The Republic XF-103 was an American project to develop a powerful missile-armed interceptor aircraft capable of destroying Soviet bombers while flying at speeds as high as Mach 3. Despite a prolonged development, it never progressed past the mockup stage.
The Bréguet Br 960 Vultur was a prototype two-seat carrier-based attack and anti-submarine aircraft (ASW) built for the French Navy during the early 1950s. Meeting contradictory endurance and speed requirements, it was designed as a "mixed-power" aircraft with a turboprop engine in the front and a turbojet in the rear. Only two examples were built, but the second aircraft was rebuilt as the prototype of the Bréguet 1050 Alizé ASW aircraft after the Navy dropped the idea of a turboprop attack aircraft in the mid-1950s.
Major André Édouard Turcat was a French Air Force pilot and test pilot celebrated for flying the first prototype of Concorde for its maiden flight.
The Snecma Atar is a French axial-flow turbojet engine built by Snecma. It was derived from the German World War II BMW 018 design, and developed by ex-BMW engineers through a progression of more powerful models. The name is derived from its original design group, Atelier technique aéronautique de Rickenbach near Lindau within the French Occupation Zone of Germany. The Atar powered many of the French post-war jet aircraft, including the Vautour, Étendard and Super Étendard, Super Mystère and several models of the Mirage.
The Dassault MD.452 Mystère is a 1950s French fighter-bomber.
The SNCAC NC 1080 was a French jet-engined interceptor developed in the late 1940s by SNCAC for use aboard aircraft carriers. It was intended to compete for an Aéronavale contract and first flew in 1949. The aircraft used an innovative system of flight control surfaces that proved to be a failure during flight testing and had to be modified before it could fly again. Its development was troubled by other design flaws and the company's merger with SNCAN that same year. Further development was cancelled after a fatal crash destroyed the sole prototype in 1950.
The Leduc 0.10 was a research aircraft built in France, one of the world's first aircraft to fly powered solely by a ramjet.
The SNECMA C.450 Coléoptère was a tail-sitting vertical take-off and landing (VTOL) aircraft designed by the French company SNECMA and manufactured by Nord Aviation. While work on the aircraft proceeded to the test flying phase, the project never progressed beyond experimental purposes.
The Arsenal VG 70 was a single-seat monoplane research aircraft flown in France shortly after World War II to assist in the development of high-speed jet fighters. Lacking an indigenous turbojet engine, the aircraft was fitted with a German Junkers Jumo 004. Unlike most jet-powered aircraft of the period, the swept wing was wooden as was the tail structure. The under-powered VG 70 made its maiden flight in 1948, but only flew five times before the program was terminated the following year.
The Arsenal VG 90 was a French carrier-based jet-engined interceptor developed in the late 1940s. It was intended to compete for an Aéronavale contract and first flew in 1949. It set a speed record for a French aircraft the following year, but both of the completed prototypes were destroyed in fatal crashes and the program was cancelled in 1952 before the third prototype was finished. The Aéronavale contract was eventually awarded to a license-built British aircraft. The remains of the last VG 90 were scrapped in 1978.
The SNECMA Atar Volant or C.400 P1 was a French turbojet engine produced by SNECMA as part of their "Atar" series. Encased in a basic fairing which could hold fuel and remote-control equipment, the unit weighed 5,600 pounds (2,500 kg), and generated a thrust of approximately 6,200 pounds-force ; the Atar Volant was able to cause vertical lift, which was precisely its purpose. There were later Atar Volant models, each made improvements and alterations to the previous designs, and eventually resulted in a full-fledged craft.
The Nord Gerfaut (Gyrfalcon) was a French delta-wing experimental research aircraft. It was the first European aircraft to exceed Mach 1 in level flight without the use of an afterburner. A pair of aircraft were built for the primary purpose of investigating the transonic regime. The Gerfaut I conducted its maiden flight in 1954; it was followed by the improved Gerfaut II two years later. Both aircraft were flown for several years for experimental purposes, being significantly upgraded over time. During the course of these test flights, the second prototype establishment multiple time-to-altitude world records. In the late 1950s, the type was used to flight-test various aerial missiles. Both aircraft performed their final flights in 1959; they were subsequently used as targets at the Military Test Range at Cazaux.
The Leduc 0.21 was a research aircraft built in France in 1953 to refine the practicalities of ramjet propulsion. Initially proposed as the 0.20, it was essentially similar to its predecessor, the Leduc 0.10, but scaled up by around 30%, with tip tanks added to the wings. It was not capable of take-off under its own power, and had to be carried aloft and released.
The Leduc 022 was the prototype of a mixed-power French interceptor built in the mid-1950s. Designer René Leduc had been developing ramjet-powered aircraft since before World War II and had flown a series of experimental aircraft, the Leduc 0.10 and Leduc 0.21, throughout the 1950s before he was awarded a contract for two examples of a short-range supersonic interceptor armed with two air-to-air missiles (AAMs).
The SNCASE S.E.5000 Baroudeur was a French single-engined lightweight fighter designed by SNCASE (Sud-Est) for the NATO NBMR-1 "Light Weight Strike Fighter" competition. An unusual design without a conventional landing gear, it used a wheeled trolley for take-off and three retractable skids to land. The Baroudeur did not enter production.
The Nord 2200 was a French carrier-based, jet-engined interceptor developed in the late 1940s. It was intended to compete for an Aéronavale contract, but was not selected for production after a 1950 accident badly damaged the sole prototype. It was repaired and resumed flight testing the following year, which including evaluating rocket-assisted take offs. After the aircraft made its last flight in 1954, it was used as a gunnery target. Much of the airframe was recovered in the 1980s, but its current disposition is uncertain.
The SNECMA ATAR 101 is a French axial-flow turbojet engine built by SNECMA. It was derived from engines and design work carried out at BMW in Germany during World War II, and extensively developed though a progression of more powerful models. The name is derived from its original design group, Atelier Technique Aéronautique de Rickenbach employing Hermann Östrich and many of the wartime BMW gas turbine design group as well as other German engine design teams. The ATAR 101 powered many of the French post-war jet aircraft, including the Vautour II, Étendard IV, Super Mystère B2, and the Mirage III-001, prototype of the Mirage III series.
The SNCASO SO.9000 Trident is a French mixed-power interceptor aircraft built by aircraft manufacturer SNCASO during the 1950s. As part of a wider effort to re-build French military power during the late 1940s and to furnish France with advanced, new domestically produced designs, a request for a supersonic-capable point-defence interceptor aircraft to equip the French Air Force was issued to SNCASO. In response, the firm designed the mixed-propulsion Trident, powered by a single SEPR rocket engine, which was augmented by wingtip-mounted turbojet engines, and the Air Force ordered two prototypes.
The Nord Aviation CT20 was a French turbojet-powered radio-controlled target drone introduced in 1957. Developed from the Arsenal / S.F.E.C.M.A.S. T.5.510, the CT.20 was built by Nord Aviation and powered by a Turbomeca Marboré II engine, providing a top speed of 900 km/h and a flying time of 55 to 60 minutes. It has been noted for its similarity to the Ryan Firebee. The unmanned drone was used in the development of air-to-air missiles following the Second World War.
The Sud-Ouest SO.6020 Espadon (Swordfish) was a French post-war prototype interceptor designed and built by SNCASO during the late 1940s. The French Air Force judged the design a failure despite some records being set and cancelled plans to put it into service in 1951. Only four aircraft were built and they were later modified to serve as testbeds for the mixed rocket and turbojet-powered SNCASO SO.9000 Trident program. Only one badly damaged aircraft survives.
