The Admiralty type leader, sometimes known as the Scott class, were a class of eight destroyer leaders designed and built for the Royal Navy towards the end of World War I. They were named after Scottish historical leaders. The function of a leader was to carry the flag staff of a destroyer flotilla, therefore they were enlarged to carry additional crew, offices and signalling equipment, allowing a fifth gun to be carried. These ships were very similar to the Thornycroft type leader, but the latter had broad, slab-sided funnels characteristic of Thornycroft designs, the Admiralty type having two narrow funnels of equal height.

All except Mackay and Malcolm were completed in time for wartime service, Scott being a war loss. The two final orders - Barrington and Hughes - were cancelled with the end of the War; these two had originally been ordered to the Thornycroft leader design. Stuart was transferred to Australia in 1933. All the remaining ships except Bruce (expended as a target ship in 1939) survived service in World War II, being converted to escort ships. Montrose and Stuart had Brown-Curtis steam turbines, giving 43,000 shp (32,000 kW) for an extra ½ knot.

Ships

The prototype was ordered in April 1916 under the War Emergency Programme:

Scott; built by Cammell Laird & Company, Birkenhead, launched 18 October 1917 and completed 1918. Torpedoed by U-boat 15 August 1918 in the North Sea off the Dutch coast.

Two more were ordered in December 1916:

Five more were ordered in April 1917. The second vessel was originally named Claverhouse, but was renamed Mackay 31 December 1918:
