The contract that emerged from the 2007 bid process, in the end, had to be scrapped — according to the CAG report — because the financial bid did not take into account the man-hours required for production at Hindustan Aeronautics Limited, and because Dassault was chary of adding a performance guarantee for HAL-built aircraft to the agreement. This opened the door for another contract, such as announced by the prime minister on his 2015 trip to France. But by then EADS had offered a 20 per cent discount on the Eurofighter, and it is not clear why that unsolicited offer was ignored when deciding to buy 36 flyaway aircraft from Rafale — and not even used as a bargaining chip. The CAG report does not go into this, or into the process involved in the second contract.
The price comparisons themselves are not entirely meaningful, given that the defence ministry has insisted that the actual numbers be redacted. However, some of the numbers have been reported in The Hindu newspaper. The main saving in the second deal comes from the “India-specific enhancements” put in by Dassault to meet the original bid requirements. These saved just over 17 per cent, according to CAG, or almost 240 million euros going by The Hindu report. This is the major contributor to the total saving of 2.8 per cent, according to CAG, which works out to 223 million euros using The Hindu's numbers. However, this saving cannot be seen as entirely credible for two reasons. First, the cost of the enhancement is amortised in CAG’s calculations over 36 aircraft for both contracts, whereas there were 126 aircraft in the original bid. Second, dissenters in the original negotiating team have argued that the enhancement cost had not yet been the subject of negotiations and was inflated, so the 17 per cent “saving” is against Dassault’s first offer and not the final agreement.
