The Defense Advanced Research Projects Agency is channeling tens of millions of dollars into Aurora Flight Sciences for two experimental aircraft programs that together could redefine how the U.S.

DARPA has assigned the designation X-76 to the Speed and Runway Independent Technologies (SPRINT) project, a Bell proof-of-concept technology demonstrator for a high-speed tiltrotor. The DARPA ...

Bell just completed the Critical Design Review for DARPA's SPRINT program, meaning it can build its next-gen X-76 VTOL aircraft.

Planned to fly in 2028, the X-76 will explore technologies for fast-flying runway-independent aircraft with folding rotors, crewed and uncrewed.

DARPA’s X-76 experimental aircraft aims to combine helicopter flexibility with jet-like speeds and runway-independent flight.
