Bell’s DARPA SPRINT demonstrator has received the X-76 designation after passing Critical Design Review, with flight testing planned for early 2028.

DARPA's X-76 aircraft, designed in cooperation with USSOCOM to break the trade-off between speed and agility, is set to move into the next production phase with Bell Textron.

Bell and DARPA announced the completion of the Critical Design Review (CDR) for the SPRINT aircraft, and its new name: X-76.

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

The Defense Advanced Research Projects Agency has advanced development of the X-76 experimental aircraft under its SPeed and Runway INdependent Technologies, or SPRINT, program. DARPA said Monday ...
