Key Takeaways:

JetZero, a developer of blended-wing body (BWB) aircraft, recently secured $175 million in Series B funding, bringing its total funding and commitments to over $1 billion.
Major partners and investors include United Airlines, RTX, Northrop Grumman, Delta Air Lines, and B Capital, with United holding a purchase agreement for up to 200 Z4 aircraft.
The Z4 aircraft is designed to reduce fuel burn by up to 50 percent per passenger mile, offer increased cabin space and comfort, and aims for a full-scale demonstrator flight in 2027.
This innovative aircraft is seen as a crucial tool for airlines to significantly lower operating costs and achieve their net-zero operational emissions targets by 2050.

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.
