Item #: SCP-3706
Object Class: Safe
Special Containment Procedures: Locations with high probabilities of producing or uncovering SCP-3706 instances are to be monitored closely by implanted Foundation archaeologists and paleontologists. Should an SCP-3706 instance be uncovered, non-Foundation personnel present on site are to be administered class A amnestics, and disinformation regarding recent discoveries disseminated in the event of further inquiries.
SCP-3706 instances are to be moved to secure engineering Sites 212A or B depending on size and condition. Functional instances are to be moved to 212A for potential reactivation and reverse engineering. Non-functional instances are to be moved to 212B for proper thaumaturgic disposal, and destruction.
All tests, operations, and information requests for SCP-3706-380 are subject to Level 5 approval. Key personnel who have knowledge of SCP-3706-380 have been granted restricted level 5 clearance to necessary documents pertaining to OPERATION HIGH TIDE. Abuse of this clearance is grounds for termination.
Site 212A
Site 212A is a facility located on the Dunnethead Peninsula southeast of the Orkney islands encompassing an area of 12 km2. Three 500 m2 vehicle storage warehouses are positioned along the coastline, with open access to coastal waters for functional testing of reactivated SCP-3706 instances. A permanent staff of 1000+ individuals, including MTF-Sigma 32 ("Recovery Wizards") are housed on site at all times.
The area directly encompassing 212A has been designated as a No-Fly zone by the government of the UK. This status extends into the surrounding oceanic waters in a 2 km radius.
Site 212B
Site 212B is a facility located on the Western coast of Hoy Island. Site 212B consists of a 50 m x 20 m compound capable of housing and decommissioning non-functional thaumaturgic items. Site 212B has a permanent security staff of 15, and 5 thaumaturgic demolition experts.
Description: SCP-3706 are a large number of recovered and potential undiscovered vehicles with unique properties, several universal common factors, and varying functional attributes. Each SCP-3706 instance is capable of traversing aquatic environments, either as a submersible, or sea floor based all-terrain vehicle. Each vehicle resembles known species of ocean fauna, though significant deviations from these animal species have been observed in many recovered instances, as is described in Table T-3706-01. Individual vehicles are primarily composed of organo-metallic polymers, with the oldest variants having been carved from stone. Vehicles that do not use appendage based locomotion employ a jet propulsion mechanism involving the intake and rapid expulsion of ocean water through adjustable vents.
SCP-3706 instances are diverse in both appearance and specific function, ranging from automated collection vehicles less than 3 m in length (designed to collect food, minerals, and other materials) to large-scale assault vessels more than 200 m in length. Each SCP-3706 instance is powered via a spatial distortion contained within a crystalline chamber composed of corundum, which produces high energy material bearing marked similarity to that found in SCP-3703. The size of both the crystal and the distortion appears to vary based on the size of the vehicle; however, the crystals of all recovered non-functional instances are either shattered or missing.
When in an active state, all SCP-3706 instances emit a dull "humming" noise. Active SCP-3706 instances possess carved channels where luminescence will "flow" across their exterior surfaces, forming patterns, artistic depictions of the vehicle's history, and Proto-Nordic runic script containing instructions on how to properly operate and maintain each vehicle. Additionally, manually piloted SCP-3706 instances tend to have detailed markings, carved by the former operator onto their vehicles, in the form of three-toed hoofprints. These appear to serve a statistical role, similar to the manner in which pilots during World Wars 1 and 2 would track enemy kills by painting flags onto their vehicles.
Table T-3706-01
The following table contains selected entries describing the various instances of SCP-3706. Vehicles are assigned designations based on their type and relative functionality compared to other SCP-3706 instances rather than by order in which they were discovered. Prior documentation included designations based on order of discovery, these designations have been changed database-wide in order to avoid confusion.

Description

SCP-3706-01
Self-Propelled Automated Collection
Collection of vehicles recovered off the coast of the Peloponnese Peninsula. Vehicles ranged in size from 0.3 to 2 meters in width, 0.1 to 1.5 meters in height, and resembled varying members of the infraorder Brachyura.1 Notable common features included replacement of the claws with four slotted limbs possessing varying tools. 3 instances possessed grafted human hands. All instances were functional at time of recovery.

