Welcome to the era of development of latest Fighter jets, popularly known as 6th generation Fighters, the 5th gen hunter-killers.

There may not be ISO standard of complex product as a whole like combat aircraft, just like many household & commercial products like trains, trucks, cars, bikes, computers, networking devices, operating systems, applications. But the H/w & S/w components do have ISO standards, Patents, IPR (Intellectual Property Right) with numerous permutation, combination of final product/service. The basic objective remains same in every domain - compete & defeat rivals.
Hence, a leader country/company in any domain won't stop to try to maintain their dominance & will 'de-facto' dictate the characteristics & aspects of that domain's products.
Nobody is stopping anybody to do R&D & come at par with or overtake leader(s).
Any military product/service is also a business opportunity. Wars errupt suddenly & the outcome matters, not excuses & reasons - social, political, financial, etc.

From 1st to 6th gen & future, just like today it is difficult to consider some jets as 4th/5th gen due to overlaps caused by MLUs, same was the case since beginning b/w all previous gens & will be there till eternity. We can say there are primary & secondary features.

Following is a superficial comparison b/w 4th, 5th, 6th gen features. You can refine it further.

> Italy, Japan, UK have teamed up & publicly outlined GCAP (Global Combat Air Program)
> France, Germany, Spain have teamed up & publicly outlined their FCAS (Future Combat Air System)
> Russia is researching on PAKDP, also referred to as MiG-41
> USA is researching on NGAD & F/A-XX programs.
> China has shared a preliminary tail-less airframe with diamond shaped wings.
> Bhartiya Vayu Sena (Indian Air Force) has stated they have a roadmap for 6th gen jet, but have not showed any concept outline yet.

No matter how the 6th gen fighters will look, according to preliminary requirements outlined & the upgrades happening on F-22 & F-35, all parameters like size, volume, empty weight, gross weight, MTOW, fuel, longer range weapons, more EW capability, dry/wet thrust, more A/c range, cost, etc would be 30-60% more than present heavy jets like F-22, F-15, Su-57, Su-35, etc.

do not take me old fashion but I still prefer the F-18 in looks, well at 54 it is obvious I am old fashion, but I still prefer MiG-29 and F-14 in looks regardless of how advanced are these designs

I am also old-fashioned nostalgic kind of person, but in personal life. I don't spend money in overbudgeted things which i won't use.
I also like some older jets like F-14, MiG-29, Su-30 but technology evolution simply doesn't support their airframe, that's why a gen leap occurs.

this is my favorite MiG-29 variant, india bought it.

Of course technology advances, but beauty is nostalgic some times I was 15 when I saw a picture of MiG-29, new fighters might become beatiful but so far I only like F-22 and the new Tempest.

For those who may be curious, some info on the Anglo-Italian-Japanese GCAP 6G fighter project. Little info is published about this project but more may emerge as it approaches a go/no go decision in 2025. It is expected to be a very large fighter with a very long range. Main 6G features anticipated are:
  • sophisticated, secure datalinks that allow for the networking of sensors and weapons with friendly forces
  • helmets that display virtual, see-through cockpits for the pilots while monitoring their mental states to enable intervention when overtasked or unconscious
  • integrated AI that will assist the pilot in many tasks, including issuing instructions to multiple ‘loyal wingman’ style combat drones that can undertake high-risk missions
  • advanced adaptive cycle turbofan engines that can reconfigure mid-flight to optimize either performance or fuel-efficiency
  • Improved engine-cooling and gearbox-less electrical generators producing ten times more electricity to power sensors and perhaps eventually directed energy weapons

BAE Systems blurb from Farnborough air show in July:

With radar anticipated to deliver 10,000 times more data than current systems, I wonder what will be done with that data. The other thing I wonder about is if the fighter is very large with very long range, how can shorter -ranged 'loyal wingmen'(I presume) accompany it to its target area?

France would want to be in charge, so no, I don't think they can be successfully merged. However, it is possible that funding requirements could force some accommodation. There will be many systems common to both aircraft where development cost is being duplicated.

FCAS & GCAP look identical with cranked-arrow wing & V-tail, difference in wing position & V-tail angle.
Are there any tech comparison on these 2 differences, like long-arm canards of EF-2000 Vs close-coupled canards of Rafale?

Small correction, the GCAP model has been updated to use a new delta wing design over the cranked arrow during the Farnborough airshow, as seen in the image below.

As for now there is no real indication the 2 european 6th gen fighters will merge.
But the price of each will be so high... It is not impossible, once the prototyp phase closed, that such an attempt will be made.

For France I see a mix fleet of Rafale F5/F6 and 6th gen fighters. As the US with F16/F15 or F35/F22. That means a small 6th gen fleet. I think all the others will made the same choice because only some very high risk missions required over priced 6th gen fighters.
And the smaller the number of bird to produce, the higher the unit price is.
The R&D cost of the 2 6th gen "EU" fighters will be a burden. so....

It is now quite beautifull.
Before it was ugly. And as said by Marcel Dassault : "a beautifull plane fly well".

It is the EF2000 / Rafale history....
The budget issue, in GB and in France, may ease another approach.

I just see one : The FCAS will be adapt to carrier use. Thay may explain a more flat position of the tail for a more energical vertical authority.... If not they are now very similar.
But are those drawings real ? We may be surprised....

Americans say that V-tail has lower RCS. But its deflection like rudder produces both roll & yaw.
For pitch control also there will be vertical & horizontal components of effect of angled air flow.

Isn't the recent updated design a Tailless-Caret-LEVCON for FCAS? They seem to be going for tailless version.
