The Antonov An-70 (Ukrainian: Антонов Ан-70) is a four-engine medium-range transport aircraft, and the first aircraft to take flight powered only by propfan engines. It was developed in the late 1980s by the Antonov Design Bureau to replace the obsolete An-12 military transport aircraft. The maiden flight of the first prototype took place in December 1994 in Kyiv, now independent Ukraine. Within months the prototype had suffered a mid-air collision. A second airframe was produced to allow the flight-test programme to proceed. Both prototypes were produced by the Kyiv Aircraft Production Plant.

Following the dissolution of the Soviet Union in the early 1990s, the programme became a joint development between Russia and Ukraine. The former compounded the issue of a reduced market with its intermittent commitment to the project. Repeated attempts to start production have had limited success. Western European countries, including Germany,
at one stage assessed the aircraft for procurement, but many later decided against it.

Similar to the An-124, the An-70 design makes extensive use of titanium and composites to keep weight to a minimum and increase damage resistance. Approximately 25 percent of the airframe is made of carbon-fibre composites, which are primarily used on control surfaces and the tail assembly, while aluminium and steel alloys are used for the rest of the structure.

The prototypes had a fly-by-wire flight-control system that comprised three digital channels and six analog channels.
