Extract from « Air Force Strategic Choices and Budget Priorities Brief at the Pentagon » on 27 January 2012.
The reality is that the Global Hawk system has proven not to be less expensive to operate than the U-2. And in many respects, the Global Hawk Block 30 system is not as capable from a sensor point of view, as is the U-2. And so we have made the choice, as the deputy secretary mentioned yesterday — cancel the Block 30 program. |
PS. « not to be less expensive » = more expensive!
