Space agencies and launch operators

Delta-V tracks 60 space agencies and launch operators, together credited with 7,529 orbital launch attempts. The busiest by all-time flight count are Soviet Space Program (2,456), United States Air Force (1,078) and SpaceX (723). 22 of them have at least one launch on the manifest right now.

Each entry below opens a flight record: total launches, successes, failures, consecutive clean flights, and whatever that operator has sitting on the pad next. Reliability figures are lifetime, not recent-form — a programme that flew badly in 1965 still carries it.

Common questions

How many space agencies and launch operators are there?
Delta-V tracks 60 launch operators — 27 national, multinational or state programmes and 33 commercial providers — covering every organisation that has flown or is preparing to fly an orbital mission.
Which launch operator has flown the most rockets?
Soviet Space Program has flown 2,456 orbital launches, more than any other operator on record.
Which launch operator is the most reliable?
Among operators with at least 50 flights, United Launch Alliance has the highest success rate at 100.0% (175 successes from 175 attempts).
How is the success rate calculated?
Success rate is successful launches divided by total launches flown, expressed as a percentage. Partial failures count against the operator. Scheduled launches are excluded because they have no outcome yet.
