considering it was there since the conception of the aircraft it's collaterals were certainly taken into consideration from the start

Surprising, the known video from KnAAZ made during Feb this year.

When we discussed about so called radar blocker( anti-radar grid or radial-coaxial grid) inside of the air intakes several months ago, I must admit ,I was sceptical about it.First thoughts were about possible 'air flow mass issues' inside of the air intakes.Also must admit that I hoped the real grid is there 'cause it is obvious that Su-57's air intakes are not so curved as it is supposed to. Of course must admit that I was wrong ,the grids are there.Only question is , are those grids integrated from the beginning of the serial production?

Yeah, but every time we see videos of the su-57 making that Star Wars spaceship sound it was production aircraft and the Algerian models so one could think those aircraft had the blocker installed.

They've been in place since early stages of the development process. As soon as it became clear that for the desired weapons bay parameters the serpentine intakes were not viable. Subsequently they are also featured in the patents and at the very latest in the later prototypes.

And what we've seen on the video is just one layer, it's a multilayer design.

Exactly and what we could see on Dec 2020 video ( reportage on Pervaya TV HD about the 929 GLITs) was that coaxial-radial grid inside of the '511' ( I suppose) air intake.

''Отражение электромагнитных волн РЛС в передней полусфере в основном происходит от элементов входного направляющего аппарата (ВНА), и составляет до 60% в ЭПР самолёта. S-образный канал воздухозаборника в сочетании с радиопоглощающими покрытиями обеспечивает снижение ЭПР в приосевых направлениях передней полусферы, в других — за счёт экранирования ВНА, например, специальной коаксиально-радиальной решёткой, которая может быть установлена в канал любой формы, но преимущественно находит применение в «прямых» каналах.''

''Radar electromagnetic wave reflection in the forward hemisphere occurs primarily from the inlet guide vane (IGV) elements and accounts for up to 60% of the aircraft's radar cross-section. The S-shaped air intake duct, combined with radar-absorbing coatings, reduces the radar cross-section in the axial directions of the forward hemisphere, while in other directions, it is reduced by shielding the IGV, for example, with a special coaxial-radial array, which can be installed in any duct shape but is primarily used in "straight" ducts.''

Who knows, maybe they really succeeded on what Alexander Davidenko said that forward RCS of the serial/operational Su-57 can be in the range 0.3-0.4 sqm for the irradiation in the centimetric radar bands.

The blueish grey looks brighter than on Russian models, maybe it's just the lighting though. Either way, congrats to Algeria. They now field the most capable combat aircraft in all of North Africa.

but does russia even have the M1 yet?

No, there is only Su-57 as serial/operational aircraft and they have two flying prototypes of the Su-57M ( 058 and 511 blue). Su-57E is the designation for the export variant.Designation Su-57S can be possible after official entering the service in VKS but for now it is Su-57 only.
 
That's all we can do EmoBirb is just wait and see until the official photos get released by Sukhoi themselves at one point.
 
Nice photo of the T-50-2LL.

No 46 for the composites as 'ComradeVortex' mentioned.

''Пожар может серьезно повлиять на производство планеров Су-57, ведь цех №46 является критическим для изготовления деталей из полимерных композиционных материалов.''

''The fire could seriously impact Su-57 airframe production, as workshop No. 46 is critical for the manufacture of polymer composite parts.''
 
In Komsomolsk-on-Amur, a workshop at the Yu. A. Gagarin Aviation Plant (KnAAZ) caught fire. Presumably, workshop No. 46, specializing in auxiliary units, caught fire. The plant is the only serial manufacturer of Su-35S and Su-57 fighters.@ejdailyru
В Комсомольске-на-Амуре загорелся цех на авиационном заводе имени Ю. А. Гагарина (КнААЗ). Предположительно, загорелся участок на вспомогательных узлах цеха №46. Завод является собственным серийным производителем истребителей Су-35С и Су-57.

That place seems like a nightmare place to keep secure just by looking at the amount of abandoned buildings; roads and easy and close access to the plant location. Don’t the Russians have something like Area 51 anymore?
 

"Рособоронэкспорт" заявил о росте числа зарубежных заказов на истребитель Су-57​


''Москва. 14 апреля. INTERFAX.RU - Число зарубежных заказчиков российского истребителя пятого поколения Су-57 увеличивается, заявил "Рособоронэкспорт" во вторник.

"Су-57Э вызывает большой интерес у партнеров "Рособоронэкспорта", ряд из которых уже законтрактовал российский истребитель. Список заказчиков этого самолета уверенно расширяется", - говорится в сообщении компании в связи с выставкой Defence Services Asia 2026, которая пройдет с 20 по 23 апреля в Куала-Лумпуре.

Су-57Э - экспортная версия истребителя Су-57.

Модель самолета Су-57Э станет одним из ключевых экспонатов на стенде "Рособоронэкспорта" на выставке в Куала-Лумпуре, сообщила компания.''


Rosoboronexport Announces Increase in Foreign Orders for the Su-57 Fighter

Moscow. April 14. INTERFAX.RU - The number of foreign customers for the Russian Su-57 fifth-generation fighter is growing, Rosoboronexport announced on Tuesday.

"The Su-57E is generating great interest among Rosoboronexport's partners, several of whom have already contracted for the Russian fighter. The list of customers for this aircraft is steadily expanding," the company said in a statement ahead of the Defense Services Asia 2026 exhibition, which will be held from April 20 to 23 in Kuala Lumpur.

The Su-57E is the export version of the Su-57 fighter.

A model of the Su-57E will be a key exhibit at Rosoboronexport's stand at the exhibition in Kuala Lumpur, the company announced.

Is it just me, or are the impacts of the Bologna system really becoming more and more apparent on the SPF?

Many closed cities were opened and many military towns were closed following the collapse of the USSR.
