The Vault would first be occupied on the day of the Great War, the meager first warning and remoteness of the Vault only allowed just over 200 people to enter before the door was sealed.

Once completed, it would be fully stocked with provisions and equipment, the only notable exception would be light-switches in a setion of the living quarters. It would cost four billion more than originally budgetted due to a shifting sedimentary layer not found in the original geological survey. Work on Vault 50 began on October 2nd, 2066, and ran almost seven years.
