The research project Public Intelligence has assembled a map and list of dozens of current and planned areas with Department of Defense drone activity, including the type of craft.  ”What exact missions are performed at those locations, however, is not clear,” Danger Room reports. “Some bases might be used as remote cockpits to control the robotic aircraft overseas, some for drone pilot training. Others may also serve as imagery analysis depots.”

Wired notes that 12 of the locations are for “Predator and Reaper unmanned aerial vehicles, which can be armed.”

Secrecy News, meantime, cites another report that lists 110 potential drone bases, vs. the 88 in the Public Intelligence report. Here’s that DOD report to Congress. (PDF)

In April, the Electronic Frontier Foundation released a similar map of public and private sector drone operations.
