I wont even comment om this, sinse it so long into the future.
But one thing is a given. VVS do not have unlimited access to funding.
The Pak-Fa program has to stay within it bounderies of budged.

No one has unlimited budget but we’ve seen the evolution of Su-27 family over the years with budged bonanza and scarcity of money to think PAK-FA can’t repeat, at least partially, the success of T-10.

Wrong. First the singel crew Su-50, then the singel crew Su-50M.

There will not be any two seater. Sukhoi, Russian MoD and VVS.. i’m not sure whom, just pick one;) has decided to drop the two seater.
VVS has never been a great fan of two seater among their jets.
Until the Su-30SM enters service, there is pretty much the Mig-31, Su-34 and Su-25UB and a few Su-27UB, the large Flanker fleet is singel crew.

Why don’t you think Russia has decided to go the same route as US, both F-22 and F-35 is singel crew.
They would save large amount of money, time and production output by only go for singel seater.

I don’t know if I’m right or wrong but you’re in the same boat.

Indian officials spoke their minds too early and now are backpedalling, that doesn’t mean that PAK-FA program has changed. If India wants to end this decade with a 5th generation aircraft the single seater is their only option.

VSS sports a plethora of double digit SAMs virtually all Su-30 family customers can’t afford and also VSS is not short of bombers. Since cruise missile lobbing have become the modern epitome of human waves USAF can rely on single seaters for their usual target practice but that’s not the case for many nations that face border conflicts against more even forces. Su-34 is not going to fully replace Su-24, that sooner or later is going to be retired at home and abroad what crates another gap

Not now and maybe not in the coming decade but at some point exports customers are going o need something more beefy than a single seater with not very stealthy pylons to replace their two seaters and bombers so is not far fetched to expect some type of replacement made in Russia to cover those gaps. What it may be? I don’t know but looking at Su-27 family the development of a multirole tandem or side-by-side PAK-FA incarnation in the future is plausible in an evolutionary approach as the base platform becomes more mature.

Surviving tree level crashes is usually more easier than plummeting to ground from high altitude.

Crowded environments are prone to confusion, is not necessarily a technological problem.

Defeat IADS? Seriously?

The last time an airforce faced some working SAMs it suffered more losses by friendly fire than by any system operated by the enemy.

African countries are not known for their strict safety measures so any loose regulations while handling explosives can be extremely dangerous or maybe just South Sudan sabotage if they are planning another round with their northern neighbors.

Buildings, machinery and supplies are easily replaceable in a short period of time, not so skilled workers so if the explosion was caused by an aerial strike the timing could have been better if finally it’s confirmed, or hinted, the Israeli involvement. But is not like Iran have outsourced their ballistic missile program to Sudan.

At this stage, Iran playing the victim is far more dangerous than any missile. The global outrage of an Israeli or US made Chernobyl/Fukushima if any radation leak reaches nearby population centers would be atrocious.

The F-15 and F-16 serach for the target by using its own radar , so F-22 can use its ALR-94 to track enemy in totally passive way , and then fired AMRAAM like anti radiation missile – so the target don’t even know who shoot them down .

And if the target is not emitting? :rolleyes:

Nonsense.

You can’t compare things that transcend technology using stealth as measurement.
