Su-35: not as good as we would like?
Probably, it’s worth saying right away: the arguments that will be discussed, they were invented there. And the fact that some of our bloggers and the media picked it up - the author is not responsible for this, because it was not invented by him. The sources of the dope that we are going to talk about are there, beyond the seas.
Aviation Magazines, Naval Aviation News, Drive, National Interest, 1945 - in general, you understand, I hope, where stabilizers grow from. And the fact that we are trying to give our own assessment of this - why not?
Deliberately almost not a word about the Su-57. This aircraft does not exist, but when it appears in kind in combat units and starts to really fight, then we'll talk. So far, this is nothing more than a prototype. This means that the Americans correctly consider the Su-35S the most advanced and dangerous aircraft of the Aerospace Forces. And in which case, it is with this aircraft that you will have to deal in the air, no matter which state. Therefore, the Su-35 is quite understandable attention.
Naturally, the Su-35 is no match for the best, but obsolete F-22 fighter in the world and no less than the best F-35. And in support of this concept, several arguments were invented there, which I would very much like to go through.
Argument #1. Su-35 is a modernization of the Su-27, and therefore with an interference 4+ generation
To deny that the Su-35 had a predecessor is stupid. Yes, the plane was not designed from scratch, like the Raptor, it is. However, if we take into account that the Su-27 was an extremely successful aircraft, then even as its further continuation, the Su-35 is at least a machine no worse.
However, if we are talking about what distinguishes these aircraft, then we get the same list:
- the geometry of the airframe has been changed, moreover, it can be seen with the naked eye;
- if you believe the manufacturer (and why not believe him), then the power set has been changed taking into account the operation of the Su-27;
- the centering of the aircraft is shifted towards the tail;
- increased volume of fuel tanks;
- new engines with variable thrust vector;
- new avionics and radar;
- certain steps to reduce the EOP.
Here, of course, everyone will be able to decide for himself how many pluses should be added to the four, two, three or four, in order to characterize the difference between the aircraft. It is so great that it's hard to talk about modernization.
There is historical example: so the LaGG-3 was “modernized” into La-5. Well, yes, a different wing, a different nose, a different engine, a different cabin, a different set of weapons. Actually, only the tail section remained from the original car, but until now, some "experts" seriously say that the La-5 is a modification of the LaGG-3.
But if so, then yes, the Su-35 is a modification of the Su-27. But, in fact, this is a completely different plane.
Argument #2. The AL-41F1S engines are a modernization of the AL-31F, so they are hardly capable of 4++, and aircraft with such engines do not pose a significant threat.
I don’t know why the brave guys from Military Watch Magazine gave it out, what difference does it make to them in these pluses, I would go a little differently here.
Well, the Su-35 is not the fifth generation. Fourth plus sign. And it has an engine developed from a purely fourth-generation aircraft engine. But let's look at the fifth generation, the Raptor. Did he develop an engine from scratch?
No, the Pratt & Whitney F119 is a very brutal overhaul of the good old Pratt & Whitney F100, which has been stamped by over 7 and still flies the F-15 and F-16 pretty well. And no one in the United States tears their hair and howls about this, that the “fifth generation” of the engine is a modernization of the engine from the seventies of the last century. And we have, too, this is completely normal.
But the fact that our 4+ modernization has an all-angle thrust vector (16% in any plane), and the fifth generation engine from the USA is only vertical - well, this is a question to consider.
As for the AL-41F1S itself, then, of course, it is interesting. I would call it a fat-free version of the AL-41F1, which is supposed to carry the Su-57. AL-41F1 is not the next step from AL-31F at all, but a mixture of AL-31F and AL-41F, where AL-41F is a development for the MiG 1.44 project.
The fact that in numbers our engine is a cut above that of the Pratt and Whitney product - well, there is such a thing. There is both power and thrust vector, that's all.
Yes, the letter “C” in the AL-41F1S is a kind of simplification and reduction in cost, since, unlike the original AL-41F1, the Su-35 engine has an old electromechanical control system and thrust is 500 kgf less.
But the main thing, probably, is that the AL-41F1S is in no way inferior to the “fifth generation” engine from the USA in all respects. And in some ways it excels.
Argument #3. The Irbis radar does not at all meet the requirements of modern times and is not capable of performing tasks in air combat.
A lot has been done here: the Irbis radar cannot interfere, and it will see the Raptor from 20-30 km when it is too late, and in general, the PFAR is not a cake.
