SM-12 prototypes by Mikoyan/Gurevich KB

62k drawing of three SM-12 prototypes, courtesy of Sergey Andreev

The SM-12 prototypes were a development of the MiG-19S, intended as a testbed for supersonic air intakes and (probably) a back-up for the MiG-21 program. 'Thick-leap' intake of the MiG-19 was replaced by a sharp-edged circular one with a central radar cone.

SM-12 retained guns of its predecessor. In addition, the last prototype (SM-12/3) received pair of underwing pylons to carry guided missiles.

Three built.
