Although the aircraft exterior has not changed in the 20 years, its interior has been transfigured completely. Besides the radar, the aircraft is fitted out with the optical guidance system allowing it to hit targets despite strong radio interference. MiG-29 is armed with six air-to-air missiles, four air-to-surface missiles, and missiles hitting through concrete 1.5m thick covers. The optical guidance system, including a laser distance-measuring instrument, rids the pilot of the need for pointing. The MiG-29 is unique because it "forgives" many pilot mistakes. It is the only one among light fighters where a pilot is not restricted in terms of firing.
