Design and Description
Two armoured cruisers of a new design, HMS Duke of Edinburgh and Black Prince, the latter named for Edward, the Black Prince, were ordered for the Royal Navy as part of the 1902–03 Naval Estimates. They were the first ships to be designed for the Royal Navy under the supervision of the new Director of Naval Construction, Sir Philip Watts. The new design was significantly larger than the previous Monmouth and Devonshire class cruisers, mounting a heavier main armament of six 9.2 in (234 mm) guns in single turrets.
Duke of Edinburgh displaced 12,590 long tons (12,790 t) as built and 13,965 long tons (14,189 t) fully loaded. The ship had an overall length of 505 feet 6 inches (154.1 m), a beam of 73 feet 6 inches (22.4 m) and a draught of 27 feet (8.2 m). She was powered by four-cylinder triple-expansion steam engines, driving two shafts, which produced a total of 23,000 indicated horsepower (17,000 kW) and gave a maximum speed of 23 knots (43 km/h; 26 mph). The engines were powered by 20 Babcock & Wilcox water-tube boilers and six cylindrical boilers. The ship carried a maximum of 2,150 long tons (2,180 t) of coal and an additional 600 long tons (610 t) of fuel oil that was sprayed on the coal to increase its burn rate. At full capacity, she could steam for 8,130 nautical miles (15,060 km; 9,360 mi) at a speed of 10 knots (19 km/h; 12 mph). The ship's complement was 789 officers and enlisted men.
Her main armament consisted of six BL 9.2-inch Mk X guns in single turrets, two on the centreline and two on each beam, giving a broadside of four 9.2 in guns. Her secondary armament of four BL 6-inch Mark XI guns was arranged in single casemates. They were mounted amidships on the main deck and were only usable in calm weather. Twenty Vickers QF 3-pounders were fitted, six on turret roofs and fourteen in the superstructure. The ship also mounted three submerged 18-inch torpedo tubes.

“I always consider the settlement of America with reverence and wonder, as the opening of a grand scene and design in providence, for the illumination of the ignorant and the emancipation of the slavish part of mankind all over the earth.”

“Once a child has demonstrated his capacity for independent functioning in any area, his lapses into dependent behavior, even though temporary, make the mother feel that she is being taken advantage of....What only yesterday was a description of the child’s stage in life has become an indictment, a judgment.”