SCP-3706-09
Self Propelled Automated Collection
Numerous vehicles recovered in a large number of rivers in the United Kingdom and continental Europe, as well as portions of the North Atlantic, North and Baltic Seas. Vehicles range in size from 0.5 m to 5 m in length, and width. Due to their size, the majority of recovered instances resemble the Atlantic Bluefin Tuna, with notable differences in the mouth, which lacks any teeth, and a large cavity at the very tip of the tail, often possessing luminescent markings across the exterior. All instances make a constant humming described as "eerie."

SCP-3706-15
Personnel Transport
Vehicle recovered off the coast of Iceland. It measures approximately 8 meters in length, 6 in width, and 5 in height. Vehicle resembles the Dorado/Mahi-Mahi, with notable modifications, including large hollow chambers with sufficient seating for 15 individuals, four large yellow orbs2 arranged equidistantly, with two on either side of the vehicle, and remnants of thaumaturgic power nodes leading to what may have once been weaponry. Inscriptions on the interior of the vehicle have been translated and interpreted to "Place your hand on the triangle, the big green one, and press down. If she doesn't start, bang the fins several times. She's old and cranky."

SCP-3706-230
Personal Combat
Vehicle recovered off the coast of the Canary Islands. Approximately 2.5 m in length, 1.4 m in width, and 1 m in height. Resembles Carcharhinus leucas3 with notable modifications to the "nose" of the vehicle which broaden it into a sickle moon shape, possessing four carved grooves with corundum coating the interior. The vehicles' dorsal fins possess inscribed markings in the shape of three-toed hoof-prints, with a total of 60 spread across the vehicle. Proto-Nordic runes are inscribed along several parts of the vehicle, with notable differences in the style of carvings. For the sake of brevity, these have been recorded in the section below.

Translation T-3706-01:
The following contains an interpretation of the inscribed runes on SCP-3706-230.

"Hey hotshot, congrats on getting your certification. This beauty is named BJÖRT. She's good, but to earn her trust, you're going to have to hit at least five humans in the water, and make sure you get their blood in her mouth." ~Snorre
"Greetings new aquaneer, please disregard the above message. This aeronautic does not require human blood sacrifices to operate. We are not savage primitives." ~Magister Rolf
"No seriously, don't listen to the Magisters. They like to see new guys be unable to operate their machines on the first go. It's just five humans. C'mon, you know they aren't doing anything but tossing spears at each other." ~Snorre
"Please ignore all markings from Aquaneer Snorre. He has been reprimanded for encouraging prejudiced uncivil behavior towards other thinking beings." ~Magister Rolf
"Yeah, well let's see you reprimand me when I take this thing and fly off, you vagr níðingr." ~Snorre

A single set of skeletal4 remains were recovered 1.5 m from the vehicle on the ocean floor. Skeletal remains matched those recovered from SCP-3047.

OPERATION HIGH TIDE

Designated Object: SCP-3706-380
Asset Status: Active.
Recommendations: Use not advised due to destructive potential. Priority should be given to search and acquisition attempts of all similar vehicles.

Description: SCP-3706-380 is a vehicle, 200 meters in length, excluding all tentacles, 125 meters in width and 75 meters in height. The superstructure resembles the Australian giant cuttlefish, Sepia apama, with notable major modifications, including six 50 m "arms" capable of supporting the vehicle in traversing terrestrial environments, and two tentacles capable of more directed, dexterous movements. Large channels, which form a circuit of constant luminescent blue, green, and yellow light, cover the exterior hull, forming intricate patterns of symbolic and spiritual significance.5 Four large equidistant yellow orbs are positioned at the anterior end of the vehicle, resembling eyes.
Interior spaces are broken down into 16 individual decks, with various facilities for long-term residence. SCP-3706-380 is capable of housing a crew of 325 individuals, and can carry up to 800 personnel for short periods.
SCP-3706-380 is equipped with 14 major weapon emplacements, including a high yield thaumaturgic beam weapon in place of a vessel's mouth, and a number of smaller defensive emplacements. Major emplacements consist of rotating oblong ovals with grooves carved at equidistant intervals on the minor axis of the top face. During the firing of major emplacements, carved channels within the vicinity of the weaponry will change color to a distinct reddish tone.

