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.
Chemical Department (Royal Navy)
The Admiralty Chemical Department, Portsmouth, originated in the appointment of an Admiralty Chemist in 1867. In 1870 as the work of the ADMC was expanding led to the creation of a department with supporting researchers and clerical staff being established. In 1956 specific functions of the Central Metallurgical Laboratory transferred to the department when it was re-styled as the Central Dockyard Laboratory. In 1977 it merged with Admiralty Marine Technology Establishment but remained a sub-division of that organisation. It provided Support Services for fleet and shore establishments, including metallurgy, chemistry, biology, paint technology and reactor chemistry research.
