The Dassault Mirage 2000-5 and its derivatives are the result of an initially private venture by Dassault Aviation, aimed at providing Mirage 2000 interceptor aircraft with improved capabilities. This new slew of upgrades was centred around the Thomson-CSF RDY radar, an upgraded human-machine interface, the integration of MICA missiles (radar and infrared) and the ICMS Mk.II self-defence system for the export variants.

Development In the latter half of the 1980s, Mirage 2000 foreign sales fell, having failed in multiple fighter procurement competitions; the airframe capabilities were deemed lacking compared to more modern American counterparts. By February 1989, the first F-16A–to–ADF (air defence fighter) conversion was completed, enabling the already versatile aircraft to carry a maximum of 6 BVR missiles (first AIM-7 Sparrows, then AIM-120s), upgrading the AN/APG-66 radar to allow look down/shoot down capabilities; enhanced smaller RCS target detection and the addition of CW (continuous wave) illuminator for the Sparrow missile. This was an improvement compared to the 2 BVR missiles that the Mirage 2000C could carry at the time. This development prompted Dassault, in April 1989, to announce a private venture, aimed to rival the ever-growing American presence in the low-cost fighter market: the Mirage 2000-5. It was decided that the foundation for this upgrade were to be the Thomson-CSF RDY radar, the Matra MICA air intercept missile and a cockpit modernized with technologies developed for the Rafale program. Each one of these elements was tested from 1988 onwards, and they all came together on 24 October 1990 when a Mirage 2000B flew as the first modernized 2000-5 variant. A single-seater flight followed on 27 April 1991, with the aircraft being a prototype conversion of CY1, wearing the tail number "01". The same aircraft would go on to continue its flight testing career, wearing tail numbers "02" and "'03", perhaps indicating progressive avionics upgrades.

Approval for production was given on 25 November 1993.

In July 1996, trials for the integration of the MICA EM active radar homing missile (then known only as MICA, since the MICA IR infrared missile would enter service later) were satisfactorily completed.

In December 1997, the UAE ordered 30 new Mirage 2000-9s along with upgrades for 33 existing aircraft. This variant, tailored to Abu Dhabi's needs, introduced true multi-role capability thanks to the RDY-2 radar, advanced strike options, and the ICMS Mk.II electronic warfare suite. The  billion deal was finalized in 1998, with the Black Shaheen missile chosen as its primary long-range weapon. Around the same period, Greece expanded its Mirage fleet: in 1999 it integrated the Exocet for maritime strike, and in 2000 signed for 15 new Mirage 2000-5 Mk.II and 10 upgrades, though deliveries were delayed by issues with the ICMS Mk.III system.

RDY radar Development of the RDY radar had started earlier, in 1984. The aim was to create a multi-mode, look down/shoot-down fire control radar that could operate in the X band (NATO I band) and provide multi-targeting capabilities. It is equipped with a mechanically steered slotted-plane array, with the advantages of very good ground clutter rejection and very small secondary lobes. It can ideally track up to 24 different targets, with a maximum of 8 contacts being able to be tracked in TWS (track-while-scan) mode. It was first tested in June 1987 aboard a Dassault Mystère 20, and underwent testing for its ground mapping modes on the southwest of the in 1989/1990 and in Mirage 2000s 04 and X7. The initial RDY variant was employed solely as an air intercept radar, lacking any air to ground ranging mode. It retained the ground mapping modes from RDI, since these were only used for navigation and not actual ground ordnance employment.

Performance for the original RDY variant was estimated to fall a bit short of the AN/APG-66V2: around for the former, compared to for the latter. These ranges were calculated on an 85% detection probability against a target with a radar cross-section. RDY's air-to-air performance can be attributed to the permanently optimized use, and selectable automatic control of three basic waveforms: high, medium and low pulse-repetition frequencies (HFR, MFR and BFR):

Very-long-range detection () is achieved through the use of search-speed waveform (HRF-RV). Long-range detection (), including very low flying targets (less than ), is achieved through the range search waveform (HFR-RD). Medium-range detection () is achieved through MFR waveform, including very low altitude (TBA). Considering the detection ranges and the MICA missile flight envelope, these engagements are generally long range.

Later RDY variants (RDY-2 and RDY-3) were developed for export and never used in French service. RDY-2, for example, offered a 15% increase in detection range for fighter-sized contacts, a synthetic-aperture radar mapping mode, air-to-sea functions and a terrain-following mode.

Cockpit and ergonomics The origins of the Mirage 2000-5s cockpit design philosophy can be traced as far back as 4 July 1986, when the Rafale A flight demonstrator took off for the first time. This innovative aircraft contained the first iteration of what would become the VTM (), a head-level display collimated to infinity that would allow the pilot to switch from BVR (beyond visual range) to WVR (within visual range) combat without the need to refocus their eyesight. Following the footsteps of American competition in the early to mid-1990s the Mirage 2000-5 was equipped with three multi-function displays: two VTLs () fmounted at each side of the front panel, and a VTB () positioned where the original Mirage 2000C VTB used to sit. The "Dash 5" designation refers to these four screens, plus the VTH (), the French term for the HUD. The overarching cockpit philosophy emphasizes reducing pilot workload through fully integrated HOTAS controls, a refined human–machine interface (HMI), and VTL-based digital menu structures, replacing the majority of conventional analogue gauges with multifunction display-driven data management.

