The SLS first stage is being built at the NASA Michoud Assembly Facility in New Orleans. This is the same facility that built the Saturn V first stage and also the Space Shuttle External Tanks. The Orion space capsule hulls are also fabricated at this facility then shipped to KSC for installation of all flight systems.The main building at Michoud was built for WWII aircraft production and also built engines for Patton tanks for the Korean war. It is over 40 acres under one roof and was constructed by the man who designed and built the WWII landing crafts; Andrew Higgins! The taxpayer got their money’s worth with this facility!!
