So, 200kg for both engines, and a structure that needs to support those 1.5 tons of increased thrust.
Which makes the aircraft overall much heavier. ~70cm longer is still quite significant. Plus the wing area means worse wing loading at high G which also needs heavier structure to hold everything.
Yes, but it’s impossible for the EFT to have 80+% mass of composite. You are most likely referring to surface area, in which case you need to use the same metric for the rafale. This would be 75% of the area of the rafale being composites. This is much more in line with the EFT
It’s pretty simple, Eurofighter is carrying the weight of being the sexiest top tier aircraft + the sheer mass of all the nerfs they needed to hit it with to let everyone else win sometimes.
Low key it makes sense that the prototypes would be heavier than the production variant as the prototypes would have to test a lot of various subsystems and weapons and such that wouldn’t be on the final product
All I will say is that the empty weight listed in certain documents includes things that the empty weight in game does not include. And I strongly suspect that if you properly account for those factors, you will find out that the empty mass in the your document actually shows the aircraft to be too heavy in game.
