Mirage 2000-5
The Mirage 2000-5 is a major advancement over previous variants and embodies a comprehensive electronic, sensor, and cockpit upgrade to expand its combat ability, while reducing pilot workload. The centrepiece of the Mirage 2000-5 overhaul is the Thomson-CSF RDY (radar Doppler multitarget) with look down/shoot down capability. The multifunction radar is capable of air-to-ground, air-to-air, and air-to-sea operations. In the air-to-ground mode, the RDY has navigation and attack functions that give it deep-strike and close-support capabilities. Capable of automatically locking onto multiple targets at first contact, the radar could detect flying targets travelling as low as 60 m (200 ft). The introduction of the radar allows the aircraft to use the MICA missile, up to six of which could be fired simultaneously at targets due to the advances within the radar. Despite the increase in offensive capability, pilot workload is compensated for by the introduction of a multidisplay glass cockpit, based on the development of the Rafale. The aircraft has the ICMS Mk2 countermeasures suit, which contains three radar detectors and an infrared sensor that are linked to active jammers and chaff/flare dispensers.^{[​24][​25][​26][​27]}

Improvements over the Mirage 2000C included the Thales TV/CT CLDP laser designator pod and the multimode RDY, which allows detection of up to 24 targets and the ability to simultaneously track eight threats while guiding four MICA missiles to different targets. Updates to defensive systems included the ICMS 2 countermeasures suite and the Samir DDM missile warning system. ICMS 2 incorporates a receiver and associated signal processing system in the nose for detecting hostile missile-command data links, and can be interfaced to a new programmable mission-planning and postmission analysis ground system. Avionics were also updated, using a new night vision-compatible glass cockpit layout borrowed from the Dassault Rafale, a dual-linked wide-angle head-up display, and HOTAS controls. The Mirage 2000-5 can also carry the oversized drop tanks developed for the Mirage 2000N, greatly extending its range.

Enhancements to offensive systems included a datalink for the targeting of MICA EM missiles, the addition of the Damocles forward-looking infrared(FLIR) targeting pod, and a newer, more stealthy Thales RDY-2 all-weather synthetic aperture radar with moving target indicator capability, which also grants the aircraft improved air-to-ground capability. The avionics were further updated with higher resolution color displays, an optional Topsight helmet-mounted display, and the addition of the modular data-processing unit designed for the Rafale. A new Thales Totem 3000 inertial navigation system with ring laser gyroscope and GPS capability were added, providing much greater accuracy, higher reliability, and shorter alignment time than the older ULISS 52 navigation system it replaced. Other upgrades included the addition of an on-board oxygen generation system for the pilot and an ICMS 3 digital countermeasures suite.
