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 ...

The X-76 is not intended for mass production or combat service. Instead, it will serve as a testbed for new aerial ...

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.

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

The X-76 is the latest in a long series of experimental X-planes developed by the Defense Advanced Research Projects Agency (DARPA).

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

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

The X-65 aircraft, which Aurora Flight Sciences is building for DARPA as part of the CRANE program, will use short air bursts to steer instead of traditional flaps and rudders. But rising costs, ...
