War Emergency Programme destroyers

The War Emergency Programme destroyers were destroyers built for the British Royal Navy during World War I and World War II.

The 323 destroyers ordered during the First World War belonged to several different classes and were the subject of 14 separate War Programmes between 1914 and 1918. 40 of these were cancelled at the end of the war. The total excludes destroyers building in UK for other navies which were purchased for the Royal Navy following the outbreak of war.
