Customer Profile

The Boeing Company is a world leader in the design and manufacturing of military fixed wing and rotorcraft aircraft. Their CH-47F modernization program will sustain the U.S. Army’s Chinook fleet to provide rotary-wing, heavy-lift capabilities well into the 21st century. Modernization includes:

  • Aircraft remanufacturing
  • Vibration and noise reduction

Among its products are the AH-64D Apache Longbow attack helicopter, CH-47 Chinook and the V-22 Osprey tiltrotor aircraft.
