Soyuz 7K-T
The second generation of the Soyuz spacecraft, the Soyuz Ferry or Soyuz 7K-T, comprised Soyuz 12 through Soyuz 40 (1973-1981). Although still using the Igla system, these had no solar panels, employing batteries. The replacement of solar panels with batteries limited it to about two days of undocked flight.
A modified version of this spacecraft flew on Soyuz 13, where instead of the docking system a large Orion 2 astrophysical camera for imaging the sky and Earth was used.
Another modification was the Soyuz 7K-T/A9 used for the flights to the military Almaz space station. This featured the ability to remote control the space station and a new parachute system and other still classified and unknown changes.
