Background: In October 1951, the Cold War nuclear arms race reached pivotal technical milestones for both superpowers. On October 18, 1951, the Soviet Union successfully detonated its third atomic bomb (RDS-3/Joe-3)—a 42-kiloton composite plutonium-uranium device dropped from a Tu-4 bomber—marking the USSR's first-ever air-dropped nuclear weapon and demonstrating operational deployment capability. Just four days later, on October 22, 1951, the United States launched Operation Buster-Jangle at the Nevada Test Site with Shot "Able," a low-yield tower test designed to evaluate new lightweight implosion physics, opening a foundational test series that integrated military exercises alongside nuclear detonations to study battlefield troop tactics under real atomic conditions.
