The Northrop Grumman E-8 Joint Surveillance Target Attack Radar System is a retired United States Air Force (USAF) airborne ground surveillance, battle management and command and control aircraft. It tracks ground vehicles and some aircraft, collects imagery, and relays tactical pictures to ground and air theater commanders. The aircraft was operated by both active duty USAF and Air National Guard units and also carried specially trained U.S. Army personnel as additional flight crew until its retirement in 2023.
The Boeing KC-135 Stratotanker is an American military aerial refueling tanker aircraft that was developed from the Boeing 367-80 prototype, alongside the Boeing 707 airliner. It has a narrower fuselage and is shorter than the 707. Boeing gave the aircraft the internal designation of Model 717. The KC-135 was the United States Air Force (USAF)'s first jet-powered refueling tanker and replaced the KC-97 Stratofreighter. The KC-135 was initially tasked with refueling strategic bombers, but it was used extensively in the Vietnam War and later conflicts such as Operation Desert Storm to extend the range and endurance of US tactical fighters and bombers.
The Boeing 707 is an early American long-range narrow-body airliner, the first jetliner developed and produced by Boeing Commercial Airplanes. Developed from the Boeing 367-80 prototype first flown in 1954, the initial 707-120 first flew on December 20, 1957. Pan Am began regular 707 service on October 26, 1958. With versions produced until 1979, the 707 was a swept wing quadjet with podded engines. Its larger fuselage cross-section allowed six-abreast economy seating, retained in the later 720, 727, 737, and 757 models.
Air Force One is the official air traffic control designated call sign for a United States Air Force aircraft carrying the president of the United States. In common parlance, the term is used to denote U.S. Air Force aircraft modified and used to transport the president, and as a metonym for the primary presidential aircraft, VC-25, although it can be used to refer to any Air Force aircraft the president travels on.
The Douglas DC-6 is a piston-powered airliner and cargo aircraft built by the Douglas Aircraft Company from 1946 to 1958. Originally intended as a military transport near the end of World War II, Douglas reworked it after the war to compete with the Lockheed Constellation in the long-range commercial transport market. Douglas built over 700, and many still fly in cargo, military, and wildfire control roles.
The Boeing VC-25 is a military version of the Boeing 747 airliner, modified for presidential transport and commonly operated by the United States Air Force (USAF) as Air Force One, the call sign of any U.S. Air Force aircraft carrying the president of the United States.
The Boeing C-97 Stratofreighter was a long-range heavy military cargo aircraft developed from the B-29 and B-50 bombers. Design work began in 1942, the first of three prototype XC-97s flew on 9 November 1944 and the first of six service-test YC-97s flew on 11 March 1947. All nine were based on the 24ST alloy structure and Wright R-3350 engines of the B-29, but with a larger-diameter fuselage upper lobe and they had the B-29 vertical tail with the gunner's position blanked off. The first of three heavily revised YC-97A incorporating the re-engineered wing, taller vertical tail and larger Pratt & Whitney R-4360 engines of the B-50 bomber, flew on 28 January 1948 and was the basis of the subsequent sole YC-97B, all production C-97s, KC-97s and civilian Stratocruiser aircraft. Between 1944 and 1958, 888 C-97s in several versions were built, 811 being KC-97 tankers. C-97s served in the Berlin Airlift, the Korean War, and the Vietnam War. Some aircraft served as flying command posts for the Strategic Air Command, while others were modified for use in Aerospace Rescue and Recovery Squadrons (ARRS).
The Pratt & Whitney JT3D is an early turbofan aircraft engine derived from the Pratt & Whitney JT3C. It was first run in 1958 and was first flown in 1959 under a B-45 Tornado test aircraft. Over 8,000 JT3Ds were produced between 1959 and 1985. Most JT3D engines still in service today are used on military aircraft, where the engine is referred to by its US military designation of TF33.
The Boeing C-135 Stratolifter is a transport aircraft derived from the prototype Boeing 367-80 jet airliner in the early 1950s. It has a narrower fuselage and is shorter than the 707. Boeing gave the aircraft the internal designation of Model 717, a name later assigned to a completely different aircraft.
Air Force Two is the air traffic control designated call sign held by any United States Air Force aircraft carrying the vice president of the United States, but not the president. The term is often associated with the Boeing C-32, a modified 757 which is most commonly used as the vice president's transport. Other 89th Airlift Wing aircraft, such as the Boeing C-40 Clipper, C-20B, C-37A, and C-37B, have also served in this role. The VC-25A, the aircraft most often used by the president as Air Force One, has also been used by the vice president as Air Force Two.
The Boeing CC-137 is a retired transport and tanker aircraft which served with the Canadian Forces from 1970 to 1997. The Boeing 707-347C aircraft provided long range passenger transport for the military, VIP transport for government and air-to-air refueling for fighters such as the CF-116 Freedom Fighter and CF-18 Hornet. It was replaced by the Airbus CC-150 Polaris in the transport role and much later in the tanker role.
The Boeing EC-135 is a retired family of command and control aircraft derived from the Boeing C-135 Stratolifter. During the Cold War, the EC-135 was best known for being modified to perform the Looking Glass mission where one EC-135 was always airborne 24 hours a day to serve as flying command post for the Strategic Air Command in the event of nuclear war. Various other EC-135 aircraft sat on airborne and ground alert throughout the Cold War, with the last EC-135C being retired in 1998. The EC-135N variant served as the tracking aircraft for the Apollo program.
The 1254th Air Transport Wing was a United States Air Force unit, existing between 1948 and 1966. It was last stationed at Andrews AFB, Maryland.
SAM 27000 was the second of two Boeing VC-137C United States Air Force aircraft that were specifically configured and maintained for the use of the president of the United States. It used the call sign Air Force One when the president was on board, and at other times it used the call sign SAM 27000, with SAM indicating 'Special Air Mission.' The VC-137C serial number 72-7000 was a customized version of the Boeing 707 which entered service during the Nixon administration in 1972. It served all US presidents until George W. Bush and was retired in 2001. It is now on display at the Ronald Reagan Presidential Library.
SAM 26000 was the first of two Boeing VC-137C United States Air Force aircraft specifically configured and maintained for use by the President of the United States. It used the callsign Air Force One when the president was on board, otherwise SAM 26000, with SAM indicating Special Air Mission.
The United States Air Force Special Air Mission provides air transportation for the president of the United States (POTUS), vice president of the United States (VPOTUS), first lady of the United States (FLOTUS), presidential Cabinet, U.S. congressional delegations (CODELs), and other high-ranking American and foreign dignitaries.
The Lockheed C-121 Constellation is a military transport version of the Lockheed Constellation. A total of 332 aircraft were constructed for both the United States Air Force and United States Navy for various purposes. Numerous airborne early warning versions were also constructed. The C-121 later saw service with smaller civilian operators until 1993.
The 34th Strategic Squadron is an inactive United States Air Force unit. It was last assigned to the 11th Strategic Group at Zaragoza Air Base, Spain. It was inactivated on 7 August 1990.
The Lockheed L-193 Constellation II was a jet airliner design concept, designed between 1949 and 1953 with a swept wing and engines mounted at the tail. An airliner and tanker version were developed. The latter, in an aerial refueling competition initiated by the United States Air Force (USAF), won and was preferred over the Boeing KC-135 Stratotanker. Since the competing Boeing aircraft was ready to fly first, examples were ordered as an interim measure. They performed well enough that the L-193 was never ordered as a tanker, and airliner plans were dropped soon after.
