And with the F35 (that is going to evolve) the case for the Tempest is really to support UK’s aerospace industry & influence not much so to bring a new capability (or marginaly).

The situation is quite different for the countries that are not part of the F35 program, there is more urgency for them to move forward…Not only to support their industry but to remain relevant as an air force.

It seems to me that UK are making a bet that with initial funding & vast PR communication on the project it will gain enough momentum to convince partners to join the program and keep moving forward. They have to make the “tempest program” as credible as possible to create the necessary confidence to invite other nations willing to join.

Even if there is a genuine political will for the UK to demonstrate that they remain a tier 1 nation in military aircrfat design after the Brexit, without one or two major partners joining, some important adjustments will have to be made.

I also hope this is not the final design, too close to other conventional 5th gen designs and somewhat not up to date compared to NG/LM/Dassault/Boeing 6th gen proposals.

There was indeed quite some dead time between agressive maneuvres to regain energy. Other 4th gen jet can perform many more maneuvres in the same time frame. Video editing only shows the most dramatic moments. F35 high wing loading means that in an agressive maneuvre it reaches high AoA very quickly bleeding a lot of energy. F35 powerful engine and good FCS somewhat compensate that but there is no miracle in the end.

Just some thought from a neutral (as regard SU-57 vs F22) observer.

I think SU-57 design is brillant and looks very capable to me, it should match or exceeds the F22 in aerodynamics and perhaps kinetics with the new engines.

However I am not completely convinced by SU-57 stealth. The overall design is brillant but the manufacturing looks dated compared to F22 and F35 (riveting/apparent metal, canopy etc etc).

It seems to me that the SU-57 is some kind of a “budget 5th gen fighter” with some key attributes but without overinvesting in stealth or sensors. A more cost efficient approach than the west.

Like a Dacia Duster which is a lot of a car for the price in its own category to attempt a comparison.

I am sorry but this is not the state of affair. I am clearly giving some hard hints about what’s going on here and I have reported here and on SPF some more materials. Lullabies whispered into some Parisian cabinets won’t change a single thing. Let’s hope that someone with at least a dregree in accountancy has an eye on what France spend into that.
France would have had a chance if an entire industry won’t have turned its back to the modernity of aerial combat a decade and a half ago. EoA

I still believe you have not been following this process closely enough and that your are arguing for the sake of arguing which is quite boring. That has nothing to do with imaginary French Cabinet but what is published in the Belgium press right now (today). No need to rely on French sources.

It is pointless to give instances of radar as nor you nor me have the actual figures, this type of discussion will lead nowhere. I am just putting into perspective the output argument, not dismissing it.

The current process has been tweaked by the Flemish side to favor the F35 (especially the curent Belgium Mindef), this has been the assement made by France to propose a strategical partnership instead of sticking to the so called “official process” and this assessment is shared by many in the Waloon side of Belgium. That’s why the rafale proposal will be officialy considered as well as extending F16 remaining service life…At least that’s the position of the Waloons which is not agreed by the Flemish.

The current process is far from being consensual even within Belgium. It is far from being neutral and behind this competition there is a strong fight between the Flemish and the Waloons. The Flemish want to be close to the Netherlands > F35 and the Waloons want to be close to the French > rafale. Each side try to play their card…The Flemish card was the bidding process as they have one of their own as Mindef but after legal investigation the waloons side said French offer can be considered.
