In a major milestone for Boeing, the AH-64 Apache helicopter fleet has completed 3.5 million flight hours with the U.S Army since first being inducted in 1984. "Achieving and surpassing 3.5 million flight hours is a very significant milestone for the Apache, and I am incredibly proud of the soldiers who fly and maintain this helicopter," said Col. Jeff Hager, Apache project manager for the Army. "I am also pleased for the opportunity to work with dedicated and diligent men and women in government service and industry who design, build and continue to modernize an aircraft that delivers proven capabilities and cutting-edge technologies". The newest and most advanced Apache, the AH-64D Apache Block III, features composite main rotor blades, a composite stabilator, 701D engines with an enhanced digital electronic control unit, and an improved drive system that enhances the rotorcraft's performance. "The Boeing Apache team congratulates U.S. Army Aviation soldiers on achieving – and going beyond – the 3.5 million flight hour mark," said David Koopersmith, vice president of Boeing Attack Helicopter Programs. "Boeing is proud to provide its customers with helicopters that are relevant to their stated needs and ready to accomplish the mission".
