PAK-FA / Sukhoi Su-57 - Updates and Discussions

LOL, aren't all the ones on display at major airshows just T-50 prototypes? They don't even have the surface putty applied. When have you ever seen a so-called Su-57 on display?


I am sure the "real" Su57 has the RCS of an electron and the range for a round trip to Mars. Till then, us armchair generals can only use the data available-- especially compared to its competition.
 
Stealth != Protection from lucky strikes. If at all enemy AD was even involved with that SINGLE incident, all it showcased was the survivability of the platform.

You and the Iranians can claim "6-0" all you want.

Oh,
since “stealth”≠ “Protection from lucky strikes”, then I'd rather choose “lucky” rather than 'stealth.' Might as well prepare more greenbacks for the Americans and see when they'll revive the F-117 — that 'highly stealthy' but “unlucky” advanced weapon which entered service in 1983 and was retired in 2008, setting the record for the shortest service life of Since the F-86 entered service any jet-powered aircraft since the dawn of aviation. After all, the Americans clearly don't understand as well as Your Excellency folks what kind of weapons are truly trustworthy. Mmhmm.(y)
Because the Americans would rather hold their noses and use the granddaddy B-52 — which got shot down nine times in a single night over Vietnam — than continue using 'stealth' fighters. Isn't that just bizarre?
It just occurred to me — weren't the Americans discussing restarting the F-22 production line a couple of years ago to sell to the Japanese for their F-3 future fighter program? Too bad the Japanese didn't take their American daddy up on the offer. Maybe this is an opportunity — more suitable than buy the Su-57s..
Oops — struck a nerve at the Pentagon again. My bad.

Lower the DeepSeek "temperature" setting bud - that should help it hallucinate less.
We are going off topic.

And F117 still had a longer career than Yang Wei, the designer of your stealth 5th gen, recently purged to XinJiang likely with a missing kidney.
 
I'm saying that even ground-based radars and combat teams launching large missiles have such a low hit rate against incoming missiles (like the 48N6), so a fighter jet (with only 1 to 2 crew members) that has even weaker guidance capabilities would be far less reliable at intercepting incoming air-to-air missiles using lower-overload missiles like the AIM-9X.
- And i said that it is like Tom & Jerry, trial & error, bcoz it is not zenith of technological evolution.
- Low hit rate doesn't mean zero hit rate.
- Like ABM system tracks BMs, similarly incoming AAMs have to be tracked, if pilots desire survival.
- Something has to be done to escape from or disorient missiles.

Regarding the second question, I have actually argued in other posts that if the minimum energy direct confrontation and the demise of value-based aircraft come to pass, the world will no longer need air superiority fighters. I believe future fighter aircraft will become super-large and land-based, capable of ultra-high speeds. Most ground attack missions will return to artillery, FPVs, and large suicide drones like the Geranium. A small number of concrete structures requiring destruction by glide bombs will have to be attacked by unmanned flying wings such as the S70. And this will be won by quantity rather than individual platform performance. With the further development of networks, the method of aircraft carrying air-to-air missiles for secondary launch will be replaced by aircraft guiding surface-to-air missiles...
- All types of options from tri-services are tried in every war.
- Different group of people globally have made their products as per their diversified thinking & it'll continue like that. It depends on geography, geopolitics, economics, management & coordination, etc.
- We might see different size jets, different speed jets, many types & sizes of drones, UCAVs, etc.
- Irrespective or source & target location/position & guided weapon type, all it needs is a good secured continious network to pass accurate target data for passive seeker & approximate data for active seeker.

Aircraft were first used in combat for reconnaissance.
Later, building on reconnaissance, someone casually tossed a few grenades, and that eventually evolved into the bomber.

The earliest fighters, in turn, emerged precisely to suppress the two aforementioned functions of enemy aircraft: reconnaissance and bombing.

