It is unclear if they refer to Su-57 with current engines or not…

In any case it is not the same to “supercruise” at 1.8 or 2 M than barely maintaining M > 1 for some minutes. The first has a clear tactical value, the later, not really. We don’t know what the izd. 117 allows to do. The designers said that it fulfilled the MoD requirements, but clearly an engine as izd. 30 (designed for supercruise) should improve over that by a big margin, so what were the original requirements? Was there a “nice to have” requirement that latter evolved into a “must”, as the progress with the design of the izd. 30 allowed for more ambitious goals? IMHO and all that being considered, the Su-57 with the current engine maybe cruises at 1.2 – 1.3 M, maybe 1.5 M being very optimistic, with the second stage engines should be close to 2 M.

IF you read the full quote they are referring to current engine , You cannot talk about something that does not exist other than prototype.

The interview of Deputy Chief of RuAF I posted also spoke of Supercruise exist for PAK-FA.

As far as SC at what mach number I think that would vary depending on Fuel load and weapons load it is carrying.

Hero of Russia spoke about the Su-57 fighter, which the VKS are proud of

MOSCOW, Aug 25 – RIA News. The Su-57 fighter is the pride of the VKS, it has no analogues in the world, said test pilot, Hero of Russia Yuri Vashchuk in an interview with the weekly Zvezda .

“In addition to the minimum visibility for radars in all wavelengths, including infrared and radar, the aircraft has super maneuverability and the ability to evade enemy attacks at supersonic speed without afterburner. Plus, the aircraft is multifunctional and can solve both the tasks of gaining superiority in air and work on ground and surface targets, “said Vashchuk.

He added that, in addition, the qualities of Russian pilots should be taken into account, in particular, their decisiveness and desperation, as well as skill.

“If our pilots could show real miracles of heroism on plywood planes during the last war, then imagine what they can do on such a machine! I do not advise anyone to experience the power of the Russian SU-57 in their own skin!” – emphasized the pilot.

Vashchuk also said that work to build up the combat capabilities of the latest fighter still does not stop.

I partially agree, but it is a suboptimal solution. The main advantage of MiG-35 is that it is already available. The airframe was created at a time when it was apparently not possible for the Soviet Union to create a single engine aircraft of enough performance, today it would be much better to design a lighter plane using one of the already available engines for heavy fighters and include basic shaping for signature management, modern aero and other state-of-the-art features. In the end it should be no different than Su-35, a temporary measure until an up-to-date design appears. In fact there are doubts about whether Rusia wants the plane beyond their need to keep MiG afloat, if they at least win the tender in India, the company would be finally safe over the medium term and we would see the real interest of the VKS, until now the only real trend, despite nice words from the politicians, is the substitution of the MiG-29 squadrons with Sukhois. State tests still running and not expected to be finished until 2021, for a plane that is essentially a MiG-29K? Seems a bit weird to me, maybe they are just making time until the India tender is finished.

As they say Perfect is the enemy of Good Enough , Mig-35 is good enough to be competitive for next 25-30 years if bought in numbers it will turn out to be cheaper than all flanker series and less costly to maintain.

The other aspect is UAC and its design bureau is fully loaded with many projects in Civil and Defense. From 20 seater to 400 seater in Civil aircraft and every thing in between and many defense project , Not to mention besides technical man power funding is also an issue.

“Another HAL executive said a formal request has been sent to the Indian Air Force and the Ministry for Defence that they place an additional order for 72 locally made Su-30MKI fighters for about $5 billion, but the government has not yet made a decision.
A senior Air Force official said the service could only order 18 fighters as a response to the number of Su-30MKI jets lost in accidents over the last two decades.”

“Each HAL-built Su-30MKI fighter costs around $70.3 million, where as a Russia-supplied fighter costs around $42.15 million,” the senior Air Force official said.

“The HAL built Su-30MKI fighter is not fully indigenized, only 51 percent is homemade, where the remaining 49 percent of supplies still comes from Russia,” said Bhim Sigh, a retired wing commander with the Indian Air Force.Singh noted that most of the raw materials are sourced from Russia, including titanium blocks, forgings, aluminium and steel plates, as well as low-tech items such as nuts, bolts and screws.”

The official cost of HAL built Su-30MKI is pegged at $60-61 million that has been put up multiple times by MOD in Parliament.

Coming back to cost difference bettween Russian Supplied Kit and HAL Built one , MOD recent clarification on cost difference https://www.livemint.com/Politics/D4BrJrynbpn7qjet1fX7lO/Indigenous-Sukhoi30MKI-costlier-than-Russian-SU30-as-speci.html

Minister of State for Defence Subhash Bhamre, in a written answer to a question in Lok Sabha, said the higher cost of indigenously manufactured SU-30MKI is due to factors such as additional modifications incorporated in the plane to enhance the operational capability to suit the Indian Air Force’s requirements.

The minister said that being a transfer of technology (ToT) programme, cost is involved towards payment of license fee to the Russian side.

Owing to the low volume of production of Indian SU-30 MKI as compared to Russian SU-30, economies of scale come into play, Bhamre said.

Import of raw materials and proprietary components from Russia involves dependency on Russian Original Equipment Manufacturers (OEMs) for the offered kit costs, which are not proportionate with the kit contents, he said.

The minister, however, asserted that indigenous manufacturing has created advanced skill sets in the country, a step towards self-reliance and will result in lower life cycle cost and reduced dependency on OEM, repair, maintenance, faster turn-around time, and quick support to IAF bases.

Since the facilities are indigenously established, future production supplies is likely to be cheaper if new order for bulk production is placed on HAL, Bhamre said.

Any reason why Su-30SM is not seen carrying R-77 only R-27 variant and R-73 , Which variant of R-27 does RuAF have atm and have these been modernised since the 80’s with better electronics or Active variants ?

The Mirage was a much better multirole fighter from IAF pov while Mig-29 excelled in AD exactly the reason why it was purchased by IAF to counter PAF F-16.

I read from Mirage pilot twitter that Mirage-2000 was better in BVR to do better RDY/R530 AAM over Zhuk/R-27
