the centuries. Twelve supply officers and one logistics officer rose to the rank of substantive vice-admiral (see list of admirals below), of whom two were further promoted to admiral; two others were promoted to acting/vice-admiral in the late 1940s. In recent decades, among the officers of flag rank in the Royal Navy, at any one time one, two or three supply officers have been rear-admirals. One of these two-star officers is appointed chief naval supply and secretariat officer (CNSSO) – now CNLO – as head of branch; however, there was no admiral in the Logistics Branch from 2008–2010 and the senior officer branch was a commodore. Rear-admiral David Steel, a barrister, was promoted to two-star rank on 20 April 2010 and became naval secretary and chief naval logistics officer (CNLO); he was promoted to vice-admiral in October 2012 on becoming Second Sea Lord, only the second officer from the branch to hold that post. A commander of the Royal Naval Reserve (RNR) is head of the RNR Logistics Branch. Women Women officers in the Women's Royal Naval Service (WRNS) would often serve ashore as a captain's secretary but rarely as a supply officer. After the disbanding of the WRNS in 1993, women were fully integrated into the Royal Navy's supply branch, with the wearing of gold stripes instead of blue stripes; for female naval supply officers, service at sea, as well as ashore, started to become the norm. Indeed, Commodore Carolyn Stait OBE FCIPD was the naval base commander, Clyde in from 2004 to 2007. Defence Maritime Logistics School, RN Logistics School and RN Supply School – history The present Defence Maritime Logistics School (DMLS) (see ), (until September 2006 the Royal Naval Logistics School (RNLS)) – the alma mater of Logistics Officers and ratings – is a lodger unit within HMS Raleigh in Torpoint, Cornwall PL11 2PD. Functionally however, the school exists as a 'franchise' of the Defence College of Logistics and Personnel Administration, whose headquarters reside in Deepcut, Surrey. The Commandant of the DMLS is Commander Suzi Nielsen RN. From 1 April 1958 to 1983 the RN Supply School (RNSS) was in HMS Pembroke, Chatham, Kent ME4 4UH. Previously the RNSS was in Thorp Arch, Wetherby, Yorkshire, the training establishment being known as HMS Ceres from 1 October 1946 to 31 March 1958 (see and ) and before that as HMS Demetrius, which had commissioned on 15 July
