How many atomic bombs exist in the world today?
As a weapon of mass destruction, nuclear warheads are part of the defense arsenal of some countries in the world. There were approximately 12,705 nuclear warheads worldwide as of January 2022 and almost 90 percent of them belong to two countries: the United States and Russia.
Who owns the world's nukes? Despite progress in reducing nuclear weapon arsenals since the Cold War, the world's combined inventory of nuclear warheads remains at a very high level: nine countries possessed roughly 12,700 warheads as of early-2022.
As of 2019, there are 15,000 nuclear weapons on planet Earth. It would take just three nuclear warheads to destroy one of the 4,500 cities on Earth, meaning 13,500 bombs in total, which would leave 1,500 left.
At present, Russia maintains the highest number of nuclear weapons, with an estimated 6,257 total warheads.
Depending on its impact radius, even a Tsar bomb cannot destroy a whole country. Only a small country such as Vatican City or Monaco with land areas of 44 ha and 202 ha respectively can be completely destroyed using a nuclear weapon.
Nine countries possess nuclear weapons: the United States, Russia, France, China, the United Kingdom, Pakistan, India, Israel, and North Korea. In total, the global nuclear stockpile is close to 13,000 weapons.
Statista puts Russia's arsenal at 5,997 nuclear warheads as of January 2022 and the U.S. with 5,428 nuclear warheads. According to the Bulletin of the Atomic Scientists, Russia has a stockpile of around 4,477 weapons in its nuclear arsenal. In comparison, the U.S. has around 3,708 warheads.
Unless you stop the missile IMMEDIATELY upon launch, it is virtually impossible to stop an ICBM due to its speed. An anti missile system can, in theory, down an ICBM just after launch. But, that anti missile system would have to be within range of the launched ICBM to be effective.
Thus 1 bomb with a yield of 1 megaton would destroy 80 square miles. While 8 bombs, each with a yield of 125 kilotons, would destroy 160 square miles. This relationship is one reason for the development of delivery systems that could carry multiple warheads (MIRVs).
Can humans survive an atomic bomb?
Nuclear weapons are deadly, and after an impact on a major city tens to hundreds of thousands would likely die. But the worst destruction, where the chances of survival are least likely, is confined to a "severe damage zone," Buddemeier said.
Russia possesses a total of 5,977 nuclear warheads as of 2022, the largest stockpile of nuclear warheads in the world; the second-largest stockpile is the United States' 5,428 warheads. Russia's deployed missiles (those actually ready to be launched) number about 1,588, second to the United States' 1,644.
But a hydrogen bomb has the potential to be 1,000 times more powerful than an atomic bomb, according to several nuclear experts. The U.S. witnessed the magnitude of a hydrogen bomb when it tested one within the country in 1954, the New York Times reported.
Russia's Tsar bomba: World's most powerful nuclear weapon of mass destruction. The Tsar bomba exploded about 4 km above the ground and reportedly produced a mushroom cloud 60 km high.
According to the Nuclear Weapon Archive, 650 B83s are in “active service.” However, the destructive capability of the B83 pales in comparison with the most powerful bomb ever made: the Soviet Union's “Tsar Bomba,” which had a yield of 50 megatons—around 2,500 times more powerful than the weapon that destroyed Nagasaki.
Little of the land area covered by the five southern Nuclear-Weapon-Free Zones extends north of the Tropic of Cancer: only northern Mexico, northern Bahamas, northern Myanmar, and North Africa. However, the Central Asian and Mongolian zones are entirely in the North Temperate Zone.
A new study sponsored by the American Physical Society concludes that U.S. systems for intercepting intercontinental ballistic missiles cannot be relied on to counter even a limited nuclear strike and are unlikely to achieve reliability within the next 15 years.
Standard ones can have yields of 500 kilotons, 800 kilotons and even 1 megaton — equivalent to 1 million tons of TNT. Russia holds the record for the most powerful weapon ever exploded: In 1961, it tested a bomb of at least 50 megatons, nicknamed “Tsar Bomba” — or the ruler of all bombs.

The Tsar Bomba is the most powerful thermonuclear weapon ever detonated, as no other bomb as strong has ever been tested.
How big is a nuclear bomb?
Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing as little as 600 pounds (270 kg) can release energy equal to more than 1.2 megatonnes of TNT (5.0 PJ).
Tsar Bomba was tested at half its yield, 50 Mt. Still the largest detonation ever (3,333.33 Hiroshima sized bombs).. The seismic shock (and keep in mind it was an atmospheric detonation) was around a 5.25 earthquake and was still measurable on its third pass over the entire planet.
- Turn away and close and cover your eyes to prevent damage to your sight.
- Drop to the ground face down and place your hands under your body.
- Remain flat until the heat and two shock waves have passed.
A study last month found that the countries with the best hope of at least seeing their civilisation survive during the ten years after a nuclear war would be Argentina and Australia.
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.
Since the bombing of Hiroshima and Nagasaki, Japan has been a staunch upholder of antinuclear sentiments. Its postwar Constitution forbids the establishment of offensive military forces, and in 1967 it adopted the Three Non-Nuclear Principles, ruling out the production, possession, or introduction of nuclear weapons.
The first atomic bomb was built in Los Alamos, New Mexico, during World War II under a top secret U.S. government program called the Manhattan Project.
Make sure you have an Emergency Supply Kit for places you frequent and might have to stay for 24 hours. It should include bottled water, packaged foods, emergency medicines, a hand-crank or battery- powered radio to get information in case power is out, a flashlight, and extra batteries for essential items.
It would take a land- based missile about 30 minutes to fly between Russia and the United States; a submarine-based missile could strike in as little as 10 to 15 minutes after launch.
