What follows is a step-by-step procedure which will allow you to create
starships for use in the Star Wars RPG. Start at the beginning, and go
through each section in order, only skipping those that you deem un-
necessary. The final result will be your very own customized ship.
-----------------------------------------------------------------------
2. Modifiers
Below are several factors which will be multiplied into certain formulas
during the construction process. For the sake of brevity, they are given
the following abbrevations:
AM Age Modifier
CM Current Mass
FC Fire Control
GF Gunnery Factor
GM Guidance Modifier
ML Mass Limit
PM Propulsion Modifier
PPF Payload Penalty Factor
PU Power Unit
SM Scale Modifier
TM Total Mass
WM Warhead Modifier
Please note that all mass calculations are in metric tons, while power
is measured in power units and cost in standard credits.

2.1 Determine what type of starship you want
The type of starship is of great importance since it determines
some of the options available later.
If you are not sure of what type of ship you want, look at
some ships made by WEG in order to get some ideas.
2.2 Select Starcraft's Scale
Select the scale from the following chart. The scale is very
important in order to determine the maneuverability and the
ability to withstand damage. The Scale Modifier is also used
to determine scale for weapons and some of the equipment.
Scale Category Scale Modifier (SM)
Character Scale x0.25 1)
Speeder Scale x0.5 1)
Walker Scale x0.75 1)
Starfighter Scale x1
Capital Scale x2
Death Star Scale x10 1)
1) Included to make it possible to use weapons from this type
of scale. Starships are normally not built in this scale,
the only exception is Death Star-scale but the SCS is really
not suited to calculate ships of that magnitude.
2.3 Determine the Mass Limit (ML) for the starship
The Mass Limit (ML) sets a theoretical limit on how much a
starship weighs unloaded. In other words, without any cargo
or other type of payload carried.
The Mass Limit can be calculated by using one of two methods:
* Method 1:
Ship Category Mass Limit Formula
Starfighters : Length^1.1 + Cargo / 10
Starfighter Scale Ships : Length^1.5 + Cargo / 10
Capital Scale Ships : Length^2.0 + Cargo / 10
Note: The cargo value used in the calculation above must be the
same as the one used in chapter 8.11.
IMPORTANT: The amount of cargo is NOT added to the Mass Limit
when adding all masses together. It is only added to
the Total Mass Limit, see chapter 2.4 for details.
* Method 2: Calculate the real volume and divide it by three.
2.4 Determine Total Mass Limit
The Total Mass Limit (TML) sets a theoretical limit on how much
a starship weighs fully loaded, i.e. with max cargo and maximum
external payload.
Ship Category Total Mass Limit Formula
Starfighters : Mass Limit x 1.2 + Cargo
Starfighter Scale Ships : Mass Limit x 1.2 + Cargo
Capital Scale Ships : Mass Limit x 1.2 + Cargo
* Adjusted Rating
The Adjusted Rating reflects how the ship handles when taking
into account cargo and any other type of payload.
Current Mass (CM), is ML plus any cargo and external payload.
Payload Penalty Factor (PPF) = ML / CM
Sublight Speed; Space : PPF x Space Rating
Atmosphere : PPF x Atmosphere Speed Rating
Maneuverability : PPF x Maneuverability Rating
Note 1: Always calculate maneuverability in pips.
Note 2: Take the adjusted atmosphere rating and look at chapter
3.3 in order to get the new atmosphere speed of the
ship. Always use the value which is closest to the
adjusted rating.
Example: A ship with a ML of 150 tons and cargo capacity of 100
tons has a TML of 150 x 1.2 + 100 = 280 tons.
If flown fully loaded, up to the TML, the PPF becomes
150 / 280 = 0.536.
The ship has a space rating of 4 and a maneuverability
of 2D. Using the PPF, the new adjusted speed becomes
0.536 x 4 = 2.144 or 2, while maneuverability becomes
0.536 x 6 = 3.216 or 3 = 1D.
The original atmosphere speed was 280;800 kmh, and
it became 0.536 x 280 = 150.08, 0.536 x 800 = 428.8.
The adjusted atmosphere speed is 150;430 kmh.
2.5 Determine Starcraft's Age Modifier (Optional Rule)
Sets the time period for when the starcraft was built OR the
level of standard for any replacement systems installed after
construction.
Time Period Age Modifier (AM)
Mass: Cost:
Old Republic x2 to x9 x0.8-0.1
Clone War x1.1 x0.9
New Order x1 x1
New Republic x0.9 x1.1
Dark Empire x0.8 x1.2
