Vulcan Flight Readiness Firing Success

Cape Canaveral Space Force Station, Fla., June 7, 2023 – United Launch Alliance (ULA) successfully conducted a booster engine flight readiness firing (FRF) today at Space Launch Complex (SLC)-41 at Cape Canaveral Space Force Station, Florida. The engine start sequence began at T-4.88 seconds, the engines throttled up to the target level for two seconds and then powered down. The entire FRF lasted for six seconds.

We are more than 98% complete with the Vulcan qualification program. The remaining items are associated with the final Centaur V testing. The team is reviewing the data from the systems involved in today’s test and, in parallel, continue with the Centaur V test stand anomaly investigation. Pending the data review and the investigation results, we will develop a plan for launch. Testing is an integral part of our launch vehicle development program, and we will fly when we believe it is safe to launch.
