Antonov An-12 Cub Crashed And Abandoned

• An-12VKP
"Zebra" (Vozdushnij Kommandnij Punkt – Airborne command post) A single Irkutsk-built An-12A (c/n 9900902) was converted into an airborne command post. Three cigar-shaped fairings were carried at the wing-tips and fin-tip, other equipment was housed in long fairings either side of the rear fuselage and a war room was situated in the pressurised fuselage. Due to the superior performance of the Ilyushin Il-22 Zebra airborne command post, the An-12VKP was not proceeded with.
• An-40
Derived directly from the An-12D, was to have been powered by four 5,500ehp AI-30 turboprop engines and four 2,550kgp (5,260 lb-st) Kolesov RD-36-35 booster/brake engines, fitted with thrust reversers, in paired nacelles between the inner and outer turboprop engines. A full-scale mock-up was completed in 1965 but the VVS selected the larger and faster Ilyushin Il-76 for production instead.
