Starship Components

Introduction

Many of these rules are derived originally from the guidelines published in Galaxy Guide 6: Tramp Freighters. However, these rules are significantly modified from the rules presented in that book. As a result of these modifications, these rules need to be playtested and revised to ensure they are reasonable.

Defensive Components

Hull Plating

Hull plating can be repaired or added to an existing craft to improve the Hull rating of the craft. To calculate the cost of the additional hull plating, multiple the ship's hull rating to be achieved (rounded down) by:

  1. Speeder: 500 credits; 8 hours.
  2. Starfighter: 1,000 credits; 16 hours.
  3. Space Transport: 5,000 credits; 80 hours.
  4. Capital Ship: 20,000 credits; 2,000 hours.

Each pip must be purchased separately. Adding the hull plating is relatively easy, requiring an Easy repair roll of the appropriate type.

For each pip of hull rating added to the ship, the maneuverability rating of the ship decreases by 1 pip. For each full die of hull rating added, the ship's Space speed also decreases by one step (due to the additional weight of the ship). Only 2D of hull plating can be added to a given ship by default; additional hull plating is at the GM's discretion.

Shields

All space-capable ships contain particle shields; without these shields, the ship would likely be destroyed by high-velocity particles within a relatively short period of time. Some ships also equip defensive shields, also known as ray shields, that protect them from blasters, lasers, and other energy weapons. Ships without ray shields are assumed to have 1D-rated particle shields, which are perfectly sufficient to deflect incoming micrometeorites. Ships will ray shields generally operate with 1D-rated particle shields active at all times, though their shield projectors are capable of generating particle shields of the same strength as their ray shields. Shield systems are made up of the following components:

  1. Two or four shield coils that project ray shields out from the ship;
  2. Four or eight particle field projectors that emit particle shields in lobes around the ship;
  3. Two shield generators, one each for particle and ray shields; and
  4. Two or more energy sinks, which absorb and dissipate the energy impinging upon the shields themselves.

Shield coils absorb feedback from the impact of weapons or particles on the shield itself. They are designed to overload and pop, saving the rest of the system (like a fuse). Coils are inexpensive and quick to replace as a result.

Engine Components

Components listed here affect vehicle speed, hyperspace transit times, and vehicle maneuverability. Both upgrades and system repair components are listed.

Ion Drives

Ion drives provide primary sublight spaceflight (and in-atmospheric flight, for atmospheric-capable ships). Ion drives consist of the following components:

  • A powerplant used to generate the power required to propel the ship;
  • One or more thruster coils, used to channel the thrust and keep the flow laminar and efficient;
  • A flow controller computer, used to control the amount of power fed to the engine for smooth flight;
  • One or more thruster actuators, used to control the engine bell shape and direction to maintain the desired flight profile; and
  • One or more engine housings, shielded plating to contain the thruster output and deflect hard radiation from the crew compartment.

Though some ships do mount single engines, most starship manufacturers rely on multiple engines to keep costs down and improve ship reliability. Mounting two identical engines on a ship improves the space rating by 1 step; mounting four improves it by two steps; mounting 8 improves by 3. In practice, many starfighters mount 2 engines, and many space transports use 4, though there are exceptions. Capital ships often use larger clusters of engines, some mounting as many as 8 large engines. For simplicity's sake, assume that dissimilar engines use only the power rating of the largest-mounted engine(s). Clusters of more than 8 engines do not improve the speed of a vessel.

Engine scale matters considerably when discussing ion drives, since ion engines are essentially reaction drives, though they are highly-efficient reaction drives. For each jump in scale, add 3 steps to the effectiveness of the engine; for example, mounting a single capital-scale ion engine rated for Space 4 on a starfighter-scale ship grants a space rating of 10.

Ship's engines require annual overhauls costing 1% of the base engine cost and requiring a base 10 hours of work. Failure to perform the overhaul introduces gremlins to the engine until the engine can be overhauled and repaired (doubling the cost of the overhaul).

Upgrade Cost

Ion drives may be upgraded up to double their base speed value by running the engine hotter than recommended. For each increase in speed desired, roll the appropriate repair skill at a base Moderate difficulty; 5 successes are needed. Each additional step beyond the base rating of the engine adds +10 to the difficulty of the modification. Each step in speed requires components costing 5% of the base engine cost for the desired speed rating and requires a base 40 hours of work. Any failed rolls or mishaps during this time introduce gremlins to the engines (specifics left to the GM).

Example Gremlins

TODO example gremlins for Ion Drives

Maneuvering Thrusters

Maneuverability repairs and upgrades use the same system, since any damage to a ship's maneuverability results in loss of maneuverability dice. When repairing a ship using purchased components built for that type of ship, the repair roll difficulty is reduced to Moderate and the cost is reduced by half.

To increase a ship's maneuverability by one pip (or from 0D to 1D), multiple the ship's hull rating by the die of maneuverability to be achieved, both rounded down. This gives you a cost multiplier. Multiply this by the following value to determine the cost and duration of the resulting modification:

  1. Speeder Scale: 100 credits, 8 hours
  2. Starfighter Scale: 500 credits, 8 hours
  3. Space Transport Scale: 1,000 credits, 20 hours
  4. Capital Scale: 10,000 credits, 100 hours

Improving maneuverability requires a Difficult repair check, and each pip must be purchased and installed separately. The maximum maneuverability for a given ship is 3D higher than the base maneuverability rating for that ship type. Failures and mishaps during the upgrade process result in gremlins, the details of which are at the GM's discretion.

Example Gremlins

TODO example gremlins for Maneuvering Thrusters

Hyperdrives

A full hyperdrive unit allows the vehicle in question to transit hyperspace, travelling between solar systems. Hyperdrive units are available in three scales: Starfighter, Space Transport, and Capital. Though a larger hyperdrive can be placed in a smaller vessel (taking up a considerable amount of space in the process), this provides no mechanical benefit; a larger hyperdrive only allows for the controlled movement of more tonnage through hyperspace, not for faster transit speeds.

Hyperdrive components are listed separately here as well. In general, a hyperdrive unit consists of:

  • A motivator, which modulates the field that pushes the ship into and through hyperspace;
  • 2 to 4 field generator coils, which project the hyperspace field around the ship;
  • A mass detector array, which scans for mass shadows in hyperspace along the transit path of the ship; and
  • A mass detector interrupt, which cuts in to collapse the hyperspace field if a mass shadow is detected in the path of transit.

Component Cost % Repair Difficulty Repair Duration
Hyperdrive Motivator 75% Difficult 40 hours
Field Coil 5% Easy 1 hour
Mass Detector Array 25% Moderate 10 hours
Mass Interrupt 10% Difficult 4 hours

Upgrade Cost

Hyperdrives may be upgraded up to 2 steps from their base level. Performing these upgrades requires custom-treating the motivator and coils to withstand higher energies during transit. This requires a shop environment and takes a base of 200 hours of work for the first step (e.g., x2 to x1). To succeed, you must make 5 Heroic repair rolls. For each missed roll, the modified hyperdrive acquires a gremlin (at the GM's discretion); any mishaps also grant the hyperdrive a gremlin. Hyperdrives modified below x1 automatically gain one gremlin per step. For the second step of modification, the base duration and number of rolls required are doubled, and all rolls are at +10 difficulty. To attempt each step costs 25% of the base value of the hyperdrive (for component modification).

If an upgraded hyperdrive is damaged, you will need to either acquire modified parts or modify the replacement parts to work with your modified hyperdrive unit. Modifying the part in place doubles the base repair duration and adds a +10 to the repair difficulty.
