Boeing has achieved a significant milestone in the MH-139A Grey Wolf helicopter program by completing the Research, Development, Test & Evaluation (RDT&E) phase. The company delivered the sixth and final test aircraft to the U.S. Air Force in October 2023, allowing the Air Force to proceed with critical operational testing.
The MH-139A, set to replace the UH-1N Huey, will play a crucial role in protecting intercontinental ballistic missiles across the U.S. and in transporting VIP and security personnel.
