In December 2-8, 1974, in accordance with the Soviet program of joint space experiment preparation Soyuz-16 modernized spacecraft performed the flight.

In the course of the flight life support system was tested (particularly, the depressurization of the modules to 520 millimeters of mercury) as well as automatic system and several nodes of docking facilities, several methods of joint scientific experiments conducting were practiced,  assembly orbit of 225 km altitude was formed.

On July 15, 1974, at 15.20  Soyuz-19 spacecraft with the cosmonauts Alexei Leonov (commander) and Valery Kubasov (flight engineer) onboard was launched from Baikonur spaceport.
