Item #: SCP-XXXX

Object Class: Keter

Special Containment Procedures: SCP-XXXX and all contaminated materials are to be stored in a liquid helium bath containment vessel. The containment vessel is to be monitored for temperature; a reading of higher than 4.2 Kelvin is to be considered a Code Orange (Containment Breach Likely). This containment vessel is to be maintained in a containment chamber with an inert gas environment.

Under no circumstances are the following materials to be permitted within the containment chamber:

  • Carbon or any organic compounds.
  • Aluminium or any alloys constructed from Al. Aluminium oxide (Al2O3) is a confirmed threat.
  • Boron or any alloys constructed from B. Boron nitride (BN) is a confirmed threat.
  • Titanium or any alloys constructed from Ti. Titanium carbide (TiC) is a confirmed threat.

A nuclear failsafe mechanism with a yield no lower than 20 kt is to be kept no further than three meters from SCP-XXXX. The failsafe is to be armed in the event of a Code Orange and detonated immediately in the event of a Code Red (Containment Breach In Progress).

SCP-XXXX must be stored at a facility located at least fifty kilometers from the nearest fossil fuel deposit and population center.

Description: SCP-XXXX consists of two parts, though evidence suggests at least three identical sets of these parts exist.

SCP-XXXX-A is a hollow tungsten and titanium carbide cylinder 31.7 cm in length, 4.3 cm in external diameter, 2.9 cm in internal diameter. There is a seam bisecting the cylinder lengthwise; analysis suggests the cylinder is meant to open when it impacts a target at high velocity. Though SCP-XXXX-A's origins have not been ascertained at this time, the object shows no anomalous properties. At present, two cylinders (designated -A01 and -A02) are known to exist, with a third (designated -A03) believed but not confirmed to exist.

SCP-XXXX-B consists of 209.385 cubic centimeters of self-replicating nanomachines constructed of a variety of alloys, including aluminium oxide, boron nitride, and titanium carbide. Analysis of the nanomachines indicates they contain two base directives: convert hydrocarbons to carbon dioxide and water through combustion, and utilize the energy released from this reaction and available elements from the surrounding environment (especially Al, B, C, N, and Ti) to construct more of themselves. Foundation research indicates that SCP-XXXX-B is capable of inducing combustion in anoxic environments, apparently creating O2 in defiance of the law of conservation of matter.

SCP-XXXX-A01 was discovered in ████████, Krasnoyarsk Krai, Russian Soviet Federative Socialist Republic by the 13th Chief Directorate (Paranormal Investigations) of the Committee for State Security. The cylinder shows some damage from extreme heat and kinetic impact; this damage apparently sealed the cylinder and prevented its opening. The Foundation obtained the object in 1991 following the KGB's breakup.

The American Federal Bureau of Investigation's Unusual Incidents Unit (UIU) recovered the opened remains of another identical cylinder in ███████, New Mexico, United States of America; this item was subsequently confiscated by the Foundation and designated SCP-XXXX-A02. The object shows some damage from extreme heat and kinetic impact; however, it appears to have opened as designed. This cylinder was subsequently shown to have no trace of SCP-XXXX-B.

Unconfirmed intelligence reports suggest the Iranian Army of the Guardians of the Islamic Revolution may be in possession of a third such cylinder (provisionally designated SCP-XXXX-A03). The condition of this cylinder and state of its contents (if any) are unknown at this time.
