C-17 GlobeMaster III

Reliability and maintainability are 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.

The C-17 measures 174 feet long (53 meters) with a wingspan of 169 feet, 10 inches (51.75 meters). 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. 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.

The aircraft is operated by a crew of three (pilot, copilot and loadmaster), reducing manpower requirements, risk exposure and long-term operating costs. 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 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.

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.

Background Information

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.

C-141 Starlifter

The C-141B is a "stretched" C-141A with in-flight refueling capability. The stretching of the Starlifter consisted of lengthening the planes 23 feet 4 inches (7.11 meters). The added length increased the C-141 cargo capacity by about one-third, for an extra 2,171 cubic feet (62.03 cubic meters). The lengthening of the aircraft had the same overall effect as increasing the number of aircraft by 30 percent. The C-141A, built between 1963 and 1967, was AMC's first jet aircraft designed to meet military standards as a troop and cargo carrier. The development of the B model was the most cost-effective method of increasing AMC's airlift capability. The C-141C includes the addition of advanced avionics.

A universal air refueling receptacle on the C-141, with the ability to transfer 23,592 gallons (89,649.6 liters) in about 26 minutes, means longer non-stop flights and fewer fuel stops at overseas bases during worldwide airlift missions.

With more than 40 years of service and nearly nine million flying hours, the C-141 force has a proven reliability and long-range capability. In addition to training, worldwide airlift and combat support, the C-141 has amassed a laudatory record in response to humanitarian crises.

The C-141, with its changeable cargo compartment, can transition from rollers on the floor for palletized cargo to a smooth floor for wheeled vehicles to aft facing seats or sidewall canvas seats for passengers, quickly and easily, to handle over 30 different missions.

Background

The first C-141A, delivered to Tinker AFB, Okla., in October 1964, began squadron operations in April 1965. The C-141 was the first jet transport from which U.S. Army paratroopers jumped, and the first to land in the Antarctic. The first C-141B was received by the Air Force in December 1979. Conversion from A to B models was completed in 1982. Conversion to the C-models began in 1997 and was completed in 2001.

The last active-duty C-141B retired Sept. 16, 2004, at McGuire AFB, N.J. AMC began transferring C-141s to the Air Reserve and Air National Guard forces in July 1986. There are 20 Reserve C-141C's are stationed at Wright-Patterson AFB, Ohio, and March Air Reserve Base, Calif.

The C-141 continues to be a valuable asset to military aeromedical evacuation and airlift. The C-141's capabilities help enable AMC to meet any commitment anywhere national interest dictates.

C-130 Hercules

Using its aft loading ramp and door the C-130 can accommodate a wide variety of oversized cargo, including everything from utility helicopters and six-wheeled armored vehicles to standard palletized cargo and military personnel. In an aerial delivery role, it can airdrop loads up to 42,000 pounds or use its high-flotation landing gear to land and deliver cargo on rough, dirt strips.

The flexible design of the Hercules enables it to be configured for many different missions, allowing for one aircraft to perform the role of many. Much of the special mission equipment added to the Hercules is removable, allowing the aircraft to revert back to its cargo delivery role if desired. Additionally, the C-130 can be rapidly reconfigured for the various types of cargo such as palletized equipment, floor-loaded material, airdrop platforms, container delivery system bundles, vehicles and personnel or aeromedical evacuation.

The C-130J is the latest addition to the C-130 fleet and will replace aging C-130E's. The C-130J incorporates state-of-the-art technology to reduce manpower requirements, lower operating and support costs, and provides life-cycle cost savings over earlier C-130 models. Compared to older C-130s, the J model climbs faster and higher, flies farther at a higher cruise speed, and takes off and lands in a shorter distance. The C-130J-30 is a stretch version, adding 15 feet to fuselage, increasing usable space in the cargo compartment.

C-130J/J-30 major system improvements include: advanced two-pilot flight station with fully integrated digital avionics; color multifunctional liquid crystal displays and head-up displays; state-of-the-art navigation systems with dual inertial navigation system and global positioning system; fully integrated defensive systems; low-power color radar; digital moving map display; new turboprop engines with six-bladed, all-composite propellers; digital auto pilot; improved fuel, environmental and ice-protection systems; and an enhanced cargo-handling system.

Background

Four decades have elapsed since the Air Force issued its original design specification, yet the remarkable C-130 remains in production. The initial production model was the C-130A, with four Allison T56-A-11 or -9 turboprops. A total of 219 were ordered and deliveries began in December 1956. The C-130B introduced Allison T56-A-7 turboprops and the first of 134 entered Air Force service in May 1959.

Introduced in August of 1962, the 389 C-130E's that were ordered used the same Allison T56-A-7 engine, but added two 1,290 gallon external fuel tanks and an increased maximum takeoff weight capability. June 1974 introduced the first of 308 C-130H's with the more powerful Allison T56-A-15 turboprop engine. Nearly identical to the C-130E externally, the new engine brought major performance improvements to the aircraft.

The latest C-130 to be produced, the C-130J entered the inventory in February 1999. With the noticeable difference of a six-bladed composite propeller coupled to a Rolls-Royce AE2100D3 turboprop engine, the C-130J brings substantial performance improvements over all previous models, and has allowed the introduction of the C-130J-30, a stretch version with a 15-foot fuselage extension. Air Force has selected the C-130J-30 to replace retiring C-130E's. Approximately 168 C-130J/J-30s are planned for the inventory. To date, the Air Force has taken delivery of 32 C-130J aircraft from Lockheed Martin Aeronautics Company with orders for approximately 46 more aircraft.
