Alfred Thayer Mahan - Impact On Naval Thought

Impact On Naval Thought

Timeliness contributed no small part to the widespread acceptance and resultant influence of Mahan's views. Although his history was relatively thin (he relied on secondary sources), the vigorous style and clear theory won widespread acceptance of navalists across the world. Sea power supported the new colonialism which was asserting itself in Africa and Asia. Given the very rapid technological changes underway in propulsion (from coal to oil, from boilers to turbines), ordnance (with better fire directors, and new high explosives) and armor and emergence of new craft such as destroyers and submarines, Mahan's emphasis on the capital ship and the command of the sea came at an opportune moment.

Mahan's name became a household word in the German navy, as Kaiser William II ordered his officers to read Mahan, and Admiral Alfred von Tirpitz (1849–1930) used Mahan's reputation to finance a powerful surface fleet.

Between 1890 and 1915, Mahan and British admiral John Fisher (1841–1920) faced the problem of how to dominate home waters and distant seas with naval forces not strong enough to do both. Mahan argued for a universal principle of concentration of powerful ships in home waters and minimized strength in distant seas, while Fisher reversed Mahan by utilizing technological change to propose submarines for defense of home waters and mobile battle cruisers for protection of distant imperial interests.

The French were less susceptible to Mahan's theories. French naval doctrine in 1914 was dominated by Mahan's theory of sea power and therefore geared toward winning decisive battles and gaining mastery of the seas. But the course of World War I changed ideas about the place of the navy, as the refusal of the German fleet to engage in a decisive battle, the Dardanelles expedition of 1915, the development of submarine warfare, and the organization of convoys all showed the navy's new role in combined operations with the army. The navy's part in securing victory was not fully understood by French public opinion in 1918, but a synthesis of old and new ideas arose from the lessons of the war, especially by admiral Raoul Castex (1878–1968), from 1927 to 1935, who synthesized in his five-volume Théories Stratégiques the classical and materialist schools of naval theory. He reversed Mahan's theory that command of the sea precedes maritime communications and foresaw the enlarged roles of aircraft and submarines in naval warfare. Castex enlarged strategic theory to include nonmilitary factors (policy, geography, coalitions, public opinion, and constraints) and internal factors (economy of force, offense and defense, communications, operational plans, morale, and command) to conceive a general strategy to attain final victory.

Ideologically, the United States Navy initially opposed replacing its sailing ships with steam-powered ships after the Civil War; Mahan argued that only a fleet of armored battleships might be decisive in a modern war. According to the decisive-battle doctrine, a fleet must not be divided; Mahan's work encouraged technological improvement in convincing opponents that naval knowledge and strategy remained necessary, but that domination of the seas dictated the necessity of the speed and predictability of the steam engine.

His books were greatly acclaimed, and closely studied in Britain and Imperial Germany, influencing the build up of their forces prior to the First World War. Mahan influenced the naval portion of the Spanish-American War, and the battles of Tsushima, Jutland, and the Atlantic. His work influenced the doctrines of every major navy in the interwar period.

Mahan's concept of sea power extended beyond naval superiority; that in peace time, states should increase production and shipping capacities, acquire overseas possessions — either colonies or privileged access to foreign markets— yet stressed that the number of coal fuel stations and strategic bases should be few, not to drain too many resources from the mother country.

Although Mahan's influence on foreign powers has been generally recognized, only rather recently have scholars called attention to his role as significant in the growth of American overseas possessions, the rise of the new American navy, and the adoption of the strategic principles upon which it operated. He died in Washington a few months after the outbreak of World War I.
