Dassault Mirage F1
The Dassault Mirage F1 is a French fighter and attack aircraft designed and manufactured by Dassault Aviation. It was developed as a successor to the Mirage III family.
During the 1960s, Dassault commenced development of what would become the Mirage F1 as a private venture, alongside the larger Mirage F2. Work on the F1 eventually took precedence over the costlier F2, which was cancelled during the late 1960s. The French Air Force (Armée de l'Air) took interest in the fledgling fighter to meet its requirement for an all-weather interceptor aircraft. Accordingly, initial production units were equipped with the Thomson-CSF Cyrano IV monopulse radar. During the latter half of 1974, the Mirage F1 entered service in the French Air Force. Shortly thereafter, the type was deployed as the main interceptor of the French Air Force, a capacity which it continued to serve in until the arrival of the Mirage 2000. It later transitioned to an aerial reconnaissance role. In July 2014, the last French Mirage F1s were retired from service.
Powered by a single SNECMA Atar 9K-50 turbojet engine, which provided about 7 tonnes-force (69 kN; 15,000 lbf) of thrust, and armed with an array of French and American-sourced armaments, the Mirage F1 has been operated as a light multipurpose fighter and has been exported to around a dozen nations. The type has seen action in a large number of armed conflicts involving several of its operators, including the Western Sahara War, the Paquisha War, the Cenepa War, the Iran–Iraq War, the Gulf War, the South African Border War, the War in Afghanistan, the Chadian–Libyan conflict, the 2011 military intervention in Libya, and the Northern Mali conflict. Although sources differ, and no official record exists, somewhere in the region of 726 Mirage F1s of all variants and trainers were manufactured during its run between 1966 and 1992. It was succeeded in production by the Dassault Mirage 2000.
The Mirage F1 emerged from a series of design studies performed by French aircraft manufacturer Dassault Aviation. Having originally sought to develop a larger swept wing derivative of the Mirage III, which became the Mirage F2, to serve as a vertical take-off and landing (VTOL) propulsion testbed akin to the Dassault Mirage IIIV, however, it was soon recognized that the emerging design could function as the basis for a competent fighter as well. Both the Mirage F2 and a smaller derivative, referred to the Mirage F3, received substantial attention from both Dassault and the French Air Force, the latter being interested in its adoption as a long-range fighter bomber as a stopgap measure prior to the adoption of the envisioned Anglo-French Variable Geometry (AFVG) strike aircraft.
Parallel with the Mirage F3 study, which was intended to serve as an interceptor aircraft, Dassault decided to study a single-seat derivative which featured the all-French SNECMA Atar 9K-50 turbojet engine. As a result of the cancellation of two major projects, the company's design team found themselves with a decreased workload. Accordingly, in mid-1964, Dassault decided to commence design work on the smaller aircraft, subsequently designated as the Mirage F1, with the intention of producing a successor to its Mirage III and Mirage 5 fighters; This work was performed under a government contract in anticipation of a potential French Air Force specification for an all-weather interceptor to succeed its fleet of Mirage IIIC aircraft.
The Mirage F1 was of similar size to the delta-winged Mirage III and Mirage 5, and was powered by the same SNECMA Atar engine as had been used on the larger Dassault Mirage IV; however, unlike its predecessors, it shared the layout of a swept wing mounted high on the fuselage and a conventional tail surface as used by the F2. Although it has a smaller wingspan than the Mirage III, the Mirage F1 nevertheless proved to be superior to its predecessor, carrying more fuel while possessing a shorter take-off run and superior maneuverability.
On 23 December 1966, the first prototype conducted its maiden flight. The first flight had been delayed due to a funding shortage affecting the overall program. During its fourth flight, the prototype was recorded as having attained a top speed in excess of Mach 2. On 18 May 1967, the first prototype was lost in an accident at DGA Essais en vol, Istres; the crash had resulted from a loss of control after encountering flutter, killing its pilot. Despite this misfortune, during late 1966, the Mirage F1 programme was officially adopted by the French Air Force. Following a redesign period, on 20 March 1967, the second prototype performed its first flight.
On 26 May 1967, an order for three Mirage F1 prototypes was placed, while the larger and more expensive Mirage F2 was formally abandoned. These three pre-service aircraft, along with a static structural test airframe, soon joined the test programme. By late 1971, the construction of an initial batch of 85 production standard Mirage F1 had been authorised.
