The Vault-Tec terminal in the Citadel lists Vault 76 as a "control" vault, with 500 occupants. The vault was designed to open after 20 years. It was among the seventeen known control vaults, meaning that it was used as a baseline to compare to experimental vaults. It is also mentioned in one of the alien captive recorded logs (no.13) recorded by Giles Wolstencroft, a Vault-Tec official who was abducted while inspecting the vault's construction site.
