The U.S. Army has advanced its heavy-lift modernisation plans with an order for nine Boeing CH-47F Block II Chinook helicopters. The two new contracts, worth US$461 million, bring the total number of Block II aircraft on order to 18.
The latest awards, covering production Lots 4 and 5, follow the Army’s recent Rapid Fielding decision. Boeing is now working closely with the service to define the next stage, which will include Lot 6 production.
So far, Boeing has delivered six CH-47F Block II aircraft to the Army. These helicopters are undergoing detailed evaluations designed to confirm their improved performance and expanded capabilities.
The CH-47F Block II model includes major design upgrades. A strengthened drivetrain and airframe increase the helicopter’s maximum gross weight by 4,000 pounds, allowing for greater lift and payload capacity. The updated fuel system also extends range, enabling longer missions with heavier loads.
In addition to performance improvements, Boeing has introduced design features that simplify maintenance and lower sustainment costs. The enhancements ensure the Chinook can remain in service for at least another 40 years while allowing for affordable future upgrades.
The aircraft continues to play a vital role in the Army’s heavy-lift mission, supporting troops and equipment worldwide. The Block II programme underscores Boeing’s commitment to improving reliability, range, and efficiency in military rotorcraft operations.
With this new order, the Army reinforces its long-term confidence in the Chinook platform — a proven workhorse that has served across multiple generations of aviation technology. The Block II version represents the next step in ensuring that capability continues well into the future.
