The Ministry of Defence (MOD or MoD) 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 MOD states that its principal objectives are to defend the United Kingdom of Great Britain and Northern Ireland and its interests and to strengthen international peace and stability. The MOD also manages day-to-day running of the armed forces, contingency planning and defence procurement.

The expenditure, administration and policy of the MOD are scrutinised by the Defence Select Committee, except for Defence Intelligence which instead falls under the Intelligence and Security Committee of Parliament.

History

During the 1920s and 1930s, British civil servants and politicians, looking back at the performance of the state during World War I, concluded that there was a need for greater co-ordination between the three services that made up the armed forces of the United Kingdom: the Royal Navy, the British Army and the Royal Air Force. The formation of a united ministry of defence was rejected by the coalition government of David Lloyd George in 1921, but the Chiefs of Staff Committee was formed in 1923, for the purposes of inter-service co-ordination. As rearmament became a concern during the 1930s, Stanley Baldwin created the position of Minister for Co-ordination of Defence. Ernle Chatfield, 1st Baron Chatfield held the post until the fall of the Chamberlain government in 1940. His success was limited by his lack of control over the existing Service departments, and his lack of political influence.

On forming his government in 1940, Winston Churchill created the office of Minister of Defence, to exercise ministerial control over the Chiefs of Staff Committee and to co-ordinate defence matters. The post was held by the Prime Minister of the day until Clement Attlee's government introduced the Ministry of Defence Act of 1946. After 1946, the three posts of Secretary of State for War, First Lord of the Admiralty, and Secretary of State for Air were formally subordinated to the new Minister of Defence, who had a seat in the Cabinet. The three service ministers – Admiralty, War, Air – remained in direct operational control of their respective services, but ceased to attend Cabinet.

From 1946 to 1964, five Departments of State did the work of the modern Ministry of Defence: the Admiralty, the War Office, the Air Ministry, the Ministry of Aviation, and an earlier form of the Ministry of Defence. Those departments merged in 1964, and the defence functions of the Ministry of Aviation Supply were merged into the Ministry of Defence in 1971. The unification of all defence activities under a single ministry was motivated by a desire to curb interservice rivalries and followed the precedent set by the American National Security Act of 1947.
