Project history: 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.
Modernizations: 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
Naval service: Laforey was sunk by British mine in English Channel 25.3.1917, Lassoo was mined or torpedoed by German submarine off Maass lightship 13.8.1916. Louis was wrecked 31.10.1915 in Dardanelles (Suvla Bay) and demolished by Turkish coastal artillery.
