The C class as designated in 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 of the class was a top speed of 30 knots, a "turtleback" forecastle and that they all had three funnels. The funnels were spaced equidistantly and were of equal height, but the central one was thicker.
In 1913 all "30 knotter" vessels with 3 funnels were classified by the Admiralty as the "C" class to provide some system to the naming of HM destroyers (at the same time, the 4-funnelled, "30 knotters" became the "B" class and the 2-funnelled ships the "D" class). All vessels had the distinctive turtleback that was intended to clear water from the bows but actually tended to dig the bow in to anything of a sea, resulting in a very wet conning position and poor seaboats that were unable to reach top speed in anything but perfect conditions.
