Seems like India is woefully unable to maintain and fly their jets, aircraft far less developed countries operate with little issues. But it's not like they're a gold standard with regards to military aviation anyway.

About India ,IAF and their operational experience in the fighter aviation through many decades.Yes, there is that issue with the technical/maintenance staff ( so called ''technical culture'') , than atmospheric conditions which are very specific for the ''Indian subcontinent'' : very hot troposphere with much moisture and that 'sandy air' phenomena.All those atmospheric conditions don't know the difference between Russian and western made aircraft. Almost all technical problems with Su-30MKI were the problems with licence built ones.

Su-30MKI and why this large/heavy fighter has so big forward RCS even unarmed.

Yea but other countries apart from russia and china dont operate on the same scale and this was 10 years ago when India barely had any domestic spare parts production n stuff.

The rafales on the other hand have maintained a 80% + serviceability rate.


but like i said its gotten a lot better over time and is alr right now apart from accidents. I think India recently ordered 240 AL31FP engines from HAL so i assume they've sorted out most issues by now. domestic spare parts has helped massively.

Indian bureaucracy is absolutely inscrutable, from what I understand the appropriate government body has declared that there is a necessity for the upgrade (Acceptance of Necessity), and has drafted a budget request. This was a couple years ago, but there hasn't been any further news regarding acceptance of that request, which should've first been on the agenda in early 2025. The design work can't begin before the budget request is cleared, I don't think their state design bureau can foot the bill internally.
Might as well be a paper project, the design simply doesn't exist except for fanciful speculation.
Its got its draft recently and CCS clearance(final) is probably going to happen in 2026-2027(2027 being worst case scenario). A lot of the radar stuff etc have alr been selected and design finalized and the subsystems are getting tested rn. As for why its taken so long the DcPP took a long while to get selected but its all done now(at least to the best of my knowledge)

there is also talk for a seperate 175 plane upgrade(cause the Indian upgrade is taking a while) using russian stuff but this will probably use russia for structural reinforcements while India uses its own radars and mission computers.


As for the CAG report that was in 2015 when HAL was in phase IV of its agreement with russia where 55-60% of the aircraft was made in India by volume but only 13% by value. There was a massive lack of spare parts, it was post this 2015 report that India and russia drastically expanded spare parts production for critical components in India.

HAL is also severely to blame for sub par quality although it seems to have gotten better over the years thankfully with the newer builds having a lot less problems

Are there any plans to upgrade Su-35S may be with more modern AESA radar from Su-57 program or the current IRBIS radar is considered good enough and can be further upgraded ? Thank you

That first mentioned...

There is no such a plan yet ( for AESA). Su-57's N036 Byelka radar system with its eight AESA is unique and can not be integrated into another fighter.

I doubt it. I think AESAs will be reserved for MIG31 and new SU-57.


MiG-31BM has PESA N007AM.

Does it need it? Isnt IRBIS E an Insanely powerful long range radar although the performance vs VLO leaves a lot to be desired?
 
Nothing special but ....

Су-35С прикрыл вертолеты армейской авиации в зоне СВО. Видео​


''Истребители ВКС обеспечили безопасность армейской авиации при нанесении ударов по позициям ВСУ. Авиация продолжает круглосуточное патрулирование в зоне проведения СВО.''

The Su-35S provided cover for army aviation helicopters in the SMO. Video

''Aerospace Forces fighters provided security for army aviation during strikes on Ukrainian Armed Forces positions. Aviation continues to patrol the SVO zone around the clock.''


Four years of intensive use in those patrols. There was a pilot who logged 800 flying hours during the first year of the war and wonder, how many flying hours majority of Su-35S ( and also Su-30SM/SM2) fighter- pilots logged during this 4 years. Invaluable experience....

If you install the AESA radar, then the su35 will lose the ability to rotate its radar
 
Considering that N035 is half-AESA already, I don't think it's too hard to make pure AESA dish in place of an old one
 
Cant they improve the current IRBIS-E performance considering they have 4 years of experience operating Su-35 and its radar in real operational war conditions ? They may be aware of its good point and shortcoming that needs improvement , Improving Range , A2G/A2A/SAR/ISAR mode , ECM/ECCM capability other software driven improvements based on experience.

