X-47B AV-2 in the air
The second X-47B demonstrator, known as Air Vehicle 2 (AV-2), reached an altitude of about 5,000 feet and flew several racetrack patterns, Northrop Grumman said. Before the end of the year, one of the two aircraft will be moved to Naval Air Station Patuxent River in Maryland for what the defense contractor calls "shore-based carrier suitability testing." The other will continue with "envelope expansion flight testing" at Edwards AFB.
