[gurps] [VEHICLE] of the week 663 – GEV-APC (jump-capable)

[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

  This bird is probably a day late, but I wanted to try it out anyway.
I don't think normal hovercraft are suitable for urban areas - either 
there are roads and you need no air cushion or there is rubble and an 
air cushion has problems. According to Vehicles, a GEV skirt is not 
strictly necessary to benefit from the ground effect, even if it is 
more effective. So I went ahead and wrote a skirtless GEV with just 
enough power to truly fly on afterburner ...

GEV-APC (jump-capable) v1.0 (TL8)
  Copyright 2007 by Onno Meyer

  It would be difficult to lift an armored vehicle on vectored thrust 
alone, so this APC uses the ground effect a few feet from the surface 
to cruise along. Afterburners on the turbofans allow the APC to jump 
over obstacles. 
  The APC carries a pilot, a gunner and ten troops. It is armed with a 
25mm autocannon in a remotely operated, overhead turret and two 250-lb. 
hardpoints for gun packs, rockets or missiles. The strong IR signature 
leaves the GEV-APC vulnerable to AA systems, but it could be used in a 
cyberpunk world to intimidate the rabble. 
  The turbofans burn 300 gallons of jet fuel per hour in GEV mode and 
1,200 gallons per hour in VTOL mode. A load of fuel and ammunition is 
$9,000 (excluding hardpoint loads). 

Subassemblies: Body +4, full-rotation Turret +1. 
Powertrain: Four 5,000-lb. vectored turbofans with afterburners; 
  12,000-kWs advanced batteries.
