Bunker Theta B-8-0

Pre-War Use
Before the bombs fell, it was intended to be used to connect a global array of orbital missile satellites, however, it was quickly re-purposed as a fallout shelter for military officials when the first bombs fell. Only 2 officials made it to the bunker, but they however died.

Post-War Use
After the bombs, it remained sealed until the enclave marked it as a site to set up a new base. In 2278, after the loss of Adam's AFB, a large splinter cell of enclave outcasts made their way into the west. Once they were kicked out of the west by the NCR, they arrived back in the east, and took control of the bunker.
