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.
Volunteer Cadet Corps
The Royal Naval Volunteer Cadet Corps was formed in 1904 when the officer in charge of HMS Victory barracks in Portsmouth, now known as HMS Nelson, requested permission from Commander-in-Chief, Portsmouth to form a cadet corps unit similar to the Royal Marines Artillery Cadets in Eastney. The Admiralty granted permission and soon units were also established at HM Dockyard Devonport, HM Dockyard Chatham, , HMS "Daedalus", and , as well as the three RNVCC units that still exist today. Entry was originally restricted to the sons of serving ratings but was later opened up to boys and girls from the general public. The date of the request, 29 July 1904, is regarded as the birthday of the Royal Naval Cadets.
