HMS Swift was a unique destroyer leader designed and built for the Royal Navy prior to World War I, another product of Admiral "Jackie" Fisher's relentless quest for speed. The class was envisioned as a large ocean-going destroyer, capable of both the usual destroyer requirements and of high-speed scouting duties for a major fleet.
Design
Fisher put his specification to the Director of Naval Construction in October 1904. The DNC replied that it was not strong enough. In 1905 a revised design for from on a 1,400 t hull was pushed through followed by one for 36 knots on 1,350 tons from. Given only four weeks to produce their tender, the major shipyards - Cammell Laird, Thornycrofts, Fairfields, John Brown and Armstrong Whitworth - put forward designs. There were problems meeting the requirements and the high cost of the designs. A final design was not agreed until mid-December 1905; Cammell Laird only taking the order on their proviso that amendments would be needed. The vessel was, 1,680 tons, armed with four Mark VIII 4-inch guns and two torpedo tubes, and oil-fired Parsons steam turbines with four shafts. The vessel was priced at £236,000 and given the building name Flying Scud. Work started in December 1906 and she was launched on 7 December 1907. In the initial contract the Admiralty included an offer of £18,000 for every knot more than 36 knots. In trials over a measured mile at Skelmorlie in March 1909 she suffered a number of mechanical failures and never managed better than 35.099 knots, at a shocking fuel consumption of 27.5 tons/hour out of a total stock of only 180 tons. Later trials, up to September 1909, used 26 different propeller designs in an attempt to reach the required speed. The Admiralty finally accepted her as she was for £236,764 with £44,240 in penalties for the failure to reach contracted speed and late delivery. After arguments from the builder as to the difficulty of the task the penalties were reduced to £5,000. Reports to the press at the time claimed Swift could reach 38 knots. Despite being the prototype for her class, no other leaders were built before the outbreak of war in 1914. Her weak armament, and high cost caused Arthur Wilson to note "I do not think we require any repetition of Swift in the immediate future." Naval historianAnthony Preston has for this reason given a sharp criticism of the ship, describing it as a 'very expensive and disappointing outcome'.
Service history
At the beginning of the war as leader of the 4th Torpedo Boat Destroyer Flotilla she joined the Grand Fleet. In October, Swift was dispatched from Scapa Flow to search for the protected cruiser when she did not return from patrol. Instead, Swift found one of Hawkes rafts carrying one officer, and 21 men. Hawke was torpedoed and sunk by a German U-boat, with only a handful of survivors. The extreme weather of the northern winter seas was more than Swift could withstand and in 1915, after a short refit, she was reassigned to the Dover Patrol. In 1916 her two forward 4-inch guns were replaced with a single 6-inch gun. Her forward decks were reinforced to cope with the mass and recoil of the new gun and she also received additional bridge structures and two anti-aircraft guns. On the night of 20–21 April 1917, while commanded by Ambrose Peck and accompanying the destroyer, she engaged a force of six enemy destroyers in the Battle of Dover Strait. In a confused fight she hit G85 with a torpedo while Broke rammed, and became enmeshed with, G42. The remaining German ships fled, Swift pursued but took several hits and was compelled to slow. She returned to assist Broke and rescue survivors of G42 before returning to Plymouth. Due to the poor performance of the 6-inch gun her armament was returned to two 4-inch guns. In the spring of 1918 she was with the Offshore Squadron during the First Ostend Raid. Quietly sidelined and scrapped after the war, her size was not approached in the Royal Navy until the Tribal class of 1936.
