PICTURED BELOW IS THE ALLIEDSIGNAL Bendix APX-100 (V) identification-friend-or-foe (IFF) equipment fitted to Hungarian air force Mikoyan MiG-21 Fishbed, MiG-23 Flogger and Sukhoi Su-22 Fitter combat aircraft. One of the system's two antennae is visible to the rear of the MiG-21Bis cockpit (right). In the case of the MiG-21, the two control panels are "scabbed" high on either side of the already cluttered cockpit, while, in the case of the MiG-23, both panels are mounted high to the right of the radar display. Some 82 aircraft have been fitted with the Bendix equipment. Hungary also plans to fit the US IFF to its MiG-29 Fulcrum.
