Item #: SCP-3704

Object Class: Thaumiel

Sub-Class: Eigenweapon

Special Containment Procedures: [Paragraphs explaining the procedures]

Description: SCP-3704 is the designation assigned to large scale submersible vehicles under the joint Foundation-Finnfolk command of Operation HIGH TIDE. Each vehicle has been designated SCP-3704-1 onward. At this time, SCP-3704-1 is complete; SCP-3704-2 through -4 are under construction.

SCP-3704-1 is a large, motile, deep sea vehicle resembling Coenobita brevimanus, a large species of "hermit crab". At its broadest point, it is approximately 5 kilometers in width; its highest point is approximately 3 kilometers terminating at a singular point along its shell. The vehicle portion of SCP-3704-1's interior consists of roughly 250 individual levels/decks, occupied by a diverse array of tall, narrow hallways and facilities necessary for maintaining the vehicles functions, and providing sufficient habitation for its crew for long periods of time.

During normal motion, all components of SCP-3704-1 remain both invisible and intangible, allowing it to remain hidden and unobstructed in oceanic areas possessing significantly shallower depths than its maximal height. Motion is the proximal method by which this function is activated; however, it can also be switched on and off at will by operation crews, allowing entry into and exit from the vehicle. SCP-3704-1 can be further subdivided into two sections, designated SCP-3704-1-A and SCP-3704-1-B, based on function.


SCP-3704-1-A designates the crab-like portion of the vehicle, and is responsible for locomotion along the sea floor. The hull is made of various metallic alloys1 A large numbers of carved runes, depicting various images of movement and utilization the vehicle's offensive capabilities, encapsulate the carapace. Varying segments of SCP-3704-1-A have been painted and adorned with various colors, including pinks, greens, yellows, and blues forming the visage of a four eyed human woman. Additional structural features of SCP-3704-1-A include:

  • 130 weapon emplacements along the dorsal ridge.
  • Direct beam emplacements on the eye stalks, used for multi-direction energy channeling and deep sea lighting.
  • Rapid electrostactic discharge devices along the interior of each claw.
  • A single large bore weapon attached along bottom of the vehicle's hull.
  • Carrier bays allowing deployment of smaller submersible vessels.
  • Large grooved alcoves at staggered positions along the hull, emit blue light when properly powered, and repel all projectiles regardless of composition.

Attached to the tail of SCP-3704-1-A is a green-blue corundum structure resembling a spiked, symmetric gastropod shell. When not under the effects of SCP-3704-1's intangibility systems, SCP-3704-1-B refracts all light entering its immediate vicinity, creating a localized aurora due to intricate murals carved onto the exterior of the shell. These auroras depict various events in the history of the Finnfolk.2

SCP-3704-1-B's interior does not align with the dimensions of the exterior crystal structure. It contains a gradually sloping cylindrical space (60 kilometers in diameter and length) connected to SCP-3704-1-A by sliding lead-lined doors. An image of this space has been attached to this document in order to aide in visualizing the following description.

The interior of the cylinder is composed of 3 smaller nested cylinders similar to designs for an O'Neil Cylinder3, with smoother, sloped edges. Each nested cylinder is described below:

  • Thick outer shell composed of topsoil, fresh and salt water environments. Interior surface consists primarily of coastal and lake shoreline and aquatic terrains. Disparate populations of nomadic finnfolk occupying this shell were able to avoid most of the consequences of Incident I-3704-01. 5 km of hollow atmosphere exist between the outer cylinder and the middle one.
  • The middle cylinder is 3 km thick on all sides, and composed of largely sandy limestone deposits. Its exterior surface is coated in green-blue corundum, and emits auroras in day night cycles. The interior surface is separated from the inner shell by 2 km of oceanic salt water. A large number of agrarian complexes exist in this space, but appear to be insufficient to fully support the population of the inner cylinder.
  • The inner cylinder consists of topsoil and bedrock layers, 3km thick. Like the middle shell, the inner shell's exterior surface is coated in corundum. The interior surface contains a large scale urban environment capable of housing 8-10 million Finnfolk. Further information on architecture, technological presence, and an assortment of street maps have been compiled into Document 3704-1-16. A palace complex, emulating greco-roman architecture, exists at the epicenter of a large transport network consisting of current driven canals which span the entirety of the inner surface.
  • A large network of crystalline tubes extends from the surface of the inner shell to the center of the space. All tubes intersect at a diamond encased SCP-3703 instance which serves as a power source for all functions of SCP-3704-1, and a source of light in day/night cycles for the inner shell surface.

