This is coolbert: The two thirds (2/3) root law is an interesting phenomenon relating to nuclear weapons. When the U.S. Air Force discovered this, they must have thought this was the proverbial "sliced bread". This law says that a bunch of very small nuclear weapons going off at once on the same target will have the same effect as just one much larger weapon going off on the same target. How does this work? Take a 1 megaton nuclear bomb. Take 1000 [kt's, 1 megaton] and get the two thirds (2/3) root of 1000. It is about 100. What this says is that ten 10 kiloton bombs going off on the same target all at once has the same effect as one 1 megaton bomb. With this law, you can then design a whole lot of small bombs and target them against the same target and get the same effect as one very large bomb. Advantages here. A very big aircraft or missile dedicated to carrying the one big bomb can be superseded by a whole lot of smaller delivery systems of varying types. Aircraft of a variety of types, cruise missiles, artillery shells, etc. These all can be used to deliver the smaller nuclear weaponry, giving you much greater versatility and flexibility in your operational concepts. [Try this to verify your calculations. Take 100 and find the one and one half [1.5) power of 100. It is close to 1000. This is the value in kilotons (1 megaton) from which the original two thirds root calculation was made. This is a verification]
