Fighter and interceptor, most-produced supersonic fighter, widely exported to other air forces, originally to be based on Ye-5 but instead developed from MiG-19 variant SM-12, basis of many other variants

MiG-37 Ferret: a fictional Soviet stealth model aircraft, produced by the Testors Model Company, as a counter to the American F-19. The craft combined a faceted airframe design with cooled exhausts, and radar-absorbing skin. Purely conjectural, the design nonetheless turned out to be closer in shape to the actual F-117 Nighthawk.[4]
MiGs follow the convention of using odd numbers for fighter aircraft. However, this naming convention is maintained not directly by MiG, but by ordering institutions, such as Ministry of Defence or Council of Ministers' Military-Industrial Commission (before the dissolution of the Soviet Union). The original designations for MiG aircraft are 2- or 3-digit numbers, separated by a dot. 1.44 or 1.42 is an example of the original naming. Although the MiG-8 and MiG-110 exist, they are not fighters. The MiG-105 "Spiral" was designed as an orbital interceptor, contemporaneous with the U.S. Air Force's cancelled X-20 Dyna-Soar.
