Su-57 Stealth Fighter: News #8

Current contract means the already ordered planes. Your hopes could come true.

They can build them with su-35's engines once izd.30 is ready replace them with it and use tge old ones for su-30 modernization.

So what american short range missiles are they comparing it to that makes this missile 5-10 years ahead? https://www.militaryaerospace.com/sensors/article/14288000/infrared-airtoair-missiles https://www.prnewswire.com/news-releases/rtx-awarded-264-million-us-navy-modification-contract-to-produce-aim-9x-missiles-301854292.html

The upgraded block 2 contract ends in August 2026 where the missiles will have 360 degree infrared coverage engagement. Are they talking about this or the cancelled block 3 which was proposed to have the upgraded sensors with a claim of 50-60% more flight range? If they are going 5-10 years ahead hope they mean the block 3. I was hoping that they were talking about the CUDA or SACM missile design as being 5-10 years ahead.

Su-57 uses Izdeliye 117, as a first stage engine. It is different engine from the one Su-35 uses.

Probably is one of the four received in december 2022 for start a new regiment

First time ever, technical characteristics of the Su-57, and not even related to the E version (?)

I don't know, a crappy photo-edit looks suspect. Would be nice to see the original photo. The numbers did not need to be translated.

Looks about right. First stage engine numbers. Over 200km for 1m2 targets. Ferry range is right. Is something wrong??

That's the problem, it is recycling internet wisdom and the bizarre number translation hides any new information.

I hope thats just for export and not domestic because that is just 2007 F-22 radar level. Edit: I hope the export is based off the 2009 radars that were introduced for the Su-57 and not the radars that have gone through some modifications of newer modules and the 2nd variant of the Su-57 might have newer radars since the avionics upgrade was part of its package.

The numbers are excellent, and BTW perfectly in line with our expectations, that many would have considered optimistic. Max speed clearly above 2M, range similar to that of the Su-35 and way beyond Western competition. Max weight estimations also confirmed, which in turn confirm previous empty weight estimations. And all that are just the very rough numbers that can be published. They are not going to publish accurate, ultimate data for the Byelka etc.

Over 200km for 1m2 targets. 

Which could mean 250km. Or 300km. Or 400km. 

It's the same range as the N035 which is for 5m^2 400km. Literally the n036 is a full AESA of the N035. Which makes it the most powerful radar in use. The thing is it's lighter than N035.

I'm not sure why people are surprised. This info was provided years ago.

Russia's exports are never better than their domestic counterparts anyways, they already upgraded the radars before the megapolis project even took place, but that range is still not bad.

Russian company unveils new Su-57 fighter missile capable of turning around 180° in the air at military forum, 08.16.2023.

Sputnik visited the International Military-Technical Forum Army 2023, where it was possible to get acquainted with the models of new Russian missiles.

This type of armament is developed by enterprises of the Russian military-industrial complex that are part of the Tactical Missile Armament Corporation (KTRV).

Aleksei Elesin, head of the Missile Engineering Department of the Vympel company and one of the developers of the new rvv-MD2 missile first presented at the exhibition, spoke to Sputnik about this advanced weaponry.

"The RVV-MD2 is a short-range air-to-air missile specially designed for the Su-57e multifunctional fighter. during the development phase of the new model, the designers were tasked with creating a universal weapon, the universality of which is the possibility of being placed both inside the fuselage of the aircraft and on an external suspension," said Elesin.

However, the new missile has other distinctive features, the head of the Missile Engineering Department stressed.
"In addition, for the first time on a missile of this class an inertial guidance system with radio correction and a self-guided thermal search warhead of the target were installed.

This allows the pilot to launch the missile towards the air target, then it [missile] enters the flight path and makes the acquisition of the target itself," the expert explained.

"Despite the similarity in appearance of the RVV-MD2 with its previous version – this is a completely new product with a new electronic 'stuffing' that has retained all the advantages. And the maximum range of the missile has been increased to 50 km," Elesin said.

At the same time, the new missile is one of the most maneuverable. He is able to turn right after launch.

"The main distinguishing feature of the RVV-MD2 is the ability to turn 180 degrees after launch. This is achieved thanks to dynamic gas control," he concluded.

I do believe it was Austin (I wonder what happened to him? I miss him) who posted a link download to old publication from flight magazine (Russian) that interviewed rostec and someone else (phazotron?) and they mentioned the N036 and what was its characteristics. So when they initially mentioned detection ranges, it was for targets 5m^2 which was roughly 400km. Because the jets radar is provided 20KW max power, same as the Irbis E. TR modules count made sense too. So even if they had same number if GaN modules vs GaAS modules, output would be the same simply because it's limited by the overall power output provided. Only benefit of newer modules is better cooling or at least less needed and lower failure rate.

Alright so the RVV-MD2 is basically the AIM-9X block 3 which has still yet to reach operation.

It mentions it looks like the R-73 but seems to have proper thrust vectoring instead of chunks of metal thrust into the rocket motor exhaust like the R-73 has for hard turns off the rail.

Super high res images of those AAMs around the Su-57 should be closely examined about now...

Ok you meant the radar data. I recall a Russian publication dealing with some comparative figures of N036 and Irbis, I think power aperture parameter was equivalent on both, but I don't have the document at hand. And those were pretty old data, but yes I guess assuming both radars to be equivalent in terms of range is a safe approach. BTW the developer is Tikhomirov NIIP and the article was from them

https://paralay.iboards.ru/viewtopic.php?f=5&t=2933&st=0&sk=t&sd=a&start=17070 So the 2nd stage Su-57 is getting a flat nozzle?

sometimes its a great idea to periodically check the shit they say there.

We had the photo of the test missile for a long time:

Here are the photos of the finished product:

There are no significant changes to the thrust vectoring system, but the missile for sure has most modern digital flight control that will increase the missile performance, and we can also see smaller stabs and new IR homing head togehter with new proximity fuse sensor and sensors for mid-course guidance.

Here is the rear part of the R-73 for comparison:

[Lipetsk] Lipetsk Air Base, Flight School, this is also where the third stage of military evaluation (Войсковые Исптания) of new aircraft or aircraft modernization takes place. Photo dated 05/29/2023. We see 4 Su-57 in one of the parking lots.

I wish they would translate it to Russian Aerocosmic Forces.
