Kelluu develops and operates autonomous hydrogen-powered airships that provide persistent intelligence, surveillance, and reconnaissance (ISR) as well as civilian sensing applications. Its unmanned fleet supports missions exceeding 12 hours and multiple sensing modalities, enabling real-time, high-resolution imagery. The company says five airships operating from a single base can cover up to 30,000 square kilometres, and it operates what it describes as the world’s largest autonomous airship fleet. Kelluu was founded as a dual-use company and targets defence and civilian markets including forestry monitoring, meteorology, smart-city sensing, and protection of critical infrastructure. The firm is advancing Kelluu AI Labs to develop geospatial foundation models for environmental and resilience applications. Following a €15 million Series A, Kelluu plans to optimise its technology, scale operations, and expand fleet deployments.
