A number of reconnaissance variants were built under the general designation of Mirage IIIR. These aircraft had a Mirage IIIE airframe; Mirage IIIC avionics; a camera nose and unsurprisingly no radar; and retained the twin DEFA cannon and external stores capability. The camera nose accommodated up to five OMERA cameras.
The AdA obtained 50 production Mirage IIIRs, not including two prototypes. The Mirage IIIR preceded the Mirage IIIE in operational introduction. The AdA also obtained 20 improved Mirage IIIRD reconnaissance variants, essentially a Mirage IIIR with an extra panoramic camera in the most forward nose position, and the Doppler radar and other avionics from the Mirage IIIE.
