Avionics: One transponder and a 16-item vocal warning system. Also has an automatic flight control system, an angle of attack indicator, a radio altimeter, a navigation and attack system, a rangefinder and a bullet shaped antennae above each pylon associated with missile guidance. The stub-shaped nose has an in-built laser guidance system for accurate bombing.

Comments: The MiG-27ML forms 7operational squadrons and is also part of TACDE (Tactics and Air Combat Development Establishment). An upgrade program, reportedly similar to the MiG-21 upgrade, is underway and will keep the MiG-27 viable well into the first quarter of the 21st century.

The upgrade is being undertaken by HAL Ozhar Division, the Defence Avionics Research Establishment [DARE] and CEMILAC/DGAQA. The first aircraft to be upgraded is TS-640 which was recieved by Nasik in May 2002. The aircraft was upgraded and first flown by HAL on 25th March 2004 and has been given to the ASTE in April 2004.

The upgrade will oversee the integration of the following technologies and components into the aircraft:-

» VRS Mission Computer
» Laser Designator Pod and New Weapons
» Multi Function Display Unit in the cockpit [MFD665]
» Radar Warning Reciever with Display Unit in Cockpit
» Head Up Display [HUD] with Up Front Control Panel [UFCP]
» Air to Air Refuelling Probe
» Upgraded Radio / Electronic Warfare System
» Laser Ranging and Marked Target Seeker [LRMTS]
» VOR/ILS System
» Solid State Flight Data Recorder [SSFDR]
» Chaff/Flare counter measure Dispensing system [CMDS]
