Heavy-Lift Dominance

The H-47 Chinook is the heavy-lift helicopter of choice for the U.S. Army and 20 international operators. It is an advanced, multi-mission, tandem rotor helicopter, proven in cargo and troop transport, search and rescue, casualty evacuation, special operations, humanitarian and disaster relief, and more.

The tandem rotor design provides for increased stability and control, maximum agility, ease of loading and unloading and superior performance in wind. The Chinook can operate where others cannot. Rear ramp access on any terrain is not restricted by tail rotor clearance, allowing tandems to operate on unprepared, mountainous positions and execute the unique pinnacle landing capability. The design also allows the Chinook to fly at up to 20,000 feet, higher than other helicopters in its class.

It contains a fully integrated, digital cockpit management system – the Common Avionics Architecture System (CAAS) Cockpit paired with a Digital Automatic Flight Control System (DAFCS) – as well as advanced cargo-handling capabilities that complement the aircraft's mission performance and improve situational awareness.

Covering a vast amount of distance in a quick amount of time, the H-47 Chinook can be equipped with extended range fuel tanks and fitted for air-to-air refueling capability, meaning the Chinook can fly farther than ever before.

Modernized and Ready Now

To safely and effectively accomplish critical missions now and in the future, soldiers must have the most modernized heavy-lift solution. The H-47 Chinook Block II, the most advanced and capable heavy-lift aircraft in its class, is the only way to rapidly meet the warfighter’s ever-evolving needs. Boeing’s H-47 Chinook Block II is powered by cutting-edge technologies - redesigned fuel tanks, a strengthened fuselage, and an improved drivetrain, all of which enable soldiers to meet today’s heavy-lift mission requirements.

A Long-Term Solution

The Chinook Block II program positions the Army and international allies for long-term success. Not only is the Block II aircraft capable of meeting today’s heavy-lift requirements, it provides structural and design improvements that allow additional future upgrades to meet long-term heavy-lift needs.

Key investments in next generation technologies such as avionics open systems architecture and mission systems integration will enable decisive overmatch -- a critical advantage for the warfighter to succeed in Joint All-Domain Operations. Structural enhancements and vehicle power upgrades will keep the Chinook prepared to fight and win in all missions including large scale combat operations for decades to come.
