hting value. They, however, differ 72 British Submarines slightly from each other: D.i has a submerged displacement of 595 tons;D.2 of 600 tons; and the remaining vessels of this class of 620 tons. They have an approximate length of 150 feet and a beam of 15 feet. Heavy-oil engines of 1,200 h.-p. drive them at a maximum speed of 16 knots an hour on the surface, and electric motors of 550 h.p. give them a submerged speed of just over 10 knots an hour. All these vessels have twin-screws situated below the centre line. Their cruising range on the surface is 4,000 miles, and when submerged 120 knots at 7 knots an hour. These vessels were the first to be fitted with a special and more efficient pattern of electric storage battery and a safer type of electric motor. The armament of the Ds consists of two bow and one stern tube with six 18-inch White-head torpedoes. Ds 4, 5, 6, 7, and 8 are also fitted with a small quick-firing,high-angle gun for defence against air-craft. This gun is fixed on a disappearing

The heavy-oil engines of nearly 2,000 h.-p. give them a surface speed of over 16 knots, while the electric engines of 800 h.-p. drive them at a maximum speed of 10 knots an hour when submerged. Their surface cruising range is 5,000 miles at economical speed, and the submerged endurance 140 knots at 8 knots an hour.In point of armament the Es are far 74 British Submarines more powerful than their predecessors,being fitted with four tubes and carrying six of the largest and most powerful W
