The Cricket-class coastal destroyers were a class of small torpedo boat destroyers intended to complement the Royal Navy's Tribal-class destroyers. The first Cricket and Dragonfly were ordered in 1905 and launched in early 1906. In practice they were not strong enough for open ocean operations and were reclassified as 1st Class Torpedo boats. The first twelve had been given names but were then given the numbers TB1 to TB12; the following two batches of 12 ships were only ever given numbers. The last was launched in 1909. Those that survived the war were sold off from 1920 to 1921