Starting from the front panel, the VTH has a 15° × 20° field of view, and in its various modes it projects missile ranging information, aircraft status information (speed, heading and altitude) and navigation information, allowing the pilot to metaphorically keep their head out of the cockpit and increase situational awareness.

Going down further, the VTM's only purpose is to display the radar scope directly in front of the pilot and with infinite collimation, to allow an easier transition from BVR to WVR combat, without the need to refocus the eyes. Through HOTAS commands it's possible to change radar parameters such as number of scan lines, azimuth scan, antenna elevation and radar modes (ground mapping, terrain avoidance, etc.).

The VTLs are two coloured LCD displays, mounted on each side of the front panel. They replace the vast majority of analogue gauges and dials from the Mirage 2000C, displaying information about attack systems, navigation points and countermeasures. Due to the deletion of the radar warning receiver panel from the aircraft, threat warning and electronic warfare information are also displayed on a VTL page.

Finally, the VTB is used as a TACSIT (tactical situation) display, where all information for navigation and the tactical situation are combined and projected. Aerial targets, SAM engagements zones, RWR contacts, area boundaries, maps, routes and FAOR (fighter area of responsibility) limits are also displayed on the VTB. In tactical mode, the VTB's primary function is to enhance pilot situational awareness through datalinks such as Link16 or LU2. It allows the pilot to monitor a real-time view of the formation, sharing flight data (altitude, speed), remaining missiles, target assignments, and RWR status (who is illuminated and from where). Control of the network is managed either by the formation leader, or by a ground-based command and control station or an airborne early warning and control aircraft, which also handles IFF (identification friend or foe).

The side consoles are mostly dedicated to the control of radios, engine start-up and navigational aids (ILS, TACAN/VOR and INS navigation).

To allow easier control during air combat manoeuvring, various controls were moved to the HOTAS system.

The Mirage 2000-5 Mk.2 upgrade introduced higher-resolution, night-vision-compatible LCD displays, and replaced the legacy PCN () INS panel with a Thales TOTEM 3000 INS/GPS data entry and display unit. Another upgrade is the addition of a second V/UHF radio with frequency evasion and enhanced encoding, replacing the older UHF "Red" radio that was installed on the Mirage 2000C and -5F. All of these enhancements were enabled by the integration of the Rafale's MDPU.

Variants Mirage 2000-5F

Originally independent from Dassault's private venture, the Armée de l'Air eventually acquiesced, financing the conversion of 37 Mirage 2000C S-4 to the 2000-5F ("F" for "France") standard. Prototype conversions of aircraft Nos. 51 and 77 were done at Istres, with the first flight of the new standard achieved on 26 February 1997. Airframe No. 38 was transferred to Istres on 30 December 1997 to meet contractual obligations, but it wasn't transferred to CEAM (a test and experimentation unit) for pilot training until April 1998. Externally, the 2000-5F is identical to the Mirage 2000C, with two key differences: the radome pitot tube was removed, and a LAM () datalink antenna was added on the tail to enable mid-course updates with MICA missiles.

Mirage 2000-5F airframes were divided in two distinct production lots: Mirage 2000-5F-SF1: This is the initial variant that entered in service in 1999, and in a lot of ways remained unchanged . Initially it was equipped solely with 4 MICA EM missiles mounted on the fuselage and 2 R.550 Magic IIs on the outboard wing pylons, with the MICA IR entering service in 2000, slowly replacing the Magic IIs. The -5F variant differs from the ones promoted for export, notably by the exclusion of the superhet antenna on the tail, thus retaining the French self-defense equipment developed for the Mirage 2000C (Serval, Sabre and Spirale), although with slight modifications. Converted aircraft included Nos. 38, 39, 73 and 78. Mirage 2000-5F-SF2: Proposed upgraded variant for French use. It would've featured a GPS navigation system, a JTIDS-type datalink, integration of a helmet-mounted sight and some kind of long-distance identification tool; electro-optical or infrared based. It is unclear if these upgrades were ever fielded, although it's very probable that the GPS navigation and Link16 JTIDS were actually implemented in the Mirage 2000-9 and later variants.

On 6 June 2024, French President Emmanuel Macron announced the transfer of an unspecified number of Mirage 2000-5Fs from Escadron de Chasse 1/2 Cigognes to Ukraine, with pilot training already in progress. The first aircraft arrived on 6 February 2025, having undergone modifications prior to delivery, including the removal of the refuelling probe and the alleged integration of the SCALP-EG missile and AASM Hammer bombs. On 7 March 2025 the Ukrainian Air Force would announce with an Instagram post that the newly delivered platform participated in air defense activities, downing several Kh-101 cruise missiles and drones.

On 12 February 2025 the chief of staff of the French Air and Space Forces, Jérôme Bellanger reported that Mirage 2000-5Fs and Rafale fighter downed "nearly a dozen Shahed-type drones" during air patrolling missions over the Red Sea. These Mirages were most likely deployed from the French airbase in Djibouti.
