Development

While the An-24T tactical transport had proved successful in supporting Soviet troops in austere locations, its ventral loading hatch restricted the handling of cargo, and in particular vehicles, and made it less effective than hoped in parachuting men and supplies. As a result, interest in a version with a retractable cargo ramp increased, and the Antonov design bureau decided in 1966 to begin development on the new An-26 derivative, in advance of an official order. The cargo ramp was based on that design and allowed the cargo deck to be sealed and pressurised in flight. When loading cargo, it could either be lowered to allow vehicles to be driven in, or slid beneath the aircraft's fuselage, so that cargo could be loaded straight in off a truck bed. In March 1968, the OKB received official permission to begin development. Particular attention was given to the military mission, and the majority of early An-26 production was delivered to the VTA (voyenno-transportnaya aviatsiya).

Using the majority of the An-24 airframe, it has high-set cantilevered wings, wing-mounted twin turboprops with a turbojet engine in the starboard nacelle for use as an auxiliary power unit and also for extra take-off thrust, plus long main undercarriage legs. The An-26 includ
