I think is the effect of bad business in the case of INS Vikramaditya........
Well, it may definitely piss the Russians off. But the Chinook hasn't won officially as of yet. It is still in discussion and will take time before a definite winner can be decided.
The Halo has the good advantage of previous infrastructure to maintain them and I simply cannot believe that the Chinook is cheaper than a Russian product. The Mi-26T is a modernized version of the old Mi-26 that most of my fellow Indians here are confusing with. As per what the Russians say, the Halos are quite heavily modernized with a crew of only 2 pilots needed to use the helicopter apart from the usual Load-master unlike the crew of 6 in the older ones that we have.
The Halo can lift much more payload than the Chinook and it has already been used in our military.
However, let's see how the Russians deal with this one.
I have a feeling that if Chinook wins this one, then the Light utility helicopter contract of 197 helos will go to the Russians for sure.
