Operation Storax was a United States nuclear test series conducted during 1962–1963 at the Nevada Test Site and related locations. The series comprised a mix of atmospheric, underground, and cratering detonations and formed part of the sequence of tests surrounding the Cold War nuclear development programs. It involved scientists and organizations from the Atomic Energy Commission, the Los Alamos National Laboratory, and the Lawrence Livermore National Laboratory, and intersected with strategic policy debates involving the Department of Defense and the Kennedy administration.

Background

Operation Storax followed Operation Nougat and preceded Operation Roller Coaster in the United States sequence of nuclear tests. The series was undertaken amidst escalating tensions exemplified by the Cuban Missile Crisis and concurrent programs such as the Vela Hotel satellite monitoring effort and the Partial Test Ban Treaty negotiations. Key institutions included the Atomic Energy Commission, Sandia National Laboratories, and contractors from General Electric and Westinghouse. Political actors involved or affected included John F. Kennedy, Robert F. Kennedy, Lyndon B. Johnson, and military planners from the Strategic Air Command and United States Army who evaluated tactical and strategic implications.

The Storax series comprised 47 known detonations conducted at the Nevada Test Site as well as associated facilities such as the Tonopah Test Range and various support bases. Test types ranged from atmospheric tower shots to underground shaft and tunnel detonations, and cratering experiments directed by the Corps of Engineers. The program integrated efforts from Los Alamos National Laboratory, Lawrence Livermore National Laboratory, Brookhaven National Laboratory, and Argonne National Laboratory for diagnostics, radiochemistry, and instrumentation. International monitoring entities such as the Soviet Union's monitoring networks and early Comprehensive Nuclear-Test-Ban Treaty advocates observed the series indirectly, while media outlets including the New York Times and Washington Post reported on public debates.

Major detonations within the series included both lower-yield tactical trials and higher-yield tests up to approximately 200 kilotons. Notable events in adjacent periods—such as detonations from Operation Dominic and earlier Operation Ivy—influenced yield scaling and design choices. Diagnostic teams from Los Alamos National Laboratory employed high-speed instrumentation similar to devices used at Operation Castle and Operation Crossroads. Yield assessments involved colleagues at Sandia National Laboratories and post-shot analysis by Lawrence Livermore National Laboratory researchers. Civil defense and emergency planning groups from Federal Civil Defense Administration archives compared results with simulations produced by experts at RAND Corporation and Aerospace Corporation.

Technical goals targeted weapons effects, cratering, and yield-to-weight optimization, with emphasis on designs pursued at Los Alamos National Laboratory and Lawrence Livermore National Laboratory. Experiments addressed blast scaling, prompt radiation, and seismic coupling monitored by US Geological Survey instruments and the Air Force Technical Applications Center. Instrumentation included radiochemical sampling by teams from Brookhaven National Laboratory and high-speed photography developed with input from Bell Telephone Laboratories. Cratering tests drew upon practices from earlier programs like Project Plowshare and involved coordination with the U.S. Army Corps of Engineers for excavation and measurement. Methodological frameworks referenced modeling from Naval Research Laboratory hydrodynamic codes and code validation from Los Alamos National Laboratory archives.

Atmospheric components of the series contributed to radiological dispersion monitored by the Public Health Service and environmental studies by Oak Ridge National Laboratory. Fallout monitoring was conducted by the Environmental Protection Agency precursor units and field teams from Brookhaven National Laboratory, with analyses communicated to policymakers including staff in the Department of State and the White House. Concerns informed subsequent health studies at National Institutes of Health and veteran exposure reviews by the Department of Veterans Affairs. Local populations near Las Vegas, Nevada and regional indigenous communities engaged with entities such as the Nevada Test Site Historical Foundation and legal advocates who cited epidemiological work performed at Johns Hopkins University and Harvard School of Public Health.

Storax occurred during a period of strategic reassessment shaped by the Cuban Missile Crisis, debates over the Partial Test Ban Treaty, and evolving doctrines within the Strategic Air Command and United States Navy nuclear forces. Policymakers including John F. Kennedy and advisers such as Robert McNamara weighed test data against arms control diplomacy with the Soviet Union and representatives like Nikita Khrushchev. Intelligence assessments from the Central Intelligence Agency and monitoring by the Arms Control and Disarmament Agency informed treaty deliberations. The series influenced subsequent treaty implementation and verification work that later underpinned efforts by organizations such as the International Atomic Energy Agency and initiatives leading toward the Comprehensive Nuclear-Test-Ban Treaty.
