This is a idiotic comparison, People are looking at it in the terms of load carrying capacity, unfortunately for those who talk from that point of view is going to greatly disappointed just like Eurofighter and Boeing. Indian Air Force doesn't care if Eurofighter is faster by .2 Mach over Rafale, as long as they meet the minimum requirement. So Mi-26 carrying X loads more than Chinook doesn't really matter. I hope you remember, this was the same arguement made by Eurofighter and Boeing in case MMRCA. Mi-26 carrying such large loads comes at a cost, it cannot be used tactically. It becomes a Strategic helicopter, IAF will ask the question, does it need a strategic helicopter? Carrying one single BMP or 2/3 more is not going to change anything tactically, all the while they cannot put directly inside a firezone. If it is a hot zone, Mi 26 isnt going in, they are going to stay out of that zone. Its too slow and large to be used tactically.
IAF wants a tactical helicopter. The Chinook is going to win this. I am not even getting into the uptimes of Chinook and Mi26, it will put the latter to shame.
