Finnish Firm Expands Capabilities In Intelligence Surveillance
Finnish deep tech firm Kelluu has closed a €15 million Series A funding round led by the NATO Innovation Fund, reflecting growing investor appetite for alternative intelligence, surveillance and reconnaissance (ISR) platforms. The company operates a fleet of autonomous hydrogen-powered airships that can remain airborne for over 12 hours and fly in temperatures as low as minus 33 degrees Celsius. Kelluu’s technology has been validated in harsh conditions, including along the Finland-Russia border, and the company has accumulated a track record of operational demonstrations with allied forces. The funding was announced on April 14, 2026, and reported by AeroTime.
