The
Boeing B-52 Stratofortress is a long-range, subsonic, jet-powered, strategic bomber flown by the United States Air Force (USAF) since 1955.
The B-52D was a dedicated long-range bomber without a reconnaissance option. The Big Belly modifications allowed the B-52D to carry heavy loads of conventional bombs for carpet bombing over Vietnam. Aircraft assigned to Vietnam were painted camouflage with black bellies to defeat searchlights.
