The building destroyed by an explosion at Northrop Grumman’s Promontory, Utah, solid rocket motor complex on April 16 wasn’t directly supporting the LGM-35A Sentinel strategic missile effort, and the accident won’t delay that program or others, a company spokesperson said.

“The incident at our Utah facility on April 16 will not affect our progress on any Northrop Grumman programs,” a company spokesperson said. “Specifically, nothing produced in the building supports the Sentinel program.”

The Air Force had no comment and referred all queries about the accident to Northrop
