The Americans had beaten the Soviets to the moon while the Soviet lunar program had completely collapsed by 1975. However the Soviets far exceeded Americans effort when it came to space stations and by 1975 had their fourth successful station, Salyut 4, in orbit and by July 1975 it was also actively crewed. A thawing in Soviet-American relations during the mid-70s afforded a cooperative opportunity which initially was going to be a visit to Salyut 4 by an American crew but changed to the Americans using their last Apollo spacecraft to dock with a Soyuz spacecraft, known as the Apollo Soyuz Test Project.

It was a meeting of a number of famous space race personalities including Deke Slayton, Tom Stafford, Alexy Leonov, and Valeri Kubasov. It was made possible by the ASTP Docking Module which provided a passive docking adapter for the Apollo spacecraft and a jointly developed androgynous docking adapter for the Soyuz. A special Soyuz variant was made for this mission, with its backup used for a solo science mission, that added a number of features that would eventually be incorporated into their main Soyuz fleet. New solar panels and thrusters were added along with the removal of the Igla equipment as the docking didn’t use the probe and drogue system.

The Sangh 7K-TM is my build of the Soyuz 7K-TM although due to a limit in historical parts available I had to make very general approximations of the antennae. The international docking adapter is used to stand in for the APAS-74 docking equipment and is present on both the Sangh and the docking module which is carried by the Kane spacecraft. I have also included some a historical navigation lights which were otherwise present on the historical vehicle in some form. The extra batteries have been kept on this model but solar panels have also been added for extra-long rendezvous missions.

The docking procedure is a bit different as the interlocking style adapter requires the craft to be oriented slightly off from each other. This allows the teeth to interlock which isn’t necessary on most other kinds of docking systems. The different antennae represent the variety of antennae required to communicate with the Apollo crew and the docking module’s docking radar system.

The lifter is the standard R7 lifter modified from the Tantares craft files and flies exactly like the rest of my Sangh craft that use the same lifter. The first and booster stages are fired together with the boosters being ejected somewhere in the upper atmosphere, or where they have exhausted. The first stage continues most, if not all, of the ascent process with the second stage taking over to finish the ascent, if necessary, and to handle orbital circularization.

Built in the VAB in KSP version 1.4.3.
