The engineering predecessor of SCP-4097, the Big Bertha howitzer.

Item #: SCP-4097

Object Class: Safe

Special Containment Procedures: SCP-4097 has been disguised as a construction site for an upcoming drilling rig placed upon an underground oil reservoir. Despite several failed civilian attempts to gain access SCP-4097, no further physical containment has been deemed necessary. Satellite footage or pictures of SCP-4097 are to be reviewed and edited if need be.

The testing of any of SCP-4097's ammunition via firing from SCP-4097 is to be fired at Test Site-4097 "Little 19". Requests to perform diagnostics on any of SCP-4097's ammunition are to be denied immediately due to the risk of accidentally destroying or detonating ammunition. Under no circumstance should any Foundation personnel be permitted to enter Magazine-12 without the permission of at least 1 Level-4 personnel. Foundation personnel wishing to spectate a test fire of SCP-4097 are prohibited from spectating outside of the set soundproof barriers.

Revision 13-b: The testing of any of SCP-4097's ammunition via firing from SCP-4097 has been temporarily suspended following Incident-4097-F-"Little 19". Diagnostics on SCP-4097 ammunition entities as well as entrance to Magazine-12 are not permitted, regardless of clearance level.

Description: SCP-4097 is a Tunisia-Sahara Class siege cannon built into the Tibesti Mountain range, Chad. SCP-4097 is similar in construction and design to the German Big Bertha howitzer with the significant differentiating attribute between the two being SCP-4097's size. SCP-4097 is approximately 42 m long, 27 m wide and 67 m in height. SCP-4097 has barrel size of 14 m and is capable of accurately hitting targets up to 8000 km away with little strain on SCP-4097. How SCP-4097 is currently able to attain this sufficient firing distance while using seemingly standard firing methods is presently unknown. SCP-4097 has no defining markings on itself or any of its components except for on the underside of SCP-4097's barrel which reads "Tunisie-Sahara catégorie 14000 mm obusier 'Le baroud d'honneur'"1. When SCP-4097 is fired, SCP-4097 is capable of creating a sound of approximately 172 decibels at 30 m of distance.

SCP-4097's ammunition is kept within a storage facility connected through a complex series of levels and tunnels scattered throughout the Tibesti Mountain range. The entire complex spans approximately 14 km in total distance and includes:

  • 12 magazines
  • 3 barracks
  • 5 staff rooms
  • 2 office levels
  • 1 war room
  • 1 armory
  • 1 cargo bay
  • 1 med-bay
  • 1 vehicle bay
  • 4 security rooms
  • 1 interrogation room
  • 2 entrance/exits

Each magazine in the complex, which has been integrated into Provisional Site-176, contains a different form of shell designed to fire from SCP-4097, designated SCP-4097-A/1 though SCP-4097-L/12. All SCP-4097 ammunition entities are different in shape, size, weight and anomalous effect (See Addendum-A). Currently, all magazines in the complex are open and under examination except for Magazine-12, which is prohibited from being opened until a way of containing SCP-4097-L/12 effects has been discovered (See Addendum-B).

The complex itself, and by extent SCP-4097, was presumed to be built in the mid-late 1950's by French military forces before the decolonization of the region in 1960. Multiple French flags and French Army Insignia's are found throughout the complex, primarily in staff rooms and barracks. Signs of heavy fighting and explosive damage to the complex are prominent around the southernmost entrance. Several French EBR-75 FL-11 armored cars were discovered in the complex's vehicle bay, all showing signs of substantial damage. One Soviet PT-76 light amphibious tank was found critically damaged outside of the southernmost entrance to the complex.

During the initial recovery of SCP-4097 and its associated complex, large sums of skeletal corpses dressed in the uniforms of the French 1st Artillery Regiment, French Direction du renseignement militaire (DRM)2and Soviet 6th Guards Tank Army was recovered. Despite evidence leading to French construction of SCP-4097 and the following assault by Soviet forces, both French and Russian armed forces retain no knowledge of SCP-4097 or any conflict that may have taken place there.3

Addendum-A:

