A KC-135 Strantotanker from the 100th Air Refueling Wing refuels a B-2 Spirit from the 509th Bomb Wing in the late hours of Jan. 18, 2017, during in Libya. The B-2’s low-observability provides it greater freedom of action at high altitudes, thus increasing its range and a better field of view for the aircraft's sensors. Its unrefueled range is approximately 6,000 nautical miles.
