What makes you think that such extensive usage of RAS is not seen in TFX or J-20A. I don't believe Chinese has no such extensive materials breakthrough and usage.
You're misunderstanding. All new 5gen makers like Turkey, China, India, S.Korea are using their version of RAS & perhaps RAM too.
But USA being leader is ahead in continious R&D of materials.
Metal cutting happened in 2022. 3 years over, another 4 years = 7 years to make prototype.
EOTS for AMCA

If u look at history of Mk2 metal cutting.. it ll also extend and repeat for many years.
With time things should improve. Our machining tools will decide rate of production & that will decide our war potential.
Rest is up to makers.
Not really an 'EOTS' actually.
Came across some docs later and it seems I was right, there's no laser emitter or laser spot detector in this system. Just 2 Day cameras & 1 IR camera. It's just an EO/IR sensor. Will ask the source if okay to post publicly.
It would explain why AMCA models are always shown with external LDP. It's possible we may implement full EOTS capability only in AMCA Mk-2. Some reputed watchers say DAS-HD/DB (our EODAS equivalent) would also be put off till Mk-2. Which means Mk-1 will have a 'regular' MAWS.
It's for ghatak ucav.
There is no such thing called amca mk2 at this moment, these all systems will be present in mk1 version.
Multiple applications will be there.
You need a proper EOTS eventually. Otherwise you'll always need an externally carried LDP for strike missions. That defeats all aspect stealth, so won't be acceptable in long term.
But this sensor doesn’t have full EOTS functonality. So that means it will come later.
Mk2 is just the version with next-gen engine, where there is a possibility of the plane needing a degree of redesign to accommodate the new engine (who's specs & dimensions are as of yet unknown).
Several techs are being put off till that config emerges so as to not delay the Mk1 program with proven engine.
AMCA Mk1 will have over 90% commonality in avionics with Tejas Mk2.
ADA-001, ADA's 1st baby
It is very basic, they could have shown EOTS, IRST, DAS. But something is better than nothing.
Nose appears to be too long, or may be it is camera angle effect.
The engines are exposed a lot. The rudder's trailing edge could have been diamond or cranked-arrow/lambda shaped; The stab/elevator could be moved aft.
The flaps & aelerons actuator bumps need to be more flat & blended.
Inbuilt ladder not required, will increase RCS.
Perhaps a CCM can fit in SWB.
Regarding long Nose as you said, Nose was shorten in TEDBF and MWF after aerodynamic improvements. Before we get batter knowledge in aerodynamic optimization, AMCS design was almost freeze and scientist did not want to go to drawing board once again to save time. Was that the reason? My wild guess.
Well, that's making a jet from outside 1st towards inside.
Some ADA guys might have said - let's make it like YF-23, some said - no keep it like YF-22.
But when AMCA was initiated in 2010, then all these detailed process, CAD, CFD, etc would have completed by now in 15 years.
Anyways, keeping the internal process aside, the citizens think that metal cutting happened in 2022, so the prototype will roll out say in 2027. So are we on that time-frame track or not?
Inspite of long history of missing dead line, if somebody expects it to come in time than he is very optimistic.
Do not trust GE. Safran is an old partner in Chopper engine while Rolls Royce has a very good engine of their own (EJ 200) which can be battered to Make 75 KN/110-125 KN engine.
dunno why we are going with GE-414 and price negotiating engine deal now since originally GE was lowest bidder for tejas mk2 contest but IAF wanted ej-200 since its more modern plus lighter and thrust can be increased to another 20%! it was so damn futuristic almost 4.5 generation jet engine and whole tejas mk2 fiasco could be avoided by replacing the existing ge404 in tejas mk1
Air Force says DRDO stalling Tejas fighter engine

So basically they have hung Rafale's OSF suite upside down
The minimum apertures i can think of are 3 things - WFoV IR, NFoV IR, LD. Beyond that is day time TV cam & other sensors for each smaller bands.
For example if we look at Ka-52's sensor turret, we see at least 10 of them.
But obviously we can't put all of them in EOTS.
DRDO working on domestic LD-IR pod, so what they could do as work-around is straighten up the pod & put it in nose of jet.
So basically they have hung Rafale's OSF suite upside down
Pretty much, yeah.
In every industrial domain, even normal things can appear as big deal to outsiders or other domain professionals.
Different gen jets have separate technical approaches including airframe design & aerodynamics. Newer gen has more considerations.
We're not in era of drawing board but deep into era of CAD S/w, robotics & other automation since our IT boom in 1990s. If our DoD couldn't take advantage in last 25 years & still can't take advantage then that's unacceptable & ridiculous. The basic AI on cellphones can do lots of things with CAD quickly. And when our ISRO is doing so good then we can't complain about machining tools, wind tunnel & other testing, The ultimate result matters in stipulated time. The designers, makers must requests for funds & facilities on time & the govt. must provide funds, colaborations, etc on time.
BTW, YF-22 was redesigned in mid 1980s in just 3 months using that era's primitive computing & CAD.
After 40 years we should be able to do that with today's computing.
Otherwise a court of enquiry needs to be setup bcoz the civillian sectors will get ahead & start laughing on our DoD & GoI/MoD.

It's funny how MoD can make the media run in circles. As soon as engine dependency and it's effect became the obvious talking point, this private industry assembly of Jets like LCA mk1A>Mk2>AMCA was floated and like stupid trouts the defence circles gobbled it up. Bottom line still is all these programs are mutilated without an active evolving engine program. There needs to be an adequate pragmatic engine and off shoot programs to develop other uprating/derating applications for other platforms; and a sustainable new product development ecosystem.