Item Designation/Magazine# Size Weight Anomalous Affect
SCP-4097-A/1 14 m Diameter, 6 m in height. ~43300 kg When fired from SCP-4097, SCP-4097-A/1 will, upon detonation, create an electrical discharge of approximately 12'000 volts of fatal electricity into a given area as well as causing an explosion with a yield of approximately 0.25 kiloton. SCP-4097-A/1 is believed to be capable of producing an electrical discharge via a 24 cm x 17.5 cm x 21 cm sized device in the casing of SCP-4097-A/1. The device is currently under active examination.
SCP-4097-B/2 14 m Diameter, 6 m in height. ~44300 kg When fired from SCP-4097, SCP-4097-B/2 will, upon detonation, create an area of extremely high pressure in an approximate 2 km range. Inside this area, atmospheric pressure will rise until it reaches the point where the human nervous system would be irreversibly damaged. SCP-4097-B/2 is incapable of affecting the surrounding atmosphere, although pressure headaches and nosebleeds become increasingly common directly outside of SCP-4097-B/2's area. SCP-4097-B/2's effect lasts approximately 2 minutes before the pressure in the area slowly begins to return to normal. SCP-4097-B/2 creates no explosion upon detonation and is fitted with a device with a similar design to an air conditioning unit. It is currently unknown how this device operates.
SCP-4097-C/3 13.2 m Diameter, 7.2 m in height. ~41900 kg When fired from SCP-4097, SCP-4097-C/3 will, upon detonation, explode with the force of a 2 kiloton bomb and release a shockwave capable of causing the human lungs to rupture among other extreme internal damage in a 15 km radius. The shockwave of SCP-4097-C/3 is capable of being fatal even when ensconced in concrete bunkers and has proven to be deadly to all living beings inside of its radius. It is currently unknown how SCP-4097-C/3 is capable of producing an explosion of this magnitude with its size and explosive capabilities.
SCP-4097-D/4 13.6 m Diameter, 7.4 m in height. ~44100 kg When fired from SCP-4097, SCP-4097-D/4 will, upon detonation, release a dust-like material that retains the intelligence of a hive-mind insect and will actively attempt to hunt down and enter the human respiratory system via the oral and nasal cavities of the victim. A collection of the particles emitted at detonation kept within the casing of SCP-4097-D/4 have shown that they are mainly constructed of grounded down granite with significant residue samples from [REDACTED]. It is currently unknown how the French government was able to attain [REDACTED] in the 1950's.
SCP-4097-E/5 13.3 m Diameter, 7 m in height. ~44500 kg When fired from SCP-4097, SCP-4097-E/5 will, upon detonation, Create an area of mass molecular destabilization resulting in the complete molecular deconstruction of any structure or creature in its area of effect of ~4 km. Diagnostics performed on SCP-4097-E/5 instances have revealed a miniature device constructed into the warhead resulting in SCP-4097-E/5 temporarily constructing an Oswald-Class matter deconstruction event where it detonates. The device itself has been named an O'Neal Deconstruction Device (ODD) and uses the projection of electron particles to destabilize atoms, causing them to essentially propel their electrons out, creating a chain reaction of extreme structural deconstruction at an atomic level. The research behind the functions and dangers of SCP-4097-E/5 is currently ongoing.
SCP-4097-F/6 14 m Diameter, 6 m in height. ~43000 kg When fired from SCP-4097, SCP-4097-F/6 will, upon detonation, cause extreme structural failure in all constructs produced with some form of metal or metallic substance. SCP-4097-F/6, unlike other SCP-4097 ammunition entities, serves no threat to the biological human or any other living creatures and is instead suspected to be designed with used with defensive positions or/and armored units in mind. SCP-4097-F/6 has an effective range of approximately 34 km and is responsible for the destruction of Test Site-4097 "Little 19". Diagnostics performed on SCP-4097-F/6 entities are to be performed using tools constructed out of industrial diamond4 to counteract SCP-4097-F/6's anomalous properties.
SCP-4097-G/7 N/A N/A It is currently unknown as to the direct effects of SCP-4097-G/7 as, following firing from SCP-4097, its antimemetic properties affect anyone caught in its effective radius of approximately 237 km5. SCP-4097-G/7 will also affect individuals viewing the detonation, whether directly or indirectly. They will forget about both the detonation of SCP-4097-G/7 and all of its defining features. It is currently unknown as to the force of which SCP-4097-G/7 detonates with or the damage it delivers to its intended target. The amount of SCP-4097-G/7 entities fired, their target, or if more than 1 entity has ever been fired while in Foundation control is currently unknown.
SCP-4097-H/8 N/A N/A Upon recovery of SCP-4097, it was discovered that all SCP-4097-H/8 entities had detonated in their magazines. Currently, Magazine-8 has been entirely consumed by a fire started via SCP-4097-H/8. It is believed that SCP-4097-H/8 was an incendiary weapon before its detonation as the fires it created appear to burn without a consistent fuel source. As of now, no form of FPE6 has proven effective against SCP-4097-H/8's fires.
SCP-4097-I/9 14 m Diameter, 4 m in height. ~40800 kg When fired from SCP-4097, SCP-4097-I/9 will, upon detonation, release an electromagnetic pulse capable of disabling all electronic devices within a 12 km radius. SCP-4097-I/9 has no explosive potential and can be recovered, repaired and reused. SCP-4097-I/9 appears to use a combination of currently unidentified electronic devices within its casing to release its pulse. Research into SCP-4097-I/9's abilities are currently ongoing.
SCP-4097-J/10 14 m Diameter, 22 m in height. 0 kg When fired from SCP-4097, SCP-4097-J/10 will activate a set of thrusters residing near the rear of the shell, allowing it to remain effective even with its passive effect. Following initial firing, SCP-4097-J/10 will, instead of colliding with the target area before detonation or air detonating, SCP-4097-J/10 will 'fly' to about 2 km above its target area before detonating. Upon detonation, SCP-4097-J/10 will begin to form a strong gravitational pull towards itself, causing objects and subjects in the area to begin floating uncontrollably towards it in a radius of about 2.5 km. After approximately 2 1/2 hours, SCP-4097-J/10's will explode with an explosive yield of approximately 0.25 kilotons and its effects will dissipate, causing the remains of any subjects or objects inside of the area to fall to the ground. Unlike other SCP-4097 ammunition entities, SCP-4097-J/10 features a passive effect when not fired, as SCP-4097-J/10 are seemingly unaffected by the forces of gravity and are held in their magazine via ropes and other constraints. A way of stabilizing SCP-4097-J/10 during diagnostics is currently in development.
SCP-4097-K/11 14 m Diameter, 6 m in height. ~43700 kg When fired from SCP-4097, SCP-4097-K/11 will, upon detonation, release a toxin similar in build to chlorine gas into the air. This gas will proceed to settle onto the ground and remain there. It appears that SCP-4097-K/11 acts as a form of thermal paste, and will actively consume thermal radiation in the area, resulting in nearby environmental instability. Diagnostics performed on SCP-4097-K/11 has yet to discover the source of the paste or how it is capable of releasing the paste without exploding.
