“Sea power in the broad sense, includes not only the military strength afloat that rules the sea or any part of it by force of arms, but also the peaceful commerce and shipping from which alone a military fleet naturally and healthfully springs, and on which it securely rests.’’
Captain Alfred Thayer Mahan, U. S. Navy
Seapower once involved, fundamentally, only the surface of the seas. In the past few decades, however, aircraft operating over the seas and submarines operating just below the surface of the seas have increased the dimensions for the applications of seapower. Today, not only are we experiencing the revolutionary effects of radical changes in the sea transportation industry, but we are apparently also on the threshold of an even more profound change in the nature of seapower.
