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.

  • Mgs2/3 are still the best games ever because you can throw directional mines at your enemy. If you're standing and use a claymore you kinda toss it on the ground, if a guard is in range it like a head level proximity grenade. I can't think of any other game that let's you throw land mines at people.

    • Goldeneye for N64 had some fun mine tricks. There's a glitch where a mine attached to a box of ammo will become invisible if the ammo is picked up.

      Stick a proximity mine on a box of ammo, quickly get that box before the mine arms, and voila, instant IRL arguments about the fairness of "proxies".

      • I was the only kid who didn't have goldeneye who had an n64 at the time. For a while fps games just felt duper disorienting and it probably didn't help I was always playing multi-player with kids who ow.we the game. I eventually adjusted but it took time.

      • stacking remote mines until the stack became too large to render and disappeared lel

    • I wish Konami gave Kojima unlimited time and resources for MGS5. It was already a S-tier game from the goofy way you'd tie balloons to people to kidnap them and add them to your base.

      • The bits and pieces were all there but they weren't brought together and the game got repetive real fast. And I loved peace walker. Also, I fucking hate the story of mgs5 almost as much as 4. Ground Zeroes was a good start. It should have been grim. Big Boss was already a child solider recruiting warlord who equipped a politically unaligned group of kidnapped mercenaries with a nuke and a gundam yo deliver it. Mgs5 did everything it could to make him sympathetic where if the game was to mean anything it should be finally destroying any good will ayers had towards big boss from mgs3. He was a monster. It should have been like listening to Blowback kinda feeling game and while ground zeroes delivered what I was kinda hoping for, it pulled it's rocket punches so much it defeated its own purpose and kinds ruined the overall story again, just like 4. Mgs to me is the first 3 games and I guess peace walker but that requires accepting mgs4. Ilm just go with the classic 3
