The L and M class was a class of sixteen destroyers which served in the British Royal Navy during World War II. The ships of the class were launched between 1939 and 1942.
The L class (also known as the Laforeys) were approved under the 1937 Naval Estimates. Four of these ships (Lance, Lively, Legion and Larne) were built with 4-inch (100 mm) armament instead of 4.7 inch. Six of the eight were war losses, with the surviving pair being broken up in 1948.
The M Class were built under the 1939 Naval Estimates. They served in the Home Fleet until 1944 and then went to the Mediterranean. Three were wartime losses; of the five survivors, the Musketeer was broken up in 1955 and the other four sold to Turkey in 1958.
