HMS Gorgon was the first ship commissioned of the four Cyclops-class breastwork monitors built for the Royal Navy during the 1870s.

Design and description

The Cyclops-class ships were modified versions of the Cerberus class.[1] The ships had a length between perpendiculars of 225 feet (68.6 m), a beam of 45 feet (13.7 m), and a draught of 16 feet 3 inches (4.95 m) at deep load. They displaced 3,480 long tons (3,540 t). Their crew consisted of 156 officers and men.[2] Gorgon had two 4-cylinder horizontal direct-acting steam engine, each driving a single propeller shaft. The engines produced a total of 1,670 indicated horsepower (1,250 kW) during the ship's sea trials which gave her a maximum speed of 11 knots (20 km/h; 13 mph). They carried 250 long tons (250 t) of coal,[3] enough to steam 3,000 nautical miles (5,600 km; 3,500 mi) at 10 knots (19 km/h; 12 mph).[4]

The ships mounted four 10-inch rifled muzzle-loading guns in twin-gun turrets fore and aft of the superstructure. The guns could fire both solid shot and explosive shells.[5] They were mounted on carriages that used hydraulic jacks to elevate and depress the guns.[6]

The Cyclops class had a complete waterline belt of wrought iron that was 8 inches (203 mm) thick amidships and thinned to 6 inches (152 mm) at the ends. The superstructure and conning tower was fully armoured, the reason it was called a breastwork, with 8–9 inches (203–229 mm) of wrought iron. The gun turrets had 10 inches on their faces and 9 inches on the sides and rear. All of the vertical armour was backed by 9–11 inches (229–279 mm) of teak. The decks were 1.5 inches (38.1 mm) thick.[7]

Construction and career

Together with her sister ships, the Cyclops and the Hecate, she was placed on the non-effective list of ships in January 1902.[8] She was sold for scrap the following year.
