BBC News reports the U.S. has announced it will begin allowing sales of armed drones to some friendly and allied countries. Only the U.K. has been allowed to purchase armed unmanned aircraft. Other countries have unarmed craft. Countries purchasing drones must sign agreements they will only be used for military campaigns and the U.S. will review how the country is complying. The change comes amid China exporting drones from its own unmanned program to at least nine countries. In the newly published policy, the state department did not specify which countries would be considered for armed drone sales, but unnamed officials told U.S. media previous requests by Italy and Turkey would be reconsidered. U.S. lawmakers are also currently considering selling unarmed Predator drones to the United Arab Emirates.
