Pictured: Building 110, Vertical Assembly Building (1) (yes, there’s another VAB on site at Michoud Assembly Facility), Front Left Cell A where, I think, the LH2 (liquid Hydrogen) tank will be mated to the Intertank, which is the component that interconnects the LH2 tank with the LO2 tank. Back Left, former location of cells B and C, now the Vertical Weld Tool. In the picture, the L02 tank is in the tool. The LH2 tank consists of 5 Barrel Sections to the L02 tank’s 2.

Right side: Stuff that won’t be used in this program, I think.

Background: bldg 114, also known as the high bay. I’m not sure if those cells are used in the SLS program.

Large acreage foam sprays used to be conducted in these two buildings during the shuttle program, but due to the length of the SLS components they will not readily accommodate those components. I’m not in the production side of things, but I think that the primer and foam application steps will be conducted in bldg 131, which was lengthened by 50 feet to accomodate SLS. Before priming and foam happens, both tanks have to be pressure tested, which, for the LO2 tank, entails filling the thing up with water, and the LH2 tank gets filled with Gaseous Nitrogen (GN2).
