Sukhoi Su-57 - New General Megathread for the 1st-3rd of November 2024
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.

Husky: I'm so happy my human has come home I love them so much let me jump and run around to show them how much I care
Also Husky: lmao no I'm not coming over just because you're calling me
Used to live with 3 of em. They know what they're doing and you can't tell me otherwise. Those fuckers are smart and hide it. The ones I lived with would always be loud and goofy around us, but at night they could still silently climb up onto the kitchen counters and get into the cupboards without anyone hearing.
They're obnoxiously smart. Never get a dog smarter than you are, unless you've got twelve of them and you're going to run them at least 5 miles a day so they're too blissed out on doggy runners high to plot against you or tunnel through the drywall.
It was a full kilometer farm and then just kinda abandoned logging property for longer than you can walk after where we were. Although the puppo did move to the city with us and we adjusted the sled training we did to pulling us around town on a skateboard. Let me tell you, there is no way to feel cooler than mushing a husky through a city on a skateboard. I'd hate to say I peaked the. But unless I get another skate pup that's the reality, you can't get much cooler, pretty sure those around me would spontaneously get a motorhead song stuck in their head despite never hearing the band before.
sorry but yeah, you might have peaked then, I think that's gonna be hard to top. I have never even seen something that cool irl, let alone been something that cool.
This is definitely mine. She's smart as hell she just doesn't care to listen as much as a retriever does, so it seems like it takes longer to teach her stuff.
I've consistently heard that smarter dogs, both individuals and breeds, are significantly harder to train. They pick up the tricks very fast, but once they've mastered it then the trick no longer holds their interest so they get bored. Like with shibes and a lot of the more independent sheepdogs, yes you should train them because every dog needs training for it's own safety and wellbeing and the wellbeing of other people and animals, but with a shibe or a basenji or a corgi you're kinda of just teaching them what you want to do and hoping they also want to do that thing when you give the command.
this was my cattle dog experience
that dog was so fucking smart, he would look at planes in the sky when I pointed them out to him, even out a car window. istg he understood English.
how can the enthusiasm for the return of the human be proven except through ✨ CONSTANT MOTION ✨
Every husky knows that there's something fascinating five miles away from here and it's very important that you hook them up to a sled so they can run there at full speed, pee on it, then run home.
Many such cases
