Mirage III Blue Flash

I know that with the Blue Flash Programs I, II and III, Pakistan purchased:

Blue Flash I

18 – Mirage IIIEP (Serials 67-101/118)
3 – Mirage IIIDP (67-301/303)
3 – Mirage IIIRP (67-201/203)

Blue Flash II

2 – Mirage IIIDP (304-305)

Blue Flash III

10 Mirage IIIRP (204-213)

Just talking Mirage III right now, because I know that Mirage V’s were in some of these contracts :eek:, was there anything special about these aircraft that they put them under a special contract name or were they just like every other EP, DP and RP?
