Antonov An-12 Cub Crashed And Abandoned

• 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.
• An-40PLO
An anti-submarine warfare variant of the proposed An-40, to be powered by mixed-fuel engines burning kerosene and liquid hydrogen.
