Von Braun's 1950s vision of near Earth space was one that included what amount to ICBMs going to space stations, emptying in the process, then being refuelled and sent on their way to the Moon or Mars for eventual breakdown as scrap, with space taxis taking people back down to the Earth. Soon after that he came up with what amounts to a space shuttle / space taxi and that cool looking nonaerodynamic Mars Mission main spacecraft - the nuclear one which is spheres stuck together.
ICBMs as quick and dirty spaceships is a great idea for cargo. I think that's what the semi commercial / semi military Athena series is for.
