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. With a slight delay, old vehicles appear at http://omeyer.gmxhome.de/GURPSnet_files/summary.html Onno Meyer, 2006-04-01
Self-Propelled Trebuchet v1.0 (TL7 7/8th) Copyright 2006 by Onno Meyer Trebuchets are great for battering down castles, but they are hardly mobile. Moving an assembled trebuchet into firing range can be just as risky as building one under the eyes of the enemy. The self-propelled trebuchet is the solution to all these problems. With a 640 kW diesel engine and a fully tracked chassis, the SPT can deal with fields, unimproved roads and small ditches. The fire control system consists of a ballistic computer, a laser rangefinder and GPS, inertial navigation and conventional navigation systems for accurate, aimed fire within seconds of a halt. The datalink system can tie into the battery fire control net. The SPT carries six crew (commander, driver, radio operator, gunner and two loaders) under armor and NBC protection. 27 assistant loaders are required to operate the trebuchet - they will have to ride in the ammo trucks or march on foot. At routine travel speed, the engine burns 22.4 gallons of diesel per hour. A full load of fuel and ammunition is $1,920. Subassemblies: Body +4, full-rotation Turret +4, two Tracks +3.
