Tramp Destroyer
I made this back in 2012, just after moving up to Seattle. Kinda want to make some fleshed-out renders at some point instead of these color-coded ones, but this will have to do for now. Would you like to read some stories set on/about this vessel? See earlier or later designs? Get more fully realized detailed geometry? Let me know.

Some more work-in-progress renders and descriptions here:

Color code is as follows:

Grey:   Armor (light), drive (dark), and structural.

Orange: Coolant and heat management systems.

Yellow: Power

Green:  Crew

Teal:   Data and sensors

Blue:   Immune (ship robots)

Purple: Storage and cargo

Red:    Weaponry

Here are the notes I made on the system specifications:

Armor: multi-layer composite material, primary structural member

  Highly reflective layers to deflect radiant energy

  high density layers to absorb kinetic impact

  high strength, high rigidity, high toughness layers to distribute forces

  sensor layers for damage feedback and strain analysis + distributed electromagnetic sensing

  active force layers,

    draws power to hold the hull together during heavy manuever or impact.

    Can make the hull "sticky" for camoflauge, requires continued power drain

  Thermal bulk and adjustable hull flattness (rigidity) through water interstitials.

  1 primary hull

  1 secondary hull

Engines: "short range" Anti-graviton emitters, can use interstellar medium for low-impulse drive situations

  use reaction mass for extra thrust, or where ambient matter is scarse

  Incorporate force ports and act as force ports

  can draw in environmental media to replentish reaction mass stores

  21 Main drive ports

  11 reaction mass storage tanks

Force Ports: Dual polarity short range (10km) reaction actuators.

  Used to deflect projectiles into armor, or away from the ship

  Used to de-columate energy weapons

  Used for manuvering, see Engines

  13 force ports

Power: Darkmatter reactors, use magnetic coupling lines for power transmission

  2 primary octant reactors

  5 secondary tetrant reactors

    15 Coolant Nodes, Route coolant, act as junctions

    28 Coolant Patches, radiate excess heat (engines also dump heat)

  Data Lines, All engines, force ports, and sensors wired direct to the primary core

    Each reactor has a data core controlling it exclusively

    Most sensors, engines, and force ports have at least one other secondary controlling data core

    All secondary cores have bypass lines, forming a network independent of the primary core.

    Power umbilical hookup to any power node. Two designed for this at rear.

    Main cargo hatch on lower landing pad.

And here are the notes for the narrative background I worked up:


OMT (Orbital Materials Technology) Locates scrap 3m thick reactive hull

Initial vessel built for TVS (Trans Vesta Systems), vessel named "Shaving"

Second hull (5m thick) located by GW (Gravity Well), sold to OMT

OMT expands vessel under contract for TVS, vessel renamed "Tramp"

TVS withholds payment, OMT loans vessel to GW

GW extorts payment from TVS, destroying minor property

OMT reclaims vessel, recieves payment from GW, surrendurs vessel to TVS

TVS refits internals, threatens GW

vessel stranded after being disabled by GW coverts

GW arrives with aid vessels, TVS refuses aid.

Empire arrives, investigation awards majority stake to GW.

GW purchases remaining interest from TVS.

GW breaks vessel, reuses majority in an outpost "Stunning Refusal"

GW sells 3m hull to vessel AI

AI builds vessel in non-military configuration. Vessel named "Splinter"

-Scenarios- (human equivalent)

ship AI infected (immune deficciency)

Hull breach (cut)

out of reaction mass (slip, fall)

Reentry (slowing from a run)

planetary liftoff (getting up to a sprint)

Long-range duel (firearms)

Skirmish (knife fight)

Defense computer got excited about re-directing fire through non-critical paths in the ship. (unproductive speculation)

Internal dialog of defense system responsibility handoff (delegation)


Tech is tempted by promises of being taught super-complex stuff.


Captain who has seen everything

  Crewer:"We've lost port aux sensors"

  Captain: "Someday we need to get that fixed"

Software Tech who wants to over-optimize systems

  Tech: "We can re-write the force control to get a 5% increase in coverage"

  Captain: "But on reentry, we'll all die?"

  Tech: "I've alraedy made the changes."

Paranoid (by design) Immune system

  Captain: "Why is this combat unit following me?"

  IS: "Enemy boarding action is uprated."

  Captain: "What, so you can roam the ship with live munitions?"

  IS: "I'm sorry Captain. I will uprate the probability of munition malfunction."

  Captain: "Fine; This unit is making me nervous."

  IS: "Yes Captain; It is making me nervous now too."


Immune node in the center of the accelerator loses power when it is firing.

Power and data for Primary Dorsal Sensors run through the observation deck.

Orphaned thermal panel aft of Crew Quarters 3, Hooked to power, but no coolant

Engines 1 and 2 have interfering thermal panels (30cm), need special modifications.

Sec. Data core 1 Runs three sec. generators and two sec. sensor nodes. It feels overloaded.

Sec. Data Core 0 runs sec. reactor 3 with data lines threaded through the main cannon array.

Dorsal Port sector should have a sec. data core, but it was never installed.

Three storage bays only accessable via immune system
