While the Soviet space program dominated the early space race with the first manned mission, the first two-man mission, the first spacewalk, and the first three-man mission they launched far fewer space missions than the Americans. This eventually led the Americans to overshadow the achievements of the Vostok and Voskhod missions in later Gemini and Apollo missions. The ambitious Soviet designer and engineer, Sergei Korolev, began development of the Soyuz spacecraft in 1963 towards the end of the highly successful Vostok programme.

The launch of Soyuz 1 in April 1967 began an illustrious career for the Soyuz spacecraft, which through a systems of upgrades and redesigns continues to fly today. The Soyuz 7K-OK was the finalized design earth-orbit version of the Soyuz 7K and almost ended with the tragedy of Soyuz 1 in which veteran cosmonaut, Vladimir Komarov, lost his life. However this tragedy didn’t stop the use of the Soyuz 7K-OK and continued with Soyuz 3, 4, 5, 6, 7, 8, and 9 which achieved a number of firsts in their own right including first docking of two crewed vessels and first transfer of crew between two crowed vessels.

The Sangh 7K-OKCP uses parts from TANTARES and CONTARES for a more historically accurate Sangh 7K-OK spacecraft including its original probe and drogue docking mechanism. It allows for docking missions similar to Soyuz 4/Soyuz 5 where the transfer took place through an EVA instead of the later docking tunnel. This version of the craft only differs by including a passive adapter which can be docked with my Sangh 7K-OKCA build.

It is a three-crew spacecraft capable of extended long-term missions in either LKO (Low Kerbal Orbit) or MKO (Medium Kerbal Orbit). The craft possesses two historically accurate solar wings which have been present on many Soyuz craft. It also includes a high quantity, approximately 1900 dV, worth of fuel to allow for even extreme inclination changes. I have included a number of aesthetics that function as mock ups for various aspect of the spacecraft including the Vzor periscope system. Lastly I have included a couple of forward-facing lights to help with docking operations.

The launcher is a loose adaption of the Soyuz 11A511 lifter minus the shroud and is a three-stage rocket with the booster and first stages fired together. It can make the rocket rather ungainly for some but should remain stable under most ascent conditions. The resulting combination of engines will make it a fairly vertical ascent thus I recommend caution with your angle-of-attack during the pitch procedure. The boosters should ride you out into the upper atmosphere and will then be immediately ejected upon exhaustion. The first stage will be exhausted either at the very end of your ascent or early on during the orbital burn. I have included some small separation motors to help get the first stage clear of the rest of the vehicle.

The smaller second stage will finish off the orbital burn and should have a bit of fuel left over if you want to reduce your orbital eccentricity. The second stage also has some separation motors which will probably put the spent stage into a decaying orbit.
