The Sukhoi Su-27 "Flanker" family is a notable example of late-Cold War Soviet aeronautical engineering, designed specifically to overcome Western fourth-generation superiority. Since its introduction in 1985, the Flanker has become classic for its "supermaneuverability"—the ability to maintain controlled flight at extreme angles of attack, famously demonstrated by the "Pugachev's Cobra" maneuver. The airframe's large size masks a surprising agility, powered by twin Saturn AL-31 engines that provide a high thrust-to-weight ratio. Over the decades, the family has expanded into a vast lineage of multirole fighters, including the tandem-seat Su-30, the carrier-borne Su-33, the "Hellduck" Su-34 strike fighter, and the highly advanced Su-35S, serving as the backbone of the Russian Aerospace Forces and numerous export partners.
