Key Takeaways:

JetZero has raised $175 million in Series B funding, bringing its total funding and commitments to over $1 billion for the development of its blended-wing body (BWB) aircraft.
Major aviation players, including United Airlines, RTX, and Northrop Grumman, are investing in JetZero's Z4 BWB design, which aims to reduce fuel burn by as much as 50 percent per passenger mile.
The new funding will accelerate the development of a full-scale demonstrator, with the company targeting a first flight in 2027 for an aircraft designed to fit existing airport infrastructure and offer increased cabin space.

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.
