Nuclear weapons testing/warhead stockpile data since 1945.
Data is from armscontrol.org, ourworldindata.org, and wikipedia.org.
Made with matplotlib in python.
Yields for nuclear tests are self reported from governments/estimates from other countries. A very small number of nuclear tests have been conducted underwater or in the upper atmosphere, these are considered atmospheric tests.

“Notable Nuclear *Tests*”

As of early 2026, the United States has accused China of conducting secret, low-yield nuclear tests at its Lop Nur test site in violation of the “zero-yield” Comprehensive Nuclear-Test-Ban Treaty (CTBT). U.S. officials alleged a test occurred on June 22, 2020, and that China uses methods like “decoupling” to hide blast activity. China has dismissed these allegations as groundless.
I really wonder what were the purpose of so many “test”… only power show or there were really something technical to test?
Interesting to note that the country that the USA has nuked the most, by far, is the USA.
