The V and W class was an amalgam of six similar classes of destroyer built for the Royal Navy under the 9th, 10th, 13th and 14th of fourteen War Emergency Programmes during the First World War and generally treated as one class. For their time they were among the most powerful and advanced ships of their type in the world, and set the trend for future British designs.
At the outbreak of the Second World War Nazi Germany's Kriegsmarine had 21 destroyers in service, while another one was just being completed. These 22 vessels – comprising 3 classes – had all been built in the 1930s, making them modern vessels. Including that final pre-war vessel, a further 19 were brought into service during the war and more were captured from opposing navies, including the Italian Navy after the Italian Armistice with the Allies in 1943.
The Admiralty type leader, sometimes known as the Scott class, were a class of eight destroyer leaders designed and built for the Royal Navy towards the end of World War I. They were named after Scottish historical leaders. The function of a leader was to carry the flag staff of a destroyer flotilla, therefore they were enlarged to carry additional crew, offices and signalling equipment, allowing a fifth gun to be carried. These ships were contemporary with the Thornycroft type leader, distinguishable by their two narrow funnels of equal height, the Thornycroft designs latter having characteristic broad, slab-sided funnels.
