B-52H Stratoforess bombers sit on the flightline on Barksdale Air Force Base, La., Nov. 14. The B-52 has endured the past 60 years as one of the Air Force's most powerful bombers. The B-52 provides the backbone of the bomber force with the ability for global attack and precision engagement. Its proud history paves the way as the next generation of bombers comes online to provide a comprehensive bomber package. (U.S. Air Force photo/Airman 1st Class Andrew Moua)(RELEASED)
