The military is dramatically upping its investment in drones over the next nine years, according to Pentagon plans.
In the Pentagon's 30 year plan for aircraft procurement, medium and high altitude unmanned aircraft like the Global Hawk, Predator, and Reaper will balloon in number to 650 in fiscal year 2021, up from approximately 340 in fiscal year 2012.
According to the plan the spike is based on need experienced during recent military operations.
Outgoing U.S. Defense Secretary Robert Gates says NATO has become a "two-tiered" alliance poorly equipped to deal with challenges, and with members either unable or unwilling to carry out agreed missions in Afghanistan and Libya.
In his farewell speech Friday to the NATO Council in Brussels, Gates pulled few punches in listing the shortcomings of the alliance.
In particular, he drew a contrast between those members "willing and able to pay the price and bear the burdens of alliance commitments, and those who enjoy the benefits of NATO membership ... but don't want to share the risks and the costs."
"This is no longer a hypothetical worry," he said. "We are there today, and it is unacceptable."
Gates called for urgent action to "avoid the very real possibility of collective military irrelevance."
Ultimately, he said, "nations must be responsible for their fair share of the common defense."
