And US 6th gen jet??? and i should say tempest will be 5.5 gen and Franco- German program will be 6th gen, in my opinion
That is the toppic of this thread and so no need to mention US fighter will be 6th gen.
No basis to say that Franco-German will be 6th gen and Tempest 5.5 gen.
UK has the best jet engine technology in the world on par with the US and it also has massive stealth experience as it had 25% workshare on the F-35. UK companies fabricate sections of the F-35 fuselage.
Franco-German fighter only has Rafale as it's legacy and the French engine tech is weaker than the UK for sure. 5.5 gen it will be and will be outclassed by even the Chinese 6th gen fighter which will be the next step after J-20.
In terms of capability for next gen fighters expect the following.
1. US ~ UK - Slight edge to US
2. China
3. Franco-German fighter.
