What is the general success rate cited for the entire Soyuz rocket system history across its thousands of missions?
Answer
Hovering high, generally cited in the high nineties (above 97%)
The overall reliability of the Soyuz rocket family is described as remarkably high, positioning it among the most dependable heavy-lift vehicles flown. When considering the entire operational history spanning decades and numerous modifications, the success rate is consistently reported to be in the high nineties. This statistical achievement means that the overwhelming majority of the thousands of missions undertaken have successfully delivered their intended payloads to the target orbit or destination, placing the success rate generally above the 97% threshold.
