Errors by three airmen troubleshooting a nuclear missile in its launch
silo in 2014 triggered a "mishap" that damaged the missile, prompting
the Air Force to strip the airmen of their nuclear certification and
quietly launch an accident investigation, officials said Friday.
In a statement released 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 nine 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.
The Minuteman 3 is the only land-based intercontinental ballistic
missile in the nuclear force. First deployed in 1970, it long ago
exceeded its planned service life, and the Air Force is developing plans
for a replacement.
The Air Force's brief summary of the Juliet-07 mishap said the Minuteman
3 missile "became non-operational" during a diagnostic test on the
evening of May 16, 2014. The next morning a "mishap crew" chief, who was
not identified, "did not correctly adhere to technical guidance" during
troubleshooting efforts, "subsequently damaging the missile." No
further details about the damage or errors were revealed.
The investigation report summary said the actual cause of the accident,
established by "clear and convincing evidence," is classified. It said
there were four contributing factors to the accident, of which it
identified two. One was the mishap chief's failure to follow technical
guidance. The other was that the mishap chief "lacked the necessary
proficiency level" to anticipate the consequences of his actions during
the troubleshooting.
In seeming contradiction of that second point, the Air Force said in its
separate statement to the AP that the mishap team chief was properly
trained for the task he was performing. It said he and two other airmen
on his team were immediately stripped of their certification to work
with nuclear weapons. They remained decertified for "over a year," until
they were retrained and returned to nuclear duty.
Lt. Col. John Sheets, spokesman for Air Force Global Strike Command,
said it is possible that some or all of the three could still face
disciplinary action.
To prevent a recurrence of their mistake and the accident it caused, the
Air Force said it has "strengthened" technical guidance, modified
training curriculum and shared information about the conditions that led
to the mishap with other units that operate Minuteman 3 missiles.
Lt. Gen. Jack Weinstein was commander of the ICBM force at the time of
the incident. The AP requested an interview with him but the Air Force
declined to make him available. Weinstein is now the top staff officer
on nuclear matters at Air Force headquarters in the Pentagon.
When the AP inquired about the accident in December 2014, Sheets said no
details could be released until after the accident investigation board
had completed its work and presented its findings to the commander of
Global Strike Command. He assured the AP that the investigation report
would be made public, although when the AP filed a request for it in
March 2015 under the Freedom of Information Act, the Air Force denied
the request, saying the information was "exempt from mandatory
disclosure" and would be withheld from release because it consisted of
"advice, opinions, evaluations or recommendations."
Sheets later said the report was not yet complete but would be made
public as required under Air Force regulations. He subsequently amended
that, saying senior officials had decided the information was too
sensitive to release.
The Air Force's own legal office says the purpose of an accident
investigation is to provide a publicly releasable report of the facts
and the circumstances of the accident. An Air Force order dated April
14, 2015, is explicit about this.
"An accident investigation conducts a legal investigation to inquire
into all the facts and circumstances surrounding Air Force aerospace and
ground accidents to prepare a publicly releasable report" and to obtain
evidence for use in litigation and disciplinary action.
At times the Air Force has been slow to acknowledge its nuclear missteps. In 2014 then-Defense Secretary Chuck Hagel
expressed worry that personnel failures were squandering public trust
in the nuclear force. He ordered an independent review, which was
underway at the time of the Juliet-07 accident. The review team was not
told of it, however, because "the accident was going through the
investigative process" at the time, the Air Force told the AP.
The most recent previous Air Force investigation of an accident at an
ICBM launch silo was in 2008. That investigation, which was publicly
released, found that a fire in a launcher equipment room went undetected
for five days. It uncovered the remarkable fact that the Air Force was
using duct tape on cables linked to the missile.
The fire was caused by a loose electrical connection on a battery
charger that was activated when a storm knocked out the main power
source. The fire ignited a shotgun storage case, incinerated shotgun
shells, ignited and melted duct tape at the opening of the launch tube,
charred an umbilical cable in several places, and burned through wires
in a pressure monitoring cable.
