The first independent air force, the Royal Air Force, was formed on 1 April 1918 during the First World War. It was a merger of the Royal Flying Corps and the Royal Naval Air Service. Its leaders and personnel brought cultural predispositions with them from their former services. Unsurprisingly, many aspects of the new independent Service that they created were similar to those in the Royal Navy and British Army. Despite that, a distinctive RAF culture emerged within a short time frame. Many elements of that culture have subsequently been emulated by other nations as they formed their own independent air forces. Those who serve or have served in the RAF intuitively know the power of its culture. RAF life is an immersive experience that evokes a range of assumptions, beliefs and emotions that can deeply affect combat performance. Despite this, little academic study of RAF culture has been conducted. This thesis will examine the history of the RAF from a new social angle. It will establish why its culture is so important and why RAF culture became so distinctive given its very traditional foundations.
