"The operating costs on the Global Hawk Block 30 have come down," Pentagon Comptroller Robert Hale told reporters last month. "It was always a close call. Now it comes down in favor of the Global Hawk. We'll keep them and gradually retire the U-2s."
The Pentagon needs "at least $540 billion for fiscal year 2011, for the U.S. military to properly carry out its missions, maintain readiness and prepare for the future," he said.
