Starbase Construction Rules

[Captain Leana Craig]

This is my attempt at creating some station construction rules for CODA.

I tried to get a decent format three times but to no avail.

Any comment or flames are welcome.

I will be posting DS9, the movie era Spacedock and the TNG Starbase 73(big Spacedock)

Starbase/Station Construction Rules


Size Height or Width Space Structure
10 8,000-9,999m 221 260
9 7,000-7,999m 209 240
8 6,000-6,999m 197 220
7 5,000-5,999m 185 200
6 4,000-4,999m 173 180
5 3,001-3,999m 161 160
4 2,000-2,999m 149 140
3 1,000-1,999m 137 120
2 500-999m 125 100
1 200-499m 112 80

Warp Capable Design
A Station that can travel at warp (see below) must have a specially designed hull. 10+size

Cargo Units:
Every Station has 40 times its size in cargo units at no cost. Twenty extra cargo units may be purchased for each additional point of space spent.

Operation Systems and Life Support Systems:

Class Size
Class 1 4+Size
Class 2 7+Size
Class 3 9+Size
Class 4 11+Size

Shuttle bays/Docking Ports

Shuttlebays may be bought at the normal cost of two points of space. Each shuttlebay can accommodate 3xsize in shuttlecraft. Vessels of size three and larger requires docking ports.

Docking Port: Two points of space. Each docking port can accommodate ONE vessel of up to size seven. To accommodate size eight to ten vessels requires the expenditure of one point of space per docking port that can accommodate these huge vessels. Docking ports can be bought to simulate internal docking facilities, such as in Earth’s Spacedock.

Transporters:

A station gains a base of four transporters and one of each type per point of size for free. Stations can purchase two additional transporter of each type at a cost of one space.


Propulsion Systems:

Normally a station does not possess any impulse or warp drives. If the station is to be warp or impulse capable, then warp and impulse propulsion systems must be bought. If a warp system is purchased, the designer must still purchase a station power system.


Starbase/Station Impulse Systems
Class Cost Max .c Reliability Availability
Class 1 12 0.1c A 2284
Class 2 16 0.2c B 2348
Class 3 20 0.25c B 2365

Starbase/Station Warp Systems
Class Cost Stan/Sust/Max Reliability Max Size Availability
Class 1 18 1/1.8/2 A 1 2315
Class 2 25 1.5/2/3 A 2 2326
Class 3 32 2/3/4 B 2 2359
Class 4 39 2/4/5 C 2 2370

Station Power Systems

Due to the lack of matter/antimatter reactors powerful enough to power even the smallest stations. A station must use massive arrays of fusion reactors instead.

A stations power system costs 10+size.

Tactical Systems

A station may mount any type of beam or missile weapon. Stations may also mount Type XI and XII Phaser Arrays.

Type Cost Offensive Value Minimum Size Availability
Type XI 7 11 2 2368
Type XII 8 12 4 2369

Shields Systems

Grid Cost Protection Base/Max Threshold Reliability Availability
Class 1 6 13 1/2 A 2250
Class 2 8 13 1/3 B 2281
Class 3 11 14 2/4 C 2323
Class 4 13 15 2/4 C 2351
Class 5 15 17 2/5 D 2359
Class 6 20 17 2/6 E 2368

Captain, the weapon reliabilities are off. You add the offense value of beams and missiles together for purposes of determining reliability, so phasers and torpedoes should both have the same rating.

Apart from this very minor nitpick I think this is great stuff.

Have you given any thought to a new "hit location" table for systems damage to use with space stations? As these things are very different from spaceships IMO they deserve their own table.

Another idea maybe worth considering is a new system damage category for Auxiliary Systems (docking ports, cargo, etc.).
A lot of space on a station is taken up by cargo bays, docking pylons, civilian areas, etc., which makes it much more likely for a hit to damage one of these sections than on a spaceship.
Possible outcomes for an "Auxiliary Hit" would be
- damage to the docking ports (can't be used),
- damage to cargo bays (penalty to repairs, as spare parts get destroyed) and
- damage to civilian sections (civilians receive xd6 damage), etc.

