Temporal classification

The submitted catalog is historical from start to finish

Every record in this dataset predates the 2IA current-observation cutoff. The section contains no fictional what-if events, no forecasts, and no probability assessments. Absence from this catalog is not proof that no later or differently classified activity occurred.

Historical records

1945-07-16–2017-09-03

All 2,058 rows predate the archive's current-observation cutoff.

Current observations

0 records

This dataset does not claim to describe present-day testing status or events after September 3, 2017.

Fictional or projected

0 records

No what-if event, prediction, forecast, or probability estimate appears in the catalog or public download.

Read the unit before the count

A catalog row is not necessarily one device

A row is a catalog record, not necessarily one device. Some salvos or national test entries may aggregate multiple devices, while two Soviet rows were split from one aggregate source entry.

Dates and times are displayed in UTC because that is how the submitted catalog normalizes them. Local civil dates can differ.

Yield values are source-reported or modeled estimates. Ranges, zero-inclusive values, and missing values must remain visibly distinct; they are not converted into false precision.

What the submitted data shows

Concentration, environment, and classification

These distributions summarize source rows. They do not rank a state, assign legal responsibility, measure human impact, or establish an individual-device total.

Source lineage

Three catalog or study families

The package preserves source labels and links from the submitted CSV. Inclusion is not independent verification, endorsement, or proof that a derivative catalog is identical to an originating institution’s records.

SIPRI-derived Nuclear Explosions, 1945-1998 table

2,050 records · 1945-07-16 through 1998-05-30 UTC

Submitted compiled derivative. Its catalog label, row structure, and links are preserved; 2IA does not treat the label as proof that every field was independently verified against an original SIPRI publication.

Johnston's Archive short-version USSR nuclear-test catalog

2 records · 1972-06-07 through 1972-06-07 UTC

Used only for two separately listed Soviet underground tests split from one aggregated submitted catalog row; record-level values remain source-bounded.

Voytan et al. 2019, Journal of Geophysical Research: Solid Earth

6 records · 2006-10-09 through 2017-09-03 UTC

Six DPRK test records derived from the submitted seismological study and linked CTBTO event references; yield ranges remain estimates rather than exact measurements.

Same-origin data export

Download the reviewed public catalog fields

The derived CSV contains the same 2,058 public records and preserves UTC dates, actor, site, class, environment, source-bounded yield fields, source identity, and row-granularity warnings. It omits raw source rows, original internal identifiers, and device-construction claims.

Truth, neutrality, and safety boundary

A historical catalog is a research starting point, not a policy position or operational manual

The package preserves source labels and links from the submitted CSV. Inclusion is not independent verification, endorsement, or proof that a derivative catalog is identical to an originating institution’s records.

The public adaptation provides historical dates, locations, classifications, and source-bounded yield estimates. It excludes device construction, weapon design, targeting, effects optimization, procurement, evasion, and operational employment guidance.

For broader strategic chronology, use World Events. For source and correction rules, read the Methodology.
