Major Acquisition Programs: Chinook Cargo Helicopter (CH-47)

What is it? The Chinook Cargo Helicopter (CH-47) is a twin-turbine, tandem-rotor, heavy-lift transport helicopter with a useful load of up to 25,000 pounds. The Chinook entered Army service in the early 1960s with a CH-47A, B, or C model designation. From 1980 through 1993, the early model aircraft were remanufactured to the current CH-47D configuration. Today, 46 percent of the Army's CH-47D fleet was originally manufactured prior to 1966. As the Army's only heavy lift helicopter, the mission of the CH-47 is to transport troops (including air assault), supplies, weapons, and other cargo in combat, combat support and service support operations.

What has the Army done? Key modifications integrated into the CH-47F include:

- A new-machined airframe,
- An upgraded T55-GA-714A engine to restore performance capability,
- Common Avionics Architecture System,
- Air Warrior, Common Missile Warning System,
- Enhanced air transportability features,
- Digital automatic flight control system (DAFCS), and
- An Extended Range Fuel System II for self-deployment missions.

The CH-47F also incorporates reliability and maintainability improvements including airframe tuning for vibration reduction, corrosion protection, digital source collectors, and an automated maintenance program with a 400-hour phase interval.

What efforts does the Army plan to continue in the future? The CH-47F is expected to remain the Army's heavy lift helicopter until at least the 2020-2025 timeframe.