Partly yes, the Irbis, of course, is a bit old compared to modern radars with AFAR, but: so far it is the most powerful (20 kW) radar in the world in general. With pros and cons. Of the pluses, the viewing angle is twice as large as that of the AFAR (120 degrees versus 60) due to the electro-hydraulic mechanism for turning the grating, of the minuses - AFARs, of course, see further.
Jamming with the help of AFAR - they have already said, it's a so-so idea. For now, at least. Theoretically, yes, quite a working idea, in practice - not for every aircraft and pilot.
As for the fact that the "Irbis" "will not take" the F-22 and he will shoot him like a duck - it is very doubtful. If we accept that the EPR of the Raptor is somewhere around 0,03 - 0,05 sq.m., then the Irbis can detect such a target from 80-100 km. This is a sufficient distance in order to respond appropriately.
Yes, the Raptor will see the Su-35 from a greater distance, here it will be 120-150 km. And what's the point? Launching missiles from such a distance is senseless and merciless. In addition, the launch of a missile is a process detected by the onboard defense system with all the ensuing consequences. Yes, in fact, our opponents do not yet have missiles capable of operating at ranges of 150 km or more.
So there is such an original parity here: the Raptor will see the Drying earlier, but there is little sense in this, since they do not yet have missiles similar to our R-37M. Su-35 will see a little later, and in the end everything will turn to a trivial fight at a medium distance.
And, by the way, when we talk about medium distances, it is completely optional to shine with a radar and impersonate yourself, the OLS of any aircraft can lead a target in the forward hemisphere of kilometers from 50.
Of course, the fact that Irbis takes its toll at the expense of power is crutches. But AFAR is a completely normal prospect for this aircraft, as one of the options for upcoming upgrades.
Let me jump ahead, because the Sukhoi company and, in particular, the press service of the plant in Komsomolsk-on-Amur issued information that by 2025 the modification of the Su-35SM will go into part, in which a revolutionary replacement will be made H035 "Irbis" on a certain product "Irbis-E" with AFAR. And a nice bonus would be the installation of additional L-band wing-mounted radars (as I understand it - H036 "Belka" from the PAK FA development), which not only provide a view of the rear hemisphere, but also can additionally work out just for inconspicuous objects in the air.
The L-band is in the 1,0 to 2,0 GHz radio frequency spectrum with wavelengths of 15-30 cm, while most stealth aircraft are designed to avoid X-band radar waves.
So stealth and long-range radar are, of course, a very weighty pair, but the complex decides everything. And here we move on to the next argument, which is even more controversial than the previous ones.
Argument #4. Supermaneuverability is useless in modern air combat. Solves all stealth.
In general, of course, to expect something different from the Americans is simply naive. The concept of application is what to do.
However, stealth and smart radars, as I said, are half the battle. Here it would be nice to have long-range missiles and excellent defense systems.
Stealth is good, but it will not be decided by it, but by the effective launch range. The sooner the rocket is launched, the more likely it is to be discovered and they will either leave or fool the GOS in a variety of ways.
Let's just remember the last air battle between the Indian and Pakistani air forces. Almost five dozen planes hung in the air, launched rockets, so what? And nothing. Until one crazy Indian pilot on the MiG-21 broke the distance and went on the attack, nothing happened. And so the Indian shot down the F-16 and was himself shot down by a pair of cover. But all this happened when the distance passed into the category of small ones.
In general, the fact that a rocket can fly 200 km is not the main thing. Just flying over is one thing, maneuvering, as the target, imagine, can start to evade is another. And any maneuver simply devours fuel, reducing the range of the rocket. Do not forget that any rocket - weaponwhile the engine is running. Then she flies, maneuvers, the GOS works, correcting the course and everything else. And when the fuel is all - and the rocket practically no longer threatens anyone.
And it turns out a very simple alignment: the shorter the distance from the maximum a rocket is launched, the more chances it has to reach the plane. From here, no launches from 200, 150, 100 kilometers. All the same combat distance of 20-50 km, regardless of which missile to shoot - medium or long range.
And here, on the one hand, stealth is good: a seeker with active radar guidance, that is, a mini-radar, can “lose” an inconspicuous aircraft. On the other hand, the ARLGSN is not a single aircraft alive. There are other options with which the approach to care is different.
