Re: Pre-made spaceships?
 

Looks good.

For short range I would go for 2 Fusion Torch (Water) and 5 tanks (cheapest design and fuel is free)
OR 3 High thrust Fusion Torch (Hydrogen) and 3 tanks (if you need the space)

both of which give 3G performance and an hours combat endurance. [edit: assuming TL11^ performance]

or for long range: go for 4 normal Fusion Torch (Hydrogen) and as many tanks as fit.

Re: Pre-made spaceships?
 

I forgot to type that fighters in general would be dropped out of carriers, so they don't generally have much fuel in - they are hit-and-run ships, not hunting vessels. A dedicated "hunter" ship wold probably be like this:

SM: 6
Front
[1-2] Armor: Nanocomposite
[3-4!] Weapons: Major Battery
[5] Array: Tactical
[6] Fuel Tank
[core] Control Room
Center
[1-2] Armor: Nanocomposite
[3] Power Plant: Fusion
[4!] Weapons: Major Battery
[5-6] Fuel Tank
Rear
[1-2] Armor: Nanocomposite
[3-6] Reaction Engine: Fusion Torch
Design Options

* Hardened Front Armor
* Hardened Center Armor
* Hardened Rear Armor

with two missile launchers in the front and an improved rapid fire laser in the central hull turret.

How restricted are simple AIs in your campaign? You could replace physical gunners with computer programs; to me it makes a lot of sense especially for point-defense systems.

Re: Pre-made spaceships?
 

So have you decided on the setting ship component details yet?

I currently see TL10 standard plus the following super-science items:

• hardened armor
• TL11^ Fusion Torch drives - are these allowed in a habitable planets atmosphere?
• single Stardrive for interstellar ships
• Artificial gravity [edit]

Re: Pre-made spaceships?
 

And realistically humans couldn't react fast enough for point defence with missiles moving at miles-per-second anyway.

Re: Pre-made spaceships?
 

Well, I'm thinking about limiting programs to skill 12. Good for firing that extra weapon when everyone else is too busy, not so good to thrust it to save your life in point defense. ;-)

Pretty much, but I've still have to specify some details.

Is it superscience?

Fusion torches are actually TL 10^. Super fusion torches are TL 11^, but they have no place in my games. ;-)

Yeah, that were for simplicity: my players are new to GURPS in general, no reason to bother them with 0-grav operations or multiple stardrives.

Re: Pre-made spaceships?
 

Hmm, I am not sure. Hardened Armor looks superscience, but isn't listed as superscience.

Oh, I thought you were using the TL11 version for fuel endurance. If you are only using two tanks of H2 for interplanetary travel using TL10 tanks at 15mps each, then an Earth-Mars voyage will take around 19 weeks and that is orbit-to-orbit, not surface-to-surface.

Re: Pre-made spaceships?
 

Why would it be? Neither the description in Spaceships nor Characters implies any such thing. In fact, modern tank armour is effectively hardened vs HEAT rounds.

I saw the Hyperdense and thought Traveller superscience. Is hyperdense normal science?
