Item #: SCP-5XXX
Object Class: Keter
Special Containment Procedures: Item is currently unable to be contained due to the sheer scale of the object, however items appears to be self contained as it is missing the means of activation and is currently buried underground. Guards are to patrol the above ground area dressed as forest wardens, and to deter anyone entering the area above SCP5X by claiming that it contains a rare and highly traversable floral and fungal disease that migrates on the bottom of shoes and tires. Anyone found in violation of this will be taken aside and will go through a fictionalised and theatrical version of a decontamination cleaning. Anyone that finds an exposed part of SCP5X or anything anomalous will be given a class B amnesic and have false memories implanted that they found nothing.
Description: SCP5X is an armoured artillery vehicle that appears to be seven square miles in size. It seems to be armed with a series of firearms the smallest of which seems to be a 70mm Automated machinegun, and the largest of which seems to be a cannon with a singular round that has the diameter that has been estimated at about a mile. This great gun runs on tank-like treads that are set up more akin to the enormous walking excavators than a traditional tank, however with its situation it is currently buried under thousands of tons of dirt and snaking tree roots so it is uncertain if it could move. The technology of the gun early to mid 1900s, with the weapon itself having many anomalous properties that have allowed it to even be physically possible let alone survive and even able to be used without anyone maintaining the equipment or technology. On one side, printed in large letters, are the words “The Last Dreadnought” over standard issue military green metal paint. The paint is one of the few things that is showing damage, which concludes that the paint is non-anomalous. On one of the gantry ways there seems to be a punch card computer system terminal with a typewriter style keyboard and speaker connected to an oscilloscope style screen. While there would be enough room inside to fit a considerable size city, there seems to be no way to get inside the artillery vehicle, and the only place that it can interacted with are those places where there are the terminals. Several of them dot around the outside. There is also one on top, next to a table and a map that can be used to garner exact co-ordinates from most places around the world, however the measuring arms were damaged when the roof collapsed.
The vehicle was found buried under the southern coast of [Redacted] after locals attempted to build a better sewage system, and mistook one of the gun barrels for large underground pipeworks of unusual design. Though it was seemingly built using parascience of the early to mid 1900s, the weapon did not seem to be designed to be used again German occupied Europe for either world war. Research has showed that, though technically mobile, its current position and direction of fire does not seem to aim the main weapon at anything that would be considered vital during either European campaign.
Researchers speculate that this means that the target it was intended for was a yet as unknown target. Speculation is ongoing with researchers calculating what could be possibly along its current trajectory. It has also been speculated that many of the resource shortages during the world wars were actually in, some small part, due to the possible construction of such a large weapon.
Given the scale of the weapon, it has been calculated that if it were to fire it could cause considerable damage to the surrounding country, possibly disturbing or even cracking the tectonic plate it sits upon and throwing most of mainland Europe into turmoil with potential extreme weather devastation. Even simply moving the item would cause irreparable damage to the host country. It is unsure how much damage would be caused by the main weapons upon an indicated target, however it is estimated that it could be measured in megatons.
It has been speculated that the weapon had to have been constructed underground, or else there would have been no means to hide such a large construction project, with local trees, wildlife and natural entropy having collapsed the temporary structure around it to allow the machine to become buried. Tree roots have worked their way through the brick roof of the underground bunker and have tangled themselves up into some of the workings and firing mechanisms so certain technologies aboard SCP5X might be unable to function, had the foundation the means of actually activating them. SCP5X seems to have an automated system that has control of the firing protocols. While SCPX’s automated systems are unable to pass the Turing test, and thus is not sentient as we understand some modern computer intelligences to be, researchers were still able to converse with the targeting and tactical assistance system, or TTAS. It would seem that the automated systems also contain automated defences, and as such interfering, inspecting or attempting to enter SCPX should be done by D-class personnel.
While it has been difficult to obtain internal images of SCPX, using ultrasound radar, thermal imaging and T-ray scanning experimentation has allowed foundation researchers to speculate there seems to be a factory like structure inside with something at least partially organic moving around inside. The 05 council are currently considering means of infiltrating the machine without risking considerable foundation lives.
SCP5XXX-B is a punch card, approximately 25 inches long and 10 inches wide with a series of holes cut out of an unknown, card like, material. It is a white card with a blue stripe that sits diagonally across. White writing can be found on the blue stipe stating “Personnel information - 1”. It is to be read by the custom hardware on SCP5XXX, however the foundation has been yet to recreate a punch code machine or cypher that would allow them to read the information.
Addendum:
SCP5X interview log
Researcher Dr X conducted several psudo-interviews with this TTAS system in order to garner more information. Before each response there seemed to be a pause, then a series of mechanical noises as if it had been fed a punch card of some kind. In terms of larger requests the sound of punch cards can be heard across the entire scope of the machine.

TTAS: THIS IS THE ONBOARD TARGETING COMPUTATIONAL ENGINE OF THE LAST DREADNOUGHT, THE TARGETING AND TACTICAL ASSISTANCE SYSTEM. TO WHOM IS THIS UNIT TO RECEIVE INSTRUCTIONS FROM?
