Interesting Todd, thanks
Missile guidance ... sounds like the Nike series for the earlier guidance
or the HAWK (Homing All the Way Killer) which with its large warhead made
up for any lack of accuracy with a large kill zone of about 400m IIRC.
RE: lasers ... for Traveller you have to mind the fuel I think, RL for the
Boeing Airborne Laser (now defunct) but smaller systems I think get away
with whatever the vehicle/vessel is using.
