Space agencies and launch operators

EveryLaunch tracks 107 space agencies and launch operators. Between them they've made 7,669 launch attempts. The busiest are Soviet Space Program (2,456), United States Air Force (1,078) and SpaceX (744). 38 of them have a launch on the schedule right now.

This list has two kinds of organisation in it. An operator owns the rocket and runs the count, and the launch schedule filters by operator. An agency or customer pays for the mission and supplies the payload, then buys the ride from an operator. So an organisation can own a mission and still not show up in that filter. NASA and ESA work that way, and both are in the list below with a full flight record.

Tap any entry for its flight record. You get total launches, successes, failures, the current run of clean flights, and the next launch it has scheduled. The figures cover every flight ever, so a programme that flew badly in 1965 still carries it.

Each row shows the organisation’s type as Launch Library lists it, and how many launches it has ever attempted. The type doesn’t tell you who flies. Some state programmes fly their own rockets and others buy launches from a company. The full list, ranked by flights, is below.

Every tracked agency and operator

Operators and customer agencies together, ordered by flights flown. An organisation that mostly buys launches sits lower than one that flies them. The colour on the success rate is a band: cyan is 95% or better, amber is 80 to 95, and red is below 80.

Scope: the 107 organisations in Launch Library 2 that have flown a launch or have one filed. Ones with neither aren't listed.

Common questions

How many space agencies and launch operators are there?
EveryLaunch tracks 107. 41 are national, multinational or state programmes and 66 are commercial. They're the organisations in The Space Devs' Launch Library that have flown a launch or have one filed.
Why are NASA and ESA not in the operator filter on the launch page?
That filter lists the operator flying each mission, meaning whoever owns the rocket and runs the count. NASA and ESA fund missions and supply payloads, and these days they usually buy the launch from an operator such as SpaceX, United Launch Alliance or Arianespace. So they often won't show up on the schedule at all. You'll find them on this page instead, with a full flight record.
Which launch operator has flown the most rockets?
Soviet Space Program has flown 2,456 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?
It's successful launches divided by total launches flown, as a percentage. Partial failures count against the operator. Scheduled launches don't count, because they haven't happened yet.
