The retraction sequence of the unique main undercarriage is particularly noteworthy—the relatively substantial unit is designed to fit neatly into a limited volume of the fuselage while at the same time leaving room for the carriage of pylon-mounted stores beneath the fuselage and the wing-root glove The ground-attack MiG-23 is now operational in East Germany. The photograph above shows one of these aircraft and is reproduced from our West German contemporary "Flug Revue". The side-view drawings (right) show the three principal operational variants of the MiG-23 Flogger identified so far. At the topiis the basic intercepter, with nose radar, variable-geometry inlet and variable jetpipe. In the middle is the two-seat trainer based extensively on the intercepter and carrying air- to-air missile pylons as well as the twin-barrelled 23mm gun. At the bottom is the ground-attack variant with redesigned nose section, no radar, fixed inlet, different pylons, a Gatling-type gun and fixed jetpipe. Whether the revised inlet and exhaust are the result of a new engine being installed is not known
