Not necessarily. The way BTE Dan wanted, yes--but there is another way. I would go with two new build SHLLVs, one of them Sea Dragon--a very large pressure-fed rocket that would be cheaper because it uses shipyard technology, as opposed to aerospace tech; http://smg.photobucket.com/user/Masao/media/ConSeadragon.jpg.html One or two of its upper stages and you have a secondary hull--plus it would drop payload costs. The primary hull would simply be an empty Phil Bono saucer: http://www.astronautix.com/b/bonosaucer.html This design allows for flat--very wide payloads, like monolithic dishes we would need anyway. There was even a Shuttle-C design that looked a bit like the Enterprise: https://www.aiaa.org/uploadedFiles/...uttle_Launches/ShuttleVariationsFinalAIAA.pdf See page 6-7
