The Admiralty W class comprised 21 vessels, all ordered in December 1916, although the two ships ordered from Yarrow were cancelled in April 1917 and replaced by the orders for two Yarrow S class (Tomahawk and Torch). The Admiralty W class ships were a follow on from the Admiralty V class, with minimal changes, primarily in that the triple torpedo tube mounting was now ready and all these vessels shipped two of these mountings from new. They also had a taller mainmast.

Famous quotes containing the word class:

    “I am both a public and a private school boy myself, having always changed schools just as the class in English in the new school was taking up Silas Marner, with the result that it was the only book in the English language that I knew until I was eighteen—but, boy, did I know Silas Marner!”
    —Robert Benchley (1889–1945)
