Does someone maybe have any good comparative photos/analisys of the differences between Su-27 and Su-35 mostly in fuselage shape - apparentely there are some. Wikipedia says the hump behind the canopy is lesser on 35 to shave off the mass, for the same reason it lacks airbrake, also the nose seem to be a bit thinner although it's hard to determine definatively by looking at photos under various angles. Im looking for some detailed comparison..

Over 700 Pages. :shock: It looks they go really into details of the Su-30 variants.

I can recommend this book. Its from 2017.

https://www.amazon.com/Sukhoi-27-Russia ... 0764356372

The German Author Andy Gröning has also written a book about the Mig-29. And seems to have a good relationship to Russian military aviation industry.

The book has also a chapter about the Su-35. Some details.

Wingspan has increased from 14.7 to 15.3 meter. The cell has a higher proportion of titanium construction parts. The landing gear has been strengthened, and the nose gear now has dual tires. The RCS is 1/6 of the Su-27. The 117s engines are not super cruise capable. And the TVC has to be activated manuell with a switch.

I never knew the Su-35 had a bigger wing than the baseline Su-27.
Why? Is it to maintain their desired weight to lift ratio?

Western fighters normally just add better engines to offset the added weight, but does this practice completely address the weight gains or were the Russians right to add a little more wing.

In the F-16 episode of the Fighter pilot podcast, Jello mentioned that the A model of any fighter will be the best dog fighter because this was the lightest?

I knew that was the case for the F-15 because in our Eagle thread, Sprts replied to my question by saying that the F-15A was actually the best turning Eagle of all.

But for the Viper, I always thought the F-16C block 30 with analog limiters will be the best performing Viper. Although the F-16V offered to India with GE-132 engines may challenge that.

For the F/A-18, I often hear that a Charlie Lot XII with GE-404 EPE engines is the best performing.

If people doesn't mind, I'd like to ask
1. Is adding more thrust enough to offset the added weight of later blocks or is the Russian approach of adding a little more wing actually better from a performance standpoint (not necessarily from a cost standpoint)

2. Is the A model really more often the best performing model in American fighters, or were there later models that outperformed their base mode (besides the F-14 of course)

So, I have looked into this and I am 95% sure the added "wingspan" is the Khibiny pods and not actual wing

That sounds very likely. Because some official sites says 14.7m ( clean) and other 15.3m (with Khibiny pods) .
