Most consecutive successful orbital launches by a rocket model

The longest streak of orbital launches without a failure or partial failure is 120, set by the SpaceX (USA) Falcon 9 rocket between 14 January 2017 and 21 April 2022. The last failure of a Falcon 9 rocket took place on 1 September 2016, when a Falcon 9 that was scheduled to launch the Israeli AMOS-6 satellite exploded during pre-launch testing.

The closest rivals to the Falcon 9's record are the United Launch Alliance Delta II, which made 100 successful launches between May 1997 and September 2018, and the Soviet/Russian Soyuz-U, which had 92 successes between October 1983 and Feburary 1986. A higher value – 112 launches between July 1990 and May 1996 – is sometimes given for the Soyuz, but this overlooks the April 1993 failure of the Kosmos-2243 mission.

In the context of orbital launches, a partial failure is a launch that – while not a complete loss – does not achieve its stated objectives. This can mean, for example, that a satellite was deployed in an incorrect, but still usable orbit, or that not every payload in a multi-payload mission was deployed. Though strictly speaking, the loss of AMOS-6 was not a launch failure, it did result in the destruction of both rocket and payload, and is regarded as a failure by SpaceX.
