The Drake class were enlarged and improved versions of the Cressy class designed by Sir William White, Chief Constructor of the Royal Navy, to counter the new French armoured cruiser Jeanne d'Arc.[1] The ships had an overall length of 553 feet 6 inches (168.7 m), a beam of 71 feet 4 inches (21.7 m) and a deep draught of 26 feet 9 inches (8.2 m). They displaced 14,150 long tons (14,380 t) and proved to be good seaboats in service.[2] Their crew consisted of 900 officers and other ranks.[3]
The ships were powered by two 4-cylinder triple-expansion steam engines, each driving one shaft, using steam provided by 43 Belleville boilers. The engines produced a total of 30,000 indicated horsepower (22,000 kW) and the Drakes easily reached their designed speed of 23 knots (43 km/h; 26 mph).[2] They carried a maximum of 2,500 long tons (2,500 t) of coal.[3]
The ship's waterlinearmour belt had a maximum thickness of 6 inches (152 mm) and was closed off by 5-inch (127 mm) transverse bulkheads. The armour of the gun turrets and their barbettes was 6 inches thick while the casemate armour was 5 inches thick. The protective deck armour ranged in thickness from 1–2.5 inches (25–64 mm) and the conning tower was protected by 12 inches (305 mm) of armour.[2]
Ships
The following table gives the build details and purchase cost of the members of the Drake class. Standard British practice at that time was for these costs to exclude armament and stores. The compilers of The Naval Annual revised costs quoted for British ships between the 1905 and 1906 editions. The reasons for the differences are unclear.
The ships served in the First World War with only two surviving it. Good Hope was sunk at the Battle of Coronel in 1914 and Drake was torpedoed in 1917. Drake was also used to ferry Russian bullion (gold) in October 1914 from Arkhangelsk. The gold (equivalent of $39 million) was security for western loans. The transfer took place at high seas, 30 miles off the coast in the dead of night.[10]
