A U.S. Air Force B-52H Stratofortress leads a flight of four Swedish JAS-39 Gripens June 11, 2015, during a Baltic Operations 2015 mission over the Baltic Sea. The aircraft took part in multiple missions throughout the exercise, including Mk-62 Quickstrike mine drops and naval support functions. During this part of the exercise, the two airframes practiced aircraft intercepts and formation flights to hone skills between pilots from different countries. (Swedish Armed Forces courtesy photo)
