The US Army has made a significant move towards modernizing its heavy-lift capabilities by placing an order for nine new CH-47F Block II Chinook helicopters from Boeing. This acquisition, valued at $461 million, is part of an ongoing initiative aimed at enhancing the Army’s ability to transport troops and equipment efficiently. With this latest contract, which pertains to production Lots 4 and 5, the total count of Block II Chinooks ordered has now reached 18.
The need for upgraded Chinook helicopters stems from the Army’s strategic decision to expedite the deployment of these advanced aircraft. Following discussions on a potential Lot 6 order, both the Army and Boeing are moving swiftly to ensure that the new models are operational as soon as possible.
As for the upgraded features, Boeing has thus far delivered six Block II Chinooks, which are currently undergoing performance tests to validate their enhancements prior to full deployment. Notable improvements in the Block II versions include reinforced internal structures, a redesigned fuel system, and upgraded engines and drive components. These modifications collectively increase the helicopter’s maximum takeoff weight by 4,000 pounds (1,814 kilograms), thereby extending its operational flight range and allowing it to carry heavier loads over longer distances.
The US Army plans to integrate the new Chinooks into two combat aviation brigades, emphasizing a long-term strategy for modernization. This initiative also coincides with Boeing receiving orders for over 50 MH-47G variants specifically for the US Special Operations Command, underscoring the importance of the Chinook within the Army’s operational framework.
Heather McBryan, Vice President and Program Manager for Cargo Programs at Boeing Defense, Space and Security, remarked on the rapid succession of contracts, suggesting that the Chinook will continue to play a crucial role in the Army’s logistics operations, particularly in challenging environments. She highlighted the company’s appreciation for its partnership with the Army and the support from Congress in delivering these upgraded capabilities to military personnel.
The CH-47F Chinook is an impressive piece of machinery, measuring 98 feet (30 meters) in length with a rotor diameter of 80 feet (18 meters). It is capable of transporting up to 55 troops or approximately 24,000 pounds (10,886 kilograms) of cargo efficiently. The aircraft is operated by a crew of three and can accommodate over 20 standard stretchers for medical missions, making it a versatile asset on the battlefield.
Powered by twin Honeywell T55-GA-714A engines, which each generate about 4,700 horsepower, the CH-47F can operate at altitudes of up to 20,000 feet (6,096 meters) and has a range of 1,200 nautical miles (1,399 miles/2,252 kilometers). Additionally, it can reach speeds of 170 knots (196 miles/315 kilometers per hour), further enhancing its utility in various military operations.
