Nonsense article, since when does HAL produce tires or LDP's? IAF did not complaint about engines last year (Ajay Shukla did) but some years ago, which resulted in the development of the Type 30 engine, that is now in production for the next batch of Pak Fa and FGFA prototypes. And that the demand of a new engine costs extra, should be logical or? UAE must pay extra if they want higher thrust engines on Rafale, Boeing offered us EPE engines for F18 SHs, if we pay extra, Kuwait paid extra for higher thrust engines in their Hornets..., nothing unusual.
We must get rid of the notion that we are an equal partner in the development of the fighter, we are not! Not because the Russians treat us bad, but because we lack the know how to contribute more! That's why crying foul everytime the Russians play things in their favour, because we are the weak partner is silly and wasted time, while we have to focus on improving our capabilities to contibute more or to change things in our favour.
We still don't know the details of the contract, but IF we compromised on a single seater Pak Fa / FGFA at first to keep costs in check, imo we must insist on the Russians buying their fighters with avionics made by HAL or Samtel too, to have one common layout that reduces costs. We have certain areas where we have the capability like avionics and it is in our interest to get the Russians to buy more of our stuff too!
