Boeing has secured an $876.4-million contract to supply up to 60 CH-47F Chinook heavy-lift helicopters to the US Army.
The deal includes performance-based logistics, training, and non-recurring engineering.
Work will be carried out in Ridley Park, Pennsylvania, and is expected to be completed by October 2035.
The army’s Contracting Command at Redstone Arsenal, Alabama, will coordinate the progress of the order, with payment sourced from fiscal 2026 Germany case funds.
Block II Versions
The CH-47F orders included in this contract are all Block II, a modernized version of the Chinook designed to improve performance, range, and survivability.
This configuration features a strengthened airframe, an upgraded drivetrain, a redesigned fuel system, and enhanced avionics. These improvements also allow for a higher payload capacity.
Block II also includes updated flight controls with a Digital Advanced Flight Control System, improved electrical systems, and provisions for future upgrades.
The US Army plans to eventually upgrade more than 400 CH-47F Block I helicopters in its arsenal to the Block II standard.
Prior to the latest contract, Boeing received a $461-million deal last month for nine CH‑47F Block II Chinooks, and a separate $135 million order in December 2024 to build and deliver three additional platforms.
The CH-47F Chinook
Boeing’s CH-47F helicopter design is 98 feet (30 meters) in length and has a rotor diameter of 80 feet (18 meters).
It can carry up to 55 people, approximately 24,000 pounds (10,886 kilograms) of cargo, or about 20 medical stretchers, depending on mission requirements.
The aircraft is operated by a crew of three and is powered by twin Honeywell T55-GA-714A engines with an output of about 4,700 horsepower each.
The helicopter has a maximum speed of 170 knots (196 miles/315 kilometers per hour), a range of 1,200 nautical miles (1,399 miles/2,252 kilometers), and a service ceiling of 20,000 feet (6,096 meters).
