AALTO HAPS

What AALTO HAPS does

AALTO HAPS is a majority-owned subsidiary of Airbus Defence and Space, headquartered in Farnborough, United Kingdom, that designs, manufactures, and operates the Zephyr, a solar-powered High Altitude Platform Station (HAPS). The Zephyr is a fixed-wing, unmanned, ultralight aircraft designed to operate persistently in the stratosphere, where it functions as a quasi-stationary platform for mobile broadband backhaul, direct-to-network 4G/5G connectivity, and Earth observation. The company holds a world record of 67 days of continuous stratospheric flight, holds UK Civil Aviation Authority Design Organisation Approval (the first granted to any HAPS operator), and operates AALTOPORT, a launch and recovery base in Kenya, alongside its UK operations.

The company's commercial model is anchored on service-based revenue from mobile network operators (MNOs) seeking coverage extension into underserved geographies, with additional revenue potential from government and defense surveillance and Earth observation. Named customers and partners include NTT DOCOMO, Space Compass, Telkomsel, Paradise Mobile, and Mitratel, and a framework agreement with Telkomsel was announced in 2026 ahead of targeted commercial entry-into-service in 2026. Leadership appointed Hughes Boulnois as CEO in October 2024 to commercialize the platform, and the company raised approximately $100 million from a Japanese consortium in June 2024 to fund certification, manufacturing scale, and operational expansion. The company employs 190+ people and remains in a pre-commercial scale-up phase, with revenue not publicly disclosed.
