World's Largest Electric Aircraft Completes First Flight
Heart Aerospace has flown the largest battery-electric aircraft to date, a milestone the Swedish-founded company says advances its plan to bring an electric passenger aircraft into commercial service.
The aircraft, named X1, has a 106-foot wingspan and weighs more than 25,000 pounds. It took off from a small airport in upstate New York, reached an altitude of 1,100 feet, and flew for 27 minutes before landing. According to Heart Aerospace, the flight used roughly $5 worth of electricity. The flight was conducted under a Special Airworthiness Certificate issued by the US Federal Aviation Administration, authorising crewed flight testing. The aircraft carried no passengers; it is a test vehicle built to demonstrate that electric propulsion works at this scale, not the finished commercial aircraft.
The aircraft it is designed to enable
The passenger aircraft in development, the ES-30, is intended to carry 30 passengers with a 25 kg luggage allowance each. Heart Aerospace says the aircraft will have a range of around 200 km on battery power alone, with a fast-charge time of 30 minutes between flights.
That range would bring routes such as Copenhagen–Aarhus or Copenhagen–Aalborg within reach on batteries alone, with no jet fuel burned and no CO₂ emitted in flight. Based on figures published by Heart Aerospace, the company estimates the electricity cost per passenger at around £2.50.
United Airlines, Air Canada and JSX have made a combined $9.4 billion in commitments toward the ES-30, and Heart Aerospace says it expects operating costs to run more than 40% below those of a comparable traditional regional aircraft. The company is targeting entry into commercial service in 2031.
Why the sector is under pressure to change
Aviation accounts for around 2.5% of global CO₂ emissions, according to industry estimates. Short regional flights make up a disproportionate share of that figure, since take-off and climb burn significantly more fuel per kilometre than cruising, meaning a short flight can carry a worse emissions profile per passenger than an equivalent distance on a long-haul route. These routes are also where small electric aircraft are considered most viable commercially: short enough to fly on batteries with current technology, and frequent enough that operating cost savings compound quickly.
What remains to be proven
The ES-30 itself has not yet flown. Heart Aerospace has said a further prototype and additional flight testing are required before the aircraft can be certified to carry paying passengers, with commercial service still targeted for 2031.
The completion of X1's first flight nonetheless represents a concrete technical step for an industry that has so far lacked a proven path to zero-emissions short-haul flight.
