The Russians have realised that
A Twin Engined Su 57 is less Stealthy
So now they are going for something
Similar to F 35
Our AMCA will be delayed As Usual
This single engine jet is meant for export.
Also, the Su-57 is a very stealthy aircraft. You need to stop believing western media reports about it.
So we need something to take care of your personal Favorite the J 20
A J-20 competitor is needed from 2023 until 2030. This jet won't be ready and will likely not be competitive enough either.
In order to compete with the J-20, we need a large aircraft, something that's not constrained by size and power limitations like the Rafale. A larger aircraft will be able to keep up with the J-20 because it can accept bigger, bulkier electronics, but the Rafale needs technology to mature a lot before it can be used. It's the reason why even older tech radars like the Irbis on Su-35 can outrange the AESA radar on the Rafale. It's the same reason why desktops will always be more powerful than laptops. This new aircraft will suffer from the same problem as the Rafale.
The J-20 could already be flying with GaN, and the Rafale will match that only after 2027. By then, the Chinese may introduce a J-20D with even more advanced tech. So this will keep the Rafale behind the J-20 perpetually. Especially so when we consider the Rafale F3R is not competitive, as determined by the Swiss evals. The Chinese are progressing far too quickly for European tech to compete anymore.
Let's hope MWF and amca won't be derailed.
I doubt the Mk2 will, since it's merely a modified Mk1, but the risk with AMCA will always be there. Especially on the engine front.
