Subject: TL7 Space Missile

I was playing around with Vehicles again, and developed this TL7 missile.
It uses a 14,400kJ UV Chemical laser for its offensive punch and is fueled
with cryogenic hydrogen/flourine which is used for both propulsion and
lasing fuel.  Rules for these are in MA Lloyd's Vehicles errata in the ftp
site.

This missile should be suitable for Hard Science(tm) campaigns.  If used in
conjunction with David Pulver's Vector Wars(tm) rules, it may help to
reduce the scale to 100miles/hex and 1 hex per .05 G accel.


SIM-2 (Space Interdiction Missile-2) TL7
Copyright 1998 by John Fosgett

The SIM-2 weapons system was developed by the United States to provide the
USAF with a weapon to challenge the UN's sovereignity over the off world
colonies and the outer solar system.  The original concept called for a
weapon platform which could maneuver independantly and take the fight to
the enemy while minimizing the risks to the USAF personnel and spacecraft.

The SIM-2 uses a 14.4MJ UV chemical laser in a fully stabilized universal
turret mount, and includes a passive infrared sensor co-axially mounted
with the laser for detecting and engaging targets.  Through its
communications link, the SIM-2 can also function as a remote sensor platform.

Although DARPA and Hughes Missile Systems are both highly confident in the
weapon, the USAF higher staff still has some doubts.  Although fewer than
60 of these weapons have been fielded, plans are already underway to up gun
the basic model with a 230MJ laser.
