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 a Special Airworthiness Certificate in 2023, marking the beginning of LTA’s flight program from Moffett Federal Airfield in Mountain View, California. Pathfinder 1 reached a significant milestone in May 2025, when it left the airfield and successfully completed maneuvers over the San Francisco Bay.
Flight program: expanding horizons
Flight program: expanding horizons
Pathfinder 1 is advancing its flight program in the greater San Francisco Bay Area and other areas of California..
In this phase, the proof-of-concept airship will demonstrate its capabilities by flying farther, for longer periods, and in different conditions.
Our incremental and systematic flight program rigorously validates the design and performance of our prototype and is aligned with aerospace standards. The insights gained from these flights will inform the 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 new milestones, we will steadily expand Pathfinder 1’s flight range – keep looking up and checking back here as we push forward.
Brett CrozierEach fight brings us closer to a future where safety, reliability, and innovation in lighter-than-air technology redefine what’s possible.

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.
