ANTONOV 12BP (Cub) Antonov An-12 (NATO reporting name: Cub) is a four-engined turboprop transport aircraft designed in the Soviet Union. It is the military version of the Antonov An-10 and was made in many variants.
An-12BP An-12B fitted with the two extra underfloor tanks of the An-12P, equipped with a NAS-1B1-28 (Navigatsionnaya Avtonomnaya Sistema – self-contained navigation system) and RSKM-2 (Rahdiolokatsionnaya Sistema Kontrolya Mesta – radio co-ordinate monitoring system).
Later-production An-12BPs were built with a wider cargo door and revised cabin windows placement.
Some An-12BP aircraft were built at the factories as commercial transports with all military or sensitive equipment removed, the designation for these aircraft was unchanged. But the tail gunner’s position is still visible.
