I hear the Atlas E type bases are the best. The Atlas E’s were stored horizontally and their bases have a giant “sarcophagus” instead of a useless silo.
That’s correct. I used to spend hours (ahem) “exploring” these sites, and they are rather awesome. The Atlas skin was too thin to be self-supporting so the ground support equipment included, in addition to all the fuel and oxidizer pumping and storage apparatus, nitrogen pressurization to make the thing stiff enough that it could be raised into firing position. The top of the site was made like a roll-top so it could be moved out of the way. The crew quarters and LCF are probably bigger than an average house and the rest of the facility makes like a 20-car garage.
