Defense Secretary Leon Panetta testifies on the attack on U.S facilities in Benghazi, Libya before the Senate Armed Services Committee Feb. 7, 2013 in Washington, D.C.:
"Panetta explained that “armed UAVs (unmanned aerial vehicles, or drones), AC-130 gunships, or fixed-wing fighters with the associated tanking – you’ve got to provide air re-fueling-- armaments – you’ve got to arm all the weapons before you put the on the planes” -- were not in the vicinity of Libya.
He said that even if he had been able to deploy F-16 fighters or AC-130 gunships over Benghazi in time, “the mission still depends on accurate information about what targets they’re supposed to hit. And we had no forward air controllers there” and no communications with US personnel on the ground.
He said, “because of the distance, it would have taken at least 9 to 12 hours, if not more, to deploy these forces to Benghazi. This was, pure and simple, -- in the absence as I said of any kind of advance warning -- a problem of distance and time.”
He explained that “unfortunately there were no specific indications of an imminent attack on U.S. facilities in Benghazi. Without adequate warning, there was not enough time given the speed of the attack for armed military assets to respond.”
He said there were two short-duration attacks that occurred six hours apart. “We were not dealing with a prolonged or continuous assault which could have been brought to an end by a U.S. military response,” Panetta said"
