That was in 80s and it was Britishers with their Jags. It was a big mistake. We should have chosen Mirage production line.
Mig 29 were offered later and were actually a good option. But we didn't even opted that.
In 2004 around the UPA government was just afraid to go for direct purchase route. And then Gripen was also on offer so I don't think Mirage was the best option later.
Not true. I don't think you're aware of the details.
The Jaguar was a DPSA for the IAF, a strike jet. It was acquired in the late 1970s and HAL had already started manufacturing them when the IAF bought Mirage-2000s in the mid 1980s to counter the PAF acquisition of the F-16A. The Mirage-2000 was the ONLY other FBW equipped fighter in the world apart from the F-16 (and given that the F-18 wasn't an option) and considered the most modern available to the IAF.
The original plan was to buy 40 Mirages off the shelf and then opt for license manufacture of 100 Mirage-2000s in India at HAL. That was a part of the options clause for the original contract of the Mirage-2000s itself.
But then USSR came and offered the RAM-K (later called the MiG-29) soon after the Mirage-2000s were bought. The MiG-29 had been a super secret program of theirs and had only been offered to Warsaw Pact countries. IAF officers evaluated it, loved it's incredible T/W ratio and performance and suggested to the GoI and MoD to acquire them.
Soon after, there were 2 types of air superiority fighters in the IAF, the Mirage-2000 and the MiG-29. Thanks to the MiG-29 coming into the mix, the options clause for the Mirage-2000 was never converted since there was confusion as to whether to manufacture the costlier Mirage-2000 in India or the cheaper MiG-29. Later on, in the 1990s, India's economy all but collapsed and all talk of the license manufacture dissipated. The serviceability headaches of the MiG-29 meant that the IAF didn't want any more of them beyond the 75 odd that it bought from the USSR.
Later on, the Russians offered the Su-27UB and it was evaluated by the IAF and eventually that led to the Su-30MKI program in the late 1990s to early 2000s.
