Operation Upshot-Knothole, Nuclear test series at Nevada Test Site, United States.
Operation Upshot-Knothole was a series of eleven nuclear detonations conducted at the Nevada Test Site between March and June 1953, using different delivery methods such as airdrops and tower-mounted explosions. The tests employed various techniques to gather radiation data and evaluate military strategies.
This operation marked a critical phase in Cold War nuclear development and tested the first atomic artillery piece. Roughly 18,000 Defense Department personnel gathered crucial data that shaped future military planning.
These nuclear tests shaped American military thinking and influenced how the public understood atomic weapons through televised broadcasts of specific detonations across the nation.
Military personnel observed detonations from trenches positioned at different distances to measure effects on those in proximity to blasts. Access to this historical site requires special arrangements, and the location remains under restricted conditions today.
One notable test was Grable, which fired a 280mm atomic projectile from a specialized cannon, proving nuclear artillery was practical. This test demonstrated for the first time that nuclear weapons could be deployed as portable field weapons.
