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.

A ship class is a group of ships of a similar design. This is distinct from a ship type, which might reflect a similarity of tonnage or intended use. For example, USSĀ Carl Vinson is a nuclear aircraft carrier of the Nimitz class.
