Vadim Badekha, the Director General of United Aircraft Corporation (UAC), a Rostec's subsidiary, confirmed that Indian concerns and technical demands related to the Su-57 have been viewed positively. Responding to ANI, he said all demands from the Indian side regarding the Su-57 are "completely acceptable" and that they are "deeply" in touch with Indian officials.

Another official also confirmed that Russia is willing to work with India on a two-seat version of the aircraft. He said the proposal includes "joint development of a two-seat modification of the Su-57E or FGFA."

So revival of FGFA to avoid sanctions ?

listen, i understand india really needs a fifth gen fighter but the amount of relations we would damage if we bought the su57 in big numbers while the ukraine war is going on right now is so fking high we would permanently stall our future growth. its simply better to bite the bullet or even buy the f35 compared to the su57 because if we buy the f35 we could simply buy a shit ton of russian products to show them that we still care but if we buy the su57 it doesnt matter at all especially since our economy is far more connected to the west compared to russia.
The plane doesnt even matter in the slightest.
This wil affect things like our semicon industry which relies completely on ASML. Its not worth it.

F-35 is pointless. Su-57 needs to be a priority buy right now.
Getting the f-35 is viable only after block 5 and LM will take atleast 5 years to deliver them with no modification ability. Producing su-57 is better because it has the r-37M. Simple as.

if we go for the su57 its going to have to be both single and two seat. The two seat variant will take at minimum 2030(being very optimistic). If india wats true stop gap then its needs something by 2028-29ish.

Why do we have so many russian Simps in india?

Telegram Channel Fighterbomber:

That the Indians want the Su-57D. And it will fly early next year.

D apparently means two-seater.
This is the right decision. A human navigator is better than neural networks, AI, and other such nonsense.
And a two-seater almost certainly means an aircraft with dual controls, meaning the retraining process will be painless. Because right now, there's nothing to train a pilot to fly the Su-57. Just like there's no other way to train a pilot to fly the Su-35S.

Cause we don't have the money to be American simps

Is the channel that much credible ? To know what IAF has talked about with Russian OEM and Russia planning to develop it by next year?

He is amongst one of the most well informed OSINT/MilTech channels on RuAF and its dealings. Many claim that he has ties to certain officials in RuAF. I have not read much about him, so my information is outdated. You can check him out on Telegram.

He was a former Su-34 pilot hence the user name(Fighterbomber). He is very reliable as far as Russian defence industry inside news is concerned.

We don't have to be simps for anyone except ourselves. With Russians, we can dictate the terms and are free to use their weapons as we deem perfect. Same with the French and Israelis(to slightly lesser extent as far as the former one is concerned).

As far as Uncle Sam is concerned, to be their enemy is bad but being their friend is more fatal

 

[Ashwin]

It was reported then that India is not looking at buying the Su-57 because the IAF feels it is a stealth aircraft but the fighter’s ability to carry long range weapons and heavy payload.

India eyes more S-400s with upcoming Putin visit, Su-57 likely to stay off radar

Not only did S-400 record its longest hit during India-Pakistan 88-hour conflict, ability of the system to shoot and scoot in a short time, which allows it to evade enemy fire, was also proved.

AMCA first flight in 2032???? either this article is slop and poorly written or we Can completely ignore the possibility of the AMCA ever happening at this rate. No way its 2032 with all the tenders and stuff coming out rn

India plans to start discussions toward the purchase of Russian fighter jets and a missile defense shield during President Vladimir Putin’s visit this week, according to people with knowledge of the matter, even as the President Donald Trump administration seeks to reduce dealings between the two nations.

India and Russia have a Special and Privileged Strategic Partnership under which discussions for the purchase of Su-57 fighter jets and an advanced version of the missile defense shield S-500 are expected, said the people who asked not to be named as the matter is private. A potential agreement with Russia could complicate any trade deal with the US, which has pushed back against India’s weapons purchases from Moscow.

India’s military is short on fighters and had asked the government to buy more Russian made advanced fighter jets to plug the gap, people familiar with the matter said.

