Action finally returned to the United Launch Alliance’s (ULA) Space Launch Complex 41 (SLC-41) as the Vulcan-Centaur rocket rolled out to the pad on May 11 for further testing ahead of its debut flight. This was followed by Flight Readiness Firing (FRF) testing that initially required a rollback before attempting again on June 7, successfully.
These events come as ULA enters the home stretch in its preparations for the inaugural launch of its Vulcan-Centaur launch vehicle. Vulcan is designed to replace both Atlas V and Delta IV Heavy, which are currently being phased out.
