C-17 GLOBEMASTER III
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 can perform tactical airlift and airdrop missions and can also transport litters and ambulatory patients during aeromedical evacuations 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 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 169,000 pounds (76,657 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 (.76 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 3,500 feet (1,064 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.
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 190 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 August 2005, March Air Reserve Base, Calif., began basing the first of eight aircraft. In February 2006, Hickam AFB, Hawaii, received its first C-17.
The C-17 is operated by the Air Mobility Command at the 60th Airlift Wing and the 349th Air Mobility Wing (Associate Reserve) at Travis AFB, Calif.; 62nd Airlift Wing and 446th Airlift Wing (Associate Reserve) at McChord AFB, Wash.; 437th Airlift Wing and 315th Airlift Wing (Associate Reserve) at Charleston AFB, S.C.; the 305th Air Mobility Wing, McGuire AFB, N.J.; and the 172nd Airlift Wing, Mississippi ANG. Additionally, Air Force Materiel Command operates two C-17s at Edwards AFB, Calif., and Pacific Air Forces operates eight aircraft each at Elmendorf AFB, Alaska and Hickam AFB, Hawaii (Associate Guard). The Air Force Reserve Command operates eight aircraft at March Air Reserve Base, Calif; and Air Education and Trainin
Redstone Ballistic Missile
The display reads:
REDSTONE BALLISTIC MISSILE
The Redstone Ballistic Missile, also known as the Surface to Surface Missile (SSM)-A-14, and Programmed Guided Missile (PGM)-11A, was a development from the German V-2 Rocket of the Second World War, and eventually named for Redstone Arsenal, Alabama, where it was designed. It met the U.S. Army's requirement for a ballistic missile that could outrange conventional artillery, development starting in 1951, and the first missile fired in August of 1953. The Redstone proved to be very reliable, and accurate, with thirty-five of the first thirty-eight missiles fired reaching the target. The missile's supersonic speed made it immune to any countermeasures known at the time.
The flight program was fed into the guidance system prior to launch, and the signals played back to the system during flight to control its trajectory. Accuracy was within a 1000 foot radius from the intended target. Due to its preprogrammed guidance system, the missile could not be diverted by exterior means.
The Redstone Missile was powered by a Rocketdyne A-6 engine, generating 78,000 pounds of thrust. This thrust could be controlled for 96 to 121 seconds to adjust range. The Rocketdyne engine burned a fuel composed of 75% alchol and 25% water, a motor driven by steam produced by hydrogen peroxide drove the turbopumps to provide the initial fuel pressure. The missile body and the thrust unit drop off at the end of the thrust phase allowing the more aerodynamic guidance module and warhead to continue to the target.
The firing of the Redstone missile is in four phases. They are:
Phase I: The thrust unit fires, propelling the entire missile towards the target.
Phase II: The thrust unit separates from the warhead / guidance section during flee flight. The thrust unit falling short of the target due to its lack of aerodynamic shape.
Phase III: Initial corrections are made to the trajectory of the warhead / guidance system module.
Phase IV: Final corrections are made during this terminal phase of flight.
The Redstone Missile System could be assembled, erected, fueled, aimed, and fired in less than two hours.
With research for the Pershing Missile System approved in 1958, the obsolescent Redstone was phased out of service, finally leaving in 1961.
