The US Army has awarded Boeing a contract worth $461 million to deliver nine CH-47F Block II Chinook helicopters, reinforcing its heavy-lift modernization effort. The order, which covers production Lots 4 and 5, brings the total number of Block II Chinooks on order to 18 aircraft. The acquisition aligns with the Army’s plan to enhance lift capacity and improve operational readiness for troop and cargo transport missions.
Boeing has already delivered six Block II helicopters, which are undergoing extensive performance and endurance testing before being cleared for full operational deployment. The US Army and Boeing are reportedly in discussions for a potential Lot 6 order, signaling the service’s intent to accelerate the rollout of the upgraded fleet.
Each CH-47F Block II incorporates enhanced structural reinforcements, a new fuel system design, and upgraded engines and drive components. These improvements collectively raise the helicopter’s maximum takeoff weight by 4,000 pounds (1,814 kilograms) and extend its operational range, allowing for heavier payloads and longer mission endurance. The Army plans to assign the aircraft to two combat aviation brigades as part of its broader aviation modernization roadmap.
The CH-47F Chinook remains one of the world’s most capable transport helicopters, measuring 98 feet (30 meters) in length with a rotor diameter of 80 feet (18 meters). Powered by twin Honeywell T55-GA-714A engines generating 4,700 horsepower each, the aircraft achieves a top speed of 170 knots (315 km/h) and can carry up to 55 troops or 24,000 pounds (10,886 kilograms) of cargo. Boeing is also fulfilling contracts for more than 50 MH-47G variants tailored for the US Special Operations Command (SOCOM).
