Launch from the Baikonur Cosmodrome; landing 48 km southwest of Tselinograd.

Soyuz 15 was to conduct the second phase of manned operations aboard the Salyut 3 military space station.

The spacecraft arrived at the Salyut 3 space station successfully, but the cosmonauts were unable to dock, because of a fault in the automated docking-system (Igla). The Soyuz spacecraft had no reserves or backup systems for repeated manual docking attempts, so the mission had to be abandoned. Later on the state commission discovered that the Igla docking system of the Soyuz needed serious modification. This could not be completed before Salyut 3 decayed.
