Space Rocket History #94 – Soyuz Development – Part 3

Posted on January 1, 2015 by spac9750

After Voskhod-2, an ideological vacuum, disorder, and vacillation cropped up in the Soviet maned space program. There was no clear-cut answer to which project should be the priority, a new series of Voskhods, artificial gravity experiments, or the construction of the Soyuzes. However, during August 1965 the wavering ended. First priority was given to the Soyuzes. A real all-hands rush job to develop and manufacture Soyuzes got underway. A new un-realistic schedule was created that required OKB-1 to supply, three Soyuz flight vehicles ready for testing, two in December of 1965 and one in January of 1966.

The circumlunar plan involved 3 new spacecrafts. First the Soyuz A 7K spacecraft, capable of carrying three men, (2 men for a circumlunar flight) into space and returning them to earth. The 5.5 ton spacecraft has three modules, the orbital module, the re-entry module, and the service module.

The second new spacecraft is the Soyuz B 9K booster stage, with a fueled mass of 18 tons. After docking with the 7K, the 9K is capable of boosting the combined spacecraft out of earth orbit on a course to the moon.

The third new space craft is called Soyuz V 11k tanker. It has a mass of 5 tons. It is used to ferry fuel from the earth to the 9K Booster. It will take 4 tankers to fill the 9K booster with enough fuel to push the Soyuz 7K on a path to the moon.
