A 3d model of the Sukhoi SU-34.

The Su-34 had a muddied and protracted beginning. In the mid-1980s, Sukhoi began developing a new multirole tactical aircraft to replace the swing-wing Su-24, which would incorporate a host of conflicting requirements. The bureau thus selected the Su-27, which excelled in maneuverability and range, and could carry a large payload, as the basis for the new fighter. More specifically, the aircraft was developed from T10KM-2, the naval trainer derivative of the Sukhoi Su-27K. The development, known internally as T-10V, was shelved at the end of the 1980s sharing the fate of new aircraft carriers; this was the result of the political upheaval in the Soviet Union and its subsequent disintegration.
