Which orbital rocket model has the largest number of successful consecutive missions? Active and inactive models.

Falcon 9 just reached 77.

Delta II reached 100.

Is there any other model with a better performance?

I am asking for the first three places.

Delta II might be the first but I am interested in number 2 and 3 too.

Rockets like Long March 3B and Long March 3C are considered the same model.

Mission is not the same as launch. The Falcon 9 - Amos 6 mission exploded before flight.

If you count missions, then Falcon 9 has 77 consecutive successful missions.

If you strictly count only launches, then Falcon 9 has 86 consecutive successful launches.

Yet the majority of people mean missions when they say launches. Because the Amos 6 mission exploded before launch but still it was a planned launch which obviously failed. And I go with that

  • $\begingroup$ It looks like there are 112 consecutive successful Soyuz-U launches between 1990 Jul 11 and 1996 May 5, can anyone confirm? $\endgroup$

    $\begingroup$ @Puffin - No, I do not count them different. Long March 3B and 3C are both considered LM 3 (by me). All Falcon 9 are same model. Basically "Family Model version" is equal with "Family Model" $\endgroup$

    $\begingroup$ Are you limiting this to rockets capable of putting payloads into orbit? (As compared, e.g., to short-range military missiles, whose successful flight completion rate is probably over 99%) $\endgroup$ Jan 21 at 13:56

    $\begingroup$ Dang I forgot to mention orbital. Fixed now $\endgroup$
