Naval War College Review


In 1914 the brilliant and remarkably versatile English engineer, Frederick William Lanchester, published a series of articles which he later consolidated into a book entitled, Aircraft in Warfare: The Dawn of the Fourth Arm. The best-remembered result of his intellectual excursion into military theory is a simple mathematical expression of the principle of concentration, called the "n-square Law," that defines what Lanchester called the relative "fighting strengths" of military forces in terms of their "numerical strengths" and the "fighting values," of the individual units.
