Soyuz 14 (Russian: Союз 14, Union 14) was a July, 1974, crewed spaceflight to the Salyut 3 space station.

The mission was part of the Soviet Union's Almaz program to evaluate the military applications of crew spaceflight.

[5] Increased solar activity raised safety issues, but it was decided radiation levels were within safe limits, so the flight continued.

Claims were made in the aerospace press that objects were laid out at the Baikonur Cosmodrome to photograph to test a high-resolution camera system on board.

[6] Some of the experiments the Soviets described included studies of the heart and circulatory systems in orbit, studies of intracranial pressure, monitoring of blood composition, measuring of lung capacity and inhalation/exhalation rates and the testing of a water purification system which condensed moisture from the station's atmosphere.
