nuclear strategy The explosion from the first thermonuclear weapon (hydrogen bomb), code-named Mike, which was detonated at Enewetak atoll in the Marshall Islands, November 1, 1952. The photograph was taken at an altitude of 3,600 metres (12,000 feet) 80 km (50 miles) from the detonation site.

Strategic bombers like the B-52 were central to U.S. military strategy during the Cold War as a primary component of the nuclear triad. This three-sided structure—comprising land-based missiles, submarine-launched missiles, and strategic aircraft—was designed to ensure that a nation’s nuclear forces could survive a first strike and remain capable of launching a second strike, thereby upholding the principle of mutually assured destruction.12

Operated by the Strategic Air Command, the B-52 served as a principal long-range nuclear weapons carrier for decades. Its strategic value included:34

Deterrence: As part of the "New Look" defense policy, bombers provided a visible and powerful deterrent against aggression.23
Flexibility: Unlike fixed missile silos, bombers could be dispersed to numerous domestic and overseas bases to reduce vulnerability to a surprise attack.3
Adaptability: While initially designed for high-altitude penetration, the B-52 was later upgraded to carry air-launched cruise missiles, allowing it to threaten targets from outside the range of sophisticated air-defense systems.45
