These are "ideal" dreams.
We will need to "compromise" with reality.
Right now gtre also has plans for 140kn engine in future, using tecg developed for amca's engined
But no plans for VCE.
Right now our jet engine tech has just reached early 4th gen in terms of materials.
Even in that we lack lots of infrastructure.
For example, we don't have a 20kton press to created the single peace core ring that goes in Kaveri or russian al31 we domestically produce.
So Kaveri uses imported components too.
Engineers dream 1st then think & talk seriously then start making. It is the actual real technical truth by simple maths.
The real reality is possibility of war, possibly multi-front.
Students go to foreign university for 4 year graduation or 2 year PG & after passing they make most of it.
But we're talking about next 15 years of industrial JV R&D by 2040. Babies born today will become high school teens, that's a long time.
Whatever you think we lack proves how long we've been sleeping & now we're begging ToT. So all those missing things have to be funded & facilitated, people hired, etc, some shortcuts, some imports to fast track, otherwise be ready to say bye bye to Arunachal Pradesh & keep dreaming to take back PoK. If regime change occurs in our nation anytime after 5 years then they might happily give away more territories in case of war rather than making self-reliant military & economy.
So as EU is working on their 6gen VCE, so we should learn it & make for ourselves. Otherwise it is like failing in foreign university for 15 years.
I said it earlier also that JV doesn't have to target only 1 engine type. But if a 200 KN+ class VCE is made then it can power AMCA also like F-35 & our 6gen.
The only thing 6th gen in chinese prototypes shown seems like more stealthy design( but lost basic fighter level manurablity) especially against vhf(lack of vertical surface)
And potential for lots of electrical power.
You started going in circle.
Our AMCA is also not fully 5gen projected yet in static models & infographics.
Do we expect foreign power to disclose everything upfront? Do we expect us to disclose our secrets?
Foreign platforms won't improve over time? You think their jets are cola cans?
Who wants to overconfidently underestimate others?
Eventually future versions of f35, j20 etc can be upgraded with everything 6th gen is envisioned to be except the things I mentioned above( design and electrical power).
Really? Then why are they making 6gen jets? After long discussions also you're forgetting everything.
So if your worried about tech, we can develop it with amca, and can bring it to similar standards tech wise.
It won't be able to do same role as those larger "so called 6th gen" doesn't mean it will be outdated In that battle field.
Like f16 and f15 are considered same gen, one is light-medium Ish fighter other is a heavy fighter( more range,endurance, payload, more electrical power, more powerful avionics)
I never said AMCA will be useless, it'll be a stepping stone, but it can never be 6gen, nor can any 5gen jet. They can be MLUed to 5.5gen but not be made 6gen due to airframe limits.
More weapons capacity, more electricity & redundancy leads to bigger jets.
So the question would be would be will we need a heavy command Jet with lots of electrical power in future or can be compensate for it with other systems?
Giving commands to UCAVs can be done with secured tablet, like "nuclear football", but nothing can compensate a critical platform like a proper combat jet. The high electrical power is for DEW.
Like France seems to be going for a relatively smaller jet for their 6th gen( bigger than rafale but somewhat smaller than flanker) due to their carrier requirement.
Every maker nation won't do things same way.
