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

"The CH-47F Block II provides capability improvements allowing the US Army to lift more, fly farther and maintain their aircraft better than ever before," said Heather McBryan, vice president and program manager, Cargo Programs. "This modernization program enables the battle-tested Chinook to play a key role in multi-domain operations going forward."

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.

"As the Army's Heavy Lift platform of tomorrow, the CH-47F Block II provides increased capability while continuing support of the Army's requirement to remain strategically responsive across the full spectrum of operations," said Viva Kelly, US Army Cargo Helicopters acting project manager.

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.
