[gurps] [VEHICLE] of the week 732 – Land Dreadnought

[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

Land Dreadnought v1.0 (TL6)
  Copyright 2008 by Onno Meyer

  This super-heavy tank might work on paper, in the minds of delusional 
dictators, or as the mobile headquarters of a cinematic Archvillain. In 
the latter case, there will be exploitable flaws, like a million to one 
chance to hit the thermal exhaust port with a proton torpedo ... 
  The Land Dreadnought has two linked sections, each with a primary gun 
turret and a secondary air defense mount. The hull is ringed by twin MG 
mounts. The forward section holds the crew quarters, with a comfortable 
cabin for the Archvillain and spartan bunks for the henchmen, workshops 
for maintenance, a prison cell for any captured Steel-Jawed Heroes, and 
an artillery plotting table. In a regular army, the luxury cabin would 
be replaced by a small surgery or the like. The rear section holds the 
9 MW main diesel, the 1 MW auxiliary diesel and the fuel tanks. 
  At routine travel speed, the engines burn 400 gallons of diesel per 
hour. A full load of fuel, ammunition and provisions is $145,360.

  Tracks +6, two full-rotation Open Mounts +2.
