Animated Chart: Nuclear Warheads by Country (1945-2022)
Visualizing The Nuclear Warheads of Countries Since 1945
Despite significant progress in reducing nuclear weapon arsenals since the Cold War, the world’s combined inventory of warheads remains at an uncomfortably high level.
Towards the late 1980s, the world reached its peak of stockpiled warheads, numbering over 64,000. In modern times, nine countries—the U.S., Russia, France, China, the UK, Pakistan, India, Israel, and North Korea—are estimated to possess roughly 12,700 nuclear warheads.
The animated chart above by creator James Eagle shows the military stockpile of nuclear warheads that each country has possessed since 1945.
Nuclear Warheads Currently in Possession by Countries
The signing of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) brought about a rapid disarmament of nuclear warheads. Though not immediately successful in stopping nuclear proliferation, it eventually led to countries retiring most of their nuclear arsenals.
As of 2022, about 12,700 nuclear warheads are still estimated to be in use, of which more than 9,400 are in military stockpiles for use by missiles, aircraft, ships and submarines.
Here’s a look at the nine nations that currently have nuclear warheads in their arsenal:
|Country||Military Stockpile||Retired Weapons||Total Inventory|
|🇺🇸 United States||3,708||1,720||5,428|
|🇬🇧 United Kingdom||180||45||225|
|🇰🇵 North Korea||20||0||20|
The U.S. and Russia are by far the two countries with the most nuclear warheads in military stockpiles, with each having close to 4,000 in possession.
Timeline: Key Events in the Nuclear Arms Race
At the dawn of the nuclear age, the U.S. hoped to maintain a monopoly on nuclear weapons, but the secret technology and methodology for building the atomic bomb soon spread. Only 10 countries have since possessed or deployed any nuclear weapons.
Here are a few key dates in the timeline of the nuclear arms race from 1945 to 2022:
August 6 & 9, 1945:
The U.S. drops two atomic bombs on Hiroshima and Nagasaki, Japan, decimating the cities and forcing the country’s surrender, ending the Second World War.
August 29, 1949:
The Soviet Union tests its first nuclear bomb, code-named First Lightning in Semipalatinsk, Kazakhstan. It becomes the second country to develop and successfully test a nuclear device.
October 3, 1952:
The UK conducts its first nuclear test at Montebello Islands off the coast of Western Australia, and later additional tests at Maralinga and Emu Fields in South Australia.
February 13, 1960:
France explodes its first atomic bomb in the Sahara Desert, with a yield of 60–70 kilotons. It moves further nuclear tests to the South Pacific, which continue up until 1996.
October 16–29, 1962:
A tense stand-off known as the Cuban Missile Crisis begins when the U.S. discovers Soviet missiles in Cuba. The U.S. intiaties a naval blockade of the island, with the crisis bringing the two superpowers to the brink of nuclear war.
October 16, 1964:
China becomes the fifth country to test an atomic bomb in 1964, code-named Project 596. The country would conduct an additional 45 atomic bomb tests at the Lop Nor testing site in Sinkiang Province through 1996.
July 1, 1968:
The NPT opens for signatures. Under the treaty, non-nuclear-weapon states agree to never acquire nuclear weapons, and nuclear powers must make a legal undertaking to disarm.
May 18, 1974:
India conducts an underground nuclear test at Pokhran in the Rajasthan desert, code-named the Smiling Buddha. Since conducting its first nuclear test, India has refused to sign the NPT or any subsequent treaties.
September 30, 1986:
Through the information provided by Israeli whistleblower and nuclear technician Mordechai Vanunu, The Sunday Times publishes a story that leads experts to conclude that Israel may have up to 200 nuclear weapons.
October 9, 2006:
After previously signing onto the NPT, North Korea breaks from the treaty and begins testing nuclear weapons in 2006. It has since gathered 20 nuclear warheads, though the actual number and their efficacy are unknown.
Though the threat of nuclear weapons never left, the latest growing tensions in Ukraine have brought the topic back into focus. Even as work towards disarmament continues, many of the top nuclear states hesitate to fully reduce their arsenals to zero.

Map Explainer: Sudan
This comprehensive map explainer covers both key facts about Sudan, as well as information on the violent power struggle unfolding there
Map Explainer: Sudan
The African nation of Sudan has been in the headlines, as intense fighting has rocked the country. As this bloody power struggle plays out, the map infographic above aims to provides key information on the conflict, as well as general facts and context about the country.
