The Mikoyan MiG-35D (Fulcrum-F) is a Russian two-seat multirole fighter that is a further development of the MiG-29M/M2 and MiG-29K/KUB fighters. It is classified as a 4++ generation jet fighter by Mikoyan. The first prototype was a modification of the aircraft that previously served as a MiG-29M2 model demonstrator. In 2009, ten prototypes had been built for field trials.The single-seat version is designated MiG-35 and the two-seat version MiG-35D. The fighter has vastly improved avionics and weapon systems, notably the new AESA radar, precision-guided targeting capability, and the uniquely designed optical locator system (OLS), relieves the aircraft from relying on ground-controlled interception (GCI) systems and enables it to conduct independent multirole missions. The MiG-35 aircraft flight hour cost is almost 2.5 times lower than those of the MiG-29 fighter.
