The base is basically a modified TerrorDrome. It always looked more like an underwater base or space station to me, so I took a badly yellowed one with horrible discolored parts, and customized it. :) I wanted a glass top, while retaining the functional iris, so hand shaped Plexiglas pieces. The new decals and weathering, was a family affair, thus the multiple names in the who's responsible area. :) In our Joe verse the Brotherhood of Steel in a major faction, thus the B.O.S. symbols. We figured this is one of their hidden bases.
