Alarm-class torpedo gunboat

The Alarm-class torpedo gunboat was the penultimate class of torpedo gunboat built for the Royal Navy. The class was contemporary with the early torpedo boat destroyers, which were faster and thus better suited to pursue enemy torpedo boats. By the First World War, ships of the class had either been sold, converted to submarine depot ships or minesweepers, or reduced to harbour service. Three of the 11 completed torpedo gunboats of the Alarm class were lost during the war while serving in the minesweeping role.
