The Sukhoi Su-27 is a Soviet-designed twin-engine fighter family whose long-range, high-manoeuvrability air-superiority design became the foundation for the wider Flanker lineage. The initial T-10 prototypes exposed aerodynamic shortcomings that drove a substantial redesign before the production configuration entered service, while the family later expanded into two-seat training and export variants operated across several countries.