The proposal shows that Indian Air Force crew including pilots will find the transition to next-generation Russian jets easy, and state owned Hindustan Aeronautics Limited is capable of servicing and maintaining the Russian-made fleet, the people said. Moreover, long-range missiles on the Su-57 jets will give the South Asian country added visual range capabilities, they said.

However, talks to buy new Russian military equipment are unlikely to conclude during Putin’s visit, they said.

The Su-57 aircraft has taken to the skies for the first time with the promising fifth-generation "Product 177" engine.
Specialists from the United Aircraft Corporation and the United Engine Corporation (part of Rostec State Corporation) have begun flight tests of the "Product 177" engine as part of the fifth-generation Su-57 aircraft complex.

New powerplant replaces interim AL-41F1 and addresses a long-standing gap in the fighter’s design

New powerplant replaces interim AL-41F1 and addresses a long-standing gap in the fighter’s design

Russia flies Su-57 with Product 177 engine for the first time​

Russia has conducted the first flight of a Su-57 fighter fitted with the new Product 177 engine, after more than a decade of work on a dedicated powerplant for the aircraft.


Until this point, all Su-57 prototypes and production aircraft have flown with the AL-41F1 , an engine derived from the Su-35’s propulsion system and adopted as an interim solution.


The AL-41F1 provides afterburning thrust in the 14.5-ton class and represented an improvement over earlier Russian fighter engines, but it was not designed to meet fifth-generation propulsion requirements. Its architecture predates the Su-57 program and lacks several characteristics expected of a purpose-built engine for a low-observable aircraft, including higher thrust margins, improved fuel efficiency and optimized thermal management.

Product 177 is intended to replace the AL-41F1 as the Su-57’s standard engine. Russian industry states that the new powerplant delivers 16,000 kgf of thrust with afterburner, placing it in the same thrust class as engines used on other fifth-generation fighters.


The engine is also presented as having lower fuel consumption and a longer service life than the AL-41F1, although detailed figures for dry thrust, specific fuel consumption and infrared signature have not been released.

The absence of a dedicated engine has been one of the main technical constraints of the Su-57 program. While the airframe was designed around internal weapons bays, advanced sensors and low-observable shaping, propulsion remained based on a modified fourth-generation engine for more than a decade.


This limited the aircraft’s ability to demonstrate features commonly associated with fifth-generation fighters, such as sustained supersonic flight without afterburner and higher performance margins when carrying internal payloads.

Is this why India rejected the Su57 offer or India wanted the offer with the new engine?

I think IAF is waiting for the dual seater version to fly next year. Su-57 deal will not happen before the Rafale deal is done anyway.

Russia's Su-57 makes maiden flight with new-generation engine

In a press release posted on its corporate website, the UAC said flight tests of the Izdeliye 177 engine have begun as part of the Su-57 aircraft system in cooperation with the United Engine Corporation, a subsidiary of the state-run Rostec group.

Was under the impression the Su-57 was already flying with the Item 30 Engines since 2022. What's this Izdeliye 177 Engine all about ? Or is this the export variety engine ?

I believe Izdeliye 177s are also made to be backwards compatible with the older generation of their Sukhoi jets - kind of like a gap bridge between the 4.5 gen jets to 5th Gen which will use the Izdeliye 30 a.k.a AL-51.

I was under the impression that Russia wanted to export SU-57E with AL-51, now it looks like they might not give that out on a platter ..

Does any one know for a fact what was being offered to India? I-30 or I-177s?

Item 30 or AL-51F1 is different from Item 177. The latter uses the 3-stage low pressure turbine and other advance metallurgical stuff from AL-51F1 in a size form of AL-31FP. So it's a direct replacement(drop in fit) for AL-31FP. Looks like Russians don't want to part with their crown jewel, i.e., Type 30 engines at the moment. Anyways, with 108KN dry(same as AL-51F1) and 158KN wet(AL-51F1 produces around 175KN wet thrust), and 15 to 25% more efficient than AL-31FP in all flight regimes make Item 177 extremely tantalizing proposition for us as it also has 6000hrs lifespan. The figures are perfect for a 5th gen engine and match F119 of F-22 Raptor(while exceeding it in fuel efficiency). Russians are looking to give us entire 'know how' and 'know why' of this engine which we can also use in our MKI UPG. variants.
