Z4 all-wing jet with 5,000 nautical miles range secures $100M for 2027 first flight

JetZero has secured up to $100 million in new financing as it pushes development of its unconventional Z4 passenger aircraft. The capital will help advance the all-wing design toward full-scale flight testing and eventual production. The Z4 is designed to carry around 250 passengers across distances of up to 5,000 nautical miles. JetZero says its unusual configuration could reduce fuel consumption and emissions by as much as 50% compared with conventional aircraft carrying the same number of passengers. All-wing approach The Z4 replaces much of the traditional tube-and-wing layout with a broad airframe that combines the fuselage and lifting surfaces. JetZero believes that architecture can deliver aerodynamic and efficiency advantages over conventional passenger jets. The concept now needs to prove those benefits at full scale. A demonstrator called Jet1 is under construction and will provide engineers with their first opportunity to test the configuration in flight. JetZero reported that Jet1 was 40% complete as of June 2026. Scaled Composites, a Northrop Grumman company, is building the aircraft. Its first flight is scheduled for the fourth quarter of 2027. Testing should give engineers valuable data on the aircraft’s aerodynamic behavior, structures and onboard systems. 2027 flight test JetZero has already begun preparing for the next stage of the program. The startup broke ground on Factory1 in Greensboro, North Carolina, in June. The facility will support future Z4 production and testing as the company works toward an early-2030s entry into service. The company expects its North Carolina operations to create more than 14,000 jobs over the next decade. Moving an aircraft from a demonstrator into production requires substantial investment in tooling, equipment and facilities. JetZero’s new financing is intended to support that transition. CEO and co-founder Tom O’Leary said the facility is “targeted for pace.” He pointed to tooling and production facilities in North Carolina as key uses for the capital. New capital backs Z4 The senior secured term loan is led by Pinegrove Credit Partners and Silicon Valley Bank, a division of First Citizens Bank. Brookfield-backed Pinegrove and HRTG Partners also participated in the lender group. The company will use the financing for technology maturation, Demonstrator Jet1 manufacturing, and its U.S. facilities. The capital will also provide working capital for the company’s domestic operations. Sergey Kulyagin, JetZero’s CFO and treasurer, said the addition of credit providers gives the company another source of expertise as it develops its funding strategy. Pinegrove partner Craig Caukin described the financing as support for a critical transition in the program. “JetZero is moving from demonstration to production,” he said. Caukin added that the facility was structured around the program’s milestones. Pinegrove could expand the financing capacity as JetZero reaches new opportunities. The immediate test remains Jet1’s planned 2027 flight. That aircraft will put the Z4’s unusual airframe through its first full-scale flight test, bringing JetZero one step closer to finding out whether its efficiency targets can work beyond the drawing board.
