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 favored manouverbility and dogfight performance over top speed, after seeing how badly "missile truck" designes like the F-4 Phantom II were performing against more nimble aircraft that were as far as 20 years older. In 1969, the Soviet Union recieved 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" doctorine with their new generation of fighters, with a smaller amount of a larger, more powerful aircraft suporting 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 churned out the T-10 prototype. The T-10 had many shortcomings, and after alot of work with TsAGI to iron out the issues, the Su-27 as we know it would take to the skies for the first time in 1977. Developement would continue further, and the first true "production models" would only enter service in 1985, beginning a fruituous 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 manouvers and partial post-stall manouvers at lower speeds, including the famed Cobra manouver. All in all, the Su-27 should be played as a jack of all trades, and fits best into a very agressive playstyle 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

Suspended armament

Describe the aircraft's suspended armament: additional cannons under the wings, bombs, rockets and torpedoes. This section is especially important for bombers and attackers. If there is no suspended weaponry remove this subsection.

Usage in battles

Describe the tactics of playing in the aircraft, the features of using aircraft in a team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view, but instead, give the reader food for thought. Examine the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

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".

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.
