The S-class destroyers were improved versions of the preceding Modified R class. They displaced 1,075 long tons (1,092 t).[2] The ships had an overall length of 276 feet (84.1 m), a beam of 26 feet 8 inches (8.1 m) and a draught of 9 feet (2.7 m). They were powered by two Brown-Curtis geared steam turbines, each driving one propeller shaft, using steam provided by two Yarrow boilers. The turbines developed a total of 27,000 shaft horsepower (20,000 kW) and gave a maximum speed of 36 knots (67 km/h; 41 mph). The ships carried a maximum of 301 long tons (306 t) of fuel oil that gave them a range of 2,750 nautical miles (5,090 km; 3,160 mi) at 15 knots (28 km/h; 17 mph). The ships' complement was 90 officers and ratings.[3]

Seafire was armed with three QF 4-inch (102 mm) Mark IV guns in single mounts and a single 2-pounder (40 mm) "pom-pom" anti-aircraft gun. The ship was fitted with two twin mounts for 21-inch (533 mm) torpedoes.[2] Two additional single mounts were positioned abreast the bridge at the break of the forecastle for 18-inch (45 cm) torpedoes. All torpedo tubes were above water and traversed to fire.[4]

Construction and career

Seafire was ordered as part of the second batch of the S class and was built by John Brown & Company, Clydebank and launched on 10 August 1918.[1] She saw service during the Allied intervention in the Russian Civil War. She was one of the obsolete destroyers handed over to the shipbreakers Ward in part-payment for RMS Majestic on 14 September 1936, and was then broken up at Inverkeithing.[1]
