First test flight in 2027 The prototype aircraft, which is being built in a hangar in the Mojave Desert, is expected to perform its first test flight by the end of 2027. The program is financially backed by the US Air Force, while the construction of the demonstrator has been undertaken by Scaled Composites, a subsidiary of Northrop Grumman. The aircraft utilizes the same Pratt & Whitney engines that power the Boeing 757. If the first flight is crowned with success, JetZero aims to attract new capital in order to begin commercial aircraft production by 2030 at its new facilities in Greensboro, North Carolina. The timeline, however, largely depends on the certification process of the new design.
A design that NASA has been studying for decades
JetZero Chief Executive Tom O’Leary told Reuters that this is the first attempt to build a full-scale aircraft of this type. As he noted, the company is leveraging existing technologies and more than 30 years of research by NASA, which has been studying the blended-wing body concept for decades. Similar studies had been conducted in the past by Boeing, without, however, proceeding to the development of a commercial airliner. JetZero is keeping many of the prototype's technical details a secret. The primary goal is to prove that the new shape creates greater lift with less aerodynamic drag, thereby limiting the required thrust and, consequently, fuel consumption during flight. In the prototype, only the cockpit will be pressurized, while the space that will futurely accommodate passengers is currently being used for the installation of fuel tanks.
Targeting the market of 200 to 270 passengers
JetZero's Z4 model is intended for the mid-to-long-range aircraft category traditionally served by the Boeing 757 and Boeing 767, carrying approximately 200 to 270 passengers. The new design replaces the conventional cylindrical fuselage with a wide and flat cabin, allowing greater flexibility in seating configuration, larger windows, and a different layout for galleys and lavatories. At the same time, the engines are placed on the upper rear section of the aircraft, aiming to reduce ground noise and improve energy efficiency.
The major obstacles
Despite the enthusiasm surrounding the venture, industry experts point out that the company faces significant challenges ahead. The head of AeroDynamic Advisory, Richard Aboulafia, stated that the JetZero team has already positively surprised the industry, but must first prove the benefits of the design in practice and then secure the billions of dollars required for the certification and mass production of a new commercial aircraft. As he noted, the venture remains premature, but the possibility that we will see passengers traveling on JetZero aircraft in the future cannot be ruled out.
The US Air Force gave a boost to the program
JetZero was founded in 2020 and was initially met with considerable skepticism. The program gained significant momentum in August 2023, when the US Air Force selected the company to develop a demonstrator under a four-year funding program worth 235 million dollars. Aeronautical engineer and analyst at Leeham News, Bjorn Fehrm, estimates that the promised fuel consumption benefits have yet to be proven and believes that this specific design might be better suited for military transport or aerial refueling aircraft, where high capacity and low-observability characteristics are of greater importance.
Support from airlines and investors
Despite the technical challenges, market interest is growing. In January, JetZero raised 175 million dollars in a new funding round led by B Capital, with the participation of United Airlines Ventures, Northrop Grumman, and RTX Ventures. The investment by United Airlines includes the right to purchase up to 100 aircraft, as well as an option for another 100, provided the program is completed successfully. The company plans a new funding round by the end of the year, while also considering going public by 2028.
Eyes on the capital markets
According to Tom O’Leary, the highly positive investment climate for the aerospace industry, which was reinforced following the spectacular public listing of SpaceX, creates new fundraising opportunities. However, he admits that the company's future will be largely judged by the first test flight. As he characteristically mentioned, once the demonstrator flies successfully, airlines will gain the necessary confidence to start placing real orders, proving that the ambitious venture can evolve into a commercial reality.
