Check out whether its Mig-21 Bison or Mig -21 BIS
Russia, did their first test flight on October 6th, 1998. Trials of the medium-range Vympel R-73RDM2 and the Beyond Visual Range (BVR) Vympel R-77/RVV-AEE air-to-air missiles were conducted in February 1999. The formidable combination of the Phazatron Kopyo (Spear) light weight multi-mode radar with that of the Missiles proved a success, the subsonic target drone aircraft being destroyed by a R-77 fired from 6km away. In all the two prototypes were believed to have done nearly 200 test flights.
CO, Wg Cdr Dhir emphasized the ‘new’ features of the aircraft, including its ability to use BVR missiles like the R-77 and the usage of Standoff Weapons like the KAB 500, incidentally both of which were displayed on the Bison’s Weapon stations to the filming team (or for any media team) for the first time. The CO was all praise for the improved visibility of the new aircraft and the much simpler workload on the pilot due to the improved avionics.
Another significant upgrade to the aircraft is the new Helmet Mounted Sighting System, which enables the pilot to launch an Air to Air Missile at off bore angles, simply by turning his head towards the target.
