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.

Offensive armament
The Su-27 is armed with:
- 1 x 30 mm GSh-30-1 cannon, wing root-mounted (150 rpg)
- 96 x large calibre countermeasures
The Su-27 uses the same 30 mm autocannon as the MiG-29 with the same limited ammunition count of 150 rounds. Although it is not as forgiving as the American M61 Vulcan and demands precision, it has no spool up time and will deal heavy damage to any aircraft it hits. Something to note is that the Su-27's cannon is mounted on the right side of the fuselage, whereas the MiG-29's mount is on the left.

The Su-27 has a fairly wide arsenal. The air-to-air armaments are generally similar to the MiG-29SMT, with highly agile R-73 IR missiles for short-range combat and various marks of R-27 missiles for medium to long range engagements. However it has a large advantage in capacity over the MiG-29; a full air superiority loadout consists of four R-73s and up to six R-27s, which makes it an excellent missile truck for BVR jousting.
The extended-range R-27ER and R-27ET are the most capable members of the R-27 family and should be used once unlocked. The R-27ET (and its less advanced R-27T) can only be mounted on the inboard wing pylons for a maximum capacity of two, but this is sufficient for a couple of long-range sneak attacks to round out the Su-27's engagement capabilities. The inboard pylons can also mount R-73s instead for pilots who want to bring as many dogfight missiles as possible.
The Su-27 is limited to only unguided bombs and rockets for ground attack, so unlike the MiG-29SMT it cannot use TV-guided missile or bombs for standoff engagements. One notable feature is that it can carry up to four S-25O heavy bunker-buster rockets made famous by the Su-25, which can be a fun surprise for combined battles when enemy SAMs are suppressed or confused. All rockets are mounted in double racks on the inboard pylons, leaving the other pylons available for R-73s, R-27s, or bombs in a multirole loadout.
Usage in battles
Created as as fighter to combat the F-15 Eagle, this aircraft can equip up to 6x R-27 SARH missiles, which are famous for being extremely effective. Along with this, a new, capable radar lets the Su-27 engage in BVR fights better than any soviet fighter before it.
Not only that, but you get access to the R-73, a 40G missile that is feared among oponnents for being unpredictable, and precise. You can use this missile to engage targets at close range, and if the fight transitions into a dogfight, do not worry. Although it's big, and mounts a lot of missiles, it's not slow or bulky. In fact, it's the opposite, as this aircraft can engage in short dogfights in a way never seen before: The Su-27 can pull extreme AOA without problems.
Even if you're struggling to get on the tail of the enemy, you can simply lead your nose with no problem even if it seems impossible to do so, allowing for quick usage of a dogfight missile (R-73).
However, watch out: The Gripen, F-16 and even the MiG-29 will almost always outturn you, so if you're in a fight with any of them, and the dogfight starts getting too long, you'll have to start considering retreating from the fight.
Pros and cons
Summarise and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in the bulleted list. Try not to use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - use substitutions with softer forms such as "inadequate" and "effective".
Pros:
- Can carry up to 10 powerful missiles, getting access both to the R-73 and R-27
- Capable of extreme maneuvers, due to the AOA tolerance
- Can stay in the air for a long time, thanks to the huge fuel load
Cons:
- Although it pulls extreme AOA, it can't stay in dogfights for too long
- The SPO-15 RWR doesn't provide information about the exact vehicle
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.
