In support of ongoing US Army modernization efforts, Boeing delivered the first CH-47F Block II "Chinook" helicopter. The aircraft is one of up to 465 in the Army’s fleet that will be modernized to the new Block II configuration.

With an improved drivetrain, a reinforced airframe and enhanced fuel system, the CH-47F Block II provides for an additional 4,000 pounds of max gross weight and extends the mission radius for nearly all payloads. In addition to the capability improvements, the aircraft’s design enables future technology upgrades.

Additionally, the company’s Block II program improves aircraft sustainment. The improved reliability of the new rotor system minimizes unscheduled maintenance, and the simplified fuel system drives sustainment efficiency reducing maintenance burden and cost.
