The boss of US Strategic Command, Marine Corps Gen. James Cartwright acknowledges that the high-flying U-2 reconnaissance aircraft has one major drawback: its pilot. The pilot “limits the duration on station.” Having said that, Cartwright told lawmakers that its obvious replacement—the Global Hawk unmanned aerial vehicle—has “to demonstrate its capability, both in the upgrades and the numbers, before we want to let go of the U-2.” Congress last year prevented the Air Force from accelerating U-2 retirement because it perceived an intelligence-surveillance-reconnaissance gap. Cartwright admitted that USAF has to perform “a balancing act,” however he maintained, “I cannot afford a gap in capability.”
A new report from the Government Accountability Office calls for the Pentagon’s Chief Technology Officer to have budget certification authority over the military services’ research and development accounts—a move the services say would add a burdensome and unnecessary layer of bureaucracy.
