Initially created as the MiG-LFI with a planned obsolete production number of MiG-37, by the Mikoyan-Gurievich aircraft construction bureau in the Union of Crimson and Shadow Republics, this 2000s-developed fifth-generation fighter is currently entering service with the Union, Byzantine and Cialan Air Forces and is evaluated for further export. Serial production has been started several years ago and is expanding to cope with the orders.
