A MiG-23 “Flogger” at the Deutsches Museum / Air and Space Museum, Schleissheim:
The MiG-23 “Flogger” was developed by the USSR in the late 1960’s and early 1970’s to counter western aircraft like the F-4 Phantom II. You can’t tell from this image, but the Flogger has variable-geometry wings, in order to reduce what would otherwise be very long runway requirements. The target of a long series of upgrades, this design was not substantially surpassed in the west until the advent of the F-15 and F-16 in the mid- to late-1970’s.
Over 5,000 copies of the MiG-23 were built in a variety of variants, and it still remains in somewhat limited service in a handful of client states — mainly in the Middle East.
