This was the last time that the Soviet-crewed Moon landing hardware was tested in orbit, and the failure seems to have been one of the final nails in the coffin of the programme.
This word is apparently used as the name of a reactive or defensive squadron in Soviet military training, and, just like the Soyuz 5, it was constructed and its crew was trained to be the responsive (not entirely passive) or female spacecraft in its docking.
Giving military names to the spacecraft was probably a response to an appeal that the commander of the Soyuz 5 made.
Further, the word was probably chosen as it begins with a letter following that sequence starting with Antey (meaning Antaeus) and Buran (meaning Blizzard); Г (G) is the fourth letter of the Russian alphabet.
The mission objectives included:[2] Stable two-way radio communication was maintained between the spaceships and the ground stations, and TV coverage was broadcast from the ships during flight.
