Key Takeaways:

JetZero has secured over $1 billion in funding and commitments, including a recent $175 million Series B round, with significant investment and partnerships from major players like United Airlines, RTX, Northrop Grumman, Delta, and Alaska Airlines.
The company is developing a blended-wing body (BWB) aircraft, the Z4, which promises up to a 50% reduction in fuel burn per passenger mile, significantly lowering costs and aiding airlines in achieving net-zero emission goals.
This funding will accelerate the development of a full-scale Z4 demonstrator, targeting a first flight in 2027 and eventual FAA certification for passenger, cargo, and military variants, while also offering an improved 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.
