The Dassault Mirage F1 is a French single-seat air-superiority fighter and attack aircraft designed and built by Dassault Aviation as a successor of the Mirage III family. The Mirage F1 entered service in the French Air Force in the early seventies. Powered by a single SNECMA Atar turbojet providing about 7 tonnes-force (69 kN; 15,000 lbf) of thrust, the F1 has been used as a light multipurpose fighter and has been exported to about a dozen nations. More than 700 F1s have been produced. Among the second generation European supersonic fighter (ie, among those built in the sixties and early seventies) the F1 was the most successful, most significantly because almost all of its users have used it in wars and regional conflicts.
Dassault designed the Mirage F1 as the successor to its Mirage III and Mirage 5 fighters. Unlike its predecessors, it has a swept wing mounted high on the fuselage, as well as a conventional tail surface. The first prototype, which was developed by Dassault using its own funds, made its maiden flight on 23 December 1966. The type was officially accepted by the French Air Force in May 1967, at which time three further prototypes were ordered. With the greater thrust of its afterburning SNECMA Atar 9K-50 turbojet, the F1 easily outclassed the Mirage III. Although it has a smaller wingspan than the Mirage III, the F1 nevertheless proved to be clearly superior to its predecessor. It can carry up to 40% more fuel, has a shorter take-off run, a superior range in lo-lo missions, and better maneuverability.
In order to comply with the French Air Force's requirement for an all-weather interceptor, the first production Mirage F1C was equipped with a Thomson-CSF Cyrano IV monopulse radar. The later Cyrano IV-1 version added a limited look-down capability. However Mirage F1 pilots reported that the radar can easily overheat, reducing its efficiency. The Mirage F1 entered French Air Force service in May 1973 when the first production version was delivered. Initially, the aircraft was armed with two internal 30 mm cannons, and two Matra R530 medium-range air-to-air missiles carried under the wings. It was replaced after 1979, when the improved Matra Super 530 F entered into service with the French Air Force. In 1977, the R550 Magic was released. The F1 has these missiles mounted on rails on the wingtips. Around the same time, the American AIM-9 Sidewinder became part of the Mirage F1's armament, after the Spanish and Hellenic Air Forces requested integration of the Sidewinder on their own Mirage F1CE and CG fighters. The 79 aircraft of the next production run were delivered during the period March 1977 to December 1983. These were of the Mirage F1C-200 version with a fixed refuelling probe, which required an extension of the fuselage by 7 cm. The Mirage F1 served as the main interceptor of the French Air Force until the Dassault Mirage 2000 entered service.
With 33 years of first-line service since 1975 within the Spanish Air Force and earning itself ever since the role of primary interceptor for Early Warning missions due to its great performance (reaching mach 2.2), the Mirage F1 is a seasoned but still perfectly capable and reliable veteran that has been updated to the newest available standards but is unavoidably coming closer to the end of his active duty lifespan, and will eventually be replaced by the Eurofighter Typhoon (C-16 in the Spanish Air Force code). The Mirage F1 is currently flown by the Ala 14 (14th Wing) based in Albacete, and has been flown in the past by the Ala 11 (11th Wing) based in Manises, Valencia and by the Ala 46 (46th Wing) based in Gando, Canary Islands.
The Wing operating the type now, Ala 14, is (as of February 2009) composed by 38 aircraft of the F1M model divided in Escuadrón 141 (141st Squadron) "Patanes" and Escuadrón 142 (142nd Squadron) "Tigres". Ala 14 reached 180,000 flight hours with the F1 model in late 2007, which gives an idea of the unit's familiarization with the Abuela ("Grandma"), as it is dubbed by its pilots. The features of the existing F1M's of the Ala 14 include intelligent 26" HUDs with integrated radar, HOTAS system, modernized Cyrano IVM radar for accurate ground-attack capability in four different modes, Night Vision Goggles compatibility, inertial navigator Sagem ULISS 47 and AIM-9 JULI Sidewinder compatibility among others. A total of 90 units of the Mirage F1's different versions have served with the Spanish Air Force over the years. These Mirage F1 have been deployed in Lithuania, during NATO Baltic Air Policing from July 2006 to November 2006, being scrambled twice to intercept undisclosed intruders.
On 20 January 2009 two Spanish F1s from the 14th Wing crashed near their base, in Spain's south-eastern province of Albacete, during a routine Spanish Air Force dogfight training mission, killing all three crew members. The wreckage of the two jets, including the remains of the aircrew, was found about 3 km (1.8 miles) apart. This accident has caused some sectors of the non-specialized media to broadcast allegedly misleading information about the Mirage F1's capabilities and claim for the substitution of the Mirage F1's based mostly on its age and in the existence of previous negotiations already initiated to sell the F1's to several foreign nations, ignoring the facts that the F1's will meet at 100% the NATO requirements for several more years and that collisions during close dogfighting exercises are relatively common and inconsistent with the aircraft's age, as indicated by experts, who have also expressed to be reluctant to jump to conclusions before the accident investigation's findings by the JIAAC are finished and released to the public.
