There is no indication of the lifetime of the engine, otherwise it is quite impressive!

I knew that it was a variable bypass engine or variable geometry engine.

What's interesting is it will be the most advanced operational engine until the next American engine comes in during the 2030s. So at least for some time the Russians would have taken the lead in engine technology.

Japanese have new engine, which could surpass russian one.

Unlikely. The Japanese engine is a standard design similar in class to the F119 or F135. It's not VCE.

VCE is part of next gen American designs that came out of AETP. So the Russians got there first, after both countries failed in the 90s.

So what u are thinking now? We backed off from SU57 is an act of stupidity or not?

Russians have reduced the gap already. The new engine for their new airliner is nearly same in performance as the latest from GE and PW. The difference in SFC is just about 1% between the geared fan design of PW and PS-14.

There are two ways to optimise the performance of an engine? one is to design an engine which meets all your needs all across the operating spectrum or design an aircraft around an engine wherein the performance of the aircraft and the engine are optimum. Stealth aircraft do not need to fly low so an engine optimised for high altitude operations with VCE is better IMHO.

It's not. The Russians would create problems with ToT, just like they did with Brahmos, so it's not like we will actually benefit from their R&D capabilities. They have a habit of backtracking from promised committments as well. Also, the IAF is now much more interested in creating technologies inhouse rather than importing. Once MRFA is done with, only indigenous products will be produced in India.

We can always import 40-80 Su-57s if necessary, this much is more than enough considering drones will become the mainstay of airpower in the future. Plus the insane range of the Su-57 covers the entire Indian mainland with just one airbase, so two airbases with 2 squadrons each are more than enough to deal with both Pak and China.

The Okhotnik is the Russian Ghatak.

The pilot of the fifth generation Su-57 fighter will simultaneously coordinate the actions of four newest Hunter heavy attack unmanned aerial vehicles (UAVs). This was reported to TASS by a source in the aircraft industry.

"Now the possibilities of controlling several attack drones from the cockpit of the Su-57 are being worked out. It is assumed that the fighter will carry from two to four Hunters with it," he said.


TASS has no official confirmation of this information.

As previously reported to TASS in the press service of the United Aircraft Corporation (UAC), the newest UAV "Okhotnik" will hit air and ground targets as part of network-centric interaction with the Su-57 fighter. When used together, the drones will solve a full range of tasks, working on air and ground targets under the command of the leading manned vehicle.


The Su-57 is designed to destroy all types of air, ground and surface targets. The aircraft has a supersonic cruising speed, internal armament, radio-absorbing coating ("stealth" technology), as well as the latest complex of onboard equipment.

Developed in the Sukhoi design bureau, the S-70 Okhotnik UAV is made according to the "flying wing" scheme with the use of "stealth" technology, which reduces its radar signature. According to open sources, the takeoff weight of the vehicle is up to 20 tons, the maximum flight speed is about 1,000 km / h. Serial deliveries are planned to begin in 2024. The Hunter took to the air for the first time on August 3, 2019, the flight lasted more than 20 minutes under the control of the operator. On September 27 last year, the UAV flew together with the Su-57 fighter.

The order for the latest fifth-generation fighters, the Su-57, may be measured in hundreds of units. This was announced by the General Director of the United Aircraft Corporation (UAC) Yuri Slyusar during a meeting with Russian President Vladimir Putin.

"We hope that, of course, since this machine has been chosen as the platform, the main machine for solving a wide range of tasks, the order for these machines will be measured in hundreds," he said.

According to him, development of several versions of this machine is expected to begin this year. “This year we will deliver four cars already. And then our task is to reach the level of 12 cars a year together with cooperation,” Slyusar noted.

The general director of the UAC recalled that a contract has been signed with the Russian Ministry of Defense for the supply of 76 Su-57s.


The Su-57 is a fifth-generation Russian multifunctional fighter. Designed to destroy all types of air, ground and surface targets. It has a supersonic cruising speed, in-body armament, a radio-absorbing coating, as well as a state-of-the-art complex of onboard equipment.

For a westerner ( he's Italian , ex Italian AF & an aeronautical engineer ) , his views & analysis are surprisingly free of the usual bias one expects of the Russians .

He's done a good job summing up the various features of the Su-57 along with a decent analysis of it's strengths & weaknesses & how it compares with similar western aircrafts namely ones USAF flies.


Your take on it . @Picdelamirand-oil ;
