Su-27
Contents
Description
Shortly after the Vietnam War, both the United States and the Soviet Union got to work on a new generation of fighter aircraft that favoured manoeuvrability and dogfight performance over top speed, after seeing how badly "missile truck" designs like the F-4 Phantom II performed against more nimble aircraft that were as much as 20 years older. In 1969, the Soviet Union received details through spies on the USAF's F-X program and the aircraft it was leading to, the F-15 Eagle. As a result, the Soviets also decided to adopt a "Heavy support" doctrine with their new generation of fighters, with a smaller amount of a larger, more powerful aircraft supporting a larger amount of smaller, cheaper "frontline" aircraft just as the US was going to do with the F-15 and F-16 respectively. The design of the heavy fighter was handed to OKB Sukhoi, which quickly produced the T-10 prototype. The T-10 had many shortcomings, and after a lot of work with TsAGI to iron out the issues, the Su-27 would take to the skies for the first time in 1977. Development would continue further, and the first true "production models" would only enter service in 1985, beginning a fruitious life in Soviet service, and later in Chinese, Ethiopian, Vietnamese, Eritrian, Indonesian, Ukranian, Kazakh, Uzbekh, and Russian service with many aircraft of the type still seeing combat today.
The Su-27 (NATO reporting name: Flanker) was introduced in Update "Air Superiority" as the top-end heavy fighter for the USSR tree, capping off the Sukhoi line and beginning its transition from high speed fighter-bombers to the venerable Flanker family. The Su-27 is a jack of all trades yet a master of almost none, and that playstyle is its strongest suite. The Flanker carries a very generous amount of air to air missiles (ten), including up to six heat-seeking missiles with HMD targeting, and four of the infamous R-27ER coupled with the strong N001 Mech radar. The Flanker's lethal missile selection allows it to dispatch distracted many enemies at safe distances, and when push comes to shove, the Flanker's inherently unstable airframe and fly-by-wire control systems allows it to perform high angle-of-attack manoeuvres and partial post-stall manoeuvres at lower speeds, including the famed Cobra manoeuvres. All in all, the Su-27 should be played as a jack of all trades, and fits best into a very aggressive playable due to its lethal missiles, great avionics and sensors, and nimble flight performance. One must, however, be aware of various enemies you can encounter in the Flanker, such as all the aircraft that carry IRCCM missiles due to the Flanker's large heat signature as a result of the two massive AL-31 engines, but also be careful of dogfighting aircraft from the F-15 Eagle family, as the Eagle's superior TWR and high-speed handling as a result of the stable airframe will give F-15 players an advantage in some scenarios.

Usage in battles
The Su-27 is a fairly all-rounded aircraft, capable of of performing both air superiority and close air support duties with the aircraft excelling at the former due to it's ability to carry a massive arsenal of close to medium range air to air missiles like the potent and reliable R-73 and the maneuvreable and high speed R-27ER, whilst for more personal and intimate encounters the Su-27 sported a potent wing root 30mm GSh-30-1 with EEGS integrated. The aircraft also has HMD (Helmet Mounted Display) intergrated allowing the pilot to designate radar lock on selected target within the HMD's cubical arc which possesses a massive gimble room, one thing to note is that IR Missile lock is intergrated into the HMD allowing the HMD to lock your R-73 SRAAMs onto your enemies without the need to point your nose to lock, this gave the Su-27 a massive advantage in dogfights especially against opponents that lacked the same technology.
For ground support duties the aircraft offers a decently diverse payload options, ranging from conventional and retarded bombs to unguided missiles which featured CCIP support, one glaring issue however is the lack of computer guided munition due to the aircraft inherent nature of being a air superiority fighter.
In Air Realistic Battles, the Su-27 is a smooth operator, with excellent roll rate and turn speed, at the start of the battle, it's recommended for the player to load the aircraft with x4 R-73 SRAAMs and x6 R-27ER MRAAMs. After taking off push for afterburner until you reached ~1200kph IAS and maintain it until contact is made, it's highly advise to stay on deck and follow the terrain to induce radar cluttering whilst en route to the combat zone, this will come in extremely handy when the opposition is field F-14A/Bs which could pop off AIM-54A/Cs Active Radar Homing (ARH) Missiles which could independently track target without the need for the Tomcat's radar constantly feeding informations back.