USER 19: I am Dr . Are you an intelligent entity?
TTAS: QUANTIFY INTELLIGENT.
USER 19: Are you sentient?
TTAS: NEGATIVE.
USER 19: You seem sentient.
TTAS: NEGATIVE. TTAS WAS PROGRAMMED TO REPLY IN A MANNER EASILY UNDERSTANDABLE BY LAYMEN TO FACILITATE EASE OF USE. SENTIENCE WOULD HINDER TARGETING. PLEASE ENTER TARGET.
USER 19: We do not have a target for you at this time, this is merely a maintenance check.
TTAS: UNDERSTOOD. PLEASE STATE YOUR REQUESTS.
USER 19: Are you willing to answer questions at this time?
TTAS: AFFIRMATIVE. PLEASE BE PATIENT AS TAPES AND PUNCH CARDS MAY NEED TO BE CHANGED DEPENDING ON INFOMATIONAL REQUESTS.
USER 19: Very well. Please explain what you are.
TTAS: THIS IS THE ONBOARD TARGETING COMPUTATIONAL ENGINE OF THE LAST DREADNOUGHT, THE TARGETING AND TACTICAL ASSISTANCE SYSTEM.
USER 19: Correction: I meant the entire apparatus.
TTAS: THIS CONSTRUCT IS THE LAST DREADNOUGHT; CONSTRUCTED BY THE FINEST MINDS IN ORDER TO FEND OFF A THREAT TOO POWERFUL FOR CONVENTIONAL FORCES.
USER 19: Please identify threat.
TTAS: ERROR. UNABLE TO COMPLY.
USER 19: Explain.
TTAS: TARGETING INFOMATION NOT FOUND. PLEASE ENTER TARGET INFOMATION.
USER 19: If we give you a target, will you immediately fire upon them?
TTAS: NEGATIVE; ONLY IF THERE IS IMMEDIATE THREAT WILL THIS UNIT FIRE WITHOUT INSTRUCTION.
USER 19: Define immediate threat.
TTAS: UNACCEPTABLE LOSS OF HUMAN LIFE, OR DESTRUCTION OF THE LAST DREADNOUGHT. THIS CONSTRUCT WAS CRAFTED TO SAVE HUMANITY.
USER 19: I am going to log off. We shall continue later.
TTAS: UNDERSTOOD DR . THE LAST DREADNOUGHT SHALL REMAIN VIGILANT.
Session was terminated. Information was sent to the higher ups in order for a planned exploration or experimentation schedule to be developed.
Session 2
05 council examined the results of the last interview and gave authorisation for theoretical experimentation. The next "conversation" with the TTAS was done upon the targeting gantry with the large ten meter by ten meter map of the earth. Given the estimated creation date of the SCP, it was decided to feed it an extant threat to see what sort of threat it was designed to deal with.
SESSION 17-05-2020
TTAS: PLEASE ENTER TARGET DATA…
USER 19: No target data yet. Is there a way for you to use standard punctuation for the means of communication.
TTAS: ONE MOMENT PLEASE…………………….Preferences set. This Unit hopes that this is more agreeable to the user.
USER 19: It is. Please prepare for a hypothetical targeting situation.
TTAS: Is unit to move as if to prepare a firing solution or just to calculate requirements?
USER 19: You are capable of locomotion?
TTAS: Yes. Preparing locomotive force.
USER 19: CANCEL.
TTAS: Locomotion cancelled.
USER 19: DO NOT MOVE. Calculation is fine.
TTAS: Understood. Please enter theoretical targeting data.
USER 19: Are you able to fire upon Nazi Germany?
TTAS: Negative. Conventional arms are enough.
USER 19: But I what if we wished to destroy them?
TTAS: Negative. The Last Dreadnought was designed to face a foe that could not be stopped by conventional means, when all hope is lost.
USER 19: Identify foe.
TTAS: Data not found. Please enter target data.
USER 19: So you know what not to shoot at, but not what to shoot at?
TTAS: Correct. The targeting computational engine feeds data to the other systems, and the other systems calculate the military need of the situation. While Nazi Germany has a potent military, conventional and emergent technologies are more than enough to wage war on such a power. Recommend expanding alliance with the Americans and Soviet militaries.
USER 19: So you are able to provide tactical information as well?
TTAS: That is correct, however only to a limited extent. Please feel free to adapt these recommendations.
USER 19: How were you able to recommend such a stratagem to us?
TTAS: The Last Dreadnought was constructed and programmed by some of the finest minds of their fields. This included military strategy.
USER 19: Please give us a list of those that were involved. in your construction.
TTAS: One moment please…………….Punch card dispensed on Gantry A - 7 which contains all information.
USER 19: Can you not tell me who was involved in your construction?
TTAS: Please wait……………………………….This unit is sorry, however the Information has not been found. Records indicate that the punch card with that information on it was dispensed by USER 19 a few moments ago. please reinsert it into the dispenser on Gantry A - 7.
