I'm guessing the whole discussions with the MOD and IA will have to start all over again if TATA wants to go with Make-2 and not Make-1. Make-1 discussions have already eaten up so much time, and there's no guarantee that Make-2 will be any faster, which is why IA seems to be reluctant. Probably the MOD sees the opportunity to save the government some money which is why they are entertaining TATA's Make-2 proposal, whereas IA sees this attempt as further delaying an already delayed project and thereby lessening their warfighting capability. Indian DPPs are such that L1s were/are usually given preference. Buy Indian might just become the norm but the lowest bidder thing will be difficult to root out. TATA knows that being the L1 bidder will give them the upper hand so they go with Make-2 and bank on the politicians' practice of going for the lowest price weapon system, as the final okay will be that of the government's. Whereas the MOD knows how defence deals go in the country, look at the Rafale mess. "Why this much money is being wasted, when something can be brought for cheap?" is literally the first thing they want to avoid for such big deals. The "kitna deti hai" attitude biomagnifies down even to our political class. We have to stop this L1 business and provide for efficient logistics for vendors opting for either Make-2 or Make-1 and then opt for the best and not the cheapest product. After all, we are not haggling for aloos and gobis down in the market; this is the defence of the nation we are talking about.
