The I-class ships were improved versions of the preceding H-class. They displaced 1,370 long tons (1,390 t) at standard load and 1,888 long tons (1,918 t) at deep load. The ships had an overall length of 323 feet (98.5 m), a beam of 33 feet (10.1 m) and a draught of 12 feet 6 inches (3.8 m). They were powered by two Parsons geared steam turbines, each driving one propeller shaft, using steam provided by three Admiralty three-drum boilers. The turbines developed a total of 34,000 shaft horsepower (25,000 kW) and gave a maximum speed of 35.5 knots (65.7 km/h; 40.9 mph). Intrepid carried a maximum of 455 long tons (462 t) of fuel oil that gave her a range of 5,500 nautical miles (10,200 km; 6,300 mi) at 15 knots (28 km/h; 17 mph). The ships' complement was 145 officers and ratings.
The ships mounted four 4.7-inch (120 mm) Mark IX guns in single mounts. For anti-aircraft (AA) defence, they had two quadruple Mark I mounts for the 0.5 inch Vickers Mark III machine gun. The I class was fitted with two above-water quintuple torpedo tube mounts for 21-inch (533 mm) torpedoes. One depth charge rack and two throwers were fitted; 16 depth charges were originally carried, but this increased to 35 shortly after the war began.
Construction and career
In the Second World War, Intrepid attacked and sank the German submarine U-45 south-west of Ireland on 14 October 1939 in company with the destroyers Ivanhoe and Inglefield. She participated in the pursuit and destruction of the German battleship Bismarck in May 1941, and in Operation Pedestal, the escorting of a convoy to Malta in August 1942.
