Sukhoi – legendary and super agile Su-27 Flanker
While comparing Western to Eastern technology and fighter jets we cannot skip over two widely compared aircrafts: Sukhoi Su-27 “Flanker” and the McDonnell Douglas F-15 “Eagle” (now Boeing F-15 Eagle). In the eastern aviation world Sukhoi stands for a legend. The Sukhoi design bureau made such successful aircraft as the SU-24 Fencer strike fighter and the SU-27 Flanker, series of air superiority fighters. The Sukhoi Su-27 Flanker was the top of Soviet technology at the time of its debut in the mid 80′s. Large but exceptionally agile, it had powerful engines and a big load of weaponry. With the Flanker fighter jet, the Soviet aviation industry made a leap forward in military technology. The Su-27 is a really great aircraft and a huge success of Soviet aviation, not only because it holds 27 absolute records. It is an exceptionally maneuverable machine, one of the most agile aircrafts ever built. Russians proudly demonstrate it during air shows – the Russian Knights aerobatic team of the Russian Air Force performs with six Su-27.
Flanker is an extremely nimble aircraft, can be controlled even at very low speeds and high angles of attack. A Cobra (Pugachev’s Cobra) – briefly sustained level flight at a 120° angle of attack – is a dramatic and very demanding maneuver usually demonstrated by Su-27 during airshows.

Would you like to try some of those maneuvers sitting in a cockpit? Well, it’s still possible on another powerful plane MiG-29 Fulcrum. If you are interested click here to get more information.
The Russian Su-27 Flanker could easily compete with the United States Air Force F-15 Eagle. Both, the F-15 and the Su-27 Flanker were designed as powerful air superiority fighters. A Flanker performs better than the Eagle in a dogfight, but is the difference that big? Each pilot would probably share a different opinion. The F-15 Eagle is a twin-engine, all-weather, extremely maneuverable, tactical fighter aircraft designed by McDonnell Douglas (now Boeing) to gain and maintain air supremacy in aerial combat. It takes place among the most successful modern fighter jets, with over 100 aerial combat victories and no losses in dogfights. The only losses the F-15 fleet faced was due to ground fire. Here is what the F-15s killed during the Gulf War alone, according to the USAF:
- 5 MiG-29 “Fulcrum”
- 2 MiG-25 “Foxbat”
- 8 MiG-23 “Flogger”
- 2 MiG-21 “Fishbed”
- 2 Su-25 “Frogfoots”
- 4 Su-22 “Fitter”
- 1 Su-7
- 6 Mirage F1
- 1 Il-76
- 1 Pilatus PC-9 trainer
- 2 Mi-8 helicopter
The Eagle’s air superiority is achieved through a combination of superior maneuverability (low wing loading) and acceleration (high engine thrust/weight ratio), range, weapons and multimission avionics (including a head-up display, advanced radar, inertial navigation system, flight instruments, ultrahigh frequency communications, tactical navigation system, instrument landing system, an internally mounted, tactical electronic-warfare system, “identification friend or foe” system, electronic countermeasures set and a central digital computer). The F-15 is equipped with electronics and weaponry enabling the pilot to detect, acquire, track and attack enemy aircraft while operating in friendly or enemy-controlled airspace.
The Eagle would probably have an advantage at longer ranges because of its superior avionics.
The Eagle’s and Flanker’s armament comparison
The F-15 can carry a wide range of air-to-air weaponry. The Eagle can be armed with combinations of: AIM-120 advanced medium range air-to-air missiles on its lower fuselage corners, AIM-9L/M Sidewinder or AIM-120 missiles on two pylons under the wings, and an internal 20mm Gatling gun located in the right wing root.
The Sukhoi Su-27 armament includes a single 30 mm Gryazev-Shipunov GSh-30-1 cannon in the starboard wingroot, up to 10 hardpoints for missiles and other weapons. Flanker’s standard missile armament for air-to-air combat is a combination of Vympel R-73 (AA-11 Archer), Vympel R-27 (AA-10 ‘Alamo’) weapons, with extended range and IR guided models. Flanker has a comparable weapon aresenal to the Eagle in some respects.