To begin, what exactly is happening in Sudan?
The 2023 Conflict in Sudan: A Primer
As explosions echo throughout Khartoum—Africa’s sixth largest urban area—many around the world are left wondering how the conflict escalated to this point. Here are five things to know:
- Two generals have been sharing power since a coup in 2021. The first is General Abdel Fattah al-Burhan, who leads the Sudanese Army. The second is General Mohamed Hamdan Dagalo (aka Hemedti), who leads the Rapid Support Forces (RSF) paramilitary group. This power-sharing arrangement was meant to be temporary, with an eventual transition to a civilian-led democracy. Instead, the situation devolved into conflict.
- Fighting broke out around the country in mid-April, with Khartoum becoming a major flash point. Flames billowed over the Khartoum airport, and the city’s military headquarters was reduced to a burned-out husk.
- As violence began to grip Sudan’s largest city, there was an exodus of foreign officials and citizens. In one particularly dramatic scene at the U.S. Embassy, nearly 100 people were escorted onto an aircraft by Navy SEALs and flown to nearby Djibouti.
- There have been a number of ceasefire agreements so far, but they’ve done little to stem the intense fighting.
- The stream of refugees fleeing the violence continues to grow. There is growing concern that this conflict will cause further instability in the region, as most of Sudan’s neighbors have their own histories with recent conflict, and many areas are facing food insecurity.
Unfortunately, Sudan is no stranger to conflict, having been ruled by the military for much of its existence. As of the writing of this article, there is technically a ceasefire in place, but fighting rages on. It remains to be seen how far these warring generals are willing to push the situation to assert their power.
Fast Facts About the Country of Sudan
Beyond headlines of conflict, Sudan is not a well-known country to many in the West. In the map above, we’ve also included more general information about geography, climate, population centers, and more.
Geography and Climate
Sudan is the third largest nation in Africa (16th globally), so there is a lot of climate and geographic variance within the country’s borders.
The country is located in Northeast Africa, directly below Egypt. Roughly speaking, its climate changes along a north–south axis, moving from arid to tropical. About two-thirds of the nation is arid and semi-arid, which is typical of countries with territory that includes the Sahara Desert.
The further south one goes in Sudan, the greener the surroundings get. The map below (which also includes the relatively new country of South Sudan) shows the extreme difference in vegetation from the north to south in the region.
The Nile River is a prominent feature running across this arid region, providing two-thirds of the country’s fresh water. In the south, the Blue and White portions of the Nile enter the country from South Sudan and Ethiopia, respectively. The rivers meet midway through the country and the Nile River flows northward, eventually reaching Egypt.
This flow of water from country-to-country can sometimes be a point of contention between Sudan, South Sudan, Ethiopia, and Egypt, who all rely on the river for power, fresh water, and irrigation.
Over 43 million people live in Sudan, which ranks it ninth in terms of population in Africa. Below, we can see that much of the Sudanese population is clustered in a couple of key areas, while much of the country remains sparsely populated.
Khartoum, the capital and largest city, is located in the interior of the country at the strategic point where the Blue and White Niles converge. This fast-growing city is shaped by the three sections surrounding the river junction—with Khartoum, North Khartoum, and Omdurman making up a metro area of 6.3 million people.
Sudan is divided into 18 states, five of which form the Darfur region in the west. If the name Darfur is familiar, it’s for good reason. In the 2000s, the region experienced a conflict marked by widespread violence, human rights abuses, and displacement, resulting in a humanitarian crisis. One of the generals involved in the current crisis, Hemedti, previously commanded the Janjaweed militias, which carried out some of the most egregious atrocities of the Darfur conflict.
In the northwest, Sudan borders the strategic Red Sea route. Port Sudan serves as the main entry point for imports and the primary export outlet for Sudanese commodities, including agricultural products (such as cotton, gum arabic, and sesame), minerals (such as gold), and livestock. The city has also been tapped to host a Russian naval base in the near future, though the recent power struggle in Sudan has potentially complicated negotiations.
As violence continues to rage in residential areas and people flee for safer areas, it remains to be seen how this conflict will influence population patterns within the country. How many people will be displaced? And once the smoke clears, will they return?
