My question would be on what bases this conclusion is made, since there is no finished product so far? Let them build MK1 first and provide some propper specs about it, then we can compare and get to conclusions.
Wrt responsibility... When the fighter turns out around 1t heavier than planned, or when the gears of N-LCA are designed too strong and heavy as needed it's ADAs responsibility, when radar and engine developments gets delayed or even failed and can't be finished according to the requirements that, it's DRDOs responsibility. The forces instead are responsible for wanting a fully capable and ready fighter, instead of improving and maturing it after induction into service.
So they all have their shares, but the main responsibility for all the delays clearly lies with ADA and DRDO!
Switching to AMCA is the worst thing we can make, because we learn nothing if we don't find the mistakes of LCA program and correct them. That is only possible if we finish the project and induct it into operational service and not by simply closing our eyes.
LCA was never important for India as a fighter, because it's just aimed to be the low end of the fleet. The importance comes by the fact that it was meant to be the base project of the aero industry and any further upgrade, design, R&D development in future should be based on it. Without finishing it, all this is not available and besides all the time and money we wasted, we would start at the begining again!
Btw, Aeronaut has no idea what he is talking about when he claims LCA would be outdated. When you look at the materials, techs and capabilities or the overall potential, it's more than close to Gripen level. LCA was developed with with a good growth potential in mind and still would have a good future, if it only would be inducted into service and de-linked from all the unnecessary stuff!
