The Yarrow M class was a class of ten destroyers built for the Royal Navy that saw service during World War I. They were generally similar to the standard Admiralty M-class destroyer, but were instead designed by the builder, Yarrow & Company. Generally, they had two instead of three shafts, as well as two funnels and a straight stern, with the bridge set well back from the forecastle. The first trio were two knots faster than the Admiralty M type, despite less installed power and one less shaft; the installed power was increased for the later vessels. Jane's Fighting Ships describes the class as "very successful boats", and all ten vessels survived throughout the war to be broken up during the 1920s. Moon, Mounsey and Musketeer were each fitted to carry a kite balloon.
