The Mikoyan MiG-35 (Russian: Микоян МиГ-35, NATO reporting name "Fulcrum-F") is a mature evelopment of the MiG-29M/M2 and MiG-29K/KUB technology. Classified as a 4.5 generation fighter aircraft, the only existing prototype is the third modification of the existing MiG-29M2 airframe which previously served as MiG-29M2 model demonstrator. The MiG-35 is now classed as a medium-weight aircraft because its maximum take-off weight has increased by 30 percent which exceeds its previous criteria of classification.
