The meaning ofsea power has been evasive since man began to exploit the sea. The list of definitions produced by scholars who have made an honourable attempt to explain it is extensive. The large number ofindividuals involved in this task has only managed to intensify the degree of intellectual turbulence. Many people have come to the conclusion that the challenge is far too great and, as a result, made a decision to sue for peace. This same misfortune has occurred to 1a..Ild. air, and space power. The quandary over a definition for all four power generators is solved by providing a structured and well-formulated model based on history's great strategic thinkers. The primary facilitator for this task is Rear Admiral Alfred Thayer Mahan and, therefore, his contribution makes him worthy of title recognition. The explanations developed in this thesis resulted from history, strategic theory,' related words and definitions, as well as elements of national power. Power based on strictly physical appearance is discredited as superficial.' This opens geographic boundaries traditionally associated with the four powers to allow formulation of unconventional factors not previously considered. Sea, land, air, and space power are not themselves physical. They instead signify a measure of applied pressure in varying forms. This may be directly or indirectly linked to their specific geographic domain. They exist within the confines of pressure application which, after all, is power being applied. Where that power originates from is not the important factor. The important factor is the recipient's location. This is the essence ofsea power.
