Arnott's once again turned production to support the Australian war effort in the 1940s, while also supplying C-rations to the U.S. forces. During this period, the company dropped most of its biscuit, cake, and cookie varieties, trimming down to just under 20 brands, although these included such company mainstays as the Iced Vo Vo and the SAO. With the end of the war, Arnott's resumed full-scale production for the consumer market, although initial production had by then dropped to just 12,500 tons per year.
