written by Newsdesk | July 5, 2024

Boeing has delivered the first CH-47F Block II Chinook helicopter to the U.S. Army, marking a significant milestone in the military’s modernization efforts.

The upgraded aircraft is the first of up to 465 Chinooks in the Army’s fleet that will be modernized to the new Block II configuration.

Heather McBryan, vice president and program manager of Cargo Programs at Boeing, said: “The CH-47F Block II provides capability improvements allowing the U.S. Army to lift more, fly farther and maintain their aircraft better than ever before.”

She added: “This modernization program enables the battle-tested Chinook to play a key role in multi-domain operations going forward.”

The Block II upgrades include an improved drivetrain, reinforced airframe, and enhanced fuel system. These modifications increase the aircraft’s max gross weight by 4,000 pounds and extend its mission radius for nearly all payloads.

Viva Kelly, U.S. Army Cargo Helicopters acting project manager, stated: “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.”

The upgraded design also allows for future technology upgrades and improves aircraft sustainment. The new rotor system is more reliable, reducing unscheduled maintenance, while the simplified fuel system enhances efficiency and lowers maintenance costs.


This delivery represents a significant step in the U.S. Army’s ongoing efforts to modernize its helicopter fleet and maintain its operational readiness for future missions.