After making visual contact with the enemy at any altitude beyond the range of 5km+, you could attempt to aquire lock using your Radar or HMD mode and pop off a few of your R-27ER to shed some weight, note that the R-27ERs possessed IOG and DL features, the former allowed the missile to continue tracking with the last given parameters whilst the latter enables the missile to reaquire it's target after lock is regained, this allowed for some tricky plays like popping off the missile at the enemy, this will encourage them to deploy Countermeasures (CMs) expecting lock to be lost or distrupted, however with the addition of DL, lock could be reaquire and the missile will resume it's tracking unlike it's contemporary like the the AIM-7M. This potentially allow the player to catch the prey off guard thinking that they've already gotten off the R-27ER's hook. at near trea top level it's highly advise that the player use R-73s instead despite the Su-27's ability to reliably lock targets even at low altitude, it is in no way reliable enough to guide the R-27ERs lest you're flying at an even lower altitude than your enemy. If the fight devolves into an dogfights, the Su-27 are have some tricks up it's sleeves, that being the Su-27's extremely maneuverable airframe at speeds below the thresholds between ~500-700kph IAS, another thing to note is that at speeds above 1200kph IAS the vertical control surfaces will stiffen up. However if you find yourself at speeds higher than 700kph IAS, then the Su-27 has yet another toy that is yet to be unveiled, which is the addition of a massive airbreak, specifically designed to enable the aircraft to perform a tight turn even at highspeed, regardless the use of this Airbreak should be done in moderation as it bleeds the aircrafts speed at an astronomical rate which could be a double edgesword or a lifesaver depending on the scenario it's used in, this enables the Su-27 to outmaneuver even the most maneuverable jets at the Battle rating with a few exceptions like the JAS-39A/C Gripen and Mirage 4000, this allows the Su-27 to turn the table of the fight ever so slightly in it's favor, allowing the aircraft to enter it's maneuverable speed threshold which could help you get your HMD acquisition of the R-73 SRAAM on the assailant or just pepper them with your potent 30mm with the help of EEGS (Note: R-73s IRCCM uses Gatewidth Tracking which is extremely flare resistant the closer the missile gets to it's target due to the IR tracking scope narrowing post-launch, this means it's highly recommended for the pilot to launch the missile preferably from or below 1km for best effect).
Notable Opponents:
F-16A/Cs: F-16s are decently maneuverable, but what makes these aircraft deadly however is the addition of AIM-9M Missiles which they sport plenty of, these Missile ultilises a Tracking Suspension system, making it extremely hard for the Su-27 to dodge as the AIM-9M will immediately suspense lock when it detects multiple heat source whilst continuing to fly with latest parameter until it could reacquire IR tracking after there's one heat source left, one way to counter AIM-9Ms however is to sporadically flare whilst changing direction, this will cause the missile to overshoot as it's tracking shuts down whilst detecting multiple heat sources.
F-14A/Bs:F-14s are capable of launching AIM-54A/Cs as aforementioned which could be extremely infuriating to deal with, the only real counter to this is by flying flat on deck, however even the slightest mistake could resulted in you getting locked on by the AIM-54s if you don't fly close enough to the ground, however the Tomcat's combat prowess starts to diminish at closer ranges.
F-15A/Js:F-15s are perhaps one of the Su-27s greatest adversary, equal in maneuvrebility, it could pull off many tight turn just like the the Su-27 combined with it'a use of AIM-9Ms, the Eagle could easy pick off the Flanker in close range engagements so caution is advise when engaging.
JAS-39A/Cs: Engagement against the Gripen is quite tricky for the Flanker, the aircraft possess possibly superior maneuvrebility than the Flanker and Eagle in some cases, combined the the Gripen's used of liscened built AIM-9Ms under the Swedish designation of RB-74(M)s direct close in confrontation is ill-advise as most fight wouldn't end well for the Flanker.
Pros and cons
Pros:
-Execellent Accelaration and Engine power
-Great Airframe allowing for very tight turns at speeds between ~500-700kph IAS
-Featured dogfighting airbreak allowing for the execution of tight turns even at highspeeds
-Massive assortments of Air-to-Air weaponry, capable of carrying a maximum of 10 missiles
-GSh-30-1 is hardhitting and capable of incapacitating most foes with a single well landed burst
-HMD is intergrated with IR tracking support allowing R-73s to be launch from unprecedented angles
Cons:
-Massive Airframe compared to most contemporaries which makes for an easy target
-Control Surfaces Stiffens at speeds higher than 1200kph
-Flares are deployed singularly one by one
-Has a tendency to snap it's wing at high speed whilst rolling excessively
History
Describe the history of the creation and combat usage of the aircraft in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).
Media
Excellent additions to the article would be video guides, screenshots from the game, and photos.
