Su-27

Also known as
  • Sukhoi Su-27
  • Flanker

The Su-27, NATO reporting name Flanker, is a Soviet-designed twin-engine air-superiority fighter built around long range, high speed, and heavy air-to-air armament. Its combat record extends from Abkhazia and the 1998 Eritrean-Ethiopian War to Angola, Tigray, and the 2014 Russia-Ukraine War, where operators used it for air superiority, air-to-air combat, and adapted strike missions that now include Western precision and anti-radiation munitions.

Adapted Western Munitions

Ukraine's wartime Su-27 force has been documented carrying or releasing several Western air-launched weapons after local integration work.

Documented Combat Use

The Su-27 record is unusually broad for an air-superiority fighter: sources document air-to-air combat, strike work, bombing, air-defense patrols, and wartime adaptation for Western precision munitions.

Developed by Sukhoi and produced in Soviet, Russian, and Georgian factories, the twin-engine subsonic jet combines a protected cockpit, internal 30 mm cannon, and multiple pylons for rockets, bombs, missiles, and adapted guided weapons, with documented use from Afghanistan and Iraq to Darfur, Syria, Nagorno-Karabakh, and Ukraine.

The family moved from license-produced J-11/J-11A aircraft into domestically upgraded J-11B, naval, trainer, J-11BG, and J-11D branches, with later versions adding Chinese avionics, WS-10-series engines, and PL-10/PL-15-class missile compatibility. Its directly documented dispute record centers on People's Liberation Army air intercepts over the South China Sea rather than a conventional shooting war.
