An Explosion Knocked Out Anduril's Rocket Motor Test Site in Mississippi

The incident could disrupt a key part of the defense company's rocket motor business, which designs and tests prototype motors for military customers. A rocket motor exploded during a test at an Anduril facility in Mississippi last Friday, marking another setback in the startup's hopes of becoming a major supplier of missile propulsion systems for the defense industry. Anduril publicly confirmed the incident after an inquiry from WIRED. No one was injured in the blast, which damaged Anduril's testing stand, the company's chief operating officer Matt Grimm said in a social media post on Tuesday hours after WIRED contacted the company about the incident. Three people familiar with Anduril's operations, who were granted anonymity to discuss a sensitive situation, tell WIRED that they can't recall another time when a similar test resulted in an explosion in the past few years, and they were unaware of what may have caused last week's mishap.
