AL-31FP is a high temperature turbojet by-pass engine of modular design. A specific feature of AL-31FP is an axi-symmetric vectoring nozzle with a thrust vector angle of ±15° in the vertical plane providing super maneuverability of the aircraft. The vectoring nozzle control is integrated with the engine control system. AL-31FP engines ensure stable operation in all available evolutions of the aircraft in super maneuverability modes. AL-31FP engines power advanced multipurpose Su-30 MKI  fighters of the 4+ generation