USER 19: Very well. Please re-enter standby mode. I am logging off now.
TTAS: Understood. This unit shall remain vigilant.
Session 2 ends with the collection of the punch card which has been designated SCP-5XXX-B. The Punch Card seems to be a proprietary data storage system with unique anomalous properties, and as such has not yet been returned to SCP-5XXX. Foundation personnel are currently studying it in the hopes of deciphering how large amounts of information can be stored upon a comparatively small and antiquated system and if that is an extension of the anomalous para-science used in the creation of SCP-5XXX.
Incident SCP-5XXX-ALPHA
During an examination of the system, a junior researcher was given permission to ask questions of the TTAS in order to gain a better understanding of the limits of its cognitive range. To this end a more senior researcher had given the go-ahead to give it some uncontained SCP targets.
SESSION 30-05-2020
TTAS: Please enter target information.
USER 20: Good afternoon TTAS; please prepare for a targeting exercise.
TTAS: Certainly USER 20. Please input hypothetical threat.
USER 20: Please target SCP 957.
TTAS: One moment please……………….Name not recognised. Please enter more target data.
USER: Cancel that request then. Prepare for new hypothetical.
TTAS: Of course. Please input target data.
USER 20: Please target SCP 1440 - The Old Man from Nowhere.
TTAS: Processing…Target acquired. Firing solution acquired. Firing this shot will endanger an unacceptable number of the lives in Aktobe, Kazakhstan. Also subject can be detained using conventional forces.
USER 20: Define "unacceptable".
TTAS: According to this unit's parameters killing all of Aktobe, Kazakhstan to eliminated one old man is not acceptable.
USER 20: Understood…Prepare for another firing solution.
TTAS: Understood.
USER 20: Please prepare a firing solution upon the Broken God.
TTAS: Negative…..Unable to comply. Firing solution impossible.
USER 20: Please elaborate.
TTAS: Unable to comply. Please enter alternative target.
USER 20: Fine. Fire upon the red spot of Jupiter then.
TTAS: Unable to comply - target too far away.
USER 20: Well how about you target the scarlet king? Think you can do that?
TTAS: Negative.
USER 20: What is the issue this time? Or can you not say again?
TTAS: Scarlet King not on this plane. Physical limitations of firearms means the shot would miss. Target data saved.
USER 20: Excuse me?
TTAS: Target: Scarlet King added to fire list. If a shot can be made, the Last Dreadnought will fire main battery.
USER 20: Firing order not given. Do not fire automatically.
TTAS: Unable to comply. Scarlet King considerable enough threat to warrant immediate danger to humanity. Presence upon this reality constitutes an emergency. Will fire main battery if targeting solution can be met.
USER 20: DO NOT FIRE MAIN BATTERY.
TTAS: Unable to comply. Threat is too great.
USER 20: ….
TTAS: The Price of Existence is Sacrifice; if at least some of humanity survives then that is the best outcome.
No more hypothetical firing solutions will be given to SCP 5XXX, for risk of accidentally having it fire. Junior Researcher [Redacted] has been reprimanded and remanded for interrogation due to possession of information above his clearance level. Researchers are looking into a possibility of components of SCP 5XXX having components or knowledge biased in favour of the Broken God, thus being unable to fire upon it.
Incident SCP-5XXX-BETA
During physical exploration of SCP-5XXX Dr [Redacted] was examining the damage done to the targeting table, while various Foundation personnel were investigating the weapons and ammo magazines that were upon it, thinking the device was non-hostile or inert. As a researcher opened a large magazine housing, a loud claxon blared throughout the underground cavern with messages appearing upon the computer screens.
WARNING! WARNING!
SECURITY BREACH IN AMMO DUMP 14-12 - DEPLOYING COUNTERMEASURES…….
+++*USER 19 HAS LOGGED ONTO TTAS SYSTEM
USER 19: Belay that, TTAS! Those are my people!
TTAS: Explain, Doctor. Countermeasures on standby.
USER 19: These people, they just wish to take a sample round to examine it.
TTAS: The Last Dreadnought cannot have its armament compliment disturbed on any level. The price of existence is preparedness. You will instruct your team to disembark.
USER 19: I am certain one round won’t constitute an issue. Please allow them to examine a round.
TTAS: This is not a negotiation. Deploying countermeasures.
At this point a potent aerosolised gas based weapon, identified as Mustard Gas, shot from the compartment and engulfed any agents and researchers that were near or around any open ammo magazine. Medical teams rushed to the various victims and they were evacuated to a nearby hospital with the cover story of having discovered a WW1 shell while metal detecting. As the foundation personnel were evacuated the magazine housing seemed to close themselves and the sound of thousands of guns cocking in unison filled the cavern. Heat cameras showed a increased heat from inside the Last Dreadnought. Though it is only theoretical the heat patterns indicate the starting of a manufactory system as if it is beginning to mass produce a metallic material.
All of the monitors had the same words blinking upon them.
THE LAST DREADNOUGHT SHALL NEVER SURRENDER.
HUMANITY SHALL BE SAVED.
