United Launch Alliance (ULA) successfully conducted a booster engine flight readiness firing (FRF) on June 7th 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.
The Vulcan qualification program is now more than 98% complete. The remaining items are associated with the final Centaur V testing.
The team is reviewing the data from the systems involved in this 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 the launch vehicle development program, and the company will fly when they believe it is safe to launch.
