Patrick,

I've made some research and I only have been able to find the whole general budget of the US government prior to WWII and after WWII, but no precise cyphers on the military expenses…

But, if this is helpful, here is what Germany spent (cyphers are in billion Reichsmarks):

Military * Civil
1939-1940 * 38.0 * 20.0*
1940-1941 * 55.9 * 24.1*
1941-1942 * 73.3 * 28.2*
1942-1943 * 86.2 * 37.8*
1943-1944 * 99.4 * 30.6
