The Chief of the Air Staff (CAS) is the professional head of the Royal Air Force and a member of both the Chiefs of Staff Committee and the Air Force Board. The current Chief of the Air Staff is Air Chief Marshal Sir Stephen Dalton. He succeeded Air Chief Marshal Glenn Torpy as Chief of the Air Staff on 31 July 2009.^[1]

[edit] History

The post was established with the formation of the RAF in 1918, and its first occupant, Marshal of the Royal Air Force Sir Hugh Trenchard, was key in the establishment of the RAF as a separate service.

After Lord Trenchard retired in 1929 his successors had to fight to keep the RAF separate from the Royal Navy and the British Army, but Trenchard's foundations proved solid.

By the time World War II broke out in 1939, the then occupant of the post, Air Chief Marshal Sir Cyril Newall, had a service that had been undergoing the most rapid of expansions during the British rearmament programs of the late 1930s. Newall gave way in 1940 to Air Chief Marshal Sir Charles Portal, who led the service for the rest of the war. Portal was a tireless defender of the RAF and extremely able in administration and strategy.

Postwar the RAF was reoriented to perform the dual roles of defending the shrinking British Empire and possibly fighting against the Soviet Union in a Warsaw Pact verses NATO war over Germany and the United Kingdom. The Chiefs of the Air Staff of the day had to fight a constant battle to keep the British aircraft industry alive. In the end only minimal success was achieved, with only a rump aviation industrial base left by the 1970s.
