ES-36

Introducing the ES-36.

A clean-sheet, hybrid-electric regional aircraft designed to reset the economics of short-haul flying.

A JSX Heart ES-36 climbs.

New economics for regional aviation.

Hybrid-electric propulsion, simplified systems, and modern software fundamentally lower aircraft operating costs.

  • Cost

    More than 40% lower aircraft operating costs at entry into service, with further improvements as technology advances.

  • Climate

    Zero operational CO₂ emissions on all-electric routes and substantially lower emissions in hybrid operation.

  • Crew

    A safer, fly-by-wire flight deck reduces pilot workload.

  • Fees

    Lower-emission operations reduce exposure to rising carbon taxes and emissions-related aviation charges across global markets.

  • Maintenance

    Electric propulsion, simplified aircraft systems, and reliable software slash maintenance costs and aircraft downtime.

  • Energy

    Domestic grid electricity replaces jet fuel with a lower-cost, more price-stable source of energy for airlines.

Right-sized range for regional networks.

125 miles of all-electric flight and 745 miles of hybrid range designed for the world's most popular short‑haul corridors.

  • Americas

    The world’s largest domestic aviation market, with 5,000 airports and a network dominated by sub-500-mile routes.
