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 Experiment Works
The Admiralty Experiment Works (AEW) was the British Admiralty research establishment, responsible for improving propeller design, manoeuvrability and seakeeping in Royal Navy vessels. The Experiment Works existed from 1872 to 1977 and for most of its history was based at the Haslar Gunboat Yard in Gosport, South Hampshire. It ceased independent operations in 1977, merging with the Admiralty Marine Technology Establishment and ultimately with the Defence Research Agency in the Ministry of Defence.
