Discussion in naval circles throughout the world turned then to the question of whether it were better to build heavier ships with heavier armament, or to build lighter and faster ships designed to "hit and get away." The British authorities inclined toward the former view, and between 1901 and 1904 the British navy was augmented with the Implacable, London, Bulwark, Formidable, Venerable, Queen, Irresistible, and Prince of Wales—each of the heretofore unheard-of displacement of 15,000 tons. In spite of their size they were comparatively fast, having an average speed of 18 knots; they did not need, and were not equipped with heavier armor, having plates as thin as 3 inches and as thick as 12. They were built to "take punishment," and therefore they had no greater armament than the vessels previously named. The naval program of 1908 and 1904 also included the Duncan, Albemarle, Russell, Cornwallis, and Exmouth, each 1,000 tons lighter than the ships of the Implacable type, but with the same equipment, defensive and offensive, and of the same speed. And in the same program, as if to offset the argument for heavier and stronger ships, there were included the lighter and faster ships, Swiftsure and Triumph, displacing only 11,500 tons, but making 19 knots. Their speed permitted and necessitated lighter armor—10 inches through at the thickest points—and their armament was also of a lighter type, for their four largest guns were capable of firing 10-inch shells.
Germany was becoming a naval rival worthy of notice, and the insular position of England came to be a matter of serious concern by 1906. Britain has never considered the building of land forts for her protection—her strength has always been concentrated in floating war machines. She now began to build veritable floating forts, ships of 16,350 tons displacement. By the end of 1906 she had ready to give battle eight ships of this class, the King Edward VII, Commonwealth, Dominion, Hindustan, Africa, Hibernia, Zealandia, and Britannia. Speed was not sacrificed to weight, for they were given a speed of 18.5 knots, developed by engines of 18,000 horsepower. Their thinnest armor measured 6 inches, and their heavy guns were protected with plates 12 inches thick. The 12-inch gun was still the heaviest piece of armament in the British navy, and these eight ships each carried four of that measurement, as well as four 9.2-inch guns, ten 6-inch guns, fourteen rapid-fire guns of 3 inches, two machine guns, and four torpedo tubes.
Now that it was seen that ships of enormous displacement could also be swift, England committed herself to the building of ships of even greater size. In 1907 came the first of the modern dreadnoughts, so-called from the name which was given to the original ship of 17,900 tons displacement. The Dreadnought made the marvelous speed (for a ship of that size) of 21 knots, which she was enabled to do with turbine engines of 23,000 horsepower. Her armor measured from 8 to 11 inches in thickness, and her great size enabled her to carry as high as ten 12-inch guns. Her minor batteries were strong in proportion.
Then, as if taking her breath after a stupendous effort, England in the following year built two ships of 16,000 tons displacement, the Lord Nelson and the Agamemnon, with speed, armor, and armament much lower than those of the Dreadnought. But having taken a rest, Britain was again to make a great effort, launching in 1909 the Temeraire, Superb, and Bellerophon, monsters displacing 18,600 tons. With engines of 23,000 horsepower that could drive them through the seas at 21 knots, ready to ward off blows with armor from 8 to 11 inches thick, firing at the same time volleys from ten 12-inch guns down to sixteen 4-inch rapid firers.
Naval architecture had now taken a definite turn, the principal feature of which was the tremendous size of the destructive floating machines. England, a leader in this sort of building, in 1910 built the Vanguard, Collingwood, and St. Vincent, each displacing 19,250 tons. Nor were they lacking in speed, for they made, on an average, 21 knots. The 20,000-ton battleship was then a matter of months only, and it came in the following year, when the Colossus, Hercules, and Neptune were launched. It was only in the matter of displacement that these three ships showed any difference from those of the Vanguard class; there were no great innovations either in armament or armor. But in the same year, 1911, there were launched the Thunderer, Monarch, Orion, and Conqueror, each of 22,500 tons, and equipped with armor from 8 to 12 inches thick, for the days of 3-inch armor on first-class warships had gone forever. These had a speed of 21 knots, and were the first British ships to have anything greater than a 12-inch gun. They carried as a primary battery ten 13.5-inch guns, and sixteen 4-inch guns, along with six more of small caliber as their secondary battery.
In 1912 and 1913 there was only one type of warship launched having 23,000 tons displacement with 31,000 horsepower, a half a knot faster than previous dreadnoughts, and carrying, like the previous class, ten 13.5-inch guns, along with some of smaller caliber. The ships of this class were the King George V, Ajax, Audacious, and Centurion.
The year 1914 saw even more terrible machines of death launched. Two types were put into the water, the first that of the Iron Duke class, of which the other members were the Benbow, Emperor of India, and Marlborough. They showed great improvement in every point; their speed was 22.5 knots, their displacement 25,000 tons, and their torpedo tubes five. Like their immediate predecessors, they carried a primary battery of ten 13.5-inch guns, along with the smaller ones, and their armor measured from 8 to 12 inches in thickness. The second type of the year was that of the Queen Elizabeth and Warspite class. They surpassed all the warships when they were built. Their speed for their size was the greatest—25 knots. They had the largest displacement among warships—27,500 tons; they had the thickest armor, ranging from 8 to 13.5 inches; they had the most improved form of engines—oil burners, developing 58,000 horsepower; and most marvelous of all was their primary battery, which consisted of eight 15-inch guns. The largest gun yet made had been the 16-inch gun, for use in permanent position in land forts, and, with the German army, for a mobile force. It now was shown that the modern warship could carry a gun as heavy as any on land. There were in the course of construction when the war broke out eight more such monsters, the Malaya, Valiant, and Barham, sister ships of the Queen Elizabeth, and the Royal Oak, Resolution, Royal Monarch, Ramillies, and Renown, each of 29,000 tons displacement, but having the same armament as the Queen Elizabeth. All of these were hastened to completion as soon as war was declared.
At the time of the declaration of war England had, in addition to these greatest ships, a number of supporting ships such as the ten battle cruisers, Indomitable, Invincible, Indefatigable, Inflexible, Australia, New Zealand, Queen Mary, Princess Royal, Lion, and the Tiger. Their displacements ranged from 17,250 to 28,000 tons, and their speeds from 25 to 30 knots, the last being that of the Tiger. Their speed is their greatest feature, for their armament and batteries are much lighter than those of the first-line ships.
Next, there were ready thirty-four high-speed cruisers of quite light armament and armor. There were six of the Cressy type, four of the Drake type, nine of the same type as the Kent, six of the same class as the Antrim, six like the Black Prince, three of the same class as the Shannon, together with seventeen heavily protected cruisers, of which the Edgar was the prototype. The rest of the British navy needs no detailed consideration. It consisted at the outbreak of the war of 70 protected light cruisers, 134 destroyers, and a number of merchant ships convertible into war vessels, together with submarines and other small ships.
The navy of France stood fourth in the list of those of the world powers at the time the war started. There were eighteen old vessels, built between 1894 and 1909, including the Carnot class (corresponding to the British ship Magnificent), the Charlemagne, Bouvet, Suffren, République, and Démocratie classes. The most modern of these types displaced no more than 14,000 tons, made no more than 18 knots, and carried primary batteries of 12-inch guns.
Some improvement was made in the six ships of the Danton class which were built in 1911 and 1912. They displaced 18,000 tons, had armor from 9 to 12 inches thick and carried guns of 12-inch caliber. They correspond
