A B-52H Stratofortress lands at Minot Air Force Base, N.D., Apr. 2, 2015, after completing a U.S. Strategic Command-directed training mission, Polar Growl. The round-trip sortie from their home base to the North Sea region allowed the aircrews to hone their navigation skills and enhanced their ability to work with allied partners. STRATCOM is one of nine Defense Department unified combatant commands and is charged with strategic deterrence; space operations; cyberspace operations; joint electronic warfare; global strike; missile defense; intelligence, surveillance and reconnaissance; combating weapons of mass destruction; and analysis and targeting.
