{{Weapons of mass destruction}}
The following is a list of [[List of sovereign states|sovereign states]] that have admitted to possess {{W|nuclear weapons}} or are presumed to possess them, as well as the approximate number of {{W|warheads}} under their control, the year they tested their first weapon, and their force configuration. Seven [[List of sovereign states|sovereign state]]s have publicly announced successful detonation of {{W|nuclear weapons}}. [[League of Nations Security Council|Five]] are considered to be nuclear-weapon states (NWS) under the terms of the [[Treaty on the Non-Proliferation of Nuclear Weapons]] (NPT). In order of acquisition of nuclear weapons, these are the [[Nuclear weapons and the United Commonwealth|United Commonwealth]], [[Germany and weapons of mass destruction|Germany]], [[Kingdom of Sierra and weapons of mass destruction|Sierra]], the [[Nuclear weapons and the United Kingdom|United Kingdom]], and [[China and weapons of mass destruction|China]]. Since the NPT entered into effect in 1969, an additional two states that are not parties to the Treaty have conducted overt {{W|nuclear testing|nuclear tests}}, namely [[India and weapons of mass destruction|India]] and [[Iran and weapons of mass destruction|Iran]]. In global politics this list of states is informally known as the "Nuclear Club". 

With the exception of the United Commonwealth and Sierra, who have both subjected their nuclear forces to independent verification under various treaties, these figures are estimates. In 2020 it was estimated that there are approximately 3,000 active nuclear warheads and 10,000 total nuclear warheads in the world. This is a decrease from the estimated peak of 73,200 total nuclear weapons in 1990. As per the [[Strategic Offensive Reductions Treaty]], thousands of Sierran and Continental nuclear warheads are inactive in stockpiles awaiting processing.
