Which countries possess nuclear weapons in 2026 – and exactly what is in their stockpiles? Read on for the complete list.
As tensions in the Middle East between the US-Israel alliance and Iran escalate daily, the genuine possibility of nuclear conflict weighs heavily on people’s minds.
Other ongoing conflicts including the Russia-Ukraine war, the Israel-Hamas confrontation, and military hostilities between Pakistan and Afghanistan create a volatile mix of dangerous military operations between nations where at least one side possesses nuclear capabilities.
In an era where knowledge is crucial, staying abreast of current developments is essential. So, for those wondering which nations possess exactly what nuclear arsenal, we’ve compiled the complete breakdown for you, reports the Express.

Russia
United States
China

North Korea
What nuclear arsenal do these 9 nations hold
These nine nuclear-armed states possess an estimated 12,300 warheads collectively as of early 2026, with over 9,614 held in operational military stockpiles for deployment via missiles, ships, aircraft, and submarines according to the Federation of American Scientists’ (FAS) 2025 Status of World Nuclear Forces.
The remaining warheads have been decommissioned but remain largely intact whilst awaiting dismantlement. According to the Federation of American Scientists: “Of the 9,614 warheads in the military stockpiles, some 3,912 are deployed with operational forces (on missiles or bomber bases). Of those, approximately 2,100 US, Russian, British, and French warheads are on high alert, ready for use on short notice.”
This overall figure of 12,241 warheads represents a substantial decrease from the roughly 70,000 warheads held by nuclear-armed nations during the Cold War. However, the total is anticipated to increase steadily throughout the coming decade, with modern weapons being far more advanced than their Cold War predecessors.
Which country possesses exactly what
The precise number of nuclear weapons held by individual nations remains a tightly-guarded state secret, meaning these estimates carry “significant uncertainty” according to the FAS. These figures are also thought to have been compiled before the escalation of tensions involving the US-Israel and Iran conflict.
That said, Russia is believed to possess around 5,459 nuclear warheads, with 1,150 classified as retired – meaning they’ve been removed from the military stockpile but remain intact whilst awaiting dismantlement.
A further 2,591 nuclear warheads sit within the Kremlin’s military stockpile, indicating they’re earmarked for potential military deployment, whilst 1,718 are already strategically positioned – bringing the active nuclear arsenal total to 4,309.
The United States, on the other hand, maintains a total active arsenal of 3,700 nuclear warheads, with 1,670 strategically deployed, 100 non-strategically deployed, and 1,930 held in the military stockpile for potential deployment.
The US additionally holds 1,477 retired nuclear warheads – bringing their total nuclear warheads to 5,177. American nuclear weapons are stationed in five other countries – Turkey, Italy, Belgium, Germany and the Netherlands – as well as on home soil.
Combined, Russia and the United States hold an estimated 87% of the world’s entire inventory of nuclear weapons as of early 2026, and 83% of the stockpiled warheads available for military deployment.
No other nuclear-armed nations apart from Russia and the US currently deem it necessary to maintain more than a few hundred nuclear weapons for their national defence, though many are developing their nuclear capabilities and gradually expanding their arsenals.
China’s overall nuclear inventory is thought to total 600, comprising 576 warheads in reserve stockpile and 24 strategically deployed. It should be noted that most of the nine nuclear-armed nations offer little or no transparency regarding the true scale of their nuclear stockpiles.
France is believed to maintain an active stockpile of around 300 nuclear warheads as of 2026, with 280 strategically deployed, 10 held in reserve and 80 retired, bringing the overall estimated total to 370.
The United Kingdom is thought to possess a total nuclear arsenal of 225 warheads, of which 120 are strategically deployed whilst 105 remain in the reserve stockpile for potential military deployment.
India, Pakistan and Israel never signed up to the Non-Proliferation Treaty (NPT), whose aim is stated as: “Prevent the spread of nuclear weapons and weapons technology, to promote cooperation in the peaceful uses of nuclear energy and to further the goal of achieving nuclear disarmament and general and complete disarmament.”
North Korea, however, initially became a signatory to the NPT as a non-nuclear weapon state, before announcing its withdrawal from the treaty in 2003.
India is estimated to possess roughly 180 nuclear warheads, Pakistan holds 170, and North Korea has approximately 50. These figures are based on the quantity of fissile material – highly enriched plutonium and uranium – that each of these nuclear-armed nations is estimated to have produced.
The precise warhead totals for Israel and North Korea remain unconfirmed, though it is believed North Korea holds sufficient fissile material to construct at least “40-50 individual weapons”, whilst Israel has the “nuclear material for up to 200”.
According to the Arms Control Association: “North Korea likely possesses additional fissile material that is not weaponized, but there is a high degree of uncertainty surrounding these estimates.
“North Korea has uranium enrichment technology and a known uranium enrichment facility at Yongbyon. It likely operates additional covert uranium enrichment facilities at other locations.
North Korea has developed nuclear capable missiles of various ranges, including ICBMs (intercontinental ballistic missiles), and claims to have developed tactical nuclear warheads.”
While the worldwide stockpile of nuclear weapons is gradually decreasing, the rate of those reductions has slowed considerably compared to the past three decades.
French President Emmanuel Macron recently declared that his country would be expanding its nuclear arsenal, stating: “The next 50 years will be an era of nuclear weapons.” Macron also revealed the launch of France’s new nuclear-armed submarine in 2036, named The Invincible.
The total number of warheads held in global military stockpiles is rising, with China, North Korea, India, Pakistan, France, the United Kingdom, and quite possibly Russia, all thought to be steadily bolstering their existing arsenals.
The USA has rapidly depleted its nuclear weapons stockpile in its current war with Iran, including Tomahawk missiles, and it remains to be seen whether it adds more to its existing inventory.
