The Tribal or F class was a class of destroyer built for the Royal Navy. Twelve ships were built between 1905 and 1908 and all saw service during World War I, where they saw action in the North Sea and English Channel as part of the 6th Flotilla and Dover Patrols.

Design

The preceding River or E class destroyers of 1903 had made 25.5 knots (47.2 km/h; 29.3 mph) on the 7,000 ihp (5,200 kW) provided by triple expansion steam engines and coal-fired boilers, although HMS Eden was powered by steam turbines.[1] In November 1904, the First Sea Lord "Jackie" Fisher proposed that the next class of destroyers should make at least 33 knots (61 km/h) and should use oil-fired boilers and steam turbines as a means of achieving this.[2] This resulted in a larger ship to provide the required doubling of installed power over their predecessors, but also pushed the design to the limits of capability of contemporary technology. As a result, the Tribals were severely compromised and a somewhat retrograde step after the excellent River class; they were lightly built and proved to be fragile in service. More alarmingly however, they were only provided with 90 tons of bunkerage, and with high fuel consumption resulting from the unheard of power of 12,500 shp (9,300 kW), they were very uneconomical and had a severely limited radius of action; Afridi and Amazon once used 9.5 tons of oil each simply to raise steam for a three-mile (5 km) return journey to a fuel depot.

Design details were left to the individual builders, as was Royal Navy practice at the time for destroyers. As a result there was some heterogeneity of appearance, with the number of funnels varying from three to six in Viking; the latter, with two single and two pairs of funnels becoming the only six-funneled destroyer ever built. With a light mainmast aft, they were the first British destroyers to have two masts.

The first five ships were designed with the armament of three QF 12 pounder guns, an improvement from the single 12 pounder and five six-pounder guns that the River-class was completed with, while the number of torpedoes remained at two 18-inch (450-mm) tubes.[3][4] From the sixth ship, Saracen, onwards, however, the armament was again increased, to a pair of BL 4-inch (102 mm) guns, with one gun mounted forward and another on the quarterdeck.[5] From October 1908, the first five ships were modified by adding another pair of 12 pounder guns.[6]

Ships

Five vessels were ordered and built under the 1905-06 Programme.

Five more vessels were proposed, but only two were ordered and built under the 1906-07 Programme.

A final five vessels were ordered and built under the 1907-08 Programme.

Following the damage to Nubian and Zulu in October 1916, it was proposed on 8 November 1916 that the two undamaged 'ends' might be joined together, which was completed at Chatham Royal Dockyard 7 June 1917 by joining the undamaged fore section of Zulu and the rear section of Nubian respectively. The resulting destroyer was commissioned on 7 June 1917 as Zubian, which was sold for scrapping 1919.
