Which two aircraft were derived from the military An-24?

The An-24 was a 50-seat regional airliner with two turboprops, designed in 1957 in the Soviet Union by the Antonov design bureau. Its task was to replace the veteran piston-engined transport Ilyushin Il-14 on short- and medium-haul routes, with a design optimised to operate from poor-quality runways and unprepared airfields in remote locations. Antonov conceived it as the first of a future family of turboprops.

The An-26 reuses most of the An-24's airframe: a cantilever high wing and two Ivchenko AI-24 turboprops mounted on the wing. It was designed and produced in the Soviet Union between 1969 and 1986 as a regional airliner and military transport. Most of the An-26's early production went to the VTA, the Soviet military transport aviation force.

The An-32 is essentially a re-engined An-26 and the fourth member of the An-24 family. Its Ivchenko AI-20 turboprops, at 5,100 hp, deliver almost twice the power of the An-26's AI-24s. It is credited with outstanding takeoff performance in hot-and-high conditions, up to 55°C (131°F) and 4,500 m (14,800 ft) elevation. The An-30 is likewise a derivative of the An-24, in its case with a completely new forward fuselage.
