[gurps] [VEHICLE] of the week 733 – Planetary Defense Submarine

[Onno Meyer]

  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. My site is down for rebuilding, but sooner or 
later the old stuff should reappear at   omeyer.gmxhome.de

Planetary Defense Submarine v1.0 (TL9)
  Copyright 2008 by Onno Meyer

  The Planetary Defense Submarine uses the oceans of earthlike worlds to 
hide from enemy starships. The Submarine cruises up to 2,000 m below the 
waves, waiting for the order to launch swarms of missiles from periscope 
depth or to fire laser beams from the surface. The highly automated sub 
requires only ten crew, mostly for routine maintenance, and it can stay 
on patrol for many months.
  A full load of ammunition and provisions is $39,168,000. 
  The submarine might fit into Traveller games where contragrav is less 
effective (or more expensive) than described by GURPS Traveller. 

Subassemblies: Body +8, full-rotation Turret +6. 
Powertrain: Two 23,000-kW hydrojets; 50,000-kW fusion reactor; 1,600 
  270,000-kWs rechargeable power cells.
Occ: 10 bridge RCS, 10 bunks.   Cargo: 450 cf.

  The vehicle uses the design rules from Vehicles [second edition, third 
printing, Dec 2004 errata], VXi and VXii (the armor volume rule) with 
the text format from Vehicles Lite. The design decisions assume that the 
ladar detection rules from TS:Under Pressure are used.


Next Week: A mag-lev maintenance car.