History: SCP-3706-380 was discovered on June 5th, 1935, in the North Sound 3 km off the coast of Westray, Orkney. At the time, the vessel was stuck in the ocean bed, and had been inundated by the surrounding oceanic waters due to an open hatch on the dorsal face. 257 skeletal remains consistent with those found near SCP-3706-230 were recovered, and transported to a small outpost at what is now Site-A, where it was determined the remains were not of human origin. Later excavation of the surrounding ocean bed uncovered traces that SCP-3706-380 had been accompanied by additional vehicles; however, no other intact vehicles were recovered.6
Initially, an attempt was made to lift SCP-3706-380 from the ocean floor under the guise of recovering a valuable shipwreck. The outbreak of Occult War VII indefinitely delayed these plans, and SCP-3706-380 remained untouched for the next 15 years. Foundation paleontologists began to uncover significant numbers of other, similar artifacts, at which time the subject was revisited and a recovery operation was planned and executed. Full recovery of the vessel occurred on June 7th, 1951, and SCP-3706-380 was temporarily stored at a set of makeshift drydocks where Site A now stands.
Full inspection of the vessel determined that it had taken significant damage from exposure to salt water for approximately 50 years. Unlike other wrecks of similar age, there was a distinct lack of significant ocean flora inhabiting the vessel. Initial assessments indicated the vessel would be impossible to restore, and SCP-3706-380 was slated for disassembly and decommissioning. This mandate was counteracted by special interests from the O5 council, after an engineer stumbled upon an active power source while cataloging the interior in preparation for demolition. A special project was approved to repair and restore functionality to the vehicle, and began in earnest on August 5th, 1956, with the construction of Site A.
As knowledge of the vehicle and its functionalities was minimal, progress was initially slow; however, with the discovery of additional SCP-3706 instances, and the slow reverse engineering of said vehicles, full repairs were completed by March 18th, 1977. Additional SCP-3706 instances were moved to the site for functional studies, and a sister site was constructed for demolition of non-functional vehicles, Site B.
Functional restoration began on the same date, and by August 23rd, 1985, a monumental breakthrough in the translation of the Proto-Nordic runes allowed Foundation personnel to translate markings on all recovered instances of SCP-3706 by that date. Proper interpretation took longer, due to the structure and grammar of the language, with linguistic mapping and a full understanding being attained on September 5th, 1990.
On December 13th, 1995, Foundation personnel restored functionality to advanced onboard life support systems, leading to the discovery that the vehicle had previously been partially inundated with salt water. This function was disabled. Navigational systems were restored 2 years later and on October 15th, 2006 full engine functions were restored.
A skeleton crew of 57 individuals was brought to Site A and underwent the necessary linguistic and functional training to operate SCP-3706-380. The maiden voyage of SCP-3706-380 was continuously delayed, due to more pressing projects in other sectors; however, following the events of Incident I-3700-032 the vessel's maiden voyage was scheduled for March 30th, 2017. During SCP-3706-380's maiden voyage Incident I-3706-01 occurred as described below.

