Admiralty
It evolved from *Admiralty Navy War Council, (1909–1912) which in turn became the Admiralty War Staff, (1912–1917) before finally becoming the Admiralty Naval Staff in 1917. It was the former senior command, operational planning, policy and strategy department within the British Admiralty. It was established in 1917 and existed until 1964 when the department of the Admiralty was abolished, and the staff departments function continued within the Navy Department of the Ministry of Defence until 1971 when its functions became part of the new Naval Staff, Navy Department of the Ministry of Defence.
Fleet Air Arm
British naval flying started in 1909, with the construction of an airship for naval duties. In 1911 the Royal Navy graduated its first aeroplane pilots at the Royal Aero Club flying ground at Eastchurch, Isle of Sheppey under the tutelage of pioneer aviator George Bertram Cockburn. In May 1912, naval and army aviation were combined to become the Royal Flying Corps (RFC). The Naval Wing of the RFC lasted until July 1914 when the Royal Navy reformed its air branch, under the Air Department of the Admiralty, naming it the Royal Naval Air Service (RNAS).
