That's not how you create a MIC.
It's exactly how an MIC is created without diluting the force's preparedness.
I told you already, ATAGS still isn't fit for use in combat. What's the point of buying something that doesn't work for the sole purpose of just blindly supporting the industry?
In order to support the industry, if something doesn't work very well, then you only need to buy enough to help push the R&D process. So the deal for 150 ATAGS will very likely go through as long as it fulfills even some of the most crucial QRs. But there's no need to buy 1600 prototypes, it will just make some shareholders richer, it doesn't help the company become more capable, and will make the IA considerably weaker at the same time. So 150 ATAGS, 40 LCA Mk1s, 124 Arjun Mk1 followed by 118 Arjun Mk1A, and so on. So, if ATAGS still doesn't meet QRs even after the first 150 are delivered, they will make an Mk1A and deliver another 150, in the meantime they will have to use the lessons learned to make an Mk2 or a whole new gun. Like Arjun Mk2, which is basically a new tank.
LCA, Arjun and ATAGS have suffered because in all three, DRDO created their own QRs instead of just giving the forces what they want. For example, IA wanted to cancel the Arjun in the early 90s and start a new tank program suitable for our terrain. But DRDO was desperate to make a NATO standard tank for showing off, a tank completely unsuitable for our operational environment. LCA was supposed to be a simple aircraft without FBW, but DRDO added 10 years to it by wanting to create their FBW. It was also supposed to have a simple radar that existed in the 80s, not the more modern stuff that went into M2000-5 and F-16 B50.
ATAGS is similarly over-spec'd with stuff the IA never asked for. For example, IA never asked for a 25 liter chamber or more range than 40-42Km. In the Himalayas, the range will increase to 50+Km anyway, it was more than enough. But with a bigger chamber, it increased weight, the same with the electric drive, all weight increasing measures, which resulted in an overweight gun. An overweight gun means a bigger, heavier truck, and that means it cannot use many bridges in the mountains. And if it cannot use bridges, it means it can't be taken to the battlefield.
The IA simply goes by common sense. The IA doesn't care who owns the IP as long as the technology is fully usable up to spec and is supported within India. 'Cause IP laws go to sh!t when war comes along. India has rules where we can ignore IP during national emergencies. The IP holder will get some royalty money. But civilians go by emotions, and the industry preys on that via the media.
And unlike Arjun and LCA, ATAGS isn't even an official program, it's just a hobby project DRDO took up in parallel to IA's towed gun tender. And then, a successful tender was cancelled in favour of a gun that's still years away from attaining credibility. ATAGS currently doesn't even meet DRDO's own internal SQRs, never mind the army's PSQR for an inferior gun which was created for the tender which ATHOS won. If that weight doesn't come down to usable levels, then it's going the Arjun way.
