Manufacturing defect blamed for Vulcan solid rocket motor anomaly

By Jeff Foust, March 12, 2025

The loss of a solid rocket motor nozzle on the second flight of United Launch Alliance's Vulcan Centaur last October was caused by a manufacturing defect that has been corrected as the company awaits certification of the vehicle by the Space Force.


The Cert-2 launch of Vulcan suffered an anomaly a little more than half a minute after its Oct. 4 liftoff when the nozzle of one of the two solid rocket strap-on boosters provided by Northrop Grumman fell off. The vehicle compensated for diminished thrust that resulted from the missing nozzle and still completed its mission.


In a March 12 media roundtable, Tory Bruno, president and chief executive of ULA, said the anomaly was traced to a "manufacturing defect" in one of the internal parts of the nozzle, an insulator. Specific details, he said, remained proprietary. Read More
