The US Army has awarded Boeing a contract for 6 new CH-47F medium transport helicopters, plus the remanufacture of 22 current Chinooks to the F-standard. The contract is worth 617 million USD and estimate completion date is 31 December 2020.

Chinook helicopters were introduced in 1962 as the CH-47 Chinook, and models A, B and C were deployed in Vietnam. As the product of a modernization program, which included refurbishing existing CH-47s, the first CH-47Ds were delivered in 1982 and were produced until 1994. A central element in the Gulf War, they continue to be the standard for the US Army. Since its introduction 1,179 Chinooks have been built. The US Army has a requirement of 215 CH-47Fs.

The most modern CH-47F features a newly designed, modernized airframe, a Rockwell Collins Common Avionics Architecture System (CAAS) cockpit and a BAE Digital Advanced Flight Control System (DAFCS). According to Boeing the CAAS greatly improves aircrew situational awareness, while DAFCS provides improved flight-control capabilities through the entire flight envelope, significantly improved performance, and safety in the harshest of environments.

CAAS also incorporates an advanced digital map display and a data transfer system that allows storing of preflight and mission data. Improved survivability features include the Common Missile Warning and Improved Countermeasure Dispenser systems.

Powered by two 4,733-horsepower Honeywell engines, the new CH-47F can reach speeds greater than 175 mph and transport more than 21,000 pounds. The CH-47F, with its Robertson Aviation Extended Range Fuel System, has a mission radius of more than 400 nautical miles.

The Foxtrot Chinook has also been sold to the United Kingdom (24), Canada (15; CH-147F), Australia (15) and the Netherlands (6 new + 11 upgraded D-models).

Just two days before the new Chinook deal for Boeing, Sikorsky received word from Washington worth US$ 723,998,360 to modify 33 current US Army helicopters to UH-60M Black Hawk and another 24 to HH-60M standard.
