OWM

Abbreviation of the U.S. World War II-period agency,  the Office of War Mobilization, which was established in 1943 to coordinate all government agencies involved in the war effort. This agency took over from the earlier War Production Board  (WPB) to shift the nation from a peacetime to a wartime economy.

In 1944, the OWI was succeeded by the Office of War Mobilization and Reconversion, whose mandate was to coordinate both wartime and postwar economic planning. In 1945, it took on the functions of the Office of Economic Stabilization as well.
