To cope with this formidable rival, which, whether right or wrong in principle, must, under England’s policy, be surpassed, the ships of the Admiral class were designed. In these the main battery is mounted in two barbettes built high out of water, near the extremities of the vessel, while in a central broadside are carried the armor-piercing and rapid-fire guns. The engines, boilers, and barbette communications are protected by a water-line belt of thick armor which covers about forty-five per cent. of the ship’s length; at the upper edge of this there is a protective deck, and at its ends athwartships bulkheads are erected; before and abaft the belt and beneath the water-line there is a protective deck, together with the usual minute subdivision into water-tight compartments. The barbettes and the cylindrical ammunition tubes which extend from the belt-deck to the barbette floors are strongly armored. Owing to the strong protest made against these vessels, more efficient armor protection has been given to the battle-ships lately laid down.
From this very hasty and incomplete review it may be gathered that the first and most lasting influence in the development of battle-ships is due to France and England, though the Monitor had no little share in the result. It is difficult to say, in the ceaseless struggle for something which, if not good, is new, what may be the outcome of the latest efforts to revolutionize the question, or, curiously enough, to bring it back to the point whence its departure was taken. Whatever may be the courage of one’s opinion, there is not sufficient data—a first-class war can only supply these—upon which to say, Yea, yea! or Nay, nay! and prophecy is certain to be without honor, especially as the discussions given in the appendices demonstrate how the wisest and most experienced have no substantial agreement in views.
An editorial in a late number of the Broad Arrow declares that “the days of armored plate protection are, in the opinion of many thinking men, coming to a close. The gun is victorious all along the line, and the increased speed given to the torpedo-boat, taken in conjunction with the destructive efficiency attained by the torpedo, makes it a questionable policy to spend such large sums of money as heretofore upon individual ships.” There is no room here to give the various arguments, though very clever and ingenious they are, by which this position is fortified; it may be added, however, that to a large degree this is the opinion of Admiral Aube, the late French Minister of Marine, and undoubtedly this declaration re-echoes the shibboleth of those other French officers who, in the absolute formula of their chief, Gabriel Charmes, insist that “a squadron attacked at night by torpedo-boats is a squadron lost.”
English authorities, with a few notable exceptions, do not go so far as their more impulsive, or, from the Gallic stand-point, less conservative neighbors. Chief Constructor White believes that at no time in the war between gun and armor has the former, as the principal fighting factor, so many chances of success. He concedes the value of light, quick-firing guns in association with heavy armaments, grants the importance of rams, torpedoes, submarine boats, and torpedo-vessels generally, but denies that the days of heavily armored battle-ships are ended. Lord Charles Beresford asserts that the value of large guns at sea is overestimated, advocates from motives of morals and efficiency mixed armaments, agrees to the great, yet subordinate, importance of the usual auxiliaries, and insists that England builds cumbersome and expensive battle-ships only because of their possession by her dangerous rivals.
There are equally rigorous disagreements upon all the other types of armored, unarmored, and auxiliary vessels, as needs must be, so long as the naval policies of no two nations can be alike. England and Russia are at opposite poles, so far as their environments are concerned, and between France and Turkey the differences are as radical as their national instincts and ambitions. But, among all, England is as isolated as her geographical situation. Whatever fleets other nations may assemble, whatever types other countries may deem best for their interests, England, whose existence depends upon her naval strength, must have all; not only the best in quality, but so many of every class that she will be able to defend her integrity against any foe that assails it. England can take no chances.
Upon one point alone, the necessity of high speed, is there substantial agreement. Less than four years ago fifteen or sixteen knots were accepted as a maximum beyond which profitable design could not be urged. Greater speed, it is true, had been attained by our first type of commerce destroyer. In February, 1868, the Wampanoag ran at the rate of 16.6 knots for thirty-eight hours, and made a maximum of 17.75 knots; but great as was the achievement, there is a general acceptance of the fact that this vessel was a racing-machine, and not in the modern sense a man-of-war.
Fighting-ships, with the power to steam thousands of miles at sea without recoaling, are now being built under contracts which, for every deficiency in speed or horse-power, pay penalties that at our former summit of expectations would have been prohibitive to ship construction; and, what is more startling yet, the bonus which goes to any increase upon this speed proves the co-relation between scientific attainment and popular appreciation of the subject, and shows how readily the impossibilities of yesterday become the axioms of to-morrow.
The development of speed has therefore a special interest. Between 1859 and 1875, that tentative period which led to such wonderful realizations, the highest speed, under the most favorable circumstances, of large war-vessels was fourteen knots; in the smaller classes of unarmored ships it ranged between eight and thirteen, while that attained by fast cruisers was from fifteen to sixteen and a half knots. In 1886 Italian armored vessels made eighteen knots. Cruisers like the Japanese Naniwa-Kan and the Italian Angelo Emo reached nearly nineteen, and the Reina Regente, launched in February last, is expected to steam over twenty. Torpedo-vessels beginning in 1873 with fourteen knots are now running twenty-five, and at the same time the type has so much increased in size and importance as to be an essential and not an accessory in naval warfare.
It is impossible to explain the difficulties which have beset this development, because the conditions that surround any attempt at speed-increase are such as can be properly understood only by those who have technical training; and then, too, the great ocean racers have so much accustomed the public to wonderful sea performances that the results are accepted without a knowledge of the credit which is due the mechanical and marine engineers who have achieved them. But with greater experience the higher, surely, will be the appreciation which every one must give; for, in the words of Chief Constructor White, “when it is realized that a vessel weighing ten thousand tons can be propelled over a distance of nine knots in an hour by the combustion of less than one ton of coal—the ten-thousandth part of her own weight—it will be admitted that the result is marvellous,” and that “‘the way of a ship in the midst of the sea’ is beyond full comprehension.”