Incident I-3706-01: On March 30th, 2017, SCP-3706-380 was launched into Pentland Firth for a shakedown run. Six additional personnel were aboard, including two O5 aides and four engineers overseeing the restoration efforts. The vessel proceeded into open waters, where it remained along the surface and accelerated to a speed of 25 knots. A predetermined course was followed, which included two passes near the village of Harrow.
Prior to the voyage, engineers were forced to reboot the engine systems due to a software glitch, unknowingly restoring functionality to the weapons due to a previously undetected blockage in the power channels around the spatial distortion being removed. As such, on the second pass by the village of Harrow, Commander Sarandine Lee, who was piloting the vehicle in conjunction with several other trained personnel, pressed her right palm on a previously unactivated imprint. At this time, a number of alarms engaged, and the uppermost arm of the vehicle was lifted out of the water.
Individuals within the vessel proper, and on accompanying security craft, described a mechanical roar emanating from within the vehicle. A "column of light" emanated from a previously unobserved opening, near the point at which the motile limbs are attached. It made impact with the village of Harrow less than a kilometer away.
Forensic recreation indicates the hamlet, and all structures within a 300 m radius, were instantly vaporized, leaving a 6 m deep crater in its place. Security protocols were immediately implemented, and all potential witnesses administered necessary amnestics. Inquiring citizens were informed that the explosion, and subsequent incineration of the village, was due to the accidental detonation of military ordinance being loaded onto a ferry for transport to a disposal facility in the Orkneys. Further voyages, and testing have been postponed in order to ascertain further offensive capabilities. The estimated death toll, at this time, is 56 adults, and 5 children. Full recompensation has been offered to any surviving family members.
Following the incident, training regimens for individuals selected to crew SCP-3706-380 have been sufficiently altered in order to avoid future incidents with the vehicle's weaponry. Large warning labels have been attached to all terminals, imprints, and mechanical devices known to activate or control emplacements, major or minor.

Recovered documents and materials: SCP-3706-380's initial recovery also salvaged a number of artifacts, including numerous thaumaturgic artifacts7 as well as personal belongings as indicated below:

Combs made from sea shell fragments, and urchins.
Beds and cloths made from kelps and other seaweeds.
Nets, spears, and other equipment with traces of large numbers of varying fish species.
Decorative personal items, such as candles in containers made of varying ocean flora and fauna with notable deviations from normal species.
Moving paintings and photos depicting large-scale environments which do not match with any known geographical features.
5 humerus bones, 3 meters in length. 1 pair of hands, with elongated phalanges ending in hardened, sharp, and curved segments of thick ossification, 1.7 m in width, and digits that are each 1m in length.

Two compartments were discovered in a large set of personal quarters near the "bridge" of the vessel. Each compartment contained a bound book, believed to be, after careful examination, ship's logs, with paper composed of seaweed. Upon recovery, it was determined, due to the presence of excess water, that one of the sealed compartments had been compromised. Water damage has rendered the book kept in this compartment unreadable. The other book possesses a single entry in Proto-Nordic runes. This entry has been translated, and interpreted as given below:

Undecipherable handwriting believed to be a date.
They're everywhere. We're abandoned.
Abandoned. Helga… my love. I sent the message. I sent it so many times. None answer.
Cursed man of Guð-Bani8… glory against the demon of the deep in war… only death.
Exile.
Starving.
Trapped by the demons in the bed.
No way out.
No way out.
No.
Way.
Out.

Footnotes
1. Crabs.
2. The material with which the orbs were made appears to be different, and less worn than other portions of the vehicle, and a number of fresher carvings around the orbs form a large circle which would be visible if the sides of the vehicle were to unfold.
3. Bull Sharks
4. Observed remains appear to be anatomically similar to baseline humans, with the exception of several prominent features, including atypical body cavities around the neck and shoulders, in some cases containing what appears to be a second layer of desiccated preserved skin, nodules along the bones of the arms and legs and preserved cartillage for the support of fins. These are notably similar to remains observed in SCP-3703-1 instances.
5. Including depictions and motifs of conflicts in which it may have participated.
6. Extensive excavations from March of 2000 to July of 2008 recovered a large number of scattered skeletal remains. These included remains consistent with those found aboard the vessel. Additional remains, inconsistent with those found aboard the vehicle, included disproportionately large sets of remains, several of which could not be identified with any known species.
7. Notably, projectile weaponry using large feather-like projectiles with sharpened edges, and elemental energy.
8. Old Norse for Godslayer and believed to be a reference to SCP-████.
