a ‘Deployed’ means warheads placed on missiles or located on bases with operational forces.
b These are warheads in reserve, awaiting dismantlement or that require some preparation (e.g. assembly or loading on launchers) before they become fully operationally available.
c In addition to strategic warheads, this figure includes c. 200 non-strategic (tactical) nuclear weapons deployed in Europe.
d The US Department of Defense nuclear stockpile contains c. 4900 warheads. Another c. 3100 retired warheads are scheduled to be dismantled by 2022.
e These are warheads earmarked for delivery by deployed strategic launchers (intercontinental ballistic missiles, submarine-launched ballistic missiles and long-range bombers).
f This figure up to 2000 non-strategic (tactical) nuclear weapons for use by short-range naval, air force and air defence forces. In 2010 the Russian Government declared that all tactical nuclear weapons were in storage and not deployed.
g This includes a military stockpile of c. 4500 nuclear warheads and another c. 5500 retired warheads await dismantlement.
h The nuclear stockpiles of China, India, Pakistan and Israel are not thought to be fully deployed.
i North Korea conducted nuclear test explosions in 2006 and 2009, but there is no public information to verify that it possesses operational nuclear weapons.
