Armor and the gun are natural and now hereditary foes. The function of the one is to resist, that of the other ever to attack. Since the beginning of the modern era in navies, there has been ceaseless strife for mastery between these two elements of warship design, the gun ever becoming more powerful, and the armor—at first through growing thickness and later through improved material—opposing a steadily more stubborn front. The official report of an English committee made in the year 1860 states that,—

“Vessels clothed in rolled-iron plates of four and a half inches’ thickness are to all practicable purposes invulnerable against any projectile that can be brought to bear against them at any range.”

The advance which forty years have seen may be shown by the single statement that the Krupp 15.7-inch gun develops sufficient energy to penetrate at the muzzle 47 inches of wrought iron. The battleship is at best but a series of compromises, each factor of the structure yielding or growing as the skill or whim of her designer may indicate. In the present stage of this unceasing change, the gun would appear to be the victor, and the power of this mighty 132-ton rifle seems scarcely needed on the sea. The distinguished chief of ordnance of the United States navy, in his annual report for 1898, says:—

“The development of the 12-inch gun has been so great and its power so much increased that the Bureau is of opinion that hereafter it will be the maximum calibre that it will be advisable to install on future battleships.”

With armor, as with the torpedo, the talent of Europe reaped where the genius of America had sown. John Stevens of New Jersey was the first inventor of modern times to suggest the application of armor to a floating battery, his plans being submitted to the United States government during the war of 1812. They received, however, no serious consideration, and to France, forty-two years later, fell the honor of attaining the first practical results in the building of ironclads. Members of the Stevens family, however, continued the experiments of its founder, until by the year 1841 they had determined the thickness of iron necessary to stop spherical projectiles at point blank range, and the comparative resisting powers of iron and oak. These results led to an appropriation by Congress, in 1854, of $500,000 to begin work upon an ironclad,—the Stevens battery,—which vessel, however, never left the ways and was eventually broken up.