It would be good to have Ga/N based internal and external EW jammer suite , Towed Decoys , DIRCM , Improved IRST ,New 360 * MAWS , Wing based L Band Radar as part of its modernisation.

Building state of the art digital radars requires not just advanced chip manufacturing and board integration facilities, it requires a lot of stuff that's very specific to miniaturizing T/R modules. Only a handful of companies have these capabilities globally. None of them are in Russia. Russia can build AESA radars just not to the same level of quality.

On the other hand, Russian companies are quite competent with high power non chip solid state microwave devices like klystron tubes. Given their constraints their choices are reasonable engineering tradeoffs. So PESA is preffered to AESA, both from the point of view of accesibility of components and also from the point of view of cost versus effectivness.
 
AESAs(unless we consider solutions which aren't really deployed yet) tend to have thick and heavy front end.
Gimballing it in fighter nose conditions is troublesome.

It isn't the only way (early in development they considered V-shaped installation as alternative to gimbal), but this will be a major redesign.

Does it need it? Isnt IRBIS E an Insanely powerful long range radar although the performance vs VLO leaves a lot to be desired?
Range v VLOs(in narrow pattern) is probably its main reason of Irbis existence in the first palce. Long range is happy by-product of this metric.
In everything else it's relatively mediocre(mediocre=not outstanding; nothing especially bad).

There was story from 2023 about ''modernization'' of the Su-35S .Alexander Pekarsh from KnAAZ told to TASS then.

''Получаемый в ходе проведения специальной военной операции (СВО) опыт позволяет быстрее модернизировать сверхманевренный истребитель поколения 4++ Су-35С.''

''The experience gained during the special military operation (SMO) allows for faster modernization of the super-maneuverable 4++ generation fighter Su-35S.''


For all these years we could see new wingtip jamm stations e.g.

What difference between PESA and AESA specifically in VLO detection? What AESA can offer that PESA can't for this use case?

Russia is already produces AESA radars for Su-57. You know, the same radar program that gave birth to N035 as stopgap/backup in case N036 development gets too protracted.
And how would you compare quality? Where is a data for such bold claim?
 
Range v VLOs(in narrow pattern)

This is strange. If this narrow pattern thingy refers to aperture foreshortening where the antenna beam broaden as the beam are steered electronically farther from centerline, this affect both AESA and PESA equally.

Measure to counteract them is also similar (e.g increase in dwell time or power)
 
Interesting, but do we know it's for Su-35? Sure we see a Su-27 family aircraft in the rendering, but maybe it's more of a placeholder and the upgrade is intended for the earlier Su-27/30?
 
it's only a model and the count was made on a render image
Judging by radar in front it looks like AESA for Ka-52 or other helicopter, that made by Phazotron. And Phasotron made Zhuk-A radars for MiG-29/35 that look like shown here so It's a safe guess that it's indeed another variant of it (how long they gonna beat that dead horse? It's what, 5th iteration of design?) and Su-35 is shown as render image.
Additionally, Phazotron usually works with MiG/heloicopters and Sukhoi has it's own parner - NIIP, that made N001, N011, N035 and N036 for Su-57.

Pretty sure only su-35 has the 2 massive multifunctional displays. Other models of flankers have different mfd arrangements
 
It is true, but that may be part of the upgrade. To me those MFDs don't quite look like those on Su-35, but this is just a rendering so there is that. Imo if there will be an AESA for Su-35 and Su-30SM family surely one based on the N-036 front array makes a lot more sense?
 
Once upon a time.... there was a brochure for the L-band phased array and intended for the Su-27/30 ,even for the Su-35S . Of course we know that only fighter which got it is Su-57.

This thing is a placeholder.

It is such a waste and illogical to have lower module count. That 896 TRM counts indicates the thing will operates at C-band which no fighters are doing and effectively killing not only resolutions but also backward compatibility with weapons, say R-27's.

The only way this could be X-band is to sacrifice electronic beamsteering capability to some 10 degrees (+-20 deg of arc in total) or just being smaller overall which a waste for a large radome such as one in Flanker.

didn't Zaslon use C or L band?
 
BTW, what was the module count of zaslon?

1700

This is from "Survey of Russian low cost Phased Array". The MiG-31 part have error in FOV which supposed to be 35 degrees, not 70.

The beamsteering angle is curiously mentioned in a catalogue, as "possible shift of view center"