Supermaneuverability in close air combat is very useful. The ability to “break” the missile’s flight path is useful in itself, plus an actively maneuvering aircraft can simply “wear out” the missile, which will eventually run out of fuel and turn into a blank.
By the way, the Americans themselves were perfectly convinced of this when they clashed in training battles with their super-maneuverable X-31 aircraft and the battle-tested F / A-18. 8 out of 10 battles were for the X-31, in whose arsenal was both the Pugachev Cobra and the Mongoose.
Of course, getting away from a missile that has captured a target is not easy. But the faster the rocket flies again (and they are all from 4M in speed), the more difficult it is for it to maneuver. This is physics that cannot be undone. And here the super-maneuverability of the aircraft can be no less useful than stealth. At least in terms of usefulness, these qualities are comparable.
Argument #5. Su-35S does not have long-range missiles, which means ...
This does not mean anything, no matter what colleagues from Military Watch Magazine and 19fortyfive say. Huge two-stage long-range missiles are good for working with them on such targets as a strategic bomber, AWACS aircraft, air tanker. Shooting them at a maneuverable fighter or fighter-bomber, especially an inconspicuous one, is a so-so idea.
The evil is that the rocket with its frail radar will definitely not see the target from 200+ km, it will need to “shine” the enemy’s radar radar of the aircraft or have (the American version) an AWACS aircraft behind its back. And if the second option is still all right, the A-50 also copes with such a task, then here is the target designation of its radar ... Well, in general, in a chivalrous way: “We deigned to attack you!”.
Initially, such combat missions were not set for the Su-35, the aircraft, being a continuation of the Su-27, was first considered as a “clean” fighter, which should have been able to bring any enemy in the air to the scrap metal collection point.
And for this, the Su-35 had everything: medium-range air-to-air missiles R-27ER1, R-27ET1 and R-27EP1, RVV-SD, and R-73 melee missiles.
However, in 2020, “sighting” launches of the R-37 took place, that is, certain work was carried out in this direction. Moreover, it is the R-37M in the upcoming modification of the Su-35SM that seems to have a reserved place in the armament clip. But this is a separate conversation, however, if we are talking about a certain inferiority of the fighter due to the lack of long-range missiles (more precisely, they say overseas), then it would be worth looking at the nomenclature of the same F-22. And make sure with your own eyes that the Raptor also does not have long-range missiles.
And nothing, no complexes in this regard.
So if there are no long-range missiles in the Su-35S armament range yet, this only means that if there is a need, missiles will appear. The question here is who to use them for. So far, as the practice of the SVO has shown, the most terrible weapon of the Su-35S is the Kh-31P and Kh-58USHE, which very decently thinned out the ranks of the Ukrainian air defense.
Argument #6. Without an aiming container, the Su-35S cannot be considered an effective strike aircraft.
If I were the guys from MWM, I would go and check in real life how bad the Su-35S is, like an attack aircraft.
Let's start with the fact that in addition to the H035 Irbis, the Su-35 has the OLS-35, an optical laser station, developed and manufactured by OAO NPK Precision Instrumentation Systems. And they know how to build devices there, especially laser ones.
OLS-35 has infrared and digital optical cameras included in one optical unit. In addition to them, there is also a laser rangefinder and a target illuminator. The system is mounted in the nose of the Su-35, its auto-tracking zone is +/-90° in azimuth, - 15°/+60° in elevation. An air target the size of an F-15 can be detected at a range of 90 km in the rear hemisphere or from 35 km in the front. The OLS-35 can track four air targets at the same time, without sending any signals that can warn them of exposure.
The only disadvantage of the OLS-35 is that the system does not look good "for itself", that is, in the lower hemisphere. Which is generally logical, since the system is designed primarily to work in the air, and not on the ground. Su-35 is still a fighter.
However, from those distances that are declared by the developer (up to 35 km), the OLS may well track and give target designation to ground targets in “silence mode”. And, let's just say, this distance, in principle, is sufficient for the safe launch of missiles.
But if you look at the work that was carried out in this area, you can also find overhead container OLS, which are designed to work in the lower hemisphere. And these developments have been going on for a long time, the only thing that is still missing is data on the results of the use of OLS-NT, as the container station developed as part of the T-220 project is called.
In general, if it is necessary to re-profil the Su-35S for strikes against ground targets in full, this will not cause any special problems. But it will be surprising, because for this the VSK RF has a Su-34, which will do it much better. Apparently, overseas experts missed this.
Total. Su-35 is not food for the F-22?
