We were honored to fly the Acceptance Test Procedures for all eight MQ-9A Block 5 aircraft delivered to the Royal Netherlands Air Force, including the final aircraft in the program.

Conducted from Gray Butte Flight Operations Facility in California, this milestone reflects the professionalism and coordination of all the teams supporting the U.S. Air Force and its foreign partners in critical developmental test and evaluation.
