The third HMS Halcyon was a Dryad-class torpedo gunboat of the Royal Navy. Once described as "perhaps the smallest and least formidable vessel that ever crept into the 'Navy List,' ", she was launched in 1894 and was put up for sale before World War I. She was recommissioned in 1913, was converted to a minesweeper and served under the orders of the Admiral Commanding Coast Guard and Reserves. She was sold for breaking in 1919.
Ordered under the Naval Defence Act of 1889, which established the "Two-Power Standard", the class was contemporary with the first torpedo boat destroyers. With a length overall of 262 ft 6 in (80.01 m), a beam of 30 ft 6 in (9.30 m) and a displacement of 1,070 tons, these torpedo gunboats were not small ships by the standard of the time; they were larger than the majority of World War I destroyers. Halcyon was engined by Hawthorn Leslie and Company with two sets of vertical triple-expansion steam engines, two locomotive-type boilers, and twin screws. Halcyon produced 6,000 indicated horsepower (4,500 kW), nearly twice the power of the rest of her class. She was capable of 19 or 20 knots (37 km/h). She carried between 100 and 160 tons of coal and was manned by 120 sailors and officers.
The armament when built comprised two QF 4.7-inch (12 cm) guns, four 6-pdr guns and a single 5-barrelled Nordenfelt machine gun. Her primary weapon was five 18-inch (450-mm) torpedo tubes,[Note 1] with two reloads. On conversion to a minesweeper in 1914 two of the five torpedoes were removed.
World War I service
In August 1914 she became the ship of the Senior Naval Officer North Sea Fisheries, serving under the orders of the Admiral Commanding Coast Guard and Reserves. Located at Yarmouth, she was involved in the Raid on Yarmouth.
On 29 July 1917, Halcyon spotted a periscope near the Smiths Knoll buoy east of Yarmouth, and carried out a ramming attack, followed by dropping two depth charges. Halcyon was credited with sinking the submarine, UB-27.
She was sold to J H Lee of Dover for breaking on 6 November 1919.
