Super fact 48 : Since 1945 we have set off more than 2,000 Nuclear Bombs corresponding to a yield of an estimated 42,000 times that of the Hiroshima Bomb.
According to the Arms Control Association there’s been 2,056 nuclear bomb tests. According to the UN there’s been more than 2,000 nuclear bomb tests, and according to Wikipedia there’s been 2,121 nuclear bomb tests, totaling 635 Megaton. Using the typical yield estimate for the Hiroshima bomb of 15 Kiloton that corresponds to more than 42,000 Hiroshima bombs. I think most of us know about the Hiroshima and Nagasaki bombs and we know about nuclear testing. However, I think the number of tests and the large total yield will come as a surprise to many, at least it was a surprise to me. That is why I consider this a super fact.
Nuclear Landscaping
It may also come as a surprise that many of these tests were not for military purposes. Another usage for nuclear bombs is nuclear landscaping. Towards the end of the 1950’s the existing Panama Canal was thought to be insufficiently large and some people, including Edward Teller, the father of the Hydrogen bomb (Thermonuclear bomb), suggested that a new wider and deeper canal could be built simply by using nuclear bombs to blow multiple huge holes across Panama. The US was also interested in creating a new harbor in Alaska using nuclear bombs.
Thus, Project Plowshare was created to achieve this. As part of the Project Plowshare 35 nuclear warheads were detonated. The Soviet Union also had a similar program named “Nuclear Explosions for the National Economy” that included 124 nuclear bomb tests. Due to concerns over radioactive fallout the nuclear landscaping projects were eventually put to rest. The last Plowshare detonation was on May 17, 1973. The book Atomic Awakening by James Mahaffey recounts the history of nuclear testing and nuclear landscaping in greater detail.
Project Orion
Another non-military use of nuclear bomb testing was Project Orion. Project Orion was a study conducted from 1956 to 1964 by the US Air Force, NASA, and DARPA into the viability of a nuclear pulse spaceship that would be directly propelled by a series of atomic explosions behind the craft. A thick steel pusher plate would catch the blast and accelerate the ship forward.
The “Pascal B” shot in Operation Plumb Bob in 1957 was the first nuclear weapons test of the pusher concept. The Limited Test Ban Treaty of 1963 made it difficult to continue with the project. According to the book Atomic Awakening, if the design had been successfully completed, we could have created an interstellar spaceship that could have taken a crew and a large load to other planets and stars.
I can add that According to Atomic Awakening, in addition to Nuclear Landscaping and Project Orion, Nuclear Blasts were a tourist attraction.
Number of Nuclear Tests by Country
Below is a list of countries and the number of nuclear tests that they’ve performed according to the Arms Control Association and Wikipedia.
- The United States – 1,030 – According to Wikipedia – 1,032
- The USSR/Russia – 715 – According to Wikipedia – 727
- France – 210 – According to Wikipedia – 215
- United Kingdom – 45 – According to Wikipedia – 88
- China – 45 – According to Wikipedia – 47
- North Korea – 6 – According to Wikipedia – 6
- India – 3 – According to Wikipedia – 3
- Pakistan – 2- According to Wikipedia – 2
However, it should be noted that partially due to nuclear arms control legislation such as; the Limited Test Ban Treaty (LTBT): Signed in 1963, the Threshold Test Ban Treaty (TTBT): Signed in 1974, and the Comprehensive Nuclear-Test-Ban Treaty (CTBT) opened for signing in 1996, the number of nuclear tests have been significantly reduced. This is illustrated by the graph below from Our World in Data. The last nuclear test was done by North Korea in 2017.
Tsar Bomba
The biggest nuclear bomb ever exploded was RDS-220, or AN602, or Tsar Bomba. It was detonated by the Soviet Union on October 30th, 1961, on the arctic island of Novaya Zemlya, and yielded more than 50 Megaton. In other words, it was 3,300 times more powerful than the Hiroshima bomb. According to Atomic Awakening, windows in Finland 1,900 kilometers (1,180 miles) away shattered. There are no cities large enough to match the size of the explosion. This is the kind of bomb that could obliterate states or small countries.
Tsar Bomba was a so-called thermonuclear device, or a hydrogen bomb as they are typically called. Hydrogen bombs are much more powerful than fission bombs, such as Uranium bombs or Plutonium bombs. To read my related post called “Ukraine Gave up Thousands of Nuclear Warheads” click here.
