Comments: Progressively replacing the Mi-8 in IAF service. The Mi-17s were very active in providing CAS (Close Air Support) to Indian troops during the Kargil campaigns during 1999 at altitudes in excess of 15,000 feet. One helicopter and all its crew, from 152 HU, were lost when it was shot down by Pakistani stingers.
In May 2000, India and Russia signed a $170 million deal for 40 additional Mi-17 helicopters. These are of the Mi-17-1B variant, which have more powerful engines and enlarged side doors, allowing quicker disembarkation of personnel. The first four choppers were delivered on 19 October 2000 and the last batch will reach India in mid-2001. The helicopters will be fitted with sixteen Vikhr-V (AT-16) anti-tank guided missiles after all 40 helicopters have been delivered.
