Many objects of interest in an integrated space program are large but not excessively massive. Examples include solar concentrator mirrors, radio dishes, optical mirrors, space station subassemblies, and aerocapture surfaces for large payloads. The program is greatly facilitated by an Earth launch vehicle which can place such objects, up to some size limit, at the Earth station in a single launch.

The design of such a vehicle is straightforward, provided the higher drag is viewed as an acceptable cost for the capability. The payload bay is 50 feet tall, 50 feet wide, and 20 feet thick. The two stages sit under it, and have horizontal rather than vertical tanks, so they are shaped more like freight cars. The vehicle is a "2+1" configuration, with a 20 ton payload weight. It uses many components in common with the basic freight vehicle.

Payloads which are too light can be "padded" with supplies for the station; these include fuel for various re-usable outer space vehicles.
