Royal Observer Corps
In 1929 the control of the Observer Corps passed from the county police forces to the Air Ministry, although Chief Constables retained responsibility for personnel and recruitment matters. 1 March 1929 saw the establishment of the new "Headquarters of the Observer Corps" at Hillingdon House, RAF Uxbridge in the west of London, and Air Commodore Edward A D Masterman CB CMG CBE AFC RAF (Rtd) was appointed as the first commandant of the Observer Corps. "Air Cdre" Masterman held this appointment until his retirement on 1 March 1936, and was succeeded by Air Commodore Alfred Warrington-Morris CG CMG OBE AFC RAF (Rtd), who would lead the Observer Corps through the critical period during the Second World War which saw the RAF emerge bruised but victorious following the Battle of Britain of 1940.
Commandant Royal Observer Corps
The organisation had started as the volunteer civilian Observer Corps in 1925 and became the uniformed Royal Observer Corps in 1941 as part of the RAF in recognition of their invaluable services during the Battle of Britain. Despite several attempts by the Home Office in the 1950s, 1960s and the 1980s to take over the organisation and dispense with the RAF uniform the ROC remained part of RAF Fighter Command and later RAF Strike Command until they were stood down in 1995 as a result of the Communist Bloc breaking up and the Cold War nuclear threat on the UK being removed.
