Project history

The boats of the 1913-14 Programme were improved 'L's, wilh 6kts more speed, at the insistence of the new First Lord of the Admiralty, Winston Chutthill. For the first time speed of delivery was all-important, as the Admiralty clearly recognised that war was imminent, and Thornycroft, White and Yarrow were asked to accept two orders each, with the first payment to be made in April 1913, before contracts were signed (delivery was to be in March 1914). Thus when in March 1913 the Controller issued invitations to tender, the three boats building at Thornycroft and the two each at Yarrow and Hawthorn Leslie were 'bought' as if they had been built on speculation. Two orders planned for J S White were not placed, however, and Thornycroft were given a third order. Geared turbines were favoured, but the E-in-C wished to wait until the trials results with Leonidas and Lucifer were available before making the switch to the 'all-geared' type. Similarly longitudinal framing would be examined after Ardent had finished her trials.     Excluding the seven 'stock' boats already building, the final order was for only six, three from John Brown, two from Palmer and one from Swan Hunter, making 13 instead of the normal 20 for a full flotilla. The reason was that money for the Arethusa class light cruisers had used up funds in the current Estimates - a decision which was justified on the dubious grounds that they would take over many of the duties of destroyers. The lead boat, Miranda was begun in October 1912 and completed in August 1914, followed by her sisters in October-November. She made 33kts in deep load condition, whereas Minos in light condition made 36kts on a 6-hour trial. The 'M' class were generally similar to the 'L' class in appearance, but with the midships gun on the deck, not on a 'bandstand' platform. The Yarrow boats had two funnels and the bridge carried well back from the forecastle. The Hawthorn Leslie boats had four funnels. The Admiralty boats had short funnels, and the Thornycroft boats could be distinguished by three taller flat-sided funnels. The design proved most successful and, with only slight modifications, was used for mass-production in the war which followed.

Marksman, Menace and Monitor were projected for the 1914-15 Programme but were cancelled in favour of two Lightfoot class leaders.
