Containment Protocols:

RPC-468 material covering OL-Site 381 is to be left in place. All other instances of RPC-468 material are to be contained on-site at OL-Site-381 in Secure Locker 468. Access to RPC-468 for testing or any other purpose must receive prior written approval from the site director and project lead in writing and requires clearance level 2-468. Instances of RPC-468 are to be handled with care. Direct contact whilst in its charged state is to be strictly avoided as is long-term proximity.1

Description:

RPC-468 refers to a metamaterial which coats the exterior of OL-Site-381. Its chief effect is to render everything it covers completely invisible to the human eye and undetectable to instruments; the material itself only becomes visible under high levels of magnification.2

Recovered materials indicate that RPC-468 is constructed via femtotechnology, i.e. matter manipulation on the femtometer scale.3 Ordinary matter has a large amount of empty space in between the nucleus and the orbiting electrons. In instances of RPC-468, this empty space is somehow compressed so that it resembles degenerate matter.4

Testing has since demonstrated a secondary capability. When supplied with an electric charge of ███, the surface of the material becomes extremely resistant to the kinetic energy of projectiles and other incoming objects.

Whilst the exact threshold is currently unclear at this time, testing has shown that whilst slow-moving objects can still impact the material, objects moving at high speed are repelled whilst leaving the material itself undamaged. Projectiles that come into contact with RPC-468 in this manner are annihilated. The upper limit of this secondary ability has yet to be determined but is known to be somewhere below 3% light speed.

It is presently unknown why this secondary ability requires an electric charge to manifest or why these side effects occur. According to theoretical physics, such material should naturally possess incredibly high tensile strength. Moreover, it should also possess incredible levels of heat resistance, yet experimentation has shown instances of RPC-468 possess the same melting point as ordinary steel alloy.

Discovery:

RPC-468 was discovered along with RPC-381 on ██/██/████ in Loving County, TX, USA. Investigations that ultimately led to the discovery of RPC-381 naturally led to the discovery of OL-Site-381, the exterior of which being coated in RPC-468. The precise nature of RPC-468 was not immediately apparent but was deduced shortly after discovery of OL-Site-381 itself.

Whilst the region where OL-Site-381 was discovered has a particularly low population density6, some form of additional explanation as to how the site had avoided detection for so long was nevertheless needed as interior exploration revealed OL-Site-381 to be somewhere in the region of 4.16 sq km.

Study of removed samples have indicated that copyright information and a company logo are engraved on each individual panel of material.7 This was determined after those handling the material, who universally reported the material as being smooth to the touch, reported a series of indentations in one of the corners.

Plaster casts were then taken, and the text was then able to be read:

Efforts to reverse-engineer this material are ongoing. Use of this material for defensive and stealth purposes are also being researched at this time.
