Soyuz 2 (Russian: Союз 2, Union 2) was an uncrewed spacecraft in the Soyuz family intended to be the target of a docking maneuver by the manned Soyuz 3 spacecraft. It was intended to be the first docking of a manned spacecraft in the Soviet space program. Although the two craft approached closely, the docking did not take place and the first successful Soviet docking of manned spacecraft took place in the joint Soyuz 4 and Soyuz 5 mission.
