THE BURNED OVER DISTRICT

National sovereignty included the airspace above your country. That appears to be going by the board now that we have all those unmanned drones that need to be used.

Since November 2011, the U.S. Air Force has been flying unarmed drones from Incirlik Air Base in Turkey in an attempt to suppress a long-simmering regional conflict. The camera-equipped Predators hover above the rugged border with Iraq and beam high-resolution imagery to the Turkish armed forces, helping them pursue PKK rebels as they slip back and forth across the mountains.

As the Obama administration dials back the number of drone attacks in Afghanistan, Pakistan and Yemen, the U.S. military is shifting its huge fleet of unmanned aircraft to other hot spots around the world. This next phase of drone warfare is focused more on spying than killing and will extend the Pentagon’s robust surveillance networks far beyond traditional, declared combat zones.

Over the past decade, the Pentagon has amassed more than 400 Predators, Reapers, Hunters, Gray Eagles and other high-altitude drones that have revolutionized counterterrorism operations. Some of the unmanned aircraft will return home with U.S. troops when they leave Afghanistan. But many of the drones will redeploy to fresh frontiers, where they will spy on a melange of armed groups, drug runners, pirates and other targets that worry U.S. officials.

Elsewhere in the Middle East, the U.S. Air Force has drone hubs in Qatar and the United Arab Emirates to conduct reconnaissance over the Persian Gulf. Twice since November, Iran has scrambled fighter jets to approach or fire on U.S. Predator drones that edged close to Iranian airspace.

In Africa, the U.S. Air Force began flying unarmed drones over the Sahara five months ago to track al-Qaeda fighters and rebels in northern Mali. The Pentagon has also set up drone bases in Ethiopia, Djibouti and Seychelles. Even so, the commander of U.S. forces in Africa told Congress in February that he needed a 15-fold increase in surveillance, reconnaissance and intelligence-gathering on the continent.

In an April speech, Deputy Defense Secretary Ashton B. Carter said the Pentagon is planning for the first time to send Reaper drones — a bigger, faster version of the Predator — to parts of Asia other than Afghanistan. He did not give details. A Defense Department spokeswoman said the military “hasn’t made any final decisions yet” but is “committed to increasing” its surveillance in Asia and the Pacific.

All your airspace R belong to us. But don't even think about overflying us.
