The Sukhoi Su-57 is a twin-engine stealth multirole fighter aircraft developed by Sukhoi. It is the product of the PAK FA (Russian: ПАК ФА, prospective aeronautical complex of front-line aviation) programme, which was initiated in 1999 as a more modern and affordable alternative to the MFI (Mikoyan Project 1.44/1.42). Sukhoi’s internal designation for the aircraft is T-50. The Su-57 is the first aircraft in Russian military service designed with stealth technology and is intended to be the basis for a family of stealth combat aircraft.
A multirole fighter capable of aerial combat as well as ground and maritime strike, the Su-57 incorporates stealth, supermaneuverability, supercruise, integrated avionics and large payload capacity. The aircraft is expected to succeed the MiG-29 and Su-27 in the Russian military service and has also been marketed for export.
After repeated delays, the first Su-57 entered service with the Russian Aerospace Forces (VKS) in December 2020.
Origins
In 1979, the Soviet Union outlined a need for next-generation fighter aircraft intended to enter service in the 1990s. The programme became the I-90 (Russian: И-90, short for: Истребитель 1990–х годов, lit. ‘Fighter of the 1990s’) and required the fighter to be “multifunctional” (i.e. multirole) by having substantial ground attack capabilities, and would eventually replace the MiG-29 and Su-27 in frontline tactical aviation service.
Though not a participant in the MFI, Sukhoi started its own programme in 1983 to develop technologies for a next-generation fighter, eventually resulting in the forward-swept wing S-32 experimental aircraft, later redesignated S-37 and then Su-47.
Due to a lack of funds after the dissolution of the Soviet Union, the MFI was repeatedly delayed and the first flight of the MiG 1.44/1.42 prototype did not occur until 2000, nine years behind schedule.
Because of Russia’s financial difficulties, the programme aimed to rein in costs by producing a single multirole fifth-generation fighter that would replace both the Su-27 and the MiG-29. Further cost-saving measures include an intended size in between that of the Su-27 and the MiG-29 and normal takeoff weight considerably smaller than the MiG MFI’s 28.6 tonnes (63,000 lb) and the Su-47’s 26.8 tonnes (59,000 lb).
In April 2002, the Ministry of Defence selected Sukhoi over Mikoyan as the winner of the PAK FA competition and the lead design bureau of the new aircraft. In addition to the merits of the proposal, Sukhoi’s experience in the 1990s was taken into account, with the successful development of various Su-27 derivatives and numerous exports ensuring its financial stability.
Design
The Su-57 is a fifth-generation multirole fighter aircraft and the first operational stealth aircraft for the Russian armed forces. In addition to stealth, the fighter emphasizes supermaneuverability in all aircraft axes, capacious internal payload bays for multirole versatility, and advanced sensor systems such as active phased-array radar as well as the integration of these systems to achieve high levels of automation
The aircraft has a wide blended wing body fuselage with two widely spaced engines and has all-moving horizontal and vertical stabilisers, with the vertical stabilisers canted for stealth; the trapezoid wings have leading edge flaps, ailerons, and flaperons. The aircraft incorporates thrust vectoring and large leading edge root extensions that shift the aerodynamic center forward, increasing static instability and maneuverability.
Designed from the outset as a multirole aircraft, the Su-57 has substantial internal payload capacity that allows the carriage of multiple large air-to-surface ordnance. Weapons are housed in two tandem main weapons bays in the large ventral volume between the widely spaced engine nacelles and smaller side bays with bulged triangular-section fairings near the wing root.
The first aircraft in Russian military service to emphasize stealth, the Su-57 employs a variety of methods to reduce its radar signature. Similar to other stealth fighters such as the F-22, the aircraft aligns the planform edges to reduce its radar cross-section (RCS); the leading and trailing edges of the wings and control surfaces and the serrated edges of skin panels are carefully angled to reduce the number of directions the radar waves can be reflected. Weapons are carried internally in weapons bays within the airframe and antennas are recessed from the surface of the skin to preserve the aircraft’s stealthy shape, while radar absorbent material (RAM) coatings absorb radar emissions and reduce the reflection back to the source.
As with other stealth fighters, the Su-57’s low observability measures are chiefly effective against super-high-frequency (between 3 and 30 GHz) radars, usually found on other aircraft. The effects of Rayleigh scattering and resonance mean that low-frequency radars, employed by weather radars and early-warning radars are more likely to detect the Su-57 due to its size.

Lol they also joined literally every other UN nation except the US and Israel.
So the Nintendo music app thing is like a nice little micocosm example of what I hate about how liberals view the world and respond to criticism of something
Lot of people pointed out that there’s no credits for any of the people who worked on the compositions
And a lot of people have unsurprisingly jumped in to say “um ah ha… as a person working for a Japanese company/japanophile/whatever allow me to explain… you see in Japan there’s an expectation that everything belongs to the company and that’s the face of everything”
And no shit. That’s what’s being criticized. Pointing at the reality of a situation isn’t an excuse for it? But their brains never work past this point. It’s institutional and is therefore just a fact of nature, beyond reproach.
Saw this video of a woman who had a stroke and broke her ankle, was denied care by the hospital who then called the police on her and police office arrested her bc she couldn’t move (I.e. wouldn’t comply in cop world) and she died.
I’m so beyond ready for the terror. Every day this kind of political murder happens and everyone involved should die a death that has them wishing they had just got guillotined
Found out my AA sponsor is a self identified tankie today. Feels fucking great man
Whenever I feel pessimistic about people, I remember Vietnam and am brought great comfort. When reading about the history of Vietnam, the shocker for me is always that they liberated Cambodia directly after the US war failed, choosing to essentially fight the US again but with China as an adversary instead of support. People who had survived defending their homeland from war crimes like napalm and agent orange deciding to go on the offense for strangers against that with even less support than they had defending. After these people secured their own freedom from the west, when they could have just decided they want to enjoy the freedom they have now, stuck up for the right thing with no support and everything to lose.
People write stories about individuals doing the right thing against insurmountable odds, but Vietnam’s communist history feels better than any of these fictional stories. Instead of just being 1 hero with their gang, it’s thousands of working class people stepping up to be that storybook hero and even succeeding
