Mirage was a name given to several types of jet aircraft designed by the French company Dassault Aviation (formerly Avions Marcel Dassault), some of which were produced in different variants.
 Most were of delta wing configuration.
 The most successful was the Mirage III supersonic fighter in its many variants, which were widely produced both by Dassault and by other companies.
 Some Mirage variants were given different names.
The Dassault LOGIDUC -sometimes spelled Logiduc in French and LogiDuc in English- ("Logique de Développement d'UCAV", French for "Unmanned Combat Aerial Vehicle development solution") was an autonomous industrial program launched in 1999 by the French aircraft manufacturer Dassault Aviation in view to develop its UAV design capacities.
 This French programme eventually led to the creation of the Dassault-Sagem Tactical UAV company and to the European "combat drone" project nEUROn.
Project ROSE (Retrofit Of Strike Element), was a program initiated by the Pakistan Air Force (PAF) for the upgrades of the military avionics and electronics system of its aging Dassault Aviation– built Mirage fighter jets.
 The program focused on modernization of military avionics and on-board computer system of Mirage IIIE and the Mirage V supplied by French SAGEM and the Italian SELEX consortiums, as part of the program.
The Dassault Mirage III (] ) is a family of single-seat, single-engine, fighter aircraft developed and manufactured by French aircraft company Dassault Aviation.
 It holds the distinction of being the first Western European combat aircraft to exceed Mach 2 in horizontal flight.
The Dassault Mercure was a twin-engined narrow-body jet-powered airliner developed and manufactured by French aircraft firm Dassault Aviation.
 According to Dassault, it was the first large-scale European cooperative civil aeronautics programme.
 The Mercure 100 holds the distinction of being the first commercial airliner to be operated by an entirely female crew.
The Sukhoi Su-57 (Russian: Сухой Су-57 ) is the designation intended for a stealth, single-seat, twin-engine jet multirole fighter aircraft designed for air superiority and attack operations.
 The aircraft is the product of the PAK FA (Russian: ПАК ФА , Russian: Перспективный авиационный комплекс фронтовой авиации , "Perspektivny Aviatsionny Kompleks Frontovoy Aviatsii", literally "Prospective Airborne Complex of Frontline Aviation"), a fifth-generation fighter programme of the Russian Air Force.
 Sukhoi's internal name for the aircraft is T-50.
 The Su-57 will be the first aircraft in Russian military service to use stealth technology.
 The fighter is planned to have supercruise, stealth, supermaneuverability and advanced avionics to overcome the prior generation fighter aircraft as well as ground and maritime defences.
The Dassault Mystère/Falcon 10 is an early corporate jet aircraft developed by French aircraft manufacturer Dassault Aviation.
 Despite its numbering sequence it was actually developed after the Falcon 20, and although it is sometimes considered as a scaled-down version of that aircraft, it was totally redesigned with a non-circular fuselage, a new wing with slotted flaps, a split passenger door and many simplified circuits compared to the Falcon 20.
The Dassault Mirage 2000 is a French multirole, single-engine fourth-generation jet fighter manufactured by Dassault Aviation.
 It was designed in the late 1970s as a lightweight fighter to replace the Mirage III for the French Air Force ("Armée de l'Air").
 The Mirage 2000 evolved into a multirole aircraft with several variants developed, with sales to a number of nations.
 It was later developed into the Mirage 2000N and 2000D strike variants, the improved Mirage 2000-5 and several export variants.
 Over 600 aircraft were built and it has been in service with nine nations.
The Atlas Cheetah is a South African fighter aircraft developed for the South African Air Force (SAAF), and currently operated by the Ecuadorian Air Force (FAE).
 It was developed as a major upgrade of the Dassault Mirage III by the Atlas Aircraft Corporation (later Denel Aviation) in South Africa and is based on the IAI Kfir.
 Three different variants were created, 16 dual-seat Cheetah D, 16 single-seat Cheetah E and 38 single-seat Cheetah C.
 The Cheetah Es were retired in 1992, and the Cheetah Cs and Cheetah Ds in April 2008, being replaced by the Saab Gripen.
 A limited number are still operated in South Africa as flight test aircraft.
 One Cheetah R was built as a prototype but never entered service.
The Dassault Rafale (] , literally meaning "gust of wind", and "burst of fire" in a more military sense) is a French twin-engine, canard delta wing, multirole fighter aircraft designed and built by Dassault Aviation.
 Equipped with a wide range of weapons, the Rafale is intended to perform air supremacy, interdiction, aerial reconnaissance, ground support, in-depth strike, anti-ship strike and nuclear deterrence missions.
 The Rafale is referred to as an "omnirole" aircraft by Dassault.
