B class destroyer (1913)

From Wikipedia, the free encyclopedia

The B class of 1913 was a heterogeneous group of torpedo boat destroyers (TBDs) built for the Royal Navy in the late-1890s. They were constructed to the individual designs of their builders to meet Admiralty specifications, the uniting feature being a specified top speed of 30 knots and four funnels, although the funnel spacings differed between ships. All "30 knotter" with 4 funnels vessels being classified by the Admiralty as the B class in 1913 to provide some system to the naming of HM destroyers (all "30 knotter" vessels with 3 funnels were classified by the Admiralty as the C class and those with 2 funnels became the D class). All vessels had a distinctive "turtleback" forecastle that was intended to clear water from the bow, but actually tended to dig the bow in to anything of a sea, resulting in a very wet conning position.

They generally displaced around 350 tons, one third more than the preceding A class, giving an increase in speed of 3 knots over the 27 knotters. Length was around 210 feet. All were powered by triple expansion steam engines and had coal-fired water-tube boilers. Albacore, Arab, Bonetta and Express however were builder's specials had steam turbines fitted in addition to, or in lieu of, the reciprocating engines, giving 6,000 to 9,000 shp for 26.75 to 31 knots. Armament was one QF 12 pounder on a bandstand on the forecastle, five QF 6 pounder (two sided abreast the conning tower, two sided between the funnels and one on the quarterdeck) and 2 single tubes for 18 inch torpedoes.

The Palmers special types, built in 1908, were replacements for the River class Gala and the C class Tiger that had collided and sank that year. They were generally similar to the River (or E class) design, but were grouped with the B class as they possessed only 2 funnels and were similarly armed, and made 27 knots on turbines.
