In response to interest expressed by the AdA in a reconnaissance model of the Mirage design, Dassault proceeded with the development of a pair of prototypes. On 31 October 1961, the first of these prototypes conducted its maiden flight; on 1 February 1963, it was followed by the first production-standard aircraft of the model. The AdA opted to obtain a total of 50 production Mirage IIIRs; the service later ordered a further 20 Mirage IIIRDs as well. Several export customers, most notably Switzerland, also chose to procure reconnaissance Mirages. The Mirage IIIR preceded the Mirage IIIE in operational introduction.
