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.
Admiralty Interview Board
The Admiralty Interview Board (AIB) 
is an assessment centre, founded by Admiral Sir John Fisher in 1905, that is used by the Naval service as part of the officer selection process for the Royal Navy, Royal Marines, Royal Naval Reserve, Royal Marines Reserve, and Royal Fleet Auxiliary. It is an equivalent of the Army Officer Selection Board and the Officer and Aircrew Selection Centre of the Royal Air Force. The board is based at HMS "Sultan" in Gosport, Hampshire within a self-contained compound.
