Which body oversees the administrative affairs of the RAF?

The Royal Air Force Board is the correct body that oversees the administrative affairs of the RAF. This board is responsible for the strategic management and governance of the Royal Air Force as a whole, ensuring that it operates effectively and efficiently. It encompasses senior leadership from both military and civilian backgrounds, which allows for a comprehensive approach to decision-making and oversight of policies that affect the service.

The Ministry of Defence plays a broader role in the UK's defense policy and administration, overseeing all branches of the armed forces, including the RAF, but it does not manage the internal administrative functions specific to the RAF itself. Similarly, the General Staff Committee is more focused on operational and strategic military issues rather than internal administrative oversight. The Air Command Leadership Team, while involved in the leadership and operational management of the RAF, also does not take on the detailed administrative oversight functions that are the purview of the Royal Air Force Board.

In summary, the Royal Air Force Board uniquely specializes in handling the comprehensive administrative aspects, making it the authoritative body for these matters within the RAF.