I think this system is great, but I have a minor nit on the power systems.

Captain Leana Craig Writes:
"Due to the lack of matter/antimatter reactors powerful enough to power even the smallest stations. A station must use massive arrays of fusion reactors instead."
and:
"If a warp system is purchased, the designer must still purchase a station power system."

I have to disagree with these statements. In trek physics, fusion power is infinitessimally lesser than matter/antimatter (warp core) power. On a starship, fusion reactors are used to power impulse engines and a variety of ship's systems. Warp power is used to power the warp engines and the excess power generated is diverted to run ship's systems.

With this in mind, I would treat a station just like a starship with regards to power. The only change I might make is to require additional power for the docking ports/bays to reflect the needs of the battery recharges and maintenance operations of the starships that will berth there.

If a station has a warp core, then its power needs are probably covered, though most stations will not have or need warp propulsion, so a bunch of fusion reactors would be more practical.

Well, That's my 2 cents.

As usual you were right about the reliabilities.

I will give some thought to a station damage table. I am also trying to think up some station traits, without much success so far.

Welcome to the boards Avatar.

Regarding your statment, you are right, BUT (you knew there would be one ) to date the one station we know about in detail and anicdotial evidence suggests that stations use fusion reactors only. My theory is that its cheaper and safer that a M/AM reactor. If a M/AM reactor breaches you could lose tens of thousands of people on a station.

However If you want to ignore it, go for it. Its your game after all.

All this stuff are just guidline to tide us over until Decipher brings out more info on station construction.

I personally don't like the idea of warp capable stations, but someone will want to try.

[Avatar CO]

Thanks for the welcome. I've been lurking here since LUG trek came out.

For the record, I'm not advocating warp-capable stations, and I agree with the fact that it would be far worse for a station to suffer a core breach than it is for a starship. Even if the core was jettisoned, the station would have severe difficulty clearing the blast radius in time.

My disagreement was with the statement "If a warp system is purchased, the designer must still purchase a station power system."

Also, I would suggest the development of a system for thrusters (hopefully this will be covered in the starships book). Our canon sample station's crew (DS9) had to creatively lower the station's mass in order for station-keeping thrusters to be sufficient to move the station a reatively small distance.

that's all for now

Sadly CODA is too abstract as it stands to accommodate such fine tuning.

As for warp core question, after a bit of thought I have come up with a possible solution.

How about these costs for the warp system. You no longer have to buy a seperate power system. The extra cost buys several small fusion reacters that work in conjunction with the warp core to power the station. The warp core operates on minimum power.

Starbase/Station Warp Systems
Class Cost
Class 1 18+2xsize
Class 2 25 +2xsize
Class 3 32 +2xsize
Class 4 39 +2xsize

[Captain Leana Craig]

As suggested by Lancer, Here is the station damage charts.

Station System Damage Table

Roll System
2 Life Support
3 Shields
4 Operations
5 Sensors
7 Propulsion (if no propulsion use ops hit instead)
6-7 Weapons
8-11 Aux Systems (see table 2 System Damage Track)
12 All systems

Table 2 Systems Damage Track

E Cargo Bay hit (3xdamage destroys that many cargo units)
D Docking Port or shuttlebay unusable and 2D6 shuttles destroyed
C Civilian Areas (3xdamage in civilians sustain 2D6 damage)
B Hull breach (6xdamage. Civilians sustain 2D6+3 damage)
A All secondary systems offline (lifts, shuttlebays, lights etc)

Cargo bay hit +5TN to repair due to destroyed spare parts.
Docking port hit +5TN to repair
Hull Breach +6TN in addition to EVA suit penalty

I will be adding these to the construction rules if you all think its ok.

Auxiliary Systems

Class 1 Size
Class 2 Size+1
Class 3 Size+2
Class 4 Size+3
Class 5 Size+4
