'''British re-armament''' was a period in British history, between 1934 and 1939, when a substantial programme of re-arming the {{wipe|United Kingdom}} was undertaken. Re-armament was deemed necessary, because defence spending had gone down from £766 million in 1919–20, to £189 million in 1921–22, to £102 million in 1932.<ref>Paul Kennedy, ''The Realities behind Diplomacy''. Fontana, 1981. p. 231.</ref>

==Ten Year Rule==
After [[Social:World War I|World War I]], dubbed "The War To End All Wars” and “The Great War”, Britain (along with many other nations) had wound down its military capability. The Ten Year Rule said that a "great war" was not expected in the next ten years with the belief in its impossibility and the folly of preparing for it. Britain, therefore, made almost no investment at all in the development of new armament.<ref name=":0">{{Cite book|title=Leadership in International Relations: The Balance of Power and the Origins of World War II|url=https://archive.org/details/leadershipintern00roth|url-access=limited|last=Roth|first=Ariel Ilan|publisher=Palgrave Macmillan|year=2010|isbn=9781349290369|location=New York|pages=[https://archive.org/details/leadershipintern00roth/page/n66 54]}}</ref> The British Admiralty, however, requested the suspension of this rule when Japan invaded Manchuria in 1931.<ref name=":0" /> The policy was officially abandoned on 23 March 1932 by the Cabinet,<ref name=":1">{{Cite book|title=Incidents and International Relations: People, Power, and Personalities|last=Kennedy|first=Greg|last2=Neilson|first2=Keith|publisher=Praeger|year=2002|isbn=0275965961|location=Westport, CT|pages=123}}</ref> four months before Adolf Hitler's [[Social:Nazi Party|Nazis]] became the largest party in the German Reichstag. A statement released cautioned that the decision was not an endorsement of increased armament spending, citing the grave economic situation in Britain and also indicating the British commitment to the arms limitations being promoted by the World Disarmament Conference, an event coinciding with the announcement.<ref name=":1" />

There are sources who describe the British re-armament immediately after the abrogation of the Ten Year Rule as uncertain, hovering between disarmament and re-armament.<ref name=":2">{{Cite book|title=A Guide to the Sources of British Military History|last=Higham|first=Robin|publisher=Routledge|year=2015|isbn=9781317390213|location=London|pages=453}}</ref><ref>{{Cite book|title=Military Effectiveness: Volume 2, The Interwar Period|last=Millett|first=Allan|last2=Murray|first2=Williamson|publisher=Cambridge University Press|year=2010|isbn=9780521425896|location=Cambridge|pages=101}}</ref> Even after the collapse of the League of Nations in 1935, the re-armament policy had been tempered by [[Social:Appeasement|appeasement]].<ref name=":2" />

==Collapse of international disarmament==
Germany was not considered a threat during the 1920s, but the situation changed radically when Hitler came to power in 1933 and withdrew Germany from the League of Nations and the Geneva Disarmament conference.

In October 1933, when the failure of the Disarmament Conference was evident, a Defence Requirements Sub-Committee of the Committee of Imperial Defence was appointed to examine the worst deficiencies of the armed forces. The group first considered the [[Place:Far East|Far East]], but soon looked at dangers nearer home.<ref>{{cite book |last= Rhodes James |first= Robert | title= Churchill: A Study in Failure, 1900-1939 |year= 1970 |publisher= Weidenfeld & Nicolson |location= London |isbn=978-0-297-17944-3 |page= 226 }}</ref>

==Re-armament==
Government-backed "Shadow Factories", generally privately owned but subsidised by the government, were established to increase the capacity of private industry; some were also built by the government. Similarly, Agency Factories supplemented the Royal Ordnance Factories.

===Royal Air Force===
In 1918 the newly formed Royal Air Force had 290,000 personnel and around 23,000 aircraft.<ref>https://www.raf.mod.uk/our-organisation/our-history/#:~:text=The%20'new'%20RAF%20was%20the,in%20support%20of%20ground%20forces.</ref>

In the mid-1930s, the {{wipe|Royal Air Force}}'s front-line fighters were biplanes, little different from those employed in World War I. The re-armament program enabled the RAF to acquire modern [[Engineering:Monoplane|monoplane]]s, like the [[Engineering:Hawker Hurricane|Hawker Hurricane]] and [[Engineering:Supermarine Spitfire|Supermarine Spitfire]], such that  sufficient numbers were available to defend the UK in the Battle of Britain in 1940, during the early stages of [[Social:World War II|World War II]].

===Royal Navy===
Re-armament also led to the Royal Navy acquiring five new [[Engineering:Battleship|battleship]]s of the ''King George V'' class, and modernising existing battleships to varying extents.  Whereas ships such as {{HMS|Renown|1916|6}} and {{HMS|Warspite|03|6}} were completely modernised, others such as {{HMS|Hood|51|6}}, the ''Nelson'' class, the ''Royal Sovereign'' class, HMS ''Barham'', and HMS ''Repulse'' were largely unmodernised - lacking improvements to horizontal armour, large command towers and new machinery.

Equally importantly, [[Engineering:Aircraft carrier|aircraft carrier]]s of the ''Illustrious'' class and a series of large cruiser classes were ordered and expedited. Britain also accelerated building programmes such as the Singapore Naval Base, which was completed within three and a half years instead of five.<ref name=":1" />

===British Army===
The British Army was supplied with modern tanks and weapons, for example howitzers, and the Royal Ordnance Factories were equipped to produce munitions on a large scale.
