The
latest fact sheets for C-17 Globemaster III show Background, Mission,General
Characteristics, and
the Features
as
the Following:
Background:
The
C-17 made its maiden flight on Sept. 15, 1991, and the first
production model was delivered to Charleston Air Force Base,
S.C., June 14, 1993.
The first squadron of C-17s, the 17th Airlift Squadron,
was declared operationally ready Jan. 17, 1995. The Air Force
originally programmed to buy a total of 120 C-17s, with the
last one being delivered in November 2004. Current budget plans
involve purchasing 180 aircraft. The original 120 C-17s were
based at Charleston AFB; McChord AFB, Wash., (first aircraft
arrived in July 1999); Altus AFB, Okla.; and at an Air National
Guard unit in Jackson, Miss. In September 2004, McGuire AFB,
N.J. began basing the first of 13 aircraft expected by June
2005.
The C-17 is operated by the Air Mobility Command at the
437th Airlift Wing, Charleston AFB, S.C.; the 62nd Airlift Wing,
McChord AFB, Wash; the 305th Air Mobility Wing, McGuire AFB,
N.J.; the 315th Airlift Wing (Associate Reserve), Charleston
AFB, S.C.; and, the 446th Airlift Wing (Associate Reserve),
McChord AFB, Wash; and the 172nd Airlift Wing, Mississippi ANG.
Additionally, Air Force Materiel Command operates one C-17 at
Wright-Patterson AFB, Ohio; and Air Education and Training Command
operates eight aircraft at Altus AFB, Okla.
Mission:
The
C-17 Globemaster III is the newest, most flexible cargo aircraft
to enter the airlift force. The C-17 is capable of rapid strategic
delivery of troops and all types of cargo to main operating
bases or directly to forward bases in the deployment area. The
aircraft is also capable of performing tactical airlift and
airdrop missions when required. The inherent flexibility and
performance of the C-17 force improve the ability of the total
airlift system to fulfill the worldwide air mobility requirements
of the United States.
The ultimate measure of airlift effectiveness
is the ability to rapidly project and sustain an effective combat
force close to a potential battle area. Threats to U.S. interests
have changed in recent years, and the size and weight of U.S.-mechanized
firepower and equipment have grown in response to improved capabilities
of potential adversaries.
This
trend has significantly increased air mobility requirements,
particularly in the area of large or heavy outsize cargo. As
a result, newer and more flexible airlift aircraft are needed
to meet potential armed contingencies, peacekeeping or humanitarian
missions worldwide. The C-17 is capable of meeting today’s demanding
airlift missions.

Reliability
and maintainability |
Two outstanding benefits of the C-17 system.
Current operational requirements impose demanding reliability and
maintainability.
These requirements include an aircraft mission completion success
probability rate of 92 percent, only 20 aircraft maintenance man-hours
per flying hour, and full and partial mission availability rates
of 74.7 and 82.5 percent, respectively.
The Boeing warranty assures these figures will be met. |
Measures
|
174
feet long (53 meters) with a wingspan of 169 feet, 10 inches (51.75
meters).
|
Engines
|
The
aircraft is powered by four, fully reversible, Federal Aviation
Administration-certified F117-PW-100 engines
(the military designation for the commercial Pratt & Whitney PW2040),
currently used on the Boeing 757. |
Thrust |
Each
engine is rated at 40,440 pounds of thrust. The thrust reversers
direct the flow of air upward and forward to avoid ingestion of
dust and debris. Maximum use has been made of off-the-shelf and
commercial equipment, including Air Force-standardized avionics.
|
COCKPIT
|
The
aircraft is operated by a crew of three (pilot, copilot and loadmaster),
reducing manpower requirements, risk exposure and long-term operating
costs. |
Cargo
Compartment - Capacity
|
Cargo
is loaded onto the C-17 through a large aft door that accommodates
military vehicles and palletized cargo. The C-17 can carry virtually
all of the Army's air-transportable equipment. |
Maximum
payload capacity |
Maximum
payload capacity of the C-17 is 170,900 pounds (77,519 kilograms),
and its maximum gross takeoff weight is 585,000 pounds (265,352
kilograms).
With a payload of 160,000 pounds (72,575 kilograms) and an initial
cruise altitude of 28,000 feet (8,534 meters),the C-17 has an unrefueled
range of approximately 2,400 nautical miles.
Its cruise speed is approximately 450 knots (.74 Mach). The C-17
is designed to airdrop 102 paratroopers and equipment. |
Design
|
The
design of the aircraft allows it to operate through small, austere
airfields. The C-17 can take off and land on runways as short as
3,000 feet (914 meters) and only 90 feet wide (27.4 meters). Even
on such narrow runways, the C-17 can turn around using a three-point
star turn and its backing capability. . |
C-17success
is based on outstanding performance and adding value to the C-17
Program. “Value” is defined as products that consistently meet customer
expectations through continuous improvement, integration and people.
Other
success factors include customer satisfaction with C-17 responsiveness
to and effectiveness of action requests.
Key
sources of comparative/competitive data for C-17 include:
State Quality
Award Program Winners,
Malcolm Baldrige National Winners, Supplier Certification, Requirements/Levels
• Long Beach Supplier data (external and internal), Aircraft Industry
Association (AIA) • Bureau of Labor Statistics, Industry Week’s
Best Plants Statistics.
It
is positive to see C17 III is capable of performing tactical
airlift and airdrop missions when required. The inherent flexibility
and performance of the C-17 force improve the ability of the total
airlift system to fulfill the worldwide air mobility requirements
of the United States and where it's needed. The C-17 is capable
of meeting today’s demanding airlift missions.
