This landing page features a series of Commons Library briefings on the policies, capabilities and programmes of the nuclear weapon states. They should be taken as correct at the time of writing, and will be updated periodically.
There are nine countries in the world that possess nuclear weapons. Between them they hold an estimated 12,705 nuclear warheads, 9,440 of which are thought to be operational.
The House of Commons Library has written a series of papers that briefly examine the nuclear policies, capabilities and modernisation programmes of the nine nuclear weapon states.
Transparency is a major challenge, however. Even in the most open of democracies nuclear weapons programmes are largely classified. Information is not widely available and, for those countries motivated either by threat perception or conventional military inferiority, the tendency to exaggerate the extent, or operational nature, of their nuclear arsenals is commonplace.
As a result, there can be significant disparity in the estimates of each state’s active arsenal, reserve stockpiles of operational warheads and those warheads awaiting dismantlement. Information on spending related to nuclear weapons can also be limited. This lack of openness is a particular difficulty in relation to those states that operate outside the framework of the Nuclear Non-Proliferation Treaty (NPT) and the International Atomic Energy Agency.

Over the years various states have been identified as nuclear threshold states, either by default because of the sophistication of their civilian nuclear programmes, or because of their nuclear weapon aspirations.
This series of papers does not examine those countries with a latent nuclear capability. However, they continue to have relevance to the overall nuclear debate.
