United Launch Alliance

Flight record

These are launches under ULA’s own name in The Space Devs’ Launch Library. They don’t count missions or payloads. A spacecraft that flew on someone else’s rocket counts for the operator that flew it.

Operator or customer

An operator owns the rocket and runs the count, and the launch schedule filters by operator. A customer pays for the mission, supplies the payload and buys the ride. Some organisations are both. Below, ULA is counted in whichever role the current schedule gives it.

No scheduled flight names ULA with someone else flying it.

How we count it: a scheduled launch counts as a customer flight when this organisation’s name or abbreviation is in the launch name, mission name or programme, and someone else is flying it. We don’t search mission descriptions, and we only see the schedule as far as it goes, which is 2026-12-31 00:00:00Z. So treat both counts as a minimum.

About ULA

United Launch Alliance (ULA) is a joint venture of Lockheed Martin Space Systems and Boeing Defense, Space & Security. ULA was formed in December 2006 by combining the teams at these companies which provide spacecraft launch services to the government of the United States. ULA launches from both coasts of the US. They launch their Atlas V vehicle from LC-41 in Cape Canaveral and LC-3E at Vandeberg. Their Delta IV launches from LC-37 at Cape Canaveral and LC-6 at Vandenberg.

The label on each flight says how exact its launch time is. If the date is only known to the month, you’ll see the month and no countdown. A weather go-probability only shows when Launch Library has one for that flight. EveryLaunch doesn’t work it out.
