Well this is an interesting It's not as clear cut as it may appear. Yes the Su-35 is, in paper, the superior machine in almost every regard BUT, with STOBAR there is a trade off- either heavy fuel or heavy weapons (can be negated to an extent by buddy-buddy refuelling meaning the fighters can take off with heavy weapons loads and low fuel and be topped up in the air).
And sir, you and I know that the effectiveness of these fighters is about a lot more than just the fighters themselves. One has to factor in situational awareness- a CATOBAR carrier would be able to launch a fixed wing AEW/AWACS that would give the Sea Gripens a distinct advantage.
Let me sum up your points once more:
1) Su 35 is superior to the medium class single engine Gripen
2) Ski-jump take off for long range or heavy payload missions, must be countered by mid air refuelling
3) Catapult take off gives the capability to operate more capable AWACS aircrafts and therefore better situational awareness
I agree with all these points and as you said, the mid air refuelling after take off gives you still the capability to carry good payloads, which basically leaves the use of propper AWACS aircrafts as the only real advantage and here comes the really interesting part!
Take the same scenario again, but replace the Sea Gripen with F35C and the naval Su 35 with a naval Pak Fa, what is the result now?
1) Pak Fa is superior to the medium class single engine F35C
2) Ski-jump take off for long range or heavy missions, must be countered by mid air refuelling
3) Catapult take off gives the capability to operate more capable AWACS, which however have limited effect against stealth fighters
So when you can counter the payload issue by refuelling after take off and you have stealth fighters that are harder to detect and could work well in mini AWACS roles (long range AESA radar, with side arrays, long range ESM/ECM capability), a lot of the problems gets ruled out.
Catapult take off is surely a nice feature to have, but the most important point to decide the capability of a carrier is the capability of of it's fighters! A CATOBAR carrier with less capable fighters, will remain to be weak, even with the catapult capability, while a STOBAR carrier with high capable fighters can still have the advantage.
I told you before that I am not convinced that we really need CATOBAR carriers for the future, because a combination of a 65.000t STOBAR carrier with naval FGFA would be an excellent one. And now think once more about the Russian plans for future carriers and the offer to jointly develop them and the fighters for it, it gives us the prospect to have:
- a nuclear carrier in the 65 to 70.000t class
- a naval FGFA with the highest flight performance of all possibly available naval fighters, with Indian weapons and systems
- ski-jump for fighters like naval FGFA, Mig 29K, N-LCA
- most likely catapults (possibly even EMALS, Russia has started such developments) for larger AWACS aircrafts and UCAVs like AURA / Mig Scat
Not only could we get nuclrear propulsions that many people wants for IAC2, but also a capable stealth fighter, while using the already available 4.5th gen fighters that are in the fleet to complement in buddy refuelling or basic air defence roles next to FGFA too. Larger AWACS aircrafts or heavier loaded UCAVs could be used via catapults, which further increases the capability of the carrier. So do we really need to restrict ourselfs to US approval on catapults + US carrier fighters and AWACS aircrafts with operational limitations and is the Russian way really so bad?
