IMPERIAL SCOUT
This is a "100 ton" Imperial Scout Ship for my GURPS Traveller (see /pub/GURPSnet/worlds/traveller.txt).
Basically it takes the stats for a Jump Drive (size weight and fuel) from
MegaTraveller and plops it into a ship designed with GURPS Vehicles (the
fuel and power for the jump drive are assumed to be completely
independent from other systems).  Stats for "grav plates" have also been
taken from MegaTraveller.  GURPS fusion drives are a lot more efficient
and only need refueling every 200 years.  Either...
a)  PC's will never have to worry about running out of manuever fuel or
power (lifesupport needs to be regenerated, a GM should decided how much
reserve a ship has past the minimum 1-2 weeks) and the ship has 5,750 cf
extra space.
b)  Alternatively, a GM may simply use the Traveller rules for maneuver
drive consumption (38,000 gallons, 5,750 cf will give 4 weeks).
The ship uses TL11 except for  computers (TL 8, to fit better with
Traveller level of computing power) and Traveller stuff.  I haven't armed
it.  To add armaments, you will need to add a turret or stick them in
extra space, if any (or sacrifice the Air Raft or Cargo space).
