United Launch Alliance completed a wet dress rehearsal of the Vulcan rocket and a modified Centaur V upper stage on Aug. 6 at Cape Canaveral Space Force Station’s Space Launch Complex-41, according to the company. The testing campaign specifically targeted configuration updates designed to support Amazon’s Leo constellation deployment, marking a crucial step ahead of upcoming mission integration.
Vulcan Wet Dress Rehearsal at Space Launch Complex-41
The August trial at Cape Canaveral Space Force Station subjected the heavy-lift vehicle to simulated launch-day procedures, checking propellant loading and countdown sequences. Engineers evaluated how the integrated system performs under flight-readiness conditions. According to United Launch Alliance, the exercise verified the operational readiness of both the primary booster stages and the modified upper stage.
Did you know? Wet dress rehearsals are critical pre-flight milestones where rockets are fueled on the pad just as they would be on launch day, allowing ground crews to practice emergency defueling and countdown holds.
Centaur V Modifications for Amazon Leo Constellation
The recent testing campaign focused heavily on evaluating the Centaur V upper stage adjustments made to accommodate large-scale satellite deployments. Amazon selected Vulcan to help launch its planned low Earth orbit broadband network.
Next Steps for Launch Operations at Cape Canaveral
With the wet dress rehearsal concluded, teams will review data gathered during the Aug. 6 countdown simulation before finalizing flight schedules.
