WASHINGTON—Officials say errors by three airmen troubleshooting a nuclear missile in its launch silo in 2014 caused a “mishap” that damaged the missile, prompting the Air Force to strip the service members of their nuclear certification and quietly launch an accident investigation.
In a statement released Friday to The Associated Press, the Air Force declined to provide key additional details or a copy of the report produced last November by the Accident Investigation Board, saying the information was classified and too sensitive to be made public.
Under the Air Force’s own regulations, Accident Investigation Board reports are supposed to be made public. The Air Force did release a brief summary to the AP after it repeatedly sought answers for more than a year. The summary said the full report was classified on Nov. 9, 2015, by Gen. Robin Rand, who took over as commander of Air Force Global Strike Command in July 2015.
The Air Force said the accident caused no injuries and posed no risk to public safety. It said top Pentagon officials were briefed on the results of the investigation in December, as were members of Congress.
The damaged missile was removed from its underground silo, which is designated Juliet-07 and situated among wheat fields and wind turbines about 9 miles west of Peetz, Colorado. The silo, one of 10 in a cluster, or flight, that straddles the Colorado-Nebraska border, is controlled by launch officers of the 320th Missile Squadron and administered by the 90th Missile Wing at F.E. Warren Air Force Base in Wyoming.
The accident follows a period of turmoil inside the nuclear missile corps that the AP revealed in a series of articles and amid an emerging national debate about the costs and benefits of investing hundreds of billions of dollars to modernize the entire strategic nuclear force at a time when war craft is changing.