Not food. Alas for our fans of the American fighter, but it is. Here is my personal opinion, dispute it as you like, tell us about the modernization of the F-22 ...
I'll tell you one thing: that's how they modernize - then we'll talk. Yes, the phrase is so-so, but nothing else. Well, I don’t see the “King of the Sky” in this plane yet, don’t prove it here.
Yes, the Raptor is simply gorgeous at supersonic in terms of maneuverability. It has excellent overclocking characteristics. But it was paid for by the voracity of the engines, so much so that without two hefty PTBs, the combat radius causes just healthy laughter. And with the PTB somehow all these internal compartments for weapons no longer look, you yourself understand why.
Stealth - yes, very strong and useful. But the frankly castrated defensive complex and the constant troubles with missiles - sorry, somehow not royally. For an aircraft that has been flying for 20 years - well, yes, you can remember the Su-57, but we are not rushing to the first place, it seems.
Today, the alignment on the arms market has changed somewhat, but let's say yesterday everyone gasped in unison from the AFARs. And they bought planes with PFAR, because they were cheaper, and much cheaper.
We are simply presented with this as the fact that the Irbis-PFAR is backwardness, yesterday in comparison with the radar with AFAR, but due to its power, the Irbis can ensure the detection of the enemy at the same distance as AFAR.
Yes, the Irbis product is outdated, but this does not make the aircraft something backward and incapable of fighting the fifth generation on an equal footing. Considering that the Su-35 has a perfected BKO, super-maneuverability and the ability to “hang” longer and further.
In our world, physics is the same for all aircraft, both third and fifth generation. At least until we master antigravity.
Because the demon is with him, with the Raptor. But if we take even the Su-57 and Su-35, what will be the fundamental difference? Yes, nothing! The Su-57 will not be invisible, this is understandable. He will have more radar than the Su-35, but then again, who prevents Belok from being adapted to the 35th? All the same, the same R-77-1 will be launched from a distance of 50 kilometers, and instead of dividing the radar canvas into zones to perform different tasks, it will be easier to use containers with electronic warfare stuffing. An equal opponent, especially if you keep in mind the Raptor's not the most luxurious set of weapons.
And this is not another stupid “cheers-patriotism”, this is a given today. The Su-35 simply showed itself magnificently in the sky of Ukraine, this is recognized (which is important) by the Ukrainians themselves, that everything that they did not fall from the air defense system was shot down by the Su-35. Except for one case, when the idiot failed to dodge the "Shahed", but this is already a clinic, in my opinion.
F-16s will appear - it will be informative if it comes to fights, but I wouldn’t put even ten hryvnias on the Sokol.
Some of the “zakosy” of the Su-35 of the PFAR type are explained very easily: there was an obsolescence of the Air Force fighter fleet, which had not undergone serious modernization since Soviet times. Su-30 upgrades are mainly export options, fortunately, the aircraft was willingly bought by countries that were not “at the front” of aviation construction.
All that can be said about the upgrades is yes, frankly, the already old Su-30 was equipped with the AL-31FP engine with a controlled thrust vector and the Su-30SM turned out. But this is 2012. In 2021, the Su-30SM2 flew, into which everything that was possible from the Su-35 went.
The modernization of the Su-27 into the Su-27M as a whole was not such, since it mainly concerned the expansion of the strike capabilities of the aircraft and the range of weapons, the flight characteristics remained at the same level, and what to modernize the Su-27?
And with the Su-35 it turned out something like the Americans did with the modernization program of the F / A-18E / F program, one to one. That is, as part of the announced modernization, an almost new aircraft was created. The Americans did it. We also.
Economy and speed - yes, it seems that the Su-35 was created in some haste when it dawned that the aircraft was needed yesterday. And therefore, everything that was “on hand” at that time went to him. But the 35th flew, but the work of tomorrow, that is, the Su-57, for some reason frankly stalled.
But this is a topic for a separate discussion, in general, you can put plus signs after the number “4” as much as you like in terms of generation (and this division into generations itself is a very arbitrary matter), but the Su-35 is a very difficult opponent for any aircraft on the other side of the world , including both the F-22 and F-35. At least, its shortcomings in the configuration are leveled, but the field for modernization is such that the Raptor never dreamed of.
In general, against the backdrop of the frankly stuck Su-57, the topic of Su-35S upgrades is very fertile ground, since almost all the developments on the PAK FA topic can be applied on this aircraft.
