The commentary/focus on the new engines is telling. I'm assuming the production bird that crashed was flying with the old engines, but perhaps not? It was mentioned the aircraft was performing an "engine check" at the time of the crash. It seems unlikely, but is it possible this aircraft was flying with 1 of the new, "2nd stage" engines? Regardless, it sounds like they've run into significant problems, which could mean one of the following things..

1.) There will be delays well beyond what they had hoped. It sounds like they wanted to have it operational in 2023, but now the timeline is "mid 2020's". Anyone who follows Russian estimates of engines/airframes and their IOC dates shouldn't find this very suprising..

2.) The entire SU-57 program is going through a deep dive/soul searching phase, questioning whether 76 airframes being built will do much beyond what just more SU-35's would.

It may be that they decide to continue pushing the new engine, but the production Felon is off. They'll focus instead on getting the new engine in their SU-27SM2's and 3's, SU-30's and SU-35's. Doing so would provide a huge performance boost to an already hugely capable aircraft. Plus, at least a few of those production lines is still open.

Tough call, but whatever's going on - it's not good news for the SU-57..

Su-57 is still not production ready even if they claim it is. Tom Cooper reckoned last year the avionics/armament testing is still incomplete. The recent crash shows at least a faulty FCS if not worse aerodynamic defects. The new engine is not commercially producible so is a prototype itself. Meanwhile every single one of the 400+ F-35 will be brought up to IOC 3F standard so the US has produced 600+ active stealth fighters and Russia has yet to produce one in the same time period and their version relies on engine fan RAM in the first iteration and composite inlet guide vanes in the second and neither are as effective as a serpentine inlet in stealth. The J-20 is more finished than the Su-57 and that's still a WIP.

Russia needs to partner with China on a Stealth Fighter. Yet, question is will the Chinese have them??? :shock:

Pilots of the Russian Aerospace Forces have fully mastered the flight modes of Su-57 aircraft including the extreme altitude, speed and g-load.

While performing the flight tasks, pilots have worked out the individual and group piloting, group co-ordination on the flight level, low and extreme low altitude flights and also the combat use of aircraft's armament.

At the final stage of the training, the pilots practiced air-to-air combat elements involving super-maneuverable modes of the aircraft.

Su-57 is the 5th-gen fighter jet designed for engaging ground, air and naval targets. The aircraft is equipped with armament placed into internal bays, the newest onboard hardware and provided with a stealth-tech radar-absorbent coating.

Within the State Defence Procurement, Russian ASF are to receive 76 aircraft of this type.

The climbing missile shot is interesting. You can see the (archer?) peeking out of the side weapons bay, just prior to launch. So too though, were the large gaps between panels on the underside of the aircraft.

Let's assume all the weapons testing and integration is done. We'll also assume all the avionics work as advertised. They still had the first production version crash, and its still unclear as to why. Is it the flight control software? A control surface anomoly? Something else??

Good luck pumping out new production aircraft without finding and fixing that issue. I sure wouldn't want to be flying it, but I'm not so certain their pilots have a choice. They need to get 76 aircraft right, and so far I can only see problems with these prototypes featured in the video. Every time there's a setback, we get a new video of the prototypes flying around and the narrative is that full scale production is upon us.

If that's true, where are the operation units flying this thing?

I find it interesting they fitted R-74 missile in weapon pod, I thought it would need new missile (smaller then R-73/74).

Pictures are very bad, it does not show nothing more than a missile being fired, but not any evidence about if it was from internal side bay.

I am not surprised.

Really If the russians have used an air to air missile from its internal bays, we will have good pictures and videos without any doubt.

I know they're a Kremlin mouth piece, but how exactly do Russian Air Force pilots start "flying SU-57's" when.... the first production version crashed on its maiden flight? (Christmas eve, 2019).

https://militarywatchmagazine.com/artic ... e-ministry

This is getting ridiculous. Russia is putting out video/news stories to make us forget not a single production aircraft has been fielded, let alone a squadron or two of the type. So instead they give use more videos of the prototypes zipping around. Really? The accident investigation has been wrapped up and they've delivered several production aircraft since the crash? How many could that be? Two? Three? Maybe...? More like ZERO, assuming of course they don't want them crashing too.

Do they think other countries are fooled by this? For anyone who's been following the program, it's clear the SU-57 is still FAR from being ready for prime time..

I did frame by frame in vlc and missile emerging below wing and then it is fired so it is probable test fire from side weapon bay. So no fixed pylon maybe no bay doors but I really doubt that.
