The Tsar Bomba is the most powerful thermonuclear weapon ever detonated, as no other bomb as strong has ever been tested.
The explosive power of a thermonuclear bomb can be hundreds or thousands of times more powerful than atomic bombs. While the force of the bombs dropped on Hiroshima and Nagasaki were measured in kilotons (one thousand tons) of TNT, the force of thermonuclear bombs is measured in megatons (a million tons).
Australia does not possess weapons of mass destruction, although it has participated in extensive research into nuclear, biological and chemical weapons in the past.
To increase the probability of an intercept, the United States has to shoot multiple interceptors at each incoming ballistic missile. At present, because its inventory of interceptors is limited, the United States can shoot down only a handful of ballistic missiles that have relatively unsophisticated countermeasures.
But a hydrogen bomb has the potential to be 1,000 times more powerful than an atomic bomb, according to several nuclear experts.
The other form of radiation is neutron activation. Neutrons can cause non-radioactive materials to become radioactive when caught by atomic nuclei. However, since the bombs were detonated so far above the ground, there was very little contamination—especially in contrast to nuclear test sites such as those in Nevada.
The mushroom cloud was 25 miles wide at its base and almost 60 miles wide at its top. At 40 miles high, it penetrated the stratosphere. Everything within three dozen miles of the impact was vaporized, but severe damage extended to 150 miles radius—enough to entirely annihilate any modern major city, including suburbs.
The Tsar Bomba is the single most physically powerful device ever deployed on Earth, the most powerful nuclear bomb tested and the largest human-made explosion in history.
Tsar Bomba (in Russian, Царь-бомба) is the Western nickname for the Soviet RDS-220 (РДС-220) hydrogen bomb (code name Vanya). Detonated by the Soviet Union on October 30, 1961, Tsar Bomba is the largest nuclear device ever detonated and the most powerful man-made explosion in history.
In addition, it was estimated that heat from the blast would have caused third-degree burns up to 62 miles (100 km) distant. Although a success, Tsar Bomba was never considered for operational use.
Tsar Bomba is the most powerful nuclear bomb ever made. One bomb would be stanched, but a million could easily destroy the Earth.
“Emperor” remained the official title for subsequent Russian rulers, but they continued to be known as “tsars” in popular usage until the imperial regime was overthrown by the Russian Revolution of 1917. The last Russian tsar, Nicholas II, was executed by the Soviet government in 1918.
A declassified document shared by nuclear historian Alex Wellerstein gives the verdict that scientists at the Los Alamos laboratory and test site reached in 1945. They found that "it would require only in the neighborhood of 10 to 100 Supers of this type" to put the human race in peril.
Chernobyl reactor 4 is no longer burning. The reactor was originally covered after the disaster, but it resulted in a leak of nuclear waste and needed to be replaced.
"Compared with other nuclear events: The Chernobyl explosion put 400 times more radioactive material into the Earth's atmosphere than the atomic bomb dropped on Hiroshima; atomic weapons tests conducted in the 1950s and 1960s all together are estimated to have put some 100 to 1,000 times more radioactive material into ...
More than 30 years on, scientists estimate the zone around the former plant will not be habitable for up to 20,000 years. The disaster took place near the city of Chernobyl in the former USSR, which invested heavily in nuclear power after World War II.
Although the United States has never constructed a doomsday machine, the concept was mimicked in the doctrine of mutually assured destruction (MAD), which was the basis of both U.S. and Soviet nuclear strategy in the 1960s and '70s.
Neutron bombs, or more precisely, enhanced [neutron] radiation weapons were also to find use as strategic anti-ballistic missile weapons, and in this role, they are believed to remain in active service within Russia's Gazelle missile.
A hydrogen bomb has never been used in battle by any country, but experts say it has the power to wipe out entire cities and kill significantly more people than the already powerful atomic bomb, which the U.S. dropped in Japan during World War II, killing tens of thousands of people.
Pentagon Estimates China Has Doubled Number of Missiles That Can Hit U.S. A new U.S. military report has assessed that its Chinese counterpart has doubled the number of far-reaching missiles capable of hitting the United States over the course of the past year.
The U.S. Air Force has a top-secret space weapon and is preparing to show it to the world. For months, the service has been preparing to declassify the "black" weapon, but wants to get the timing right, according to a Breaking Defense exclusive.
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.
