In America, they named the most reliable rocket in the world in terms of the number of accident-free launches in a row
The rather popular analytical online publication Ars Technica conducted a study and found out which rocket is currently the most reliable in the world.
Of course, the Soviet-Russian carrier rockets of the Soyuz family remain the real "kings of all earth rockets" in terms of the total number of launches, but in terms of reliability they are allegedly inferior to the American Falcon 9. We will talk about how the Americans carried out the calculation in this material.
According to the Americans, the most reliable missile from America
So, the authors of the study point out that the first modifications of the Soyuz rocket went into space as early as 1957, and the rocket has undergone at least 12 modifications throughout its long history of operation.
During all this time, Soyuz were launched into space 1946 times, of which 1827 launches were successful, which means that 119 launches were unsuccessful. And in fact, this is an outstanding result.
At the same time, the modification of the Soviet Soyuz-U rocket, as well as the American Delta II, that have already been decommissioned, were named among the most reliable missiles. Both the Soviet and American rockets had 100 consecutive launches without accidents.
But according to E. Berger (Ars Technica analyst), the record for the maximum number of accident-free launches in a row has already been broken by the American Falcon 9 rocket. And according to the analyst's count, Falcon 9 has already completed more than 110 successful launches in a row.
And as E. Berger, it is noteworthy that the Falcon 9 scored this number of accident-free launches at a time when SpaceX experimented with the reuse of the returnable first stage launch vehicle.
So, on average, one first stage of the Falcon 9 rocket was used more than three times, and the maximum number of first stage launches was 11 times.
Well, these are the results for accident-free launches in a row showed an American rocket. Write in the comments, do you agree with this calculation method, or should only full-fledged launches with a real payload on board be taken into account?
