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 Ministry of Defence is a ministerial department of the Government of the United Kingdom. It is responsible for implementing the defence policy set by the government and serves as the headquarters of the British Armed Forces.
The secretary of state for defence, also known as the defence secretary, is a secretary of state in the Government of the United Kingdom, with responsibility for the Ministry of Defence. As a senior minister, the incumbent is a member of the Cabinet of the United Kingdom.
The First Sea Lord and Chief of the Naval Staff (1SL/CNS) is a statutory position in the British Armed Forces, usually held by an 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 Admiralty Board is the body established under the Defence Council of the United Kingdom for the administration of the Naval Service of the United Kingdom.

The Defence Council of the United Kingdom is the supreme governing body of the British Armed Forces.

The Director of Naval Construction (DNC) also known as the Department of the Director of Naval Construction and Directorate of Naval Construction and originally known as the Chief Constructor of the Navy was a senior principal civil officer responsible to the Board of Admiralty for the design and construction of the warships of the Royal Navy.

The Board of Admiralty (1628–1964) was established in 1628 when Charles I put the office of Lord High Admiral into commission. As that position was not always occupied, the purpose was to enable management of the day-to-day operational requirements of the Royal Navy; at that point administrative control of the navy was still the responsibility of the Navy Board, established in 1546. This system remained in place until 1832, when the Board of Admiralty became the sole authority charged with both administrative and operational control of the navy when the Navy Board was abolished. The term Admiralty has become synonymous with the command and control of the Royal Navy, partly personified in the Board of Admiralty and in the Admiralty buildings in London from where operations were in large part directed. It existed until 1964 when the office of First Lord of the Admiralty was finally abolished and the functions of the Lords Commissioners were transferred to the new Admiralty Board and the tri-service Defence Council of the United Kingdom.
