Since debuting Vault 76 last year, in honor of America's tercentenary, Vault-Tec continues to expand with plans for well over 100 Vaults around the country.”— Newscaster
Not all vaults were designed with experimental purposes. Vault 76 is one of seventeen known "control" vaults, meaning that it was used as a baseline to compare to experimental vaults. Vault 76 housed 500 occupants and was programmed to open to the wasteland outside 20 years after a nuclear war. According to the Vault-Tec Terminal in the Citadel, Vault 76 is located somewhere in Washington D.C., likely in the outskirts or outlying areas as it does not show up on the Capital Wasteland map.
Construction of Vault 76 began in 2065 and ended in 2069, under the supervision of Vault-Tec official Giles Wolstencroft. Vault 76 then debuted five years later in 2076, in honor of the United States's tercentenary when discussing Vault-Tec's plans to expand. The Vault is scheduled to reopen in 2097, twenty years after the events of the Great War.
