If the Boring Machines exist (they do), then there is absolutely no reason why we would not have entire submarine highways, docks and repair/maintenance facilities in fucking Nebraska. In fact, if I had those machines and I had an Atlantic Fleet that could find itself needing to get to the Pacific quickly to support the Pacific Fleet, I would consider building an underground submarine highway across the USA to be a matter of National Security. As in must have.
Water Island also allegedly has a submarine "facility"
Watch the water?
