It's probably part of the Izd-30

Already training acrobatics with prototypes.

Gotta give it to the Russians on the dare part.

The wise, well that's an open question.

Once you get to the 11th and 12th and 13th prototype and the first few serial aircraft... there shouldn't be that many surprises left in her... they have likely tested all these manouvers and even done weapons testing so it is not a huge risk really... I mean they did take two to Syria...

Very short landing demonstration at MAKS:

I wasn't expecting this .... it's already a naval version.

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.

Did he just deploy parachutes before touchdown?

That was sweet as hell

Add a tail hook and you could land this thing on a helipad

Wonder why the video switched to low res between 5 and 40 seconds.

WOW, fantastic performance!

Still x10 WOW about the capacity to think outside the box!

It seems so easy but really it need a plane already able to decelerate at such a small speed remaining stable BEFORE deploying the chutes to allow them to deploy without the risk of being ripped off by the air flow.

About the deck use I have just a doubt about the risk that the chutes could hang the point of connection between the hull and flight dek and be ripped off... but adding a 5-10 meters long plexiglass slope in the point would solve the problem nicely.
A REAL K version would have surely some other trick added, i'm sure...thrust reverser, added air brakes and so on...

But could they do this during strong wind or strong rain ... ? To be proved.

On a carrier it could work but not safe at all.

an evential carrier version will have reinforced landing gear and tailhook, no need of using parachutes.
Its low speed handling capabilities show that it should not be to difficult to modify for it.

The only issue that would require more work would be the foldable wings, to reduce the space used on deck.

Even if they were capable to land in the space of the landing strip on kutsnetov's flight deck (deploying the shutes), I do not see the sense in operating air force versions of the Su-57(without tailhook and foldable wings) from a carrier, unless it was for an emergency.

Perhaps, as a PR spoiler they should fit one with a false tailhook.

Standard mig-35 is said to be made with a landing gear strong enough for operating on a carrier without the need for a carrier version.

This landing in the video is very close to a carrier landing because it hits the runway rather than it lands on it.

We can suppose they are thinking of making it like mig-35.

Jet used to have a way higher speed than propeller planes so they needed to have a way heavier landing gear and tailhooks and to adopt angled decks in order to perform touch and go in security, approaching the deck with a lower velocity would possibly hallow to ease such burden.
Instead of chutes you can equip carrier version with large airbrakes and thrust reverser in order to try a rolling landing instead.
On land you can use such stun when in optimal conditions and revert to normal chute deploying in otherwise.
Let's wait and see if it would end in a one at time stunt or if it will develop into a new standard.

It's been done before....came across these

Anything Russia can do America can do better....

Seems me quite different: Su-57 comes down to an high AoA and touch the ground quite violently, at the point it have to make an extensive use of the tails and ailerons, such planes seems in comparison to have a very much smooth landing.

Extreme use of the wheel brakes and tails fins which serve as airbrakes to limit landing roll. Slight compensation by one of the fin.

Good thing will be that it will only need 400m runways. Secondary airports will be smaller and in greater numbers, with many more improvised airfields available as there are much more 400m straight roads than 1km ones.

And enemy will need to destroy totally the big runways in order to stop the su-57 operating.

The enemy would run out of ordinance before taking out every 200m section of flat straight road in Russia and the problem is getting worse every day rather than better.

I rather suspect it could land on grass as well if need be... Il-76s could when under 200 tons all up weight...

Max TOW of Il-76 is well under 200 tons. I doubt Su-57 can land on grass runway, except in emergency.

Il-76TD/MD have an permissible MTOW of 210 tons. From unprepared runways it is 157,5 tons. Landing: 151,5 tons.

Unprepared doesn't necessarily means it can use grass runways. It will still need something very flat, strong enough and clean.

IMO only su-25 should be able to take off from anywhere it wants.

There are videos of Il-76 operating from grass strips.
