WASHINGTON — The general who commands the nation’s nuclear forces said Thursday he has ordered further review of failings discovered among Air Force officers who operate nuclear missiles. But he told Congress he was not alarmed by their shortcomings.
General Robert Kehler, commander of US Strategic Command, told a House Armed Services panel that the Air Force assured him it is searching for root causes of the problem among missile launch officers at Minot Air Force Base, N.D.
‘‘As I sit here today, I don’t see anything that would cause me to lose confidence’’ in their ability to perform their mission, Kehler said.
The Associated Press reported Wednesday that a March inspection of the 91st Missile Wing at Minot gave the missile crews the equivalent of a ‘‘D’’ grade in missile operations, leading to the removal of 17 officers from duty.
Kehler said he has told the Strategic Command’s inspector general to review the results of the Minot inspection, which was performed by the Air Force Global Strike Command. That command is responsible for the missile unit’s training and readiness but would cede responsibility for them to Strategic Command in time of war.
Kehler said ‘‘the Air Force is digging into this,’’ and that his command’s inspector general will review the previous inspection’s results as well as the responses to it by commanders at Minot.
‘‘This has my personal attention,’’ Kehler said.
At a separate House Appropriations Committee hearing Thursday, the Air Force chief of staff, General Mark Welsh, found himself on the defensive over the Minot issue.
Representative Rodney Frelinghuysen, a New Jersey Republican, told Welsh that if the Minot problem had happened in the Navy’s nuclear force, the individuals involved would have been dismissed. Welsh said Minot commanders were ‘‘concerned they were not taking the job seriously enough.’’
Kehler’s comments stood in contrast to the tone of a confidential e-mail obtained by the Associated Press in which an officer at Minot sketched a picture of a troubled nuclear unit.
‘‘We are, in fact, in a crisis right now,’’ Lieutenant Colonel Jay Folds, a deputy commander at Minot, told subordinates in the April 12 e-mail. His group is responsible for Minuteman 3 missile launch crews at Minot.
In the e-mail, Folds lamented the poor reviews the launch officers received. Their missile launch skills were rated ‘‘marginal,’’ which the Air Force said was the equivalent of a ‘‘D’’ grade.
Welsh said on Wednesday that the problem does not suggest a lack of proper control over the nuclear missiles but rather was a symptom of turmoil in the ranks.
‘‘The idea that we have people not performing to the standard we expect will never be good and we won’t tolerate it,’’ Welsh said when questioned about the problem at a congressional hearing on budget issues.
Underlying the Minot situation is a sense among some that the Air Force’s nuclear mission is a dying field, as the government considers further reducing the size of the US arsenal.
Welsh noted that because there are a limited number of command positions to which missile launch officers can aspire within the nuclear force, those officers tend to believe they have no future.
‘‘That’s actually not the case, but that’s the view when you’re in the operational force,’’ Welsh said. ‘‘We have to deal with that.’’
