In the first phases of the project, the PAF acquired 33 former Australian Air Force's Mirage III fighters were upgraded and designated "ROSE I". The PAF then procured surplus Mirage 5F fighters in the late 1990s from the French Air Force in two batches. Around 20 fighters from the first batch were upgraded with new cockpits, navigation/attack suites, defensive aids systems and a forward-looking infrared (FLIR) sensor under the aircraft's nose/cockpit, being designated ROSE II. The cockpits included new MFDs, HUDs, HOTAS controls, radar altimeters and RWRs.
