This is a weekly posting with GURPS vehicles (and the like) to the
GURPSnet mailing list. I grant the permission for all non-commercial
redistribution of my work, but I would like to know if you put it on
a website or the like. The files at omeyer.gmxhome.de are down until
I fix the automatic PDF generation, which should be one of these
days - see sourceforge.net/projects/gurpsml

The 'double issue' of this week presents the same ship twice, once as
a Vehicles design and once with the Spaceships rules. The twin versions
are not interchangeable in the same game, but they have a similar look
and feel in both systems.
300-ton Pirate Starship v1.0 (TL10)
Copyright 2009 by Onno Meyer
This starship uses one obvious violation of physics as we know it (the
hyperdrive) and a few less obvious ones to allow interstellar travel and
adventures. The pirate is a converted merchanter, captured by a smaller
pirate ship and refitted with components from both ships.
The new pirate ship is armed with a 900-MJ x-ray laser from the pirate
which captured her and two 36-MJ xasers from her original armament. Most
of the cargo hold was converted into reaction mass tanks, a spartan brig
and a hydroponic life support system for up to forty people. The cockpit
was expanded into a bridge with extra sensor and gunnery consoles. The
quarters were stripped of all excess mass to maximize delta-V, but the
pirates have enough space to divide them into individual cubicles with
lightweight partitions between them.
The fusion rockets use 400 gallons of reaction mass per minute.
Subassemblies: Body +7, twelve retractable wheels +3.
Powertrain: Three 400,000-lb. vectored fusion rockets; 750-ton
hyperdrive; 25-kW RTG; 10,000-kW fusion reactor; three 90,000,000-kWs
rechargeable power cells; 45,000,000-kWs rechargeable power cell.
Fuel: 32,000 gallons water.

Cheap 900-MJ Xaser [Bod:F] (18 shots) +2.
Equipment:
Body: Spin hull (3-yard radius); full stabilization and casemate mount
for 900-MJ Xaser; full stabilization and cyberslave mounts for 36-MJ
X-Ray Lasers; two extreme-range radios; extreme-range laser
communicator; 1,000-mile AESA; 4,000-mile, air-search radar; two
1,600-mile thermographs; 1,600-mile radscanner; x200 astronomical LLTV;
x400 astronomical LLTV; set of navigation instruments; IFF; four
inertial navigation systems; three HUDWACs with pupil scanners; advanced
radar/laser detector; deceptive jammer, rating 12; two C6 hardened
microframes; 10 terminals; two full fire suppression systems;
engineering mini-workshop; automed; cargo ramp; 5-man airlock; brig, 10

Design Notes
Cheaply made (to represent age). Body is 30,000 cf, with very good
streamlining and lifting body. Wheels are 1,500 cf, retract into Body.
Structure is heavy, standard. Armor is standard composite. Sealed.
Computerized controls with duplicate maneuver controls. 3,191 cf of
empty space. Empty weight is 280,000 lbs.

The vehicle uses the design rules from Vehicles [second edition, third
printing, January 2007 errata], VXi and VXii (including the armor volume
rule) with the text format from Vehicles Lite.
300-ton Pirate Starship, Spaceships Version v1.0 (TL10^)

The new pirate ship is armed with a 100MJ laser from the pirate which

[2-4] Habitat (2 bunkrooms each).
[5!] Major Battery (one fixed mount with 100MJ UV Laser).
[6!] Tertiary Battery (two fixed mounts with 3MJ UV Lasers, 14
tons cargo).
[core] Control Room (C7 computer, comm/sensor 6, and 3 control
stations).
Central Hull System
