HMS Gorgon was the first commissioned vessel of the Cyclops-class breastwork monitors constructed for the Royal Navy in the 1870s. This class was a modified development of the earlier Cerberus class, designed for coastal defense and harbor protection. The ship measured 225 feet (68.6 meters) in length between perpendiculars, with a beam of 45 feet (13.7 meters) and a draught of 16 feet 3 inches (4.95 meters) at deep load. Displacing approximately 3,480 long tons (3,540 tonnes), HMS Gorgon had a crew of 156 officers and men. Power was provided by two 4-cylinder horizontal direct-acting steam engines, each driving a single propeller, producing a combined 1,670 indicated horsepower (1,250 kW). This propulsion enabled a maximum speed of 11 knots (20 km/h). The vessel carried 250 long tons (250 tonnes) of coal, granting her a range of 3,000 nautical miles (5,600 km) at a cruising speed of 10 knots (19 km/h). The armament comprised four 10-inch rifled muzzle-loading guns mounted in twin-gun turrets—two fore and two aft of the superstructure. These guns could fire both solid shot and explosive shells, with hydraulic jacks used for elevation and depression. The ship's armor scheme featured a complete waterline belt of wrought iron, 8 inches (203 mm) thick amidships, tapering to 6 inches (152 mm) at the ends. The superstructure and conning tower were fully armored with 8–9 inches (203–229 mm) of wrought iron. The gun turrets had faces of 10 inches (254 mm) and sides and rear of 9 inches (229 mm). All vertical armor was backed by 9–11 inches (229–279 mm) of teak, providing substantial protection. The decks were relatively thin, at 1.5 inches (38.1 mm). HMS Gorgon served until she was placed on the non-effective list of ships in January 1902, alongside her sister ships Cyclops and Hecate. She was sold for scrap in 1903, marking the end of her maritime service. Her construction and armor reflect the Royal Navy's focus on coastal defense and armored protection during the late 19th century, making her a notable example of Victorian naval innovation.
