Aircraft program
Hybrid-Electric Demonstrator (HEX), a fully autonomous hybrid-electric vertical-take-off-and-landing (eVTOL) prototype. Maximum gross weight of 7,000 pounds.
The aircraft as engineered: what it is built from, the systems it flies with, and its configuration — each box a theme.
Technical reference compiled with AI research; a value appears only where two independent research passes and a web fact-check agree. Gaps are deliberate.
