NATO AWACS routinely patrol the skies during major events, including meetings of world leaders and other high-profile public events, such as international football tournaments. In support of NATO operations AWACS aircraft can be employed for a variety of tasks, such as airspace surveillance and early detection of airborne threats, providing a radar picture of ongoing activities at sea or the command and control of other NATO air assets. Currently AWACS aircraft are flying missions in support of NATO’s Assurance Measures to its Eastern Allies, of the effort to defeat ISIS as well as of Operation SEA GUARDIAN, a maritime surveillance mission in the Mediterranean to counter terrorism.
