[gurps] [VEHICLE] of the week 710 – Heavy Tilt-Jet Gunship

[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

Heavy Tilt-Jet Gunship v1.0 (TL9)
  Copyright 2008 by Onno Meyer

  Some cyberpunk games proclaim that vectored thrust aircraft are more 
efficient than fixed or rotary wing aviation. That seems unlikely, but 
sometimes style goes over substance ...
  The Gunship is the armed variant of the Heavy Utility Transport. Her 
cargo bay mounts a laser, a 20mm cannon and a 100mm mortar, all firing 
to the port side. Vectored turbofans make it unnecessary to circle the 
target area, but the broadside configuration provides access space for 
reloading and maintenance. Corporate security forces like the pinpoint 
accuracy and low collateral damage of the laser, while regular forces 
appreciate the armor penetration of the 20mm cannon.
  The turbofans burn 240 gallons of jet fuel per hour of routine use. 
The standard ammo mix and a full load of fuel are $113,350.

Subassemblies: Body +4, six retractable Wheels +0, two Wings +2, two 
  Pods +2. 
Powertrain: Two 12,000-lb. vectored, afterburning, super turbofans;
  6,345,000-kWs rechargeable power cell.
Fuel: 1,200 gallons jet fuel (fire 10).
Occ: 6 RCS.

Design Notes
  Body is 1,000 cf, with very good streamlining. Wheels are 50 cf, 
retract into body. Wings are 96 cf each. Pods are 36 cf each. Structure 
is medium and expensive. Armor is expensive composite. Self-sealing 
tanks. Sealed structure. Computerized controls with duplicate maneuver 
controls. There are 288 cf of empty space in the body. A usual ammo load 
are 1,250 rounds APFSDS and 1,250 rounds HE for the cannon and 200 
rounds HE, 100 rounds CLGP HE and 200 rounds Starshell for the mortar, 
all stored in the body. Empty weight is 24,000 lbs.

  The vehicle uses the design rules from Vehicles [second edition, third 
printing, Dec 2004 errata], VXi and VXii (including the armor volume and 
ceiling rules) with the text format from Vehicles Lite.
