The Boeing B-52 Stratofortress is an American military long-range heavy bomber. Entering operational service in 1955, it served in the Cold War nuclear force and later in numerous conventional campaigns. The family includes several versions, with the B-52H becoming the enduring operational model.[1][2]
Production and configuration
Boeing built 744 B-52s, with the final aircraft delivered in October 1962. The H version entered deliveries in 1961 and used eight Pratt & Whitney TF33 turbofans, whereas earlier versions such as the B-52D used J57 turbojets. Changes in engines and equipment make version identification important to the aircraft's technical history.[1][2]
The aircraft's long range is supplemented by aerial refuelling. In January 1957, three B-52Bs completed a non-stop flight around the world, demonstrating the combined reach of the bomber and tanker force.[2]
Southeast Asian combat
B-52s entered combat in Southeast Asia in June 1965. The B-52D became closely associated with conventional bombing there, using its large internal and external weapons capacity. The type operated in a very different environment from the nuclear missions that had shaped its original requirement.[2]
The museum's B-52D suffered severe surface-to-air missile damage in April 1972, was repaired and flew additional missions over North Vietnam that December. Its history documents both the aircraft's capacity to survive damage and the danger of missions against defended targets.[2]
Precision and standoff weapons
Later B-52H upgrades integrated targeting pods, improved navigation and precision weapons. The aircraft can perform conventional strategic attack, close support, interdiction and maritime missions. Cruise missiles allow weapons to be launched at a distance from defended targets, while guided bombs support other attack profiles. These changes transformed the bomber's employment without requiring a new basic airframe.[1]
