A KC-135 Stratotanker refuels a B-52 Stratofortress above Minnesota July 31, 2016. Four KC-135s from McConnell Air Force Base, Kan., assisted in refueling two B-52s to reach Polar Roar. Polar Roar is a mission in the Arctic Circle that demonstrates the ability to provide a flexible and vigilant long-range, global-strike capability.
