MiG 25RBK / D2K M1G-25RBS / MiG-25RBSh / D2S MIG-25RBF / B2F

These aircraft were subtypes of the MiG-25R, equipped with the next generation of reconnaissance systems, but the MiG 25RBK project had received approval at the same time as the MiG-25R The aircraft passed its combined state acceptance trials (reconnaissance and bomber mis­sions) and was produced in the Gorki factory between 1971 and 1980 The RBS variant was launched a little later, in 1965; it passed its com­bined acceptance tests and was produced between 1971 and 1977. The MiG-25RB, RBK and RBS were commissioned simultaneously.

More advanced systems were developed for the MiG-25RBS in the early 1980s After this upgrade in 1981 the MiG-25RBS was renamed MiG-25RBSh, and all of the MiG-25RBSs were gradually brought up to the RBSh standard with retrofit kits as they came in for their major overhauls. The mam difference between the MiG-25RB and the newer variants was the specialized electronic systems that replaced the cam­eras. and the modifications made to the cockpit, the power supply and the air-conditioning unit MiG-25RBFs (1981) were RBs that were updated to the RBK standard but still differed in some systems such as panoramic cameras, active and passive countermeasures and the like. The specifications and performance of those subtypes were practically identical to those of the MiG-25RB
