text: Proposed conversion In the early 1950s, it was proposed to convert the five remaining ships of the M class, together with seven War Emergency Programme destroyers to Type 62 Air Direction Frigates. The conversion would have involved replacement of the ships' armament and sensors. The initial proposal would have armed the ships with a twin 4-inch gun mount, a twin 40 mm Bofors gun and a Squid anti-submarine mortar. Type 982 and 983 air direction radars would be fitted, as would Type 162 and 166 sonars. In March 1952, the programme was reduced, as the War Emergency Destroyers were too small to accommodate the heavy radars. Later that year, it was decided to substitute a US twin 3"/50 caliber gun mount for the 4-inch guns. The project was finally abandoned in May 1954, partly owing to the condition of the ships and poor shock-resistance.
  Ships
  L class
  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  armament. Six of the eight were war losses, with the surviving pair being broken up in 1948.
  M class
  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.
