The largest aircraft in the world
Our proof-of-concept aircraft, Pathfinder 1, is a significant step toward redefining transportation and air travel to be more efficient, sustainable, and adaptable.
The Federal Aviation Administration (FAA) issued Pathfinder 1 its first Special Airworthiness Certificate in 2023, enabling flight testing at Moffett Field in Mountain View, California. Pathfinder 1 reached a significant flight testing milestone in May 2025, when it left the airfield and successfully completed maneuvers over the San Francisco Bay.
Flight testing: expanding horizons
Flight testing: expanding horizons
Pathfinder 1 is advancing its flight testing program in an expanded geographic region in the San Francisco Bay Area.
In this phase, the proof-of-concept airship will demonstrate its safety and reliability by flying farther, longer, and higher in different conditions.
By conducting incremental flight testing in varied conditions, we’re rigorously validating the design and performance of our prototype. Our systematic approach is aligned with aerospace standards, and the insights gained from flight tests will inform the continued development of the Pathfinder series in Akron, Ohio – the heart of lighter-than-air innovation in the United States.
Taking our mission to the skies
As we reach test milestones, we will steadily expand Pathfinder 1’s flight range – keep looking up and checking back here as we push forward.

Lighter-than-air capabilities
The future of airship technology makes possible the transport of people and cargo to destinations beyond the reach of roads, runways, and ports. Our vision is to develop the lighter-than-air technology that transforms air travel and rises to the world’s evolving needs.
