Overview

The US military has successfully conducted a flight test of the XRQ-73, an experimental hybrid-electric stealth drone designed by Northrop Grumman. This drone features a next-generation propulsion system aimed at achieving longer and quieter flights, marking a significant step in military drone technology.

The flight took place at Edwards Air Force Base in California in April, as announced by the Defense Advanced Research Projects Agency (DARPA). The XRQ-73's design is reminiscent of established stealth aircraft, including the B-2 Spirit and the RQ-170 Sentinel.
