Model. The development of destroyers during World War I was marked by an increase in dimensions due to the necesity for remaining at sea over extended periods. The 'Tobago' was one of five destroyers known as the Thornycroft 'S' clas, built at Southampton between 1918 and 1919. These destroyers were 275.75 ft long with a displacement of 1087 tons. Their armament consisted of four 21-inch torpedo tubes in pairs on two turntables and two 18-inch torpedo tubes on racks under the bridge. In addition, there were three 4-inch guns and one 2-pounder pom-pom.
