So allow me to rephrase it: given that my own country is still receiving the last batch of Typhoons and that we have still a quite capable attack line in the form of Tornado and AMX, I think that the decision not to accellerate F-35 acquisition in any way but at the contrary to wait until new capabilities would be added makes a lot of sense.
I understand however that other nations would be in a way greater haste to acquire bigger batches a.s.a.p. to replace planes with a way greater flight hours average.

I will also raise my doubt there.
There have been a significative signing off of legacy fighters in the moment F-35 has reached IOC or even before it?
Serious question there, maybe I have not just noticed it.
They are talking about putting an Aesa radar on F-16 so seems that they have not interrupted the updating work on it in prevision of the futurearrival of F-35.
Also on concurrency cost: obviously they would be significantly reduced on individual basis as soon as the production lot come closer to the FOC configuration i.e. the 3F but how many years they would stay in it without being upgraded?
Even you have said that they plan to substitute the actual FLIR and DASS systems between a few years, so they would kept the LRIP on 3F configuration or would modify them as well?
Certainly , in doing so such modifications would be listed as post-production and not concurrency cost but it will be more money the same.

Where did I compare it to the Su-57? Also, the LRIP-1 aircraft were pre-production models never intended for operational service AFAIK. I believe the AF-1 was used to test mission systems, while AF-2 was a flight sciences aircraft.

The “first serials” are instead fully developed planes, built in the same serial line that would be used for the normal production andare at the same standard of the full rateproducion.
Their function is to optimize the functionality of the serial line itself, not to further advance he project.
They call them in that way (instead than the western pre-serial or series zero) precisely to emphazise such aspect of total commonality and operativity and also because their construction is the only moment in which the Design Bureu and the production plant (that in their own organization model are two completely separate entities) have to work together.
So they will order them with a separate contract from both the ones of prototypes (that are awarded to the Design Bureau only) and the various batches of serially produced planes (that are awarded to the airplane Production Organization only i.e. in this case KnAAPO).

So it would not means that they would order just these two a.s.a. they are done they can award another one for the full scale production, obviously a batch a time as always.

There was this link where UAC said T-50 will face same utility as Su-27.
Meaning a two crew, Su-57IB version, etc.
But darn these delays..
Thanks

It’ the engine issue that is actually blocking everything there, until izd 30 is not ready no way to work on a 5/6th gen substitute for Su-30, Su-33 or Su-34.

no integrated EOTS like the F-35?

No, they already have it in the Su-34 i.e. their own dedicated light bomber.

@ haavarla
There were zippo factual evidence that ANYTHING could be launched from the Su-57 weapons bay until few weeks ago.
Still until the beginning the possibility to carry long range A2A missiles in the weapon bay was considered one of the main requisite of the whole program.
And understandably too as the tactical convenience of coupling VLO platform with long range missiles in order to ger rid of enemy AWACS is quite evident.

Yes, it’s not intended as a “stealth is an useless garbage” gig, just let’s compare the relative gain of a given innovation with the added costs (in any sense) of implementing it.

A certain level of RCS reduction can certainly to be achieved but probably in the sense of multi-band sensitivity that regarding absolute numbers.

@BlackArcher

Exactly what I was wondering..they produced the Rafale, which has to be one of the most beautiful designs of all time..and then the next gen fighter turns out to be so disappointing..Typhoon was quite a looker as well, but this Tempest looks downright ugly. The front fuselage seems similar to that of the J-20, another fugly fighter.

Still is one of the few so called gen 6th that almost has a remain of rudders, all other sketches (because there still NOTHING nowhere near to even a first flying prototype) feature tailless design, didn’t know if just for appearing substantially different from actual ones even at a first glance or because there is a requisite of get rid of them for increasing stealth.
Personally I am quite dubious it will work as i think that the effort to get to an acceptable tailless configuration would be much more challenging and would take much more time that the one needed to pass from GaAs to GaN AESA if not to even to get functioning Photonic Radars.
