India does not need 42 sqs and will not have enough pilots enough standoff weapons bases and logistics support to maintain 42 sqds.
This number cane from an era in the 1980S when air power was without force multipliers cyber warfare and asymmetrical warefare.
We need 32 sqd only but they need to be no junk in this ie
260 su30 mki including 120 super mki
80 rafales
80 mig29upg
50 mirage2000
120 tejas
By 2030
Then mark 2 tejas from 2030 alongside f35 lightening
We can't wait for Amca this is 20 years away we need f35 by 2030 in 3 sqs
We need 32 Sqd only ? Wrong.
Though we don't have enough Force multiplier as of now but if in future we get them even then we are forgetting that our enemies are getting them and still.maintaining their fleetsize.
Right now IAF is keeping it's airfleet availability pretty high due to shortage of fighter jets. That takes lot of money , If we had enough number of jets on ground we could have kept the availability rate low and do with the op budget we get. But during war time we can bring the availability rate high and benefit from the jets already available.
You are saying in a nation of 1.4 bn + we don't have pilots to fly the jet?
And there will always be a mix of outdated ones and advanced ones.
Mirage 2k and Mig 29 UPG we fly aren't the advanced breed of fighter jet today.
Even Sukhoi are outdated unless they gets an upgrade now and long range BVRs.
We have 5 Rafale with AESA and 2 updated Jags I guess. That's our modern airforce Tech edge
If we don't spend heavy on Airforce rest will be all useless.
