For 70 years, the B-52 Superfortress has been a symbol of American air power. In Vietnamese museums today, visitors can see American-made weapons on display, including B-52 wreckage and Soviet gear used against them. A notable claim in these museums is that a MiG-21 "Fishbed" fighter jet shot down a B-52 over North Vietnam. If true, it would be the only instance of a B-52 being downed in an air-to-air engagement.
According to U.S. sources, the Air Force lost 31 B-52s over Southeast Asia, mostly in Vietnam. This includes 18 losses due to surface-to-air missiles (SAMs) or ground fire and 13 non-combat losses. During Operation Linebacker II in December 1972, half of these losses occurred with Vietnam claiming to have shot down 34 B-52s during this operation alone.
Operation Linebacker II saw around 200 B-52s deployed for massive raids on Hanoi as the United States sought to end its involvement in the Vietnam War. Despite the heavy bombing campaign, Saigon fell three years later.
