Singapore made fleet mobility a Far East strategy

Permanent deployment of the battle fleet in the Far East was unaffordable, so planners emphasized a defended Singapore base and improved refueling facilities along the route east. Keeping the main fleet in a central position such as the Mediterranean preserved the option to reinforce either Europe or Asia as events required. British planners treated a future American-Japanese war as a serious contingency whose fallout Britain might have to manage. A strong base let the government delay showing its hand, whereas sending a fleet early because facilities were inadequate could itself appear provocative to Japan. The strategy therefore joined logistics to diplomacy: fuel and repair capacity created political freedom of action as well as naval reach.
