Sergey Brin backs 607-foot electric airship project in Ohio

Long-range ambitions, slower flight

Supercar Blondie reports that the 607-foot airship under development, codenamed Pathfinder 1, has a theoretical range of 10,000 miles and would not require a runway. Those figures describe its intended capabilities, not the results of the test flights reported so far.

Brin's company, LTA Research and Exploration, takes its name from "Lighter Than Air." It aims to make electric rigid-body airships cheaper and more efficient than conventional airliners. Supercar Blondie describes the vehicle as a luxury offering for now, with broader use dependent on the project's success.

Speed is not the main selling point. As LTA CEO Brett Crozier put it: "We're slower than a 777, but we're faster than most other things, and we don't need a runway."

Electric motors with hybrid power

Pathfinder 1 uses 12 Emrax 268 electric motors rated at 210 kW each and has a maximum speed of about 120 km/h (75 mph). Its electricity comes from a diesel-electric hybrid system with two diesel generators and 24 batteries, according to Wikipedia.

Helium provides lift rather than propulsion. IEEE Spectrum reports that the airship's rigid structure combines carbon fiber rods with titanium hubs, while 13 internal nylon gas cells hold non-flammable helium instead of hydrogen.

LTA says airships consume 60% less fuel than traditional passenger planes. That is the company's claim in support of its low-impact travel ambitions, rather than a reported result from Pathfinder 1's testing.

The flight-testing record

Pathfinder 1 received an FAA Special Airworthiness Certificate in September 2023, according to Wikipedia, which describes it as the first massive rigid airship of its kind to fly since the Graf Zeppelin II in August 1939.

Testing began with tethered flights at California's Moffett Federal Airfield in November 2023. The first untethered flight followed on October 24, 2024, after roughly a year of tethered testing.

On May 15, 2025, Pathfinder 1 ventured beyond Moffett Federal Airfield for the first time, flying two loops over San Francisco Bay. IEEE Spectrum called it the largest aircraft to fly in public since the 1930s.

The airship first crossed San Francisco's Golden Gate Bridge on October 28, 2025. According to the Royal Aeronautical Society, that three-and-a-half-hour trip was its furthest test flight to date.

Why airships face a difficult return

The project revisits a form of aviation displaced by disasters, operating constraints and advances in airplanes. Supercar Blondie points to the 1937 Hindenburg disaster as a defining example of the hazards of hydrogen-filled airships. Non-flammable helium offers an alternative, though the outlet says it is not globally viable.

Airships' vast surface areas also expose them to strong winds and turbulence. Docking demands substantial ground crews and specialized facilities. Meanwhile, fixed-wing aircraft reduced journey times and costs while improving safety: a transatlantic trip that took an airship days can take a jetliner hours.

Supercar Blondie argues that improvements in batteries and research into sustainable fuels could increase competition for Brin's project.

Akron's role and the next airship

The Akron Airdock once housed Goodyear's rigid airships for the U.S. Navy. The Akron Beacon Journal gives its dimensions as 1,175 feet long and 211 feet tall; Crozier said seven football games could be played inside at the same time.

LTA's ambitions extend beyond luxury travel. The company says its eventual airships are intended for humanitarian aid as well as passenger and cargo transport. At an Akron Roundtable event on November 20, 2025, Crozier also suggested an airship hospital, the Akron Beacon Journal reported.

IEEE Spectrum reports that LTA is developing a larger successor, Pathfinder 3, at a World War II-era hangar in Akron. Designed to carry more passengers or cargo, it will provide the basis for the airship the company eventually submits for FAA certification.
