Vessel Registry & Schematics
Technical specifications for documented Seam-traversal vessels. ISCA exploration-class, SNG commercial, and ISA-CID diplomatic configurations. All specifications are canon-accurate from published works.
ISV Endurance
Meridian-Class Deep Explorer (EX-01)
Spent Light
First of the Meridian class, built at the Houston-orbital yards. Sabotaged on her maiden voyage and flung past the edge of the charted network — her aft third sheared away at the collars. She never fully recovers: patchwork plating, cannibalised systems, dead reckoning the whole way home. Sister ships: Resolute III, Endeavour, Fortitude, Tenacity.
length
Modular hull (sectioned at structural collars)
crew
~240 (crew, Geneva delegation, science team, Nhál delegation)
propulsion
Harmonic array — fold drive (deep-explorer rating)
armament
Close-defence magazine, point-defence suite
classification
ISCA-FC flagged deep-survey explorer
ISV Resolute
Exploration-Class Vessel
The Long Watch
First of class. Built at Houston Interstellar Yards. 312-metre needle built around a forward 84-metre harmonic array, with four secondary arrays at the hull quarter-points for four-vantage topology. Sits deep — half her mass below the waterline. Designed for 2–4 year continuous deep-frontier deployment.
length
312 m × 84 m beam
crew
34 · 11 decks · all private cabins
propulsion
Dual Seam chamber (primary + backup)
armament
Boundary-disruption arrays (dual-use science/defence)
classification
ISCA Exploration-class · Hull 001
ISV Resolute II
Exploration-Class Vessel (Architect Hybrid)
The Long Watch
Rebuilt at Junction-23 from the original Resolute's wreckage fused into an Architect-residual derelict. The only canonically energy-armed vessel in the fleet. The hull is the derelict's — angular, rectilinear, taller in the corridor — and the salvaged human bridge sits two degrees off level, the ship's signature.
length
287 m × 76 m beam
crew
28–32
propulsion
Derelict Seam chamber · topology-substrate
armament
Architect-residual energy lance + topology-modification shield
classification
ISCA Exploration-class · Architect-residual hybrid
NV Erika Magnusdóttir
T-class Traverse Vessel (Institutional)
The Drift
The line-vessel of the ISNA institutional fleet — the canonical institutional shape against which the SNG commercial ships are measured. Two-stack array; observation deck retained from the 2127 design. Svalbard Shipyard build.
length
128 m · 6 decks
crew
15 (15–20 capacity)
propulsion
Harmonic array (gen-2, two-stack)
armament
None (survey configuration)
classification
ISNA institutional deep-field survey
NV Persistent Error
T-class Traverse Vessel (Third Generation)
The Drift
The Erika Magnusdóttir's four-stack successor — a run ship, not a diplomatic vessel, sent on the first deliberate first-contact mission because her First Navigator knows how not to break it. Crew-named after a 0.012% error no one could explain.
length
142 m
crew
18–22
propulsion
Harmonic array (3rd-gen), four-stack phase-locked
armament
None (survey / contact-protocol configuration)
classification
ISNA T-class · 0.012% drift envelope
NV Karl Vidar Pedersen
SNG Pedersen-class Commercial
The Outer Run
Standard SNG commercial-route vessel. Regular stops include Junction 14-B, Junction 19, Junction 8-C, and Junction Q-3.
length
142 m × 28 m beam · 4,200 t
crew
11–13 (15 max)
propulsion
Harmonic array (2nd-gen → 3rd-gen by B4)
armament
None
classification
SNG commercial-route certified · Hull SNG-T-2127-02
Anchorage Patchwork Hull
Reconstruction
Spent Light
An ISCA-TI intelligence reconstruction of an Anchorage clandestine-fleet vessel, built from fragments — no class, no registry, no two alike. A hull cut from donor ships and welded into a biography of the ships it was scavenged from.

Construction Schematic
Spent Light
How a kilometre-class deep explorer comes to be: a Meridian hull in its orbital assembly cradle, dwarfing the tugs that build her. Section-mated, collar-joined, and never once on a planet. The scale of the Endurance, drawn honestly.

Threat Assessment
Spent Light
A sensor reconstruction of the enemy: rail penetrators, pattern-round magazines, wake-mapping doctrine. Approximated, unconfirmed, and out-gunning everything the Endurance has left.

Blueprint
The Reach
Captain Cross's armed explorer: a lifting-body hull that makes planetfall whole, kinetic mounts precise enough to act as a moving catcher, and the fold array of a true explorer. What a fleet built to discover looks like when it has to learn to fight.

Vessel specifications compiled from series bibles and published canon. Schematics are simplified representations showing major systems layout. T-class designation refers to traversal-capable vessels with harmonic-array propulsion. Generation numbers (gen-2, gen-3, gen-4) indicate harmonic array iteration and capability. ISCA-flagged vessels carry diplomatic credentials; SNG vessels operate under commercial license.
