Sukhoi T-75 LTS (CheckMate)

Interesting would be - and even more much more important - is it state-founded or only from UAC, what's the budget, is the RuAF interested or are there other nations providing founds. Otherwise it will remain simply what it is right now: A fancy mock up and excieting PR-stunt.
 
On the pilots' uniforms in the end of the extended trailer, you can notice flags of Myanmar and Malaysia.

Notice the inlet wall that would suggests there is a twin air duct behind?!!

Also noticeable is the short head clearance. I don't know how a 6ft is gona fit inside.

i believe thats the shadow of the fueselage, canopy part

I guess, this is why we see UAE citizen right from the beginning of teaser.

Russia and the UAE will develop a fifth-generation fighter jet

The new aircraft will be modeled on Russia’s fourth-generation MiG-29 jet fighter, and experts believe it will find demand on the global market.

Additionally, the character representing RuAF can be seen in the same teaser and the model of the plane was noticed on the table of the vice-PM who supervising MIC and state weapons procurement.

It seems to me that we've seen what I'm calling the lateral bay doors hanging open under their own weight. I think that the doors would be actuated open further when in use.

There are two options I suppose. The missiles are ejected from the bay, or the missiles are mounted to the door. And, I guess, there's the third option of a SRAAM on the door and a BVRAAM in the bay.

The door is quite long and the profiling of the door suggests that there is a requirement to get something about that long out of the bay. If the bay was for SRAAM and to be door mounted, I don't think the doors would have to have that long tapered forward part. I can guess that there would be another fuselage frame or reinforced point to pick up on if they'd have wanted, which means that it's there for a reason.

Yes that side bay is intriguing, but the geometry of the inlet and airframe at that point is complicated, plus the needs of the weapon release. A simple rail lunch bay for SRAAM/MRAAM would just need the side to open, but not the bottom as it does on the rear part. Maybe bot small bombs can be released, and AAMs can be rail launched from it. It does not seem trivial in any case.

It would be uncharacteristic and outright dumb to organize this fuss and then not having a basic level of approval / funding to carry the project forward. If over MAKS no customers shows serious interest, they dump the thing? There is a lot of work already invested in this design, for sure, and it has a serious potential

honestly I wonder about the politics of this..

the main reason why the UAE would want a stealth aircraft is to attack Iran and its Shiite allies
and Iran a country that Russia is generally more friendly towards
 
How much commonality do you guys reckon it has with the 57? The fins and canopy assembly look identical at a first glance.

I wouldn't be surprised if there is a flying individual showing up soon. Granted that this is a mock-up, but re-using flight tested components for a concept is often done to cut down development costs and get it airborne quickly.

From 2010 to this day I see the Russian military development is extremely tidy and well organized. Not perfect, but it respects the fundamentals of program management and strategic development. But of course, I don't have a glass ball to know what will happen exactly with the LTS, I just think it is logic to expect them to check for the water before they jump into the pool. They are not a starving nation anymore.
 
upon first glance, the landing gears look the same too

From "Checkmate" to "write another check, mate"? ;)
 
So the air channel is split... that makes the nose wheel probably quite capable of handling serious loads needed for rough landings (STOL is a claimed characteristic of the plane) and maybe even CATOBAR launch in a potential future.

There's also US and UK, so I definitely don't think we should be assuming the pilots represent nations interested in joining the project. I think it's more "the pilots of the world are going to be stunned by this".

ETA: As Myanmar's a Chinese client it gets politically interesting if Rostec are trying to court them.

I just hope this doesn't become another S-37 - looks good but ultimately gets nowhere.

S-37 was an X-plane to experiment with FSW and composites. Dunno where the misconception it's meant to be a prototype of the combat fighter-jet came from. Journalists, i guess?

Global Security's S-37 page https://www.globalsecurity.org/military/world/russia/su-47.htm
"In April 2002 the OKB Sukhoi was chosen as the system leader for the development of a new combat aircraft of the 5th Generation, with an internal designation of T-50. MiG and Sukhoi had long been in competition for the state order for the development of a fifth generation fighter jet. MiG specialists chose the 1.44 index aircraft as the prototype of the new jet, whereas Sukhoi decided to base its work on the Su-47 fighter jet. Sukhoi's Su-47 eventually won the contest. "

(Mind you there's quite a few awkward expressions and incomplete translations (eg "OKB imeni P.O. Sukhoi") in the article that make me suspect at least part of it's translated from a Russian original)

Double nose-wheel, though I can't tell if there's anywhere for a catapult bridle to attach.

That canopy bow is in a pretty unfortunate place for forward view. It would definitely benefit from a single piece canopy, though the IRST position probably explains why they didn't go for one.

A bit bigger ... I know there is a saying "beauty lies always in the eyes of the beholder" but here - and in strict to contrast to the Su-57 - I simply cannot see any beauty!

Anyway a most interesting design.

Beauty is in the balancing of design compromises in strange and new ways.

...and also in our personal subjective aesthetic biases :)

I'm pretty sure fins are much smaller, and likely also the radar. I'm not sure about the canopy. The engine would be in-common. So, definitely the same technology - but not the same production line for the most part.

My read: The aircraft is shown delivered to the UAE (whose representative doesn't look surprised), then it shows Argentina and Vietnam receiving a text and getting excited (presumably indicating there has been some interest), then it shows the rest of the world being impressed.

I knew that LERX/intake notch reminded me of something, of course it was the MiG Izdeliye 33 which had a very similar LERX notch in one of its configurations.
Click to expand...

Yup - I definitely saw some I-33, some Yak as well - definitely the culmination of thirty plus years of thoughts on Mig-21 successors (albeit now in the Mig-29 weight range). Also some McDD/Northrop/Bae JSF (as has been pointed out). Hmm... I wonder if one could lengthen it a little and had a pair of lift jets? That said, I do suspect we're past the point where these designs can just be lengthened without reworking all of the structure and much of the LO optmisations.
 
So... who about this: One R-74 class missile in each side bay. A ventral bay with two R-77 class missiles (would prefer R-37 class, but I'm not sure there is room)...

But they'll primarily pitch it to clients has also having 4xR-37 class missiles or 4x700kg class air-to-surface weapons carried by two S-70 Okhotnik that it leads into battle... 'checkmate' in terms of a chess set having multiple pieces which work together (only some of which are manned).

That is my bet on what they'll pitch.

Liking the sound of that so far Avimimus, the R-37 looks a bit big for internal carriage in the weapons bay, though it could be carried externally if stealth is not needed.

The problem with this is that while the UAE and Vietnam can probably afford a new fighter purchase, Argentina's in a prolonged financial crisis, and is more likely a customer for second-hand fighters, if anything.

No need by now for sure. But the robustness of the assembly and the underlying structure needs to be there, so that the further development is feasible.

Russians do it like that, to protect in case of a canopy loss and to make easier to manufacture the front windshield stronger than the rest. Again, they know what they do.
 
So no Elevators?
It leaves that to what, the Stabz?
They are heavily canted so..

Not only the canopy bow but the geometry of the canopy (not wind screen) that rescind abruptly where the pilot's helmeted head sits. That could make swiveling from left to right difficult with a rear view only possible when the pilot lean forward.
The seating position is also odd with the seat headrests nearly in contact with the canopy.
Once again, with helmets as they are built today for off-boresight targeting and synthetic imagery, the available space looks oddly small.
 
If the UAE is funding this, then surely the internal bays will be sized to fit whatever Western missiles they use and their local missile programmes from Halcon and Edge Group?

That's a good point, I'd really like to see someone in the cockpit with a helmet to get a better feel for the available space.
