Destroyers were built by various yards and outwardly significantly differed from each other (in particular, Laurel, Liberty, Lark, Landrail, Laverock and Linnet had 3 boilers instead of 4 and two funnells. Ardent had two funnells and 4 boilers).
The step-by-step improvements in previous designs showed to good advantage in the destroyers of the 1912-13 Programme. Although originally given Shakespearian and Waverley Novel names they were all given 'L' names by Admiralty order of 30 September 1913, thus becoming the first alphabetical class under the new organisation. After some discussion about the possibilily of finding a design cheaper than the Acorns, in January 1912 the Controller issued a fresh Staff Requirement for a twin-screw TBD with 24,500shp, 3 102mm semiautomatic guns, iwo twin torpedo-tubes and three boilers. Following the success of the semi-geared turbines in Badger and Beaver (Garland had not been laid down) two, Leonidas and Lucifer, were to have 'all-geared' turbines. Frahm anti-rolling tanks were also approved. As designed the'Ls' had short level funnels like the Acherons but height was raised to 6m during construction. The White and Yarrow boats were two-funnelled but the rest had three funnels. As built all were fitted to stow and lay 4 Vickers Elia Mk.IV mines, but there is no record of them laying these mines, and when the Elia Mk.IV was replaced by the 'H' type in 1917 ihere was no reason to retain the capability. Two additional boats were ordered from Beardmore late in 1914. They were intended to be extra 'M' class vessels but to save time the builders were ordered to repeat the design of the two 'L's already in hand, and they were renamed in February 1915.
1917, all but Lawford and Legion: can not carry mines.
1917, Lawford, Legion: were converted to carry new "H" type mines.
1917-1918, most survived: + 1 x 1 - 40/39 2pdr QF Mk II
