United Launch Alliance

Flight record

Counts are launches filed under ULA’s own name in The Space Devs’ Launch Library register. They are not a count of missions or payloads: a spacecraft that flew on a contracted vehicle is credited to the operator that flew it.

Who flies for them, and who they fly for

An operator owns the rocket and runs the count, and it is the operator’s name the launch schedule filters by. A customer funds the mission, supplies the payload and buys the ride. Plenty of organisations are both. ULA is counted below in whichever role the current manifest actually gives it.

No scheduled flight in the current window names ULA while being operated by somebody else.

How this is counted: a scheduled launch is treated as a customer flight when this organisation’s name or abbreviation appears in the launch name, mission name or programme and somebody else is flying it. Mission descriptions are not searched, and the window is one batch of the next launches worldwide, reaching to 2026-12-31 00:00:00Z — so both counts are a floor, not a complete manifest.

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.

“T-0 known to” is the register’s own precision on the launch time — a date good only to the month is shown as such rather than counted down as if it were exact. A go-probability appears only where the operator published one for that flight; Delta-V does not calculate it and it is not a forecast made here.

Common questions

How many launches has United Launch Alliance flown?

United Launch Alliance has 175 launches on record under its own name, of which 175 succeeded and 0 failed. The register counts launches flown under an operator's own name, not missions or payloads it contributed to.

What is United Launch Alliance's success rate?

United Launch Alliance has a lifetime launch success rate of 100.0%, calculated as 175 successful flights out of 175 attempts. Its current run is 175 consecutive successes.

When is United Launch Alliance's next launch?

United Launch Alliance's next launch inside Delta-V's manifest window is Vulcan VC6L | Amazon Leo (LV-01), scheduled for 2026-10-29 00:00:00Z from Space Launch Complex 41. The register files that time with a precision of DAY. A launch time is a no-earlier-than target and can move.

Does United Launch Alliance fly its own rockets, or buy launches from another operator?

United Launch Alliance has 175 launches flown under its own name in the launch register. It is the operator on 2 flights in the current manifest window. An operator owns the rocket and runs the count; a customer funds the mission, supplies the payload and buys the ride. The operator filter on the launch schedule lists only the former, which is why a well-known agency can be central to a flight and still not appear on it.

Where is United Launch Alliance based?

United Launch Alliance is based in United States of America and the register classifies it as a commercial operator. It was founded in 2006.
