Admiralty type flotilla leader
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 contemporary with the Thornycroft type leader, distinguishable by their two narrow funnels of equal height, the Thornycroft designs latter having characteristic  broad, slab-sided funnels. 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 for an extra ½ knot. Ships in class.
