As stated in a past article, government spending on NASA as a percentage of the economy peaked during the middle of the Apollo years at almost 0.8%. However, it recently struck me out of the blue that the Apollo program spending must have been matched by the "real" space race with the Russians -- that of nuclear ICBMs. In 1990, the U.S. had about 1,000 ICBMs (of the smaller, solid-fueled variety of ICBMs).
The differences between launch vehicles and ICBMs of the Apollo era is not that great, except that ICBMs tend to be relatively modestly sized compared to some of the large manned platforms like the Saturn V. For instance, the Russians are converting the SS-18 (Satan) ICBMs into Dnepr launch vehicles -- a real swords to plowshares story -- that has the capacity roughly of the Delta II launch vehicle.
I would be interested in sources of information on government spending over time for ICBMs, if you have them.
