An ad for the 'Living Shelters' America First model of fallout shelter, same as SCP-XXXX.
Special Containment Procedures: As of █/██/██ the land surrounding and directly above SCP-XXXX is to be monitored and controlled by Foundation personal. SCP-XXXX's location is to be scrubbed from local maps, and routes and roads that pass through SCP-XXXX's coordinates are to re-routed.
Furthermore, mentions of the 'Greeneberg' family are to be removed from history books, address registries and local government files. SCP-XXXX-A-E are to be classified as 'nonpersons', and are to have a record of their existence within Ladyville, Dallas are to be erased.
Documents that contain information about SCP-XXXX-A-E are to be seized and destroyed. SCP-XXXX's inner entrance does not need to be secured, as approximately two metric tons of earth and soil have blocked the entry-point.
Description: SCP-XXXX consists of a underground concrete fallout structure, along with a family that is enclosed inside of it.
Foundation schematics and testing have revealed that SCP-XXXX is 35 by 35 meters, with about 625 cubic meters of living space, and is approximately 12 meters underground. Exterior materials used in the construction of SCP-XXXX have been determined to consist mostly of galvanized concrete in the exterior wall, with an inner wall made up of concrete along with packed soil.1 R-F waves have determined that each material was around 13 centimetres thick, consistent with most bomb-shelters constructed in this time-period.
SCP-XXXX is currently located underneath a suburban house Ladyville, Dallas, Texas.. According to SCP-XXXX-B, the current location differs from the structure's original location, from about five kilometers away.
SCP-XXXX has been determined to be impervious to most forms of damage and outside forces. Giger counters used in close location to SCP-XXXX have reported unusually low RAD levels, suggesting that the structure is also immune to radioactive fallout. Further-more, SCP-XXXX's exterior walls are found to be impenetrable, with foundation drills, picks and other mining machinery unable to leave any damage to the structure. Because of this, removal of SCP-XXXX-A-E is un-feasible.2
According to SCP-XXXX-A, SCP-XXXX had existed in an alternate-universe in which the events of the Cuban Missile Crisis had reached a critical point, resulting in severe atomic war between the United States and The Soviet Union. Furthermore, SCP-XXXX is hypnotized to have been directly struck by a missile, causing the structure to be forced into an alternate dimension.3
SCP-XXXX A-E do not behave like standard humans, having no need to drink, sleep, or eat in order survive.
Furthermore, none of the SCP-XXXX members are able to age, or are able to increase cognitive abilities.4
