The Mirage was Matra-capable but these LGBs were not available because the IAF didn't have them. They purchased Paveway after the war started, then they realized that the Flipkart delivery boi had given the wrong parts so they had to take Israel's help to integrate it into the Mirage. Till then, they were sitting on vintage bombs. They had to use scrap to make the aircraft capable of delivering the bomb, because the IAF, in their words, had "never wargamed" a scenario where they'd have to drop LGBs at a high altitude despite knowing that Kashmir was a permanent flashpoint for a future conflict. So they didn't acquire that capability. "By 12th June, IAF personnel had ironed out most of the faults". The hardpoints for the LGBs were added 2 months after the war had started. They were showing all this bravery while our relatives were coming back in body bags. If, in a country like India, surrounded by mountains on both sides of the border, the IAF had never wargamed for the obvious scenario of high altitude precision strikes, one needs to invite the IAF to a high level committee and ask what scenario did the IAF wargame. What did they think those expensive planes were given to them for? joy rides?
