Description
The Talismans were designed by Armstrong Whitworth for the Ottoman Navy, but were sub-contracted to Hawthorn Leslie and Company for building. They displaced 1,098 long tons (1,116 t). The ships had an overall length of 309 feet (94.2 m), a beam of 28 feet 7 inches (8.7 m) and a draught of 9 feet 6 inches (2.9 m). They were powered by three Parsons direct-drive steam turbines, each driving one propeller shaft, using steam provided by three Yarrow boilers. The turbines developed a total of 25,000 shaft horsepower (19,000 kW) and gave a maximum speed of 32 knots (59 km/h; 37 mph). The ships carried a maximum of 237 long tons (241 t) of fuel oil. The ships' complement was 102 officers and ratings. The hull form was considered particularly successful and was adopted for the V and W class of 1917, arguably the peak of destroyer development at the time.
The Talisman-class ships were heavily armed for their time, shipping five single QF 4-inch (102 mm) Mark IV guns. Two of the guns were side-by-side on the forecastle. The other guns were carried on the centreline; one between the first and second funnels, one after the searchlight platform and one on a bandstand on the quarterdeck. All the guns had half-shields. The ships were designed to accommodate three above water twin mounts for 21-inch (533 mm) torpedoes, but only two mounts were fitted in British service.
Ships
Originally to have been renamed Napier, Narborough, Offa and Ogre respectively, they were re-allocated "T" names in February 1915.
