Birth of the Royal Australian Air Force Appointed an
Officer of the Order of the British Empire in the
1919 New Year Honours, Williams served as Staff Officer, Aviation, at
Australian Imperial Force (AIF) headquarters in London, before returning to Australia and taking up the position of Director of Air Services at Army Headquarters,
Melbourne. The
Australian Flying Corps had meanwhile been disbanded and replaced by the
Australian Air Corps (AAC) which was, like the AFC, a branch of the
Army. Upon establishment of the
Australian Air Board on 9 November 1920, Williams and his fellow AAC officers dropped their army ranks in favour of
those based on the Royal Air Force. Williams, now a
wing commander, personally compiled and tabled the Air Board's submissions to create the Australian Air Force (AAF), a service independent of both the Army and the
Royal Australian Navy. The AAF was duly formed on 31 March 1921; Williams deliberately chose this day rather than 1 April, the founding date of the RAF three years earlier, "to prevent nasty people referring to us as 'April Fools'". The "Royal" prefix was added five months later. Williams proposed an
ensign for the AAF in July 1921, based on the
Royal Air Force flag but featuring the five stars of the
Southern Cross within the RAF
roundel and the
Commonwealth Star in the lower hoist quarter. This design was not adopted for the RAAF, the government employing instead a direct copy of the RAF ensign until 1949, when a new design using the stars of the
Australian flag was chosen. As the senior officer of the Air Board, Williams held the title of First Air Member, the nascent Air Force initially not being deemed suitable for a "Chief of Staff" appointment equivalent to the Army and Navy. He moved to consolidate the new service's position by expanding its assets and training. Shortly after the AAF's establishment, land was purchased for an air base at
Laverton, eight kilometres (five miles) inland of Point Cook, and in July 1921 Williams made the initial proposal to develop a base at
Richmond, New South Wales, the first outside Victoria. He also started a program to second students from the Army and Navy, including graduates of the
Royal Military College, Duntroon, to bolster officer numbers; candidates reaped by this scheme included future Air Force chiefs
John McCauley,
Frederick Scherger,
Valston Hancock and
Alister Murdoch, along with other senior identities such as
Joe Hewitt and
Frank Bladin.
Chief of the Air Staff The position of First Air Member was replaced by
Chief of the Air Staff (CAS) in October 1922. Williams would serve as CAS three times over seventeen years in the 1920s and '30s, alternating with Wing Commander (later Air Vice Marshal)
Stanley Goble. One motive suggested for the rotation was a ploy by Army and Navy interests to "curb Williams' independence". Instead the arrangement "almost inevitably fostered an unproductive rivalry" between the two officers. Williams spent much of 1923 in England, attending the
British Army Staff College in Camberley and
RAF Staff College, Andover, followed by further study in Canada and the United States the following year. Goble served as Chief of the Air Staff in his absence. Shortly after his return in February 1925, Williams scuppered a plan by Goble to establish a small
seaplane base at
Rushcutters Bay in Sydney, instead organising purchase of
Supermarine Seagulls, the RAAF's first
amphibious aircraft, to be based at Richmond. He was promoted to
group captain in July and later that year drafted a major air warfare study,
"Memorandum Regarding the Air Defence of Australia". Considered prescient in many ways, it treated World War I ally
Japan as Australia's main military threat, The young Air Force was a small organisation with the atmosphere of a
flying club, although several pioneering flights were made by its members. Goble had commanded the first
circumnavigation of Australia by air in 1924 while he was CAS. On 25 September 1926, with two crew members including Goble's pilot,
Ivor McIntyre, Williams commenced a round trip from Point Cook to the
Solomon Islands in a
De Havilland DH.50A
floatplane, to study the South Pacific region as a possible theatre of operations. The trio returned on 7 December to a 12-plane RAAF escort and a 300-man honour guard. Though seen partly as a "matter of prestige" brought on by contemporary newspaper reports that claimed "'certain Foreign Powers'" were planning such a journey, and also as a "reaction" by Williams to Goble's 1924 expedition, it was notable as the first international flight undertaken by an RAAF plane and crew. and promoted to
air commodore on 1 July the same year. Williams again handed over the reins of CAS to Goble in 1933 to attend the
Imperial Defence College in London, resuming his position in June 1934. His promotion to
air vice marshal on 1 January 1935 belatedly raised him to the equivalent rank of his fellow Chiefs of Staff in the Army and Navy. Williams encouraged the local aircraft industry as a means to further the self-sufficiency of the Air Force and Australian aviation in general. He played a personal part in the creation of the
Commonwealth Aircraft Corporation in November 1936, headed up by former
Squadron Leader Lawrence Wackett, late of the RAAF's Experimental Section. In 1939 Williams was dismissed from his post as CAS and "effectively banished overseas", following publication of the Ellington Report that January. The Federal government praised Williams for strengthening the Air Force but blamed him for Ellington's findings, and he was criticised in the press. Beyond the adverse report, Williams was thought to have "made enemies" through his strident championing of the RAAF's independence. The government announced that it was seconding him to the RAF for two years. ==World War II==
