critical supplies at low cost. Gadfin's platform, engineered from the ground up by Israel's top aerospace industry experts, enjoys a sustainable advantage based on solid IP in aerodynamics solutions for drag decrease, a patented folding-wing mechanism, an integrated hydrogen fuel cell system that enables unmatched flight range, and advanced safety systems. The patented folding wings generate multiple advantages, such as withstanding strong side winds while vertically taking off and landing and requiring a small landing pad footprint. While the wings are spread, the drone achieves unparalleled energy efficiency, extended flight time, and range. Operated by unmanned autonomous robotic centers and tracked through cellular and satellite communication, the company's drones comply with international standards, including an emergency parachute and advanced anti-collision technology, enabling BVLOS flight in urban areas. Gadfin received the first permit from Israel's Civil Aviation Authority for urban airspace deliveries at the start of 2020, allowing hospitals, laboratories, and diverse organizations and institutions to be linked by drones. The flight network enables the fast and ongoing transfer of refrigerated medical cargo, such as samples, bone marrow, blood tests, blood donations, organs for transplant, and more, all within minutes and at very low cost.
