The Convair X-6 was a proposed experimental aircraft project to develop and evaluate a nuclear-powered jet aircraft. The project was to use a Convair B-36 bomber as a testbed aircraft, and though one NB-36H was modified during the early stages of the project, the program was canceled before the actual X-6 and its nuclear reactor engines were completed. The X-6 was part of a larger series of programs, costing US$7 billion in all, that ran from 1946 through 1961. Because such an aircraft's range would not have been limited by liquid jet fuel, it was theorized that nuclear-powered strategic bombers would be able to stay airborne for weeks at a time.
The Lockheed CL-1200 Lancer was a late 1960s company-funded proposal for a fighter aircraft based on the Lockheed F-104 Starfighter. The CL-1200 was conceived and marketed mainly for and to non-US military services, as an export product. As such it would have competed with combat-proven designs like the Dassault Mirage III, McDonnell Douglas F-4 Phantom II, Mikoyan-Gurevich MiG-21, and Northrop F-5E Tiger II. The CL-1200 competed unsuccessfully against proposed fourth generation designs, under the US government's Lightweight Fighter program, which would eventually result in the General Dynamics F-16 and Northrop F-17 Cobra.
A nuclear-powered aircraft is a concept for an aircraft intended to be powered by nuclear energy. The intention was to produce a jet engine that would heat compressed air with heat from fission, instead of heat from burning fuel. During the Cold War, the United States and Soviet Union researched nuclear-powered bomber aircraft, the greater endurance of which could enhance nuclear deterrence, but neither country created any such operational aircraft.
The Canadair CP-107 Argus is a maritime patrol aircraft designed and manufactured by Canadair for the Royal Canadian Air Force (RCAF). The Argus served throughout the Cold War in the RCAF's Maritime Air Command and later the Canadian Force's Maritime Air Group and Air Command.
The Shaanxi Y-8 or Yunshuji-8 aircraft is a medium size medium range transport aircraft produced by Shaanxi Aircraft Corporation in China, based on the Soviet Antonov An-12. It has become one of China's most popular military and civilian transport/cargo aircraft, with many variants produced and exported. Although the An-12 is no longer made in Ukraine, the Chinese Y-8 continues to be upgraded and produced. An estimated 169 Y-8 aircraft had been built by 2010.
The Tupolev Tu-95LAL experimental aircraft which flew from 1961 to 1965 was a modified Tupolev Tu-95 Soviet bomber aircraft, analogous to the United States' earlier Convair NB-36H. It was intended to see whether a nuclear reactor could be used to power an aircraft, primarily testing airborne operation of a reactor and shielding for components and crew. The reactor did not actually power the aircraft.
An airborne aircraft carrier is a type of mother ship aircraft which can carry, launch, retrieve and support other smaller parasite aircraft.
The AQM-60 Kingfisher, originally designated XQ-5, was a target drone version of the USAF's X-7 ramjet test aircraft built by the Lockheed Corporation. The aircraft was designed by Kelly Johnson, who later created the Lockheed A-12 and its relatives, such as the Lockheed SR-71 Blackbird and Lockheed YF-12.
The Bristol Tramp was a British steam-powered passenger and airmail transport aircraft designed by the Bristol Aeroplane Company. It was built but never flew.
The Shaanxi Y-9 is a medium military transport aircraft produced by Shaanxi Aircraft Company in China. It is a stretched and upgraded development of the Shaanxi Y-8F.
The Ling-Temco-Vought XQM-93 was a remotely piloted aircraft developed in the United States in the late 1960s and early 1970s for use as a communications relay in the Vietnam War. A prototype flew in 1970, but the program was abandoned without producing a service-ready aircraft.
The Mikoyan Skat is a concept of a stealth unmanned combat aerial vehicle (UCAV) being developed by Mikoyan for the Russian Ministry of Defence since 2005.
The Lockheed C-69 Constellation is a four-engined, propeller-driven military transport aircraft developed during World War II. It was co-developed with the Lockheed Constellation airliner.
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 Lockheed L-1249 Super Constellation was a turboprop-powered version of the Lockheed Constellation aircraft family. Built in 1954 and 1955, the aircraft were used as prototypes for possible future military transport aircraft for both the United States Air Force and United States Navy. Both aircraft saw very short lives and the airframes were later used to build L-1049 Super Constellations.
The Blohm & Voss P.208 was a design project for a tailless swept-wing propeller-powered interceptor designed by the German company Blohm & Voss towards the end of the Second World War.
The Lockheed Martin X-44A is an unmanned aerial vehicle (UAV) technology demonstrator built by the Lockheed Martin Skunk Works.
The Messerschmitt P.1107 was a jet-powered bomber project developed in the final years of the Second World War.
The Allison T78 was a turboprop engine that first ran in March 1965. It used a regenerator that recovered and reused exhaust heat to reduce fuel consumption.
