Uncertainty is not the word where the AMCA engine is concerned - it doesn't exist and there is no firm go ahead on one. But I thought that the radar was not very uncertain - Mk1A nearing a production version (I imagine), MWF under development. If they can do those two, I guess they should be able to do one for AMCA.Hmmm.
I am saying this due to uncertainty on few things, like engine, AESA radar and many other electronics. And .......Ya! money.
Money... if GOI won't pay for the engine, Mk2 can be scrapped and that would save a load in development costs, wouldn't it?
