In 1999 when the Kargil conflict broke out, the Mirage 2000 performed remarkably well during the whole conflict in the high Himalayas, even though the Mirages supplied to India had limited air interdiction capability and had to be heavily modified to drop laser-guided bombs as well as conventional unguided bombs.
Two Mirage squadrons flew a total of 515 sorties, and in 240 strike missions dropped 55,000 kg (120,000 lb) of ordnance.
Easy maintenance and a very high sortie rate made the Mirage 2000 one of the most efficient fighters of the IAF in the conflict.
There are reports that the IAF qualified Soviet-designed missiles with the Mirage 2000, such as the R-27 (NATO AA-10 Alamo) AAM.
In July 2011, India approved an $3 billion upgrade to its entire Mirage 2000 fleet and for over 400 MICA missiles.
One of the two seat trainer versions crashed on 25 February 2012, another two seat version crashed on 5 March 2012.
