Description
Ivanhoe displaced 1,370 long tons (1,390 t) at standard load and 1,888 long tons (1,918 t) at deep load. The ship had an overall length of 323 feet (98.5 m), a beam of 33 feet (10.1 m) and a draught of 12 feet 5 inches (3.8 m). She was powered by Parsons geared steam turbines, driving two shafts, which developed a total of 34,000 shaft horsepower (25,000 kW) and gave a maximum speed of 36 knots (67 km/h; 41 mph). Steam for the turbines was provided by three Admiralty 3-drum water-tube boilers. Ivanhoe carried a maximum of 470 long tons (480 t) of fuel oil that gave her a range of 5,530 nautical miles (10,240 km; 6,360 mi) at 15 knots (28 km/h; 17 mph). The ship's complement was 145 officers and enlisted men in peacetime.
The ship mounted four 45-calibre 4.7-inch Mk IX guns in single mounts, designated 'A', 'B', 'X', and 'Y' from front to rear. For anti-aircraft (AA) defence, Ivanhoe had two quadruple Mark I mounts for the 0.5 inch Vickers Mk III machine gun. She was fitted with two above-water quintuple torpedo tube mounts for 21-inch (533 mm) torpedoes. One depth charge rail and two throwers were fitted; 30 depth charges were originally carried, but this increased to 35 shortly after the war began. She was one of the four I-class destroyers fitted with minelaying equipment in late 1938 – January 1939 at Malta. This consisted of mounts for rails on the deck on which to carry the mines and an electric winch to move the mines down the rails. A pair of sponsons were added to the stern to allow the mines to clear the propellers when dropped into the sea. 'A' and 'Y' guns and both sets of torpedo tubes were modified to allow them to be removed to compensate for the weight of the mines. The ship could carry a maximum of 72 mines. Ivanhoe was fitted with the ASDIC sound detection system to locate submarines underwater.

Famous quotes containing the word description:
“Do not require a description of the countries towards which you sail. The description does not describe them to you, and to- morrow you arrive there, and know them by inhabiting them.”
—Ralph Waldo Emerson (1803–1882)
“A sound mind in a sound body, is a short, but full description of a happy state in this World: he that has these two, has little more to wish for; and he that wants either of them, will be little the better for anything else.”
—John Locke (1632–1704)
“The great object in life is Sensation—to feel that we exist, even though in pain; it is this “craving void” which drives us to gaming, to battle, to travel, to intemperate but keenly felt pursuits of every description whose principal attraction is the agitation inseparable from their accomplishment.”
—George Gordon Noel Byron (1788–1824)
