How many tons of TNT is a nuke?

Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon

thermonuclear weapon

The practical maximum yield-to-weight ratio for fusion weapons (thermonuclear weapons) has been estimated to six megatons of TNT per metric ton of bomb mass (25 TJ/kg). Yields of 5.2 megatons/ton and higher have been reported for large weapons constructed for single-warhead use in the early 1960s.

Nuclear weapon yield - Wikipedia

weighing as little as 600 pounds (270 kg) can release energy equal to more than 1.2 megatonnes of TNT (5.0 PJ).

How many tons of TNT is the atomic bomb equivalent to?

The most striking difference between the explosion of an atomic bomb and that of an ordinary T.N.T. bomb is of course in magnitude; as the President announced after the Hiroshima attack, the explosive energy of each of the atomic bombs was equivalent to about 20,000 tons of T.N.T.

How much TNT is in a modern nuke?

Their combined power yielded an equivalent of about 36,000 tons of TNT. But modern nukes are something else. Only sixteen years later, the Soviets designed a bomb 3,000 times more powerful at 100,000,000 tons of TNT. Fearing devastation beyond control, they toned it down a bit and tested the bomb at 50,000,000 of TNT.

How much TNT is in the biggest nuke?

The highest-yielding test series conducted by the US. USSR, most powerful nuclear weapon ever detonated, yield of 50 megatons, (50 million tons of TNT). In its "final" form (i.e. with a depleted uranium tamper instead of one made of lead) it would have been 100 megatons.

How many tonnes of TNT was Hiroshima?

The bomb was dropped on Hiroshima, Japan, August 6, 1945, at 8:15 AM. A B-29 dropped the bomb from 31,000 feet. The bomb exploded about 1,500 feet above the city with a force of 15,000 tons of TNT.

A 500 Ton Pile of TNT About to Explode and Fake a Nuclear Explosion

What would a 1000 megaton bomb do?

The letter then, more chillingly, exposed the capabilities of a bomb 10 times more deadly. It continues: “The corresponding radius of effect for a 1000 megaton bomb would be 100 miles, that is to say, an area of about 30,000 square miles would be affected and in clear weather would have an even more devastating effect.

How many tons of TNT is a supernova?

A type 1a supernova explosion gives off 1–2×10⁴⁴ joules of energy, which is about 2.4–4.8 hundred billion yottatons (24–48 octillion (2.4–4.8×10²⁸) megatons) of TNT, equivalent to the explosive force of a quantity of TNT over a trillion (10¹²) times the mass of the planet Earth.

How big is a 1 megaton explosion?

Thus, a 1 kiloton nuclear weapon is one which produces the same amount of energy in an explosion as does 1 kiloton (1,000 tons) of TNT. Similarly, a 1 megaton weapon would have the energy equivalent of 1 million tons of TNT. One megaton is equivalent to 4.18 x 10¹⁵ joules.

How big of a blast is a nuke?

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).

How big would a nuke blast be?

Within a 6-km (3.7-mile) radius of a 1-megaton bomb, blast waves would produce 180 metric tons of force on the walls of all two-story buildings, and wind speeds of 255 km/h (158 mph). In a 1-km (0.6-mile) radius, the peak pressure is four times that amount, and wind speeds can reach 756 km/h (470 mph).

How big is a 20 megaton bomb?

The first atomic bomb

According to the NukeMap, a weapon with a 20-kiloton yield produces a fireball with a radius of 260 meters, making its total width the size of 5 football fields. It would spew deadly radiation over an area 7 miles in width, and would produce third-degree burns in an area over 12 miles in width.

How heavy is a nuclear warhead?

Dimensions. The W80 is physically quite small: the physics package itself is about the size of a conventional Mk. 81 250-pound (110 kg) bomb, 11.8 inches (30 cm) in diameter and 31.4 inches (80 cm) long, and only slightly heavier at about 290 pounds (130 kg).

How big is the average nuke?

Drozdenko said US nukes generally had explosive yields equivalent to about 300 kilotons of TNT, while Russian nukes tended to range from 50 to 100 kilotons to 500 to 800 kilotons, though each country has more powerful nuclear weapons.

How big is a 4 megaton nuclear bomb?

What if a bomb with a yield of 4 megatons - a convenient term for a blast equivalent of 4 millions of TNT, or about 200 times larger than the Hiroshima bomb - had detonated at Goldsboro? We can take a guess courtesy of NUKEMAP 3D, a nuclear blast simulation created by science historian Alex Wellerstein.

What was the TNT equivalent of the Hiroshima bomb?

On this basis of comparison, the Hiroshima bomb was of about 15 kilotons – that is, of 15 thousand tonnes of TNT equivalent – and that at Nagasaki was of 25 kilotons (ca.

How many nukes would it take to destroy the US?

The absolute doomsday scenario is a “nuclear winter.” For that to happen, the US and Russia would have to use about 2,000 nukes each and destroy major cities and targets, Toon told me.

Can you shoot down a nuke?

The Aegis ballistic missile defense-equipped SM-3 Block II-A missile demonstrated it can shoot down an ICBM target on 16 Nov 2020.

What is the biggest nuke in the world?

Tsar Bomba

On Oct. 30, 1961, the Soviet Union dropped the most powerful nuclear weapon ever exploded on the archipelago of Novaya Zemlya, north of the arctic circle.

How big is the fireball of a nuke?

Within seven-tenths of one millisecond from the detonation, the fireball from a 1-megaton weapon is about 440 feet across, and this increases to a maximum value of about 5,700 feet in 10 seconds. It is then rising at a rate of 250 to 350 feet per second.

How hot is a nuclear fireball?

A primary form of energy from a nuclear explosion is thermal radiation. Initially, most of this energy goes into heating the bomb materials and the air in the vicinity of the blast. Temperatures of a nuclear explosion reach those in the interior of the sun, about 100,000,000° Celsius, and produce a brilliant fireball.

How many megatons are US nukes?

Nuclear weapons vary in their destructive power. In the United States' current nuclear arsenal, the most powerful bomb is the B83, which has a maximum yield of 1.2 megatons, making it 60 times more powerful than the bomb dropped on Nagasaki, Japan, in 1945.

Is a supernova stronger than a nuke?

Supernovae are one of the most energetic explosions in nature, equivalent to the power in a 1028 megaton bomb (i.e., a few octillion nuclear warheads).

How many tons of TNT is a gamma ray burst?

The blast would bathe Earth in the equivalent of 300,000 megatons of TNT, 30 times the world's nuclear weaponry, with the gamma-ray and X-ray radiation stripping Earth of its ozone layer.
