The current H-1 fleet of AH-1Z Vipers and UH-1Y Venoms reached a major flight milestone by surpassing the 500,000-flight hour mark. Nearly 400 AH-1Z and UH-1Y helicopters, built by Bell Textron Inc. and operated by the U.S. Marine Corps and their allies, combined to achieve the milestone.

“The H-1 continues to be the premier example of a family of aircraft that can do more with less and deliver unmatched interoperability and expeditionary agility,” said Mike Deslatte, Bell H-1 vice president and program director. “We are thrilled to reach this tremendous milestone and excited for the future of both the Viper and the Venom as they continue to grow in number and capability around the world.”
