Notice: This is only a preliminary arsenal of relevant material

The data and research right now presented right here is a preliminary repertoire or relevant material. We will certainly further develop our work-related on this topic in the future (to cover the in the same information as for example our entrance on World populace Growth).

You are watching: How many nukes have been used

If you have expertise in this area and also would choose to contribute, apply here to sign up with us as a researcher.

The world’s nuclear strength have an ext than 10,000 nuclear warheads in their arsenals. These weapons have actually the volume to kill millions directly and also through their influence on agriculture have likely the potential to death billions.1

Nuclear weapons technology was emerged during the 1930s and also 1940s. The very first nuclear tools were detonated over Hiroshima and also Nagasaki in august 1945. Due to the fact that then, managing the proliferation of nuclear weapons has actually been an important issue in worldwide relations and also the 2 detonations in Japan stayed the only ever consumption in warfare

All our charts on nuclear Weapons

Stockpiles of atom weapons

One way of quantifying the proliferation the nuclear weapons is to look in ~ the stockpiles countries have. The number of states with confirmed nuclear capabilities now consists of the US, Russia, UK, France, China, India, Pakistan, Israel and also North Korea.2

This chart shows that the total variety of nuclear weapons in the world peaked in 1986. It is, however, worth remembering the the disastrous power of every nuclear warhead has actually increased significantly because the first atomic weapons offered in the 2nd World War.

Nuclear Powers

It is a typical misconception that an ext and more nations room exploring and also developing atom weapons since the second World War. As the graph demonstrates, there have been peaks in nuclear weapon advance in the past few decades. Through the so late 1980s, the variety of nations arising nuclear weapons started falling and has stayed steady due to the fact that the mid-1990s.The name in the graph represent nations arising weapons, and countries marked with “-” stand for the year in which development in that country ceased.

Data high quality & Definitions

Obtaining specific count of the atom warheads own by each nation today is difficult, due to the fact that each country controls the publicly available information relating to its nuclear capabilities for defense reasons. The data presented here is taken from the Federation of American researchers Nuclear Notebook and should it is in taken together a best-estimate of the ability of each country. In enhancement to this, Israel maintains a plan of atom ambiguity and refuses to confirm or refuse its atom capabilities.

The data ~ above nuclear weapons tests come native the Oklohoma geological Survey and can it is in considered an accurate count of nuclear weapons tests.
