Key Takeaways:

JetZero secured $175 million in Series B funding from investors including United Airlines, RTX, and Northrop Grumman, bringing its total funding and commitments to over $1 billion for its blended-wing body (BWB) aircraft.
The BWB design promises to cut fuel burn by up to 50 percent per passenger mile, significantly reducing costs for airlines and aiding their net-zero operational emissions targets.
JetZero is accelerating the development of a full-scale Z4 demonstrator, with the first flight targeted for 2027, and has a conditional purchase agreement with United Airlines for up to 200 aircraft.
Beyond fuel efficiency, the Z4 aircraft is designed for up to 250 passengers, will fit existing airport infrastructure, and offers a more spacious and comfortable cabin experience.

United Airlines, RTX, and Northrop Grumman are all betting on a clean-sheet aircraft that promises to reduce fuel burn by as much as 50 percent per passenger mile, compared to similarly sized tube-and-wing models.

California-based JetZero—which has ditched the conventional tube-and-wing for a blended-wing body (BWB) or “all-wing” configuration—said Tuesday that it raised $175 million in a Series B round led by B Capital, a new investor.
