The tragedy of Soyuz 11 which saw the loss of cosmonauts Georgy Dobrovolsky, Vladislav Volkov, and Viktor Patsayev required a redesign of the Soyuz spacecraft. The result was the Soyuz 7K-T used between 1973 and 1981, partly to ferry crews to the Salyut/Almaz space stations. The most significant change was a reduction of crew to 2 so that they could wear special flight suits during dangerous portions of the mission such as re-entry. Another significant change to most of the flights with the Soyuz 7K-T was the removal of its solar panels which were deemed an unnecessary danger in light of problems during the Soyuz 1 mission. It also reduced the weight and cost of the spacecraft with most Soviet mission plans now focused on using it as a ferry instead of long-term missions. This left the craft with only about 2-3 days worth of battery power and was a significant limit to most Soyuz missions which was most apparent during the Apollo-Soyuz ASTP even though that craft was fitted with solar panels.

The Sangh 7K-T is an approximation of most of the Soyuz 7K-T craft and is meant to allow as a ferry for missions to my Baruti or Pravitel stations. Since it lacks solar panels I have added some batteries from BDB giving you about 400 electric charge which should see you reach a station or other craft where it can recharge. A place of shortened antennae, much like the real life whip antennae, have been put in place and in theory given you additional communication bandwidth and range.

The launcher, a loose adaption of the Soyuz 11A511 lifter, is a three-stage rocket with the booster and first stages fired together. It may make the rocket a bit ungainly for some but it should stable under most ascent conditions. The combination is very powerful so it will be a fairly vertical ascent, I recommend being cautious with your angle-of-attack during the pitch procedure. The boosters should help get you into the upper atmosphere and then immediately ejected. The first stage will finish either somewhere at the very end of your ascent or early-on during the circularization. The much smaller second stage will complete the circularization and should have enough fuel to make last-minute orbital changes as needed. The second stage will definitely be left as orbital debris but its considerably less debris then some of my other builds.

Built in the VAB in KSP version 1.4.3.
