Vault 52

The fallout shelter that would go on to be renovated and designated Vault 52 was originally constructed in 2054, five years prior to the construction of the LA Demonstration Vault. Originally part of “Project: Safehouse” it was designated as Safehouse 8. The plan was to build one Safehouse for each Commonwealth and the project became one of the earliest collaborations between the U.S. government and the Vault-Tec Corporation.

Safehouse 8 was a 50,000 sq foot shelter built inside the Springfield Underground commercial facility, a limestone quarry that tapped out in late 2020. The facility was located east of Interstate 44 and south of US Route 65 in Springfield, MO.

Halfway through construction of the 125 shelters originally ordered, Vault-Tec executives knew they wouldn’t be able to fill the order. It was determined to be cheaper to renovate the thirteen old Project: Safehouse shelters, designate them official Vault-Tec Vault facilities, and artificially inflate their numbers. Vaults 45 to 57 were former Project: Safehouse bunkers.

The biggest difference was in the size. The government contract required a one thousand person capacity per vault, but Project:Safehouse shelters were only built for a hundred people. When the final reports were turned in, Vault-Tec reported the entire five million square feet of the Underground as the Vault size. As such, the Government assigned nine-hundred people to a Vault that can’t possibly hold them all.
