Submarine Warfare, Past, Present, and Future

by Herbert C. Fyfe

LAUNCH OF U.S. SUBMARINE “SHARK.”

Rear-Admiral C. C. P. FitzGerald, in an article in the Empire Review for February, 1901, on “Our Naval Strength,” referring to submarines said:—“It seems a little risky to hold our hand altogether. We are said to be ‘watching,’ and no doubt it will be very convenient if we can allow others to spend their time and money on experiments and then just cut in at the right moment when the submarine boat has established itself as a practicable engine of warfare and build as many as we want with the unrivalled resources which we are so fond of talking about. But it should be remembered that secrets are better kept abroad than they are in England and that a new mechanical industry always takes some time to develop and to train the special workmen essential to its prosecution.”

Mr. Arnold Forster has himself said that an ounce of practice is worth a ton of theory, and it would be well if all officials thought as he does. There is far too little experimental work and practical trial of novel ideas both in the Army and the Navy. If we were never going to use our soldiers or our ships in actual warfare it would be both economical and prudent to wait until other nations had perfected inventions before adopting them ourselves. In this case we should never make any progress at all, for the reason that no improvement is final, and that the fleet of to-day is a totally different thing from the fleet of fifty years ago.

Si vis pacem para bellum. The essence of maritime war is, it has been well said, its suddenness, and a day gained in striking the first blow may make the difference between the fall of an empire and the annihilation of the enemy. To wait to consider to what use we can put submarine vessels and to postpone the question of discovering the most effective method of destroying the boats of the enemy until war breaks out is a suicidal policy, which, however, seemed for many years to appeal to a “Government of Amateurs.”

Had there been more experimental work before the outbreak of the Boer War our army would have probably finished its task sooner and with less loss of life. Questions such as the employment of heavy field ordnance, of telescopic sights, of shields for guns and rifles, of motors, of electricity, &c., will have to be considered when the war is over, but they should have received attention before hostilities commenced. If every nation would agree to maintain the status quo and to make no effort to keep its navy and its army abreast of the advances of modern scientific progress and invention, then the policy of our Admiralty and War Office would be excellently suited to our needs. As it is, however, Germany, France, the United States, Russia, and Japan are much more ready to improve their services than is Great Britain, whose officials, for the sake of peace and quiet, snub the inventor and smother their consciences by repeating that all is well in our army and navy. Only when great pressure is brought to bear on them will they stir themselves. Admiral Sir E. Fremantle recently suggested that there ought to be a committee on inventions always sitting, and Mr. Laird Clowes has appealed for readier official interest in certain recent inventions.

The experiments with the British submarines must be carefully watched in order that we may arrive at a well-reasoned opinion concerning their future. It may be that it will be decided that for our purposes a means of destroying the submarines of the enemy will be of more value than the boats themselves. On the other hand, the conclusion may be reached that for certain purposes this type of craft will be a useful adjunct to our fleet. Whatever the decision may be it is quite certain that the submarine boat will continue to receive improvements at the hands of inventors, and that as practical applications have been found for the Röntgen Rays and wireless telegraphy, so uses will be found for the submarine of the future which may be as great an improvement on the submarine of to-day as the Deutschland is over the Savannah, the first steam-packet that ever crossed the Atlantic.

Those who discuss submarine navigation as if it were quite a new development are apt to forget that the earliest use of the torpedo was in an under-water vessel. Bushnell and Fulton, no less than the Confederates of a later day, saw that their best chance of success lay in attacking by stealth, and though the modern Whitehead is a very different weapon to the cases of explosive used by Bushnell and Fulton, or the spar-torpedo employed by the Confederates in their Davids, there are still the same advantages to be gained by a submarine attack.

Whilst the torpedoists of the extreme school claim that torpedo vessels can attack with a very good chance of success in daylight, the more general opinion is that they will he utilised chiefly under cover of darkness, and that the destroyer and the smaller torpedo-boat would stand no chance in broad daylight against the tremendous artillery fire to which they would be subjected by the battleships singled out for attack. Even at night, however, the flare from her funnels might betray the destroyer.

A writer in the United Service Gazette a few years ago remarked that the development of quick-firing guns brought about by the increase in the offensive and defensive power of swift torpedo-boats threatened ere long to completely abolish the use of surface torpedo-boats in marine warfare unless the latter could be rendered proof against those terribly destructive weapons, the new rapid-firing guns of large calibre. To secure this invulnerability by the aid of armour would destroy the speed and hardiness of the torpedo-boats, and it had long been the opinion amongst naval officers, more especially on the Continent and in America, that if the torpedo is to be used for successful attack it would have to be discharged from a vessel which was rendered invulnerable by being totally submerged—that is to say, from a submarine torpedo-boat.

The submarine boat of the future will be a diving torpedo-boat capable of manœuvring (1) on the surface, (2) awash with conning tower only above the water, and (3) beneath the waves.
