C-17 Globemaster III

The Boeing C-17 Globemaster III is designed to fulfill military and humanitarian airlift needs well into the 21st century. A high-wing, four-engine, T-tailed aircraft with a rear-loading ramp, the C-17 can carry large combat equipment and troops or humanitarian aid across international distances directly to small austere airfields anywhere in the world.

With a payload of 164,900 pounds, the C-17 can take off from a 7,000-foot airfield, fly 2,400 nautical miles, and land on a small, austere airfield of 3,000 feet or less. The C-17 is equipped with an externally blown flap system that allows a steep, low-speed final approach and low-landing speeds for routine short-field landings.

Customers:
Worldwide, Boeing has delivered 248 C-17s as of November 2012. Boeing’s program of record with the U.S. Air Force is to design, build and deliver 224 C-17s.

A cockpit crew of two and one loadmaster operate the C-17, which can be refueled in flight. This cost-effective flight crew complement is made possible through the use of an advanced digital avionics system and advanced cargo systems. In the cargo compartment, the C-17 can carry Army wheeled vehicles in two side-by-side rows. Three combat-ready Stryker infantry-fighting vehicles comprise one deployment load. Similarly, the Army's newest main battle tank, the M-1, can be carried.

The four engines are Pratt & Whitney PW2040 series turbofans, designated as F117-PW-100 by the Air Force, each producing 40,440 pounds of thrust. The engines are equipped with directed-flow thrust reversers capable of deployment in flight. On the ground, a fully loaded aircraft using thrust reversers can back up a 2 percent slope.

Background:
On Dec. 10, 2010, the worldwide C-17 fleet surpassed the 2 million flight-hours milestone. The U.S. Air Force declared the first C-17 squadron operational in January 1995, following first flight in 1991. C-17s have been involved in numerous contingency operations, including flying troops and equipment to Operation Joint Endeavor to support peacekeeping in Bosnia, Allied Force Operation in Kosovo, Operation Enduring Freedom in Afghanistan and Operation Iraqi Freedom.

During flight-testing at Edwards Air Force Base, Calif., C-17s set 33 world records – more than any other airlifter in history – including payload to altitude, time-to-climb and short-takeoff-and-landing marks in which the C-17 took off in less than 1,400 feet, carried a payload of 44,000 pounds to altitude and landed in less than 1,400 feet.