The number of casualties depends on the size of the weapon, where it's detonated, and how many people are upwind of the blast. Survivors of a nuclear attack would have about 15 minutes before sandlike radioactive particles, known as nuclear fallout, reached the ground.
What will happen if nuclear war starts?
According to a peer-reviewed study published in the journal Nature Food in August 2022, a full-scale nuclear war between the U.S. and Russia would kill 360 million people directly and more than 5 billion people would die from starvation.
Some estimates name Maine, Oregon, Northern California, and Western Texas as some of the safest locales in the case of nuclear war, due to their lack of large urban centers and nuclear power plants.
Recovery would probably take about 3-10 years, but the Academy's study notes that long term global changes cannot be completely ruled out. The reduced ozone concentrations would have a number of consequences outside the areas in which the detonations occurred.
A lot of people would die, of course: It's an A-bomb. But there are some easy steps that can feasibly save your life from the most fearsome weapon ever created. Oh, and spoiler alert, the answer isn't: crawl inside a fridge.
They found average global temperatures could drop between 15º and 25º Celsius, enough to plunge the planet into what they called “nuclear winter”—a deadly period of darkness, famine, toxic gases and subzero cold.
Nuclear fallout, or just simply fallout, known also as Black Rain, is the residual radioactive material that is propelled into the upper atmosphere after a nuclear black or a nuclear reaction that is conducted in an unshielded facility.
It's “Tsar Bomba”, and it is the most powerful device ever tested. H-Bombs could be made much bigger, but they are militarily useless. Tsar Bomba was tested at 50 megatons. If the tamper/pusher was made of U238, it would have yielded 100 megatons, the additional yield provided by fast fission.
Answer and Explanation: As far as we know, nobody currently has a Tsar Bomba. The Soviets only built the one that was detonated in 1961.
Tsar Bomba was the largest nuclear bomb ever, yielding an explosion equivalent to 57 megatons of TNT, ten times more powerful than all of the combined munitions used during World War II.
Tsar Bomba, (Russian: “King of Bombs”) , byname of RDS-220, also called Big Ivan, Soviet thermonuclear bomb that was detonated in a test over Novaya Zemlya island in the Arctic Ocean on October 30, 1961.
Who has Tsar Bomba?
On the morning of October 30, 1961, the Soviet Union carried out the Tsar Bomba test, a hydrogen bomb that was the most powerful nuclear weapon ever created and tested. The Tsar Bomba packed a punch of over 50 megatons, which is the equivalent of 50 million tons of conventional explosives.
The W54 (also known as the Mark 54 or B54) was a tactical nuclear warhead developed by the United States in the late 1950s. The weapon is notable for being the smallest nuclear weapon in both weight and yield to have entered US service.
Russia and the United States possess roughly 90% of the world's nuclear weapons, with over 5,500 weapons each. Learn more. Was this helpful?
With a maximum yield of 1.2 megatonnes of TNT (5.0 PJ), it has been the most powerful nuclear weapon in the United States nuclear arsenal since October 25, 2011 after retirement of the B53. It was designed by Lawrence Livermore National Laboratory.
| Type of Test | United States | Total |
|---|---|---|
| Atmospheric | 215 | 528 |
| Underground | 815 | 1,528 |
| Total | 1,0301 (Note: does not include atomic bombings of Hiroshima and Nagasaki.) | 2,056 |
Statista puts Russia's arsenal at 5,997 nuclear warheads as of January 2022 and the U.S. with 5,428 nuclear warheads. According to the Bulletin of the Atomic Scientists, Russia has a stockpile of around 4,477 weapons in its nuclear arsenal. In comparison, the U.S. has around 3,708 warheads.
In many cases, the weapons were dropped by mistake or jettisoned during an emergency, then later recovered. But three US bombs have gone missing altogether – they're still out there to this day, lurking in swamps, fields and oceans across the planet.
Today, the United States deploys 1,357 and Russia deploys 1,456 strategic warheads on several hundred bombers and missiles, and are modernizing their nuclear delivery systems.
The Tsar Bomba packed a punch of over 50 megatons, which is the equivalent of 50 million tons of conventional explosives. That's 10 times more powerful than all the munitions expended during World War Two and over 1,500 times the force of the atomic bombs dropped on Hiroshima and Nagasaki combined.
The United States detonated two atomic bombs over the Japanese cities of Hiroshima and Nagasaki on 6 and 9 August 1945, respectively. The two bombings killed between 129,000 and 226,000 people, most of whom were civilians, and remain the only use of nuclear weapons in armed conflict.
Are there 6 missing nukes?
Since 1950, there have been 32 nuclear weapon accidents, known as "Broken Arrows." A Broken Arrow is defined as an unexpected event involving nuclear weapons that result in the accidental launching, firing, detonating, theft or loss of the weapon. To date, six nuclear weapons have been lost and never recovered.
See 1965 Philippine Sea A-4 incident. A U.S. Navy A-4E Skyhawk aircraft with one B43 nuclear bomb on board fell off the aircraft carrier USS Ticonderoga into 16,200 feet (4,900 m) of water while the ship was underway from Vietnam to Yokosuka, Japan. The plane, pilot and weapon were never recovered.
With a maximum yield of 1.2 megatonnes of TNT (5.0 PJ), it has been the most powerful nuclear weapon in the United States nuclear arsenal since October 25, 2011 after retirement of the B53. It was designed by Lawrence Livermore National Laboratory.
Tsar Bomba, also called Big Ivan, needed a specially designed plane because it was too heavy to carry on conventional aircraft. The bomb was attached to a giant parachute to give the plane time to fly away.
