The Admiralty was a department of the Government of the United Kingdom responsible for the command of the Royal Navy until 1964, historically under its titular head, the Lord High Admiral – one of the Great Officers of State. For much of its history, from the early 18th century until its abolition, the role of the Lord High Admiral was almost invariably put "in commission" and exercised by the Lords Commissioner of the Admiralty, who sat on the governing Board of Admiralty, rather than by a single person. The Admiralty was replaced by the Admiralty Board in 1964, as part of the reforms that created the Ministry of Defence and its Navy Department.
The First Sea Lord and Chief of the Naval Staff (1SL/CNS) is a statutory position in the British Armed Forces usually held by a four star admiral. As the highest-ranking officer to serve in the Royal Navy, the chief is the principal military advisor on matters pertaining to the navy and a deputy to the Secretary of State for Defence. In a separate capacity, the CNS is a member of the Chiefs of Staff Committee and, thereby, a military advisor to the National Security Council, the prime minister and the monarch. The First Sea Lord is typically the highest-ranking officer on active duty of the Royal Navy unless the Chief of the Defence Staff is a naval officer. Admiral Ben Key was appointed First Sea Lord in November 2021.
The Second Sea Lord and Deputy Chief of Naval Staff is deputy to the First Sea Lord and the second highest-ranking officer to currently serve in the Royal Navy and is responsible for personnel and naval shore establishments. Originally titled Second Naval Lord in 1830, the post was restyled Second Sea Lord in 1904. They are based at Navy Command, Headquarters.
The post of Controller of the Navy was originally created in 1859 when the Surveyor of the Navy's title changed to Controller of the Navy. In 1869 the controller's office was abolished and its duties were assumed by that of the Third Naval Lord whose title then changed to Third Naval Lord and Controller of the Navy. In 1904 the title was changed again to Third Sea Lord and Controller of the Navy. In 1965 the office of the Third Sea Lord was abolished. The post-holder is responsible for procurement and matériel in the British Royal Navy.
The Navy Board was the commission responsible for the day-to-day civil administration of the Royal Navy between 1546 and 1832. The board was headquartered within the Navy Office.
The Commander-in-Chief Fleet (CINCFLEET) was the admiral responsible for the operations of the ships, submarines and aircraft of the British Royal Navy from 1971 until April 2012. The post was subordinate to the First Sea Lord, the professional head of the Naval Service. In its last years, as the Navy shrank, more administrative responsibilities were added.
The Fifth Sea Lord was formerly one of the Naval Lords and members of the Board of Admiralty that controlled the Royal Navy. The post's incumbent had responsibility for naval aviation.
The Channel Fleet and originally known as the Channel Squadron was the Royal Navy formation of warships that defended the waters of the English Channel from 1854 to 1909 and 1914 to 1915.

The Admiralty and Marine Affairs Office (1546–1707), previously known as the Admiralty Office (1414–1546), was a government department of the Kingdom of England, responsible for the Royal Navy. First established in 1414 when the offices of the separate Admiral of the North and West were abolished and their functions unified under a single centralised command, it was headed by the Lord High Admiral of England. The department existed until 1707 when England and Scotland united to form the Kingdom of Great Britain, after which it was known as the British Admiralty.
During the early 17th century, England's relative naval power deteriorated; in the course of the rest of the 17th century, the office of the Admiralty and Marine Affairs steered the Navy's transition from a semi-amateur Navy Royal fighting in conjunction with private vessels into a fully professional institution, a Royal Navy. Its financial provisions were gradually regularised, it came to rely on dedicated warships only, and it developed a professional officer corps with a defined career structure, superseding an earlier mix of sailors and socially prominent former soldiers.
The Glorious Revolution of 1688 rearranged the political map of Europe, and led to a series of wars with France that lasted well over a century. This was the classic age of sail; while the ships themselves evolved in only minor ways, technique and tactics were honed to a high degree, and the battles of the Napoleonic Wars entailed feats that would have been impossible for the fleets of the 17th century. Because of parliamentary opposition, James II fled the country. The landing of William III and the Glorious Revolution itself was a gigantic effort involving 100 warships and 400 transports carrying 11,000 infantry and 4,000 horses. It was not opposed by the English or Scottish fleets.
The Admiralty War Staff was the former senior naval staff operational planning organisation within the British Admiralty that existed from 1912 to 1917. It was instituted on 8 January 1912 by Winston Churchill in his capacity as First Lord of the Admiralty and was in effect a war council whose head reported directly to the First Sea Lord. After the First World War ended, the War Staff was replaced by the Admiralty Naval Staff department.
The Admiralty Naval Staff was the former senior command, operational planning, policy and strategy department within the British Admiralty.

The Naval Stores Department also known as the Department of the Director of Naval Stores was initially a subsidiary department of the British Department of Admiralty, then later the Navy Department responsible for managing and maintaining naval stores and the issuing of materials at naval dockyards and establishments for the building, fitting and repairing of Royal Navy warships from 1869 to 1966.
The Department of the Director of Dockyards, also known as the Dockyard Branch and later as the Dockyards and Fleet Maintenance Department, was the British Admiralty department responsible from 1872 to 1964 for civil administration of dockyards, the building of ships, the maintenance and repair of ships at dockyards and factories, and the supervision of all civil dockyard personnel.
In 1989 the Royal Navy was under the direction of the Navy Department in the UK Ministry of Defence. It had two main commands, CINCFLEET and Naval Home Command.
