Wouldn't expect anything else from Mr Karnad who has been anti Rafale from the start.
The deal is still going ahead, there is no viable option the one there was (letting the EFT back into the race) has been flatly ruled out by the Defence Minister (God knows why). Buying more Su-30 is not going to boost the IAF rather be a drain on it for years to come.
It's interesting how people are calling the Su-30 the "economical" alternative to the Rafale when the Rafale would have around 1/3rd the life cycle cost, will be more available than the MKI fleet and costs about half the MKI to fly per hour!
Have no doubts, if the IAF are made to go for more MKIs the fleet will be worse off for it. There is a reason the IAF (the professionals) are pushing so hard for the Rafale, why don't all the armchair generals stop and ponder that for a moment?
It hasn't, that is a BLATANT LIE. The deal is worth $15-16 BN today, about a 25% increase from the cost quoted some 4-5 years ago, taking into account inflation and the rupees decline since then this is pretty reasonable.
