The Mirage F.1 replaced the familiar delta wing of the Mirage with a swept wing, set at shoulder height and fitted with flaps and slats. This was combined with a low-set slab tailplane. The F.1 did not achieve the enormous sales of the Mirage III, but was nevertheless sold to France, Ecuador, Greece, Iraq, Libya, Marocco, Quatar, Jordania, South-Africa, and Spain. A more advanced version, the F.1E with a M53 engine, lost the NATO fighter competition to the F-16. The Mirage 2000 has replaced the F1 on the production lines, but the Mirage F1 will continue in service for some time.