Today, the reconnaissance role of combat aircraft has essentially been zeroed out. With the onset of the Russia-Ukraine war... tactical bombing (including anti-armor missions by attack helicopters) has been replaced by FPV drones. Long-range bombing is gradually being supplanted by "cheap surface-to-surface missiles"—namely, the Geranium-136 drone. The sole remaining ground-attack function persists in using cheap iron bombs fitted with glide kits to strike concrete underground targets that drones and heavy artillery struggle to breach.
...The only temptation this approach offers is the price advantage iron bombs hold over specialized bunker-buster missiles.

The moment specialized ground-attack missiles demonstrate a cost advantage over the "airfield–bomber–glide bomb" system,
aviation will be kicked out of the ground-attack mission set entirely.

And with that, the raison d'être of air superiority fighters will be extinguished along with it...

No boars left—no need for hunting dogs anymore.

W.r.t. Su-57 what's your point?

batch procurement of the Su-57 is a viable option, but the critical priority remains the acquisition of aero-engine technology—specifically, securing the licensed production or technology transfer of platforms like the PS-90 or the AL-31F series. By utilizing these baselines as a technological springboard, the overarching strategy should bypass fifth-generation development constraints entirely, committing instead to a leapfrog paradigm focused directly on sixth-generation propulsion and airframe architectures.

Yes we immediately need to start 6gen engine JV along with domestic effort.
IM🧅, like China used RD-93 & AL-31, we should use Iz-177 till domestic &/or JV engines arrive.

It is very difficult to beat others on their own track; therefore, we should consider creating a new track of our own. Because war is not a friendly race—it is a life-and-death struggle. ------------------ The recent forms of warfare, including North Korea's military developments, are highly worthy of study and emulation.

In fact, the composition used by China is: CMF-56 > RD-33 > AL-31F.

It'll take time to build our own track (engine), till then we need interim engine, not sit idle for 10-15 years AGAIN repeating bad history.

Crazy to think that Russia is gonna deploy their second 5-5.5th Generation Aircraft before the AMCA. @Hyperactive ADD was right, apart from the Americans, no country can compete with the military industrial complex of the Russians and they are more pragmatic and realistic than American's in their approach. I felt that Russians were better Aircraft makers than American's for quite some time but people tend to confuse the affects of the collapse of the Soviet Union and their lost decade on their industrial complex as somehow a lack of their capability which is obviously not true.

Su75 Checkmate is Russia's first single engine aircraft and I like it for a lot of reasons,

The control surfaces on the Su-75 is quite unique - or maybe even revolutionary! It would be interesting to see what effect the extreme angle the inner flaps would have on aerodynamics (esp maneuverability). The beaver tail is yet another quite unique innovation.

Makes sense since the Russia's Su57 was the first to employ a lot of things like Levcon's which other 6th gen designs wanted to copy, Russia is simply ahead of the curve than everyone in this matter. Not to mention the multiband arrays and such.

First jet after the Americans and Chinese to employ Diverterless Supersonic Inlet with performance optimal for transonic speed which is the critical range of speed used in operation like air combat and high speed low level penetration. The intakes also being close to the nose will prevent a well developed boundary layer from forming and hence the intake will encounter a thinner boundary which will make it easier for the DSI to divert low energy air before it reaches the engine, this seems like a good design compromise.

The Su75 is everything the F35 was supposed to be but failed at doing so, Su75 will be a low cost stealth jet which will be relatively cheap to procure. From what I can gather here and there the competition might be completely overwhelmed and in shock when they see the price tag. They won't believe it or it's impossible or it's just an outright lie! It is even expected that operational cost per hour of the new Sukhoi fighter will be six to seven times lower than that of the F-35 and for the price of one Indian Rafale buy eight to eleven of these while it's a generation ahead. Even if the checkmate costs twice as much as expected, judging by the price to operate them, it's a bargain for everyone.

The Su75 has 30% range than F35, almost similar weapons payload capacity and able to carry 5 BVRAAM missiles in stealth configuration, higher service ceiling, It will also feature an open architecture to integrate non russian systems, it will also probably have a multiband array for stealth detection, an EOTS system under cockpit like F35 and J20.

I would like to hear other's opinion as well.
