Glad you like the design system... I put an external clamp in for another shuttle if needful! Map version of combat system will be covered in supplement!

dST/HP: 50
HT: 13
Hnd/SR: -1/5, air 0/5
Move: 2/c, air 20/1750
SM: +7
LWt: 300

[3] Medium Battery (2 fixed-mount missile launchers)
[4-6] 3 Cargo Holds (a total of 45 tons)

Center:
[1] Armor, Diamondoid
[2] Defensive ECM
[3] External Clamp
[4] 2 Bunkrooms (8 people)
[5!] Medium Battery (2 field-jacketed particle beam turrets)
[6!] Contragravity Lifter

[core] Antimatter Reactor (4 power points)

Design Features & Switches:
Streamlined hull, stealth hull, artificial gravity, gravitic compensators, hardened armor, ajustable force screen, FTL comm/sensor arrays


It was a very tight job, and according to various descriptions the Falcon would need several more system spaces, heh. Wookiepedia says its cargo capacity is 100 tons, but I simply couldn't throw out any systems and replace them with additional cargo bays. I'd probably dump the contragrav lifters first, as they aren't really necessary with 2G of acceleration, but all those landing and takeoff scenes in the movies just cry out for them.

Re: GURPS Spaceships, in use!
 

Quick question...

I'm seeing things like dDR 6 ( = DR 60). Does that mean DR 100 as the normal minimum for spacecraft hulls has been abandoned?

Mark

Re: GURPS Spaceships, in use!
 

Is that normal? I believe you, but that's...quite the hull. the equivalent of 36mm of armor steel is nothing to sneeze at, and rather more than I can imagine is required for a pressure hull.

I don't know how thick an attack submarine's hull is, but I have to imagine that since they're good down to 300m or more (30atm), that is much in excess of what the minimum thickness of a spacecraft hull would be.

Is it DR100 to survive re-entry, perhaps?

Re: GURPS Spaceships, in use!
 

DR 100 was only ever the "minimum" for the underside of a spaceship which would perform aerobraking. IIRC in Vehicles the other sides only required something like DR 20 for vacuum/micro-meteorite survival.

Re: GURPS Spaceships, in use!
 

And even for aerobraking it shouldn't be needed, isn't that what the space shuttle does with a hull that is considerably less then DR 100?

Re: GURPS Spaceships, in use!
 

The space shuttle uses a very expensive, thick, and heavy set of ceramic tiles to protect the underside from the extreme heat of aerobreaking. It could probably be considered DR100 (Fire/Heat only), while being considered ablative when subjected to other kinds of damage. Other space capsules use an ablative heat shield, designed to disintegrate on reentry.
