JetZero builds blended-wing jet to challenge Airbus and Boeing

JetZero is assembling a full-size demonstrator in a Mojave Desert hangar for a blended-wing aircraft that the company says could carry more than 200 passengers and cut fuel burn by as much as half. The California startup is pitching the jet as a direct challenge to Airbus and Boeing, but its path to commercial service still runs through certification, airport compatibility and airline economics.

The company’s Z4 is designed for 250 passengers and as much as 5,000 nautical miles of range, with the ability to run on conventional jet fuel and sustainable aviation fuel blends. United Airlines sees a path to order up to 100 aircraft, with an option for 100 more, if JetZero meets milestones that include a full-scale demonstrator flight expected in 2027. Alaska Airlines said it was the first airline to invest in JetZero through Alaska Star Ventures, tying its backing to its net-zero-by-2040 goal and to the prospect of lower operating costs, lower emissions and a quieter cabin.

The U.S. Air Force awarded JetZero a $235 million contract to fast-track the commercial demonstrator, and the Air Force says the same blended-wing-body architecture could have military airlift and tanker uses. Scaled Composites, the Northrop Grumman-owned aircraft developer, is building the aircraft, and JetZero is using Pratt & Whitney engines that also power the Boeing 757. JetZero says the middle-market jet would be about half the weight and require half the power of the Boeing 767-class aircraft it is intended to replace.

By merging the fuselage and wings into one lifting surface, JetZero wants to reduce drag and improve efficiency. The FAA granted the company an airworthiness certificate for its 12.5% scaled Pathfinder demonstrator in March 2024, but a full-size jet with a radically different shape still has to clear certification rules built around conventional tube-and-wing aircraft. JetZero revised the demonstrator design to use V-tails and winglets instead of wingtip rudders, ahead of a first-flight readiness assessment and a late-2027 target for first flight.

Blended-wing-body studies followed a NASA challenge in the early 1990s, later leading to Boeing and NASA X-48B and modified X-48C flight tests and wind-tunnel work. JetZero says founder and chief technology officer Mark Page led a three-year NASA initiative on blended-wing-body properties in the 1990s, and the company says NASA has spent more than $1 billion on the technology. JetZero was founded by Tom O’Leary and Page in 2020 or 2021 to focus on the concept.

JetZero broke ground on June 15, 2026, on an 8 million-square-foot factory on more than 600 acres in Greensboro, North Carolina, and says the site will create 14,500 jobs over 10 years. The plant is slated to build the Z4 using Siemens and Deloitte digital design tools.
