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
This structure of administering the navy lasted for 285 years, however, the supply system was often inefficient and corrupt its deficiencies were due as much to its limitations of the times they operated in. The various functions within the Admiralty were not coordinated effectively and lacked inter-dependency with each other, with the result that in 1832, Sir James Graham abolished the Navy Board and merged its functions within those of the Board of Admiralty. At the time this had distinct advantages; however, it failed to retain the principle of distinctions between the Admiralty and supply, and a lot of bureaucracy followed with the merger.