Large columns of glass enclose dual lane, current driven water highways that are attached to, and permeate each subsequent cylinder. This allows for free movement between the different layers. Highway entrance and exit points in between the outer and middle shell are submerged in surrounding bodies of water.

Each cylinder rotates, generating sufficient centrifugal force to simulate gravity.4

Additional Schematic Information

Design schematics and historic documentation indicate that SCP-3704-1 was originally built for militaristic purposes, but has since undergone extensive modifications. Modifications are numerous, and varied, and will be covered in full in Document 3704-1-17. A few of the more notable modifications are presented below:

  • Improvised desalination plants at 8 points along the vehicles exterior, 4 along SCP-3704-1-A and 4 along SCP-3704-1-B.
  • Expansion of SCP-3704-1-B well beyond its original size.
  • Incorporation of net deployment mechanisms for corralling and capturing schools of fish.
  • 1300 smaller autonomous and non-autonomous vehicles resembling ocean fauna. Believed to be identical in function to SCP-████. Holding bays within both sections of SCP-3704-1 are capable of inundating up to 15400 vehicles of varying size.5 Reasoning behind the absence of the majority of these vehicles is unknown.(See Reactivation Log).

Initial Discovery log:

The following transcript depicts the initial approach and discovery of SCP-3704-1.


Discovery Log SCP-3704-D

Date: ██/██/████

Discovery Team: Delta-7 Recons 1, 2 and 3.

Vehicles: Mark 4 advanced submersibles.

Field Leader: Silus Smith

Foreword: SCP-3704-1 was discovered following the events of Incident I-3700-032. 3 submersibles were deployed to identify a previously undetected metallic object on the seafloor. Visibility in the post incident aftermath was notably poor due to large quantities of silt and sand debris. Recon teams were directed to precede to the target locations. Due to abnormal topography generated by both the object and SCP-3700, Recon teams descended 10 km before reaching the object, at which time contact with Recon teams 2 and 3 were lost.

Begin Log

List of events:

Check in, recon units descend.

Encounter thick cloud of silt and kicked up sand from battle during 3700. Some turbulence.

Recon 2 and 3 exchange communication about following tail lights.

Camera captures something moving in the silt and sand, looks like a giant hand.

Subs arrive at destination. Report lots of odd sounds, and a bubble around 3704, keeping the silt and sand out.

Subs enter the bubble.

No turbulence as they approach.

Sudden flare of sound and activity, communication lost with each sub one by one, following blasts of light and stills of aquatic machines shaped like fauna.

Exploration Log E-3704-1-001 & 002:

Log 1:

  • Contact regained with Recon 1. Brief status report, details destruction of Recons 2 and 3, and crash into a hangar like area.
  • Command orders exploration of the vessel, prepares to send additional teams and armed subs to deal with automated drones.
  • Team moves into 3704-1. Encounters signs of struggle. really describe atmosphere here, scattered finnfolk remains, eeries metallic creaks, distant high pitched screams.
  • Discover a large room with a map. Statch interprets. Radios start picking up a faint signal from deeper in the vessel. Finnfolk on the roof falls into middle of table, startles group, draws attention of 3456. Recognize the screams from during the battle in 3700, know that conventional weapons do nothing.
  • Recon Team grabs glowing weapons from nearby side armory, makes quick advance through the vessel.
  • Stopped at bottleneck from where 3700-2 pierced the vessel. Cross one by one, 3456 catches up. Manage to hold them off, automated drones sweep in, decimate 3456, log ends when crew reaches lead lined doors.

Log 2:

  • Recon team 1 goes into 3704-1-B via lead doors.
  • Explore small section of outer cylinder, including several abandoned military outposts in advanced states of nature reclamation before encountering Finnfolk nomads.
  • Nomads initially wary, alarmed at presence of humans. Give them very little information about contents of interior regions, but tell them something's wrong.
  • Team makes their way to one of the water high ways. Travels through to second cylinder, then innermost cylinder. Log ends with them surveying the rampant destruction and large numbers of 3456.
